First Report of Leaf Blight on Paris polyphylla Caused by Ceratobasidium ramicola in China.

Paris polyphylla var. yunnanensisis a perennial herb with significant medicinal properties in anticancer, anti-inflammatory, antibacterial immunomodulatory and antispasmodic activities (Duan et al. 2018). In April 2022, leaf blight disease emerged in Xiangtan City (Hunan), affecting P. polyphylla plantings over an area of 3×104 m2 (27.904°N, 112.918°E). The disease incidence reached an average of 22% of the plants in the field, with infected plants initially displaying water-soaked chlorosis, followed by dry yellow shrinkage that gradually spread from the leaf tips to the entire plant. To identify the causal agent, 20 leaf lesions (4 mm2) collected from 20 plants were surface sterilized with 75% ethanol for 10 s, 5% NaOCl for 30 s, rinsed in sterile distilled water three times, transferred to potato dextrose agar (PDA) plates with lactic acid (0.125%) , and incubated at 28 °C in the dark. Four isolates (PP21 to PP24) with similar morphologies were obtained and purified by the hyphal-tip method. Colonies on PDA initially appeared white with cottony mycelium, later turning light-yellow on the underside. Septate hyphae were branched at right angles with a small constriction at the departure of the branch point and measured 4.16 to 7.93 µm in diameter. Binucleate cells within the septate hyphae were visualized using Giemsa staining (Servicebio, China). For molecular identification, the rDNA internal transcribed spacer (ITS), the second largest subunit of nuclear DNA-directed RNA polymerase II (RPB2), and ATP synthase subunit 6 (ATP6) were amplified from genomic DNA of the isolates extracted by Fungus Genomic DNA Extraction Kit (Bioflux, China) using primers ITS1/ITS4 (White et al. 1990), bRPB2-6F/bRPB2-7.1R (Matheny 2005; Reeb et al. 2004) and ATP61/ATP62 (Kretzer and Bruns 1999), respectively. The ITS, RBP2 and ATP6 of the four isolates were sequenced and deposited in GenBank. BLASTn search of sequenced ITS (PQ187050, PQ187051, PP728052, PQ187052), RBP2 (PQ202833, PQ202834, PP735921, PQ202835) and ATP6 (PQ202837, PQ202838, PP735922, PQ202839) revealed a >99% identity with the type strain of Ceratobasidium ramicola CBS133.82 (NR138368, DQ301708, and DQ301577). For phylogenetic analysis, concatenated sequences of ITS, RBP2, and ATP6 were employed using the maximum-likelihood method in MEGA-X. Based on the morphological and molecular analyses, the isolates were classified into the C. ramicola clade (Bandoni 1979; Samuels et al. 2012; Jeong et al. 2023). To test the pathogenicity of the isolate PP23, mycelial plugs (5 mm in diameter) were placed directly on 15 healthy leaves from 15 three-year-old plants after puncturing with sterile needles. Sterile PDA plugs served as controls. All plants were kept in a greenhouse with conditions of 25°C, 80% relative humidity and a photoperiod of 12 h. After 5 days, all infected plants developed leaf blight symptoms similar to those described above, whereas the control plants remained asymptomatic. The pathogenicity test was conducted three times. C. ramicolawas re-isolated from all symptomatic leaves and confirmed to be identical to the original isolate based on morphology and nucleotide sequences of ITS, RBP2, and ATP6. While C. ramicola is commonly reported to be isolated from diseased cacao, its pathogenicity to cacao remains unknown (Samuels et al. 2012). To our knowledge, this is the first report of C. ramicola causing leaf blight on P. polyphylla, a medicinal herb with significant economic importance in China.

Artemisia afra and COVID-19, the Media Storm Versus the Current State-of-the-Art

AbstractDuring the COVID-19 pandemic, the traditional herbal medicine Artemisia afra Jacq. ex Willd., Asteraceae, was widely used as a remedy, and a true media storm erupted in (South) Africa regarding this matter. Throughout the pandemic, A. afra was not only extensively used, but the herb was also exceedingly difficult to find, which is reminiscent of its historical popularity during the influenza pandemic of 1918. This popularity was further fueled by the launch of Covid-Organics in Madagascar, containing Artemisia annua L., which led to international media attention regarding Artemisia as a treatment for COVID-19. In 2020, millions in research funding were made available in South Africa to study promising traditional medicines, including A. afra, and for the development of an effective remedy which was lacking at the time. Due to its popularity and widespread use, this updated overview of A. afra aimed to collate all scientific data on its chemistry, general in vitro and in vivo biological bioactivity, and its antiviral and Sars-Cov-2 activity reported since 2019. Several studies reported good in vitro antiparasitic activity and in vivo antispasmodic activity. However, many studies reported on biological activities that were many orders of magnitude less active than their positive controls. Surprisingly, not a single in vivo study, patent, or (registered) clinical trial could be found regarding A. afra and COVID-19. Only one study, conducted by a German-Danish research group, reported on the in vitro activity of A. afra extracts against Sars-Cov-2. The results indicated that there was relatively weak activity of 0.09 mg/ml ± 0.03 (selectivity index of 26.22), but the context cannot be established due to the absence of a positive control, which did not exist at the time. Artemisia afra is still widely used as a general antiviral remedy, and in-depth research in this field must be conducted. Several promising results regarding antispasmodic and antischistosomal activity should also be further explored. Graphical Abstract

Lentil Waste Extracts for Inflammatory Bowel Disease (IBD) Symptoms Control: Anti-Inflammatory and Spasmolytic Effects

Background/Objectives: In the contest of agro-industrial waste valorization, we focused our attention on lentil seed coats as a source of health-promoting phytochemicals possibly useful in managing inflammatory bowel diseases (IBDs), usually characterized by inflammation and altered intestinal motility. Methods: Both traditional (maceration) and innovative microwave-assisted extractions were performed using green solvents, and the anti-inflammatory and spasmolytic activities of the so-obtained extracts were determined through in vitro and ex vivo assays, respectively. Results: The extract obtained through the microwave-assisted procedure using ethyl acetate as the extraction solvent (BEVa) proved to be the most useful in inflammation and intestinal motility management. In LPS-activated Caco-2 cells, BEVa down-regulated TLR4 expression, reduced iNOS expression and the pro-inflammatory cytokine IL-1 production, and upregulated the anti-inflammatory cytokine IL-10 production, thus positively affecting cell inflammatory responses. Moreover, a significant decrease in the longitudinal and circular tones of the guinea pig ileum, with a reduction of transit speed and pain at the ileum level, together with reduced transit speed, pain, and muscular tone at the colon level, was observed with BEVa. HPLC separation combined with an Orbitrap-based high-resolution mass spectrometry (HRMS) technique indicated that 7% of all the identified metabolites were endowed with proven anti-inflammatory and antispasmodic activities, among which niacinamide, apocynin, and p-coumaric acid were the most abundant. Conclusions: Our results suggest that lentil hull extract consumption could contribute to overall intestinal health maintenance, with BEVa possibly representing a dietary supplementation and a promising approach to treating intestinal barrier dysfunction.

Antispasmodic Activity of Light-Roasted Coffee Extract and Its Potential Use in Gastrointestinal Motility Disorders.

Antispasmodic agents are crucial in managing gastrointestinal motility disorders by modulating muscle contractions and reducing symptoms like cramping and diarrhea. This study investigated the antispasmodic potential of different coffee bean extracts, including light coffee (LC), medium coffee (MC), and dark coffee (DC), on ileum contractions induced by potassium chloride (KCl), and elucidated their mechanisms of action using in vitro isolated tissue techniques. The results demonstrated that all coffee extracts reduced spontaneous contractions of rat ileum tissue in a dose-dependent manner. Among these, LC showed the most significant reduction in ileum contractions, particularly at higher concentrations. The key findings reveal that LC at 5 mg/mL significantly reduced CaCl2-induced contractions in isolated rat ileum tissue, indicating that LC may inhibit calcium influx or interfere with calcium signaling pathways. The presence of nifedipine, propranolol, and N-nitro-L-arginine methyl ester (L-NAME) have been confirmed in their involvement; they block calcium influx and calcium channels and activate β-adrenergic pathways as part of LC's mechanism of action. The presence of their active compounds, particularly chlorogenic acid and caffeine, likely contributes to the observed antispasmodic effects. These findings suggest that LC exerts its antispasmodic effects by targeting key mechanisms involved in muscle spasms and intestinal motility, providing a potential for managing such conditions.

Phytochemical analysis and investigation of analgesic, anti-inflammatory, and antispasmodic activities of hydroethanolic extracts of Alternanthera dentata, Ocimum carnosum, and Plectranthus barbatus, three species with vernacular names derived from analgesic drugs

Ethnopharmacological relevancePlant vernacular names can provide clues about the popular use of a species in different regions and are valuable sources of information about the culture or vocabulary of a population. Several medicinal plants in Brazil have received names of medicines and brand-name products. Aim of the studyThe present work aimed to evaluate the chemical composition and pharmacological activity in the central nervous system of three species known popularly by brand names of analgesic, anti-inflammatory, antispasmodic, and digestive drugs. Materials and methodsHydroethanolic extracts of Alternanthera dentata (AD), Ocimum carnosum (OC), and Plectranthus barbatus (PB) aerial parts were submitted to phytochemical analysis by HPLC-PAD-ESI-MS/MS and evaluated in animal models at doses of 500 and 1000 mg/kg. Mice were tested on hot plate, acetic acid-induced writing, formalin-induced licking, and intestinal transit tests. Aspirin and morphine were employed as standard drugs. ResultsThe three extracts did not change the mice's response on the hot plate. Hydroethanolic extracts of AD and PB reduced the number of writhes and licking time, while OC was only effective on the licking test at dose of 1000 mg/kg. In addition, AD and OC reduced intestinal transit, while PB increased gut motility. ConclusionsPharmacological tests supported some popular uses, suggesting peripheral antinociceptive and anti-inflammatory effects, while the phytochemical analysis showed the presence of several flavonoids in the three hydroethanolic extracts and steroids in PB, with some barbatusterol derivatives described for the first time in the species.

In this research we have tried to evaluate the formulation of Tinospora cordifolia that shows the Anti-microbial activity for the treatment of Acne vulgaris. We have tested the microbial growth with the help of nutrition broth. We have performed various evaluation parameters of formulation like pH, viscosity, spreadability, physical appearance etc. The results that were obtained were under expectated limits.

Unraveling the multi-faceted role of Rosmarinus officinalis L. (rosemary) and diosmetin in managing gut motility

Ethnopharmacological relevanceRosmarinus officinalis L. (Rosemary) is a popular herb with reported effectiveness against diarrhea, anxiety and constipation, albeit with limited pharmacological evidence. Aim of the studyThe current study was aimed at evaluating the therapeutic potential, possible pharmacological mechanisms of action and active constituents of hydro-ethanolic extract of rosemary (Rs.Cr), as potential anti-diarrheal, laxative and anxiolytic agent. MethodRs.Cr was analyzed through reverse-phase high pressure liquid chromatography (RP-HPLC). Laxative, antidiarrheal, and anxiolytic activities were assessed using in vivo models. Spasmogenic and spasmolytic mechanisms were studied on isolated guinea pig ileum and rabbit jejunum tissues, respectively. Possible role of diosmetin, one of the active constituents of Rs.Cr was also evaluated. ResultsRP-HPLC analysis revealed presence of diosmetin, rutin and apigenin in Rs.Cr. Laxative effect was seen at low doses, which was partially reversed in atropinized mice. The spasmogenic mechanism was mediated by cholinergic and histaminergic receptors stimulation. At higher doses, antidiarrheal activity was evident, with reduction in gastrointestinal motility and secretions using charcoal meal and enteropooling assays, respectively. Rs.Cr also showed dose-dependent anxiolytic effect. The antispasmodic mechanisms were mediated by anti-muscarinic and K+ channel opening-like effect (predominant KATP-dependent). Diosmetin exhibited antidiarrheal and antispasmodic activities, but spasmogenic effect was not seen. ConclusionRosemary leaves have dual antidiarrheal and laxative effects, and as well as anxiolytic activity. In addition, the possible modulation of muscarinic and histaminergic receptors, and KATP channels show it as potential herb to be explored for irritable bowel syndrome. Diosmetin is possibly one of its constituents that contributes to its antidiarrheal activity.

Improved transdermal delivery of novel cannabinoid-loaded patches using Eudragit matrix

The main active cannabinoids in extracts of Cannabis sativa L., cannabidiolic acid (CBDA) and tetrahydrocannabinolic acid (THCA), are known for their pharmacological effects, including anti-inflammatory, analgesic, psychedelic, anti-cancer, and anti-spasmodic activities. This study aimed to develop adhesive cannabinoid-loaded transdermal patches (CLTPs) to enhance the skin permeation of the active cannabinoids, CBDA and THCA, and evaluate their stability. Optimized CLTPs were prepared in 1.5 % (w/w) polyvinyl alcohol-coated petri dishes using a solvent casting technique. The casting solution consisted of mixtures of isopropyl alcohol and ethanol, along with Eudragit®E100, succinic acid, dibutyl phthalate, and permeation enhancers such as oleic acid, isopropyl myristate, mixtures of oleic acid and isopropyl myristate, ethoxydiglycol, sesame oil, and co-polymer (Kollidon®VA64). The physicochemical properties of the patches were characterized by uniformity, thickness, drug content, swelling, and mechanical properties. The in vitro release studies of CBDA and THCA through a synthetic hydrophobic membrane using various release enhancers from these patches were conducted using Franz diffusion cells. Using ethoxydiglycol as a release enhancer demonstrated the highest release profile for both cannabinoids. The steady-state flux values of CBDA and THCA were 3.83 ± 0.45 μg/cm2/h (1.85-fold compared to the control) and 0.72 ± 0.14 μg/cm2/h (1.54-fold compared to the control) at 8 h. The stability studies of CLTPs demonstrated that both remained stable at 4 °C for at least 90 days. In conclusion, transdermal patches containing cannabinoids have been successfully developed and characterized. These findings offer a promising avenue for further investigation of CLTPs, as they could serve as a versatile formulation strategy for pharmaceutical products.

New insights into the characterization of the mechanism of action of hyoscine butylbromide in the human colon ex vivo

IntroductionHyoscine butylbromide (HBB) is one of the most used antispasmodics in clinical practice. Recent translational consensus has demonstrated a similarity between human colonic motor patterns studied ex vivo and in vivo, suggesting ex vivo can predict in vivo results. It is unclear whether the mechanism of action of antispasmodics can predict different use in clinical practice. The aim of the present study is to bridge this gap dissecting HBB's role in excitatory and inhibitory neural pathways. Methods: 309 colon samples from 48 patients were studied in muscle bath experiments. HBB was tested on: 1-spontaneous phasic contractions (SPCs); 2-carbachol-induced contractility; electrical field stimulation (EFS)-induced selective stimulation of 3-excitatory and 4-inhibitory pathways and 5- SPCs and EFS-induced contractions enhanced by neostigmine. Atropine, AF-DX116 (M2 blocker) and DAU-5884 (M3 blocker) were used as comparators. ResultsIn the presence of tetrodotoxin (TTX), HBB and atropine 1 μM reduced SPCs. HBB and atropine concentration-dependently reduced carbachol- and EFS-induced contractions. Inhibitory effects of DAU-5884 on EFS-induced contractions were more potent than of AF-DX116. HBB did not affect the off-response associated to neural inhibitory responses. Neostigmine enhanced both SPCs and EFS-induced contractions. In the presence of TTX and ω-conotoxin (GVIA), neostigmine still enhanced SPCs. Addition of HBB and atropine reduced these responses. ConclusionsThis study demonstrates that HBB inhibits neural cholinergic contractions associated to muscarinic (mainly M3) receptors. HBB has a potential role in reducing colonic spasm induced by the release of acetylcholine from enteric motor neurons and from an atypical source including a potential non-neuronal origin.

Chemical Profiling and Biological Activities of Ziziphus Mauritiana var. spontanea (Edgew.) R.R. Stewart ex Qaiser & Nazim. and Oenothera Biennis L.

Bioactive compounds of medicinal plants, including polyphenols, flavonoids, terpenoids, and alkaloids, are essential sources for developing analgesic, anti-inflammatory, and antidiarrheal drugs. In the current study, secondary metabolites were assessed through phytochemical screening and GC-MS analysis whereas analgesic activity was carried out through hot plate (HP) and acetic acid-induced method (AAI), anti-inflammatory through paw edema model (PEM), and antispasmodic activity via charcoal meal test (CMT) using ethyl acetate and ethanolic extract of Ziziphus mauritiana var. spontanea and Oenothera biennis. The phytochemical screening revealed that the ethyl acetate and ethanolic extracts of Z. mauritiana and O. biennis were rich in alkaloids, flavonoids, tannins, steroids, triterpenoids, and saponins. GC-MS analysis of Z. mauritiana and O. biennis of ethyl acetate and ethanolic extract showed the existence of many bioactive substances at various retention durations (min). These included pharmacologically active compounds such as heptadecane, 2-methoxy-4-vinylphenol, hexadecanoic acid, and tetradecanoic acid. The results of the HP method revealed that ethanolic and ethyl acetate extracts of Z. mauritiana and O. biennis at 300 mg/kg increased basal reaction time significantly (p<0.001) after 90 min. The results of the AAI method revealed that the ethanolic and ethyl acetate extract of Z. mauritiana and O. biennis showed significant (p<0.001) peripheral analgesic activity at the dose of 200 and 300 mg/kg body weight. The dosage of 100, 200, and 300 mg/kg body weight of the ethyl acetate and ethanolic extracts of Z. mauritiana and O. biennis showed significant (p<0.001) anti-inflammatory activity. According to PEM, the ethanolic extract of O. biennis showed the highest reduction in paw volume (73.3%) at 300 mg/kg. The results of CMT revealed that ethanolic and ethyl acetate extract of Z. mauritiana and O. biennis significantly (p<0.001) inhibited charcoal movement at 300 mg/kg. The maximum percent inhibition (67.2%) was shown by ethyl acetate of O. biennis at 300 mg/kg. From the present study, it can be concluded that ethanolic and ethyl acetate extracts of Z. mauritiana and O. biennis have the potential to manage inflammation, pain, and diarrhea-related problems mainly at a higher dose, i.e., 300 mg/kg. The presence of alkaloids, flavonoids, tannins, steroids, triterpenoids, and saponins might be among the responsible bioactive constituents. These plants showed significant medicinal and therapeutic efficacy which are novel. However, further studies are required to investigate the mechanism responsible for the activity.

A Study on the Antibacterial, Antispasmodic, Antipyretic, and Anti-Inflammatory Activity of ZnO Nanoparticles Using Leaf Extract from Jasminum sambac (L. Aiton).

The green synthesis of zinc oxide nanoparticles (ZnO NPs) using plants has grown in significance in recent years. ZnO NPs were synthesized in this work via a chemical precipitation method with Jasminum sambac (JS) leaf extract serving as a capping agent. These NPs were characterized using UV-vis spectroscopy, FT-IR, XRD, SEM, TEM, TGA, and DTA. The results from UV-vis and FT-IR confirmed the band gap energies (3.37 eV and 3.50 eV) and the presence of the following functional groups: CN, OH, C=O, and NH. A spherical structure and an average grain size of 26 nm were confirmed via XRD. The size and surface morphology of the ZnO NPs were confirmed through the use of SEM analysis. According to the TEM images, the ZnO NPs had an average mean size of 26 nm and were spherical in shape. The TGA curve indicated that the weight loss starts at 100 °C, rising to 900 °C, as a result of the evaporation of water molecules. An exothermic peak was seen during the DTA analysis at 480 °C. Effective antibacterial activity was found at 7.32 ± 0.44 mm in Gram-positive bacteria (S. aureus) and at 15.54 ± 0.031 mm in Gram-negative (E. coli) bacteria against the ZnO NPs. Antispasmodic activity: the 0.3 mL/mL sample solution demonstrated significant reductions in stimulant effects induced by histamine (at a concentration of 1 µg/mL) by (78.19%), acetylcholine (at a concentration of 1 µM) by (67.57%), and nicotine (at a concentration of 2 µg/mL) by (84.35%). The antipyretic activity was identified using the specific Shodhan vidhi method, and their anti-inflammatory properties were effectively evaluated with a denaturation test. A 0.3 mL/mL sample solution demonstrated significant reductions in stimulant effects induced by histamine (at a concentration of 1 µg/mL) by 78.19%, acetylcholine (at a concentration of 1 µM) by 67.57%, and nicotine (at a concentration of 2 µg/mL) by 84.35%. These results underscore the sample solution's potential as an effective therapeutic agent, showcasing its notable antispasmodic activity. Among the administered doses, the 150 mg/kg sample dose exhibited the most potent antipyretic effects. The anti-inflammatory activity of the synthesized NPs showed a remarkable inhibition percentage of (97.14 ± 0.005) at higher concentrations (250 µg/mL). Furthermore, a cytotoxic effect was noted when the biologically synthesized ZnO NPs were introduced to treated cells.

Medical Constituents of Ajwain (Trachyspermum ammi) for Human Benefits

Ajwain seed analysis has revealed it to contain fiber (11.9%), carbohydrates (38.6%), tannins, glycosides, moisture (8.9%), protein (15.4%), fat (18.1%), saponins, flavone and mineral matter (7.1%) containing calcium, phosphorous, iron and nicotinic acid. Ajwain fruits yield 2% to 4% brownish essential oil, with thymol as the major constituent (35% to 60%). The non-thymol fraction (thymine) contains para-cymene, γ-terpenine, α- and β-pinenes, diketene, α-terpinene, and carvacrol. Minute amounts of camphene, myrcene, and α-3-carene also have been found in the plant. Alcoholic extracts contain a highly hygroscopic saponin. From the fruits, a yellow, crystalline flavone and a steroid-like substance has been isolated and it also contains 6-O-β-glucopyranosyloxythymol, glucoside and yields 25% oleoresin containing 12% volatile oil (thymol, γ-terpinene, para-cymene, and α- and β-pinene). The principal oil constituents of T. Ammi are carvone (46%), limonene (38%), and dillapiole (9%). Ajwain is administered for curing stomach disorders, a paste of crushed fruits is applied externally for relieving colic pains; and a hot and dry fomentation of the fruits is applied on chest for asthma. Therapeutic uses of T. Ammi fruits include; stomachic, carminative and expectorant, antiseptic and amoebiasis, antimicrobial. Seeds soaked in lemon juice with P runs Amygdalus (badan) are given in curing amenorrhea and it is also used as antipyretic, febrifugal and in the treatment of typhoid fever. The antihypertensive effect of T. Ammi administered intravenously in vivo, and the antispasmodic and bronchodilation actions in vitro showed that calcium channel blockade has been found to mediate the spasmolytic effects of plant materials and it is being considered that this mechanism contributed to their observed result and supported the traditional use of T. Ammi in hyperactive disease states of the gut such as colic and diarrhea as well as in hypertension. Ajwain seeds revealed significant reduction of cough number which may be a result of its potent antitussive effect. The bronchodilator effect of decocted extract of Ajwain on the asthmatic patients’ airways was examined in a subsequent trial study. According to the results, the extract has a relatively bronchodilator effect on asthmatic airways compared to the effect of Theophylline at concentrations used. Ajwain was attributed to have diuretic and antilithiatic activity in ethnopharmacological reports. Accordingly, a human study was performed and in which, seeds of Ajwain were decocted in milk and given orally to volunteers suffering from urinary stone for a nine days period. The results were reported satisfactory against pure ca-oxalate stone. Another activity which has been proved for Ajwain is the antihyperlipidemic property. An in vivo study revealed that Ajwain seeds powder is extensively effective on lipid profile and can decrease total cholesterol, LDL-cholesterol, triglycerides and total lipids. Moreover, organic extract of seeds reduced atherogenic index and increased the level of HDL-cholesterol in albino rabbits. Ajwain was evaluated for the potentiality of antihypertensive and antispasmodic activity. In the related investigation, the aqueous-methanolic extract of the seeds caused a dose dependent decrease in arterial blood pressure in anaesthetized animal models. Furthermore, inhibitory effect on the K+-induced contractions was seen in isolated rabbit aorta and jejunum preparations during the application of Ajwain extract. These findings prove the potential antihypertensive and antispasmodic activity of Ajwain.

Tizanidine: Advances in Pharmacology & Therapeutics and Drug Formulations.

Skeletal muscle relaxants (SMRs) are widely used in treating musculoskeletal conditions. All SMRs, with the exception of baclofen and tizanidine, are on the list of 2023 American Geriatrics Society Beers Criteria® for potentially inappropriate medication use in older adults. In our geriatric practice, off-label use of tizanidine as preemptive analgesia drove us to find recent advances in its pharmacology and therapeutics. An update review of tizanidine was thus presented, aiming to bring the latest knowledge to clinicians and promote further research and practical exploration. Relevant literature up to December 2023 was identified through searches of PubMed, Web of Science, and Embase. Tizanidine, a centrally acting alpha-2 adrenoceptor agonist with both antispastic and antispasmodic activity, shows efficacy in the common indications for all SMRs. From the perspective of drug safety, tizanidine has lower incidences of adverse events (injury, delirium, encephalopathy, falls, and opioid overdose) compared to baclofen, no association with risk of Alzheimer's disease as with orphenadrine, no risk of serotonin syndrome like metaxalone when comedicated with serotonergic drugs, no significant pharmacokinetic changes in CYP2C19 poor metabolizers unlike diazepam and carisoprodol, and no physically addictive or abuse properties like carisoprodol and diazepam. From the perspective of new and potential therapeutic uses, tizanidine has additional benefits (eg, gastroprotection that can improve patient tolerance to nonsteroidal anti-inflammatory agents, anti-neuropathic pain, a key component of multimodal analgesia strategy to reduce early postoperative pain, and anti-tumor effects). New delivery systems of tizanidine are developing to improve the pharmacokinetics of oral products, including buccal patches, transdermal delivery systems, nasal spray, and in situ rectal gel. Tizanidine is an SMR with unique features and may be an optimal initial choice for older adults. There would be more scientific studies, wider therapeutic applications, and new drug formulations in the future.

Medical Constituents of Ajwain (Trachyspermum ammi) for Human Benefits

Ajwain seed analysis has revealed it to contain fiber (11.9%), carbohydrates (38.6%), tannins, glycosides, moisture (8.9%), protein (15.4%), fat (18.1%), saponins, flavone and mineral matter (7.1%) containing calcium, phosphorous, iron and nicotinic acid. Ajwain fruits yield 2% to 4% brownish essential oil, with thymol as the major constituent (35% to 60%). The non-thymol fraction (thymene) contains para-cymene, γ-terpenine, α- and β-pinenes, dipentene, α-terpinene, and carvacrol. Minute amounts of camphene, myrcene, and α-3-carene also have been found in the plant. Alcoholic extracts contain a highly hygroscopic saponin. From the fruits, an yellow, crystalline flavone and a steroid-like substance has been isolated and it also contains 6-O-β-glucopyranosyloxythymol, glucoside and yields 25% oleoresin containing 12% volatile oil (thymol, γ-terpinene, para-cymene, and α- and β-pinene). The principal oil constituents of T. ammi are carvone (46%), limonene (38%), and dillapiole (9%). Ajwain is administered for curing stomach disorders, a paste of crushed fruits is applied externally for relieving colic pains; and a hot and dry fomentation of the fruits is applied on chest for asthma. Therapeutic uses of T. ammi fruits include; stomachic, carminative and expectorant, antiseptic and amoebiasis, antimicrobial. Seeds soaked in lemon juice with P runus amygdalus (badam) are given in curing amenhorroea and it is also used as antipyretic, febrifugal and in the treatment of typhoid fever. The antihypertensive effect of T. ammi administered intravenously in vivo, and the antispasmodic and bronchodilating actions in vitro showed that calcium channel blockade has been found to mediate the spasmolytic effects of plant materials and it is being considered that this mechanism contributed to their observed result and supported the traditional use of T. ammi in hyperactive disease states of the gut such as colic and diarrhea as well as in hypertension. Ajwain seeds revealed significant reduction of cough number which may be a result of its potent antitussive effect. The bronchodilatory effect of decocted extract of Ajwain on the asthmatic patients’ airways was examined in a subsequent trial study. According to the results, the extract has a relatively bronchodilatory effect on asthmatic airways compared to the effect of Theophylline at concentrations used. Ajwain was attributed to have diuretic and antilithiasis activity in ethnopharmacological reports. Accordingly, a human study was performed and in which, seeds of Ajwain were decocted in milk and given orally to volunteers suffering from urinary stone for a nine days period. The results were reported satisfactory against pure ca-oxalate stone. Another activity which has been proved for Ajwain is the antihyperlipidemic property. An in vivo study revealed that Ajwain seeds powder is extensively effective on lipid profile and can decrease total cholesterol, LDL-cholesterol, triglycerides and total lipids. Moreover, organic extract of seeds reduced atherogenic index and increased the level of HDL-cholesterol in albino rabbits. Ajwain was evaluated for the potentiality of antihypertensive and antispasmodic activity. In the related investigation, the aqueous-methanolic extract of the seeds caused a dose dependent decrease in arterial blood pressure in anaesthetized animal models. Furthermore, inhibitory effect on the K+-induced contractions was seen in isolated rabbit aorta and jejunum preparations during the application of Ajwain extract. These findings prove the potential antihypertensive and antispasmodic activity of Ajwain.

Antispasmodic and antidiarrheal effects of Juniperus oxycedrus L. on the jejunum in rodents.

Functional bowel disorders (FBD) have a major potential to degrade the standards of public life. Juniperus oxycedrus L. (J. oxycedrus) (Cupressaceae) has been described as a plant used in traditional medicine as an antidiarrheal medication. The present study is the first to obtain information on the antispasmodic and antidiarrheic effects of J. oxycedrus aqueous extract through in vitro and in vivo studies. An aqueous extract of J. oxycedrus (AEJO) was extracted by decoctioning air-dried aerial sections of the plant. Antispasmodic activity was tested in an isolated jejunum segment of rats exposed to cumulative doses of drogue extract. The antidiarrheic activity was tested using diarrhea caused by castor oil, a transit study of the small intestine, and castor oil-induced enteropooling assays in mice. In the jejunum of rats, the AEJO (0.1, 0.3 and 1 mg/ml) diminished the maximum tone induced by low K+ (25 mM), while it exhibited a weak inhibitory effect on high K+ (75 mM) with an IC50=0.49 ± 0.01 mg/ml and IC50=2.65 ± 0.16 mg/ml, respectively. In the contractions induced by CCh (10-6 M), AEJO diminished the maximum tone, similar to that induced by low K+ (25 mM). with an IC50=0.45 ± 0.02 mg/ml. The inhibitory effect of AEJO on low K+ induced contractions was significantly diminished in the presence of glibenclamide (GB) (0.3 µM) and 4-aminopyrimidine (4-AP) (100 µM), with IC50 values of 1.84 ± 0.09 mg/ml. and 1.63 ± 0.16 mg/ml, respectively). The demonstrated inhibitory effect was similar to that produced by a non-competitive antagonist acting on cholinergic receptors and calcium channels. In castor oil-induced diarrhea in mice, AEJO (100, 200, and 400 mg/kg) caused an extension of the latency time, a reduced defecation frequency, and a decrease in the amount of wet feces compared to the untreated group (distilled water). Moreover, it showed a significant anti-motility effect and reduced the amount of fluid accumulated in the intestinal lumen at all tested doses. These findings support the conventional use of Juniperus oxycedrus L. as a remedy for gastrointestinal diseases.
