Ekplorasi Senyawa Ekstrak Etanol Rumput Belulang (Eleusine indica (L.) Gaertn) Menggunakan LC-MS/MS-QTOF Serta Uji Aktivitas Anti-Diare: In-Vivo

Diarrhea is one of the diseases caused by symptoms of intestinal tract infections due to various microorganisms. Goosegrass (Eleusine indica (L.) Gaertn) is a wild weed that has long been used as a traditional medicine, attributed to its phytochemical compounds such as tannins, alkaloids, flavonoids. This study aims to evaluate the antidiarrheal effects of Eleusine indica extract by comparing six treatment groups: a healthy group, a negative control group (Na-CMC), a positive control group (Loperamide 2 mg), and three variations of the extract dosage. Observations were made over 360 minutes at 30-minute intervals, using a fecal consistency scale from 1 (solid) to 5 (liquid). LC-MS/QToF analysis identified 25 secondary metabolites in the extract, including flavonoids (Schaftoside, Orientin, Vitexin, Tricin), phenolic compounds, and terpenoids. In vivo testing showed that the third dose of Eleusine indica grass extract had the most optimal antidiarrheal effect among the three doses, as evidenced by its ability to reduce diarrhea frequency, decrease fecal weight, shorten diarrhea duration, and improve fecal consistency, approaching the effectiveness of Loperamide 2 mg as a positive control. These findings suggest the potential of Eleusine indica extract as a promising natural antidiarrheal agent.

Synthesis and pharmacological evaluation of heteroarylamide derivatives as potential analgesic, anti-inflammatory, antidiarrheal and cytotoxic agents

Six heteroarylamide derivatives were synthesized in good yields and screened for several biological activities. Compounds 1–5 demonstrated analgesic activity with percentage inhibition of writhing between 77.10 and 95.79 %, comparable to that of the standard aceclofenac having 91.12 % writhing inhibition. Evaluation of anti-inflammatory activity unveiled that compound 4 exhibited 36.9 %, 64.17 %, 82.9 % and 93.9 % inhibition of paw edema as compared to aceclofenac's inhibition of 35.5 %, 78.6 %, 79.3 % and 91.2 % at the 1st, 2nd, 3rd and 4th hours, respectively. Compounds 5 and 6 exerted considerable antidiarrheal effects with 85.00 % and 71.67 % inhibition of defecation at 25 mg/kg dose, respectively, whereas, the standard loperamide showed 85.00 % inhibition. Compounds 4–6 manifested promising activity in brine shrimp lethality bioassay as well as in trypan blue dye exclusion assay, resulting in 10–20 % cell viability on HeLa cell line and compound 5 was found to have the lowest IC50 of 281.96 μM in the MTT assay. Molecular docking analysis suggested that certain macromolecular targets such as cyclooxygenase-2, muscarinic M3 receptor and matrix metalloproteinase 9 (MMP9) might be involved for the observed activities. As predicted by in silico ADME/T analysis, the compounds also possessed good pharmacokinetic properties.

What, how, and why? - anti-EHEC phages and their application potential in medicine and food industry.

Enterohemorrhagic Escherichia coli (EHEC) are pathogens that, only in the United States, cause more than 250,000 foodborne infections a year. Since antibiotics or other antidiarrheal agents may increase the hemolytic-uremic syndrome (HUS) development risk, currently only supportive therapy, including hydration, is used. Therefore, many methods to fight EHEC bacteria focus on their use in food processing to prevent human infection. One of the proposed anti-EHEC agents is bacteriophages, known for their bactericidal effect, host specificity, and lack of cross-resistance with antibiotics. In this review article, we provide an overview of the characteristics like source of isolation, morphology, kinetics of life cycle, and treatment potential of over 130 bacteriophages able to infect EHEC strains. Based on the reviewed literature, we conclude that bacteriophages may play a highly significant role in regulating EHEC propagation. In addition, we also point out the phage features that should be taken into account not only when using bacteriophages but also when examining their properties. This may contribute to accelerating the pace of work on the preventive use of bacteriophages, which is extremely needed in the modern world of the food industry, but also stimulate interest in phages and accelerate regulatory work that would enable the use of bacteriophages also in medicine, to fight the drug-resistant strains.

Phytotherapy for Diarrhea: Bridging Herbal Medicine and Modern Treatment

Diarrhea remains a significant global health issue, responsible for approximately 1.9 million deaths annually, particularly in children under five. Conventional treatment includes oral rehydration and antibiotics; however, phytotherapy, the use of plant-based remedies, offers an alternative or complementary solution, especially for cases involving chronic diarrhea or antibiotic resistance. This paper examines the historical and scientific basis of phytotherapy, its pharmacological mechanisms, clinical efficacy, and potential integration with modern medicine. Despite the lack of robust clinical data for some herbal treatments, growing interest in complementary approaches highlights the need for further research. Phytotherapy shows promise in alleviating symptoms and modulating gut health through anti-inflammatory, anti-infectious, and gut-modulating mechanisms. The integration of herbal medicine with modern treatment protocols could enhance the therapeutic approach to managing diarrhea and improve patient outcomes, especially in settings with limited access to modern pharmaceuticals. Keywords: Phytotherapy, Herbal medicine, Diarrhea treatment, Antidiarrheal agents, Antibiotic resistance.

Antidiarheal Activity of Methanol Seed Extract of Cola Acuminata Schott & Endl (Malvaceae) In Mice

Cola acuminata nut extract has been shown to relax smooth muscles of the intestine in vitro, and this has made the plant popular as a potential antidiarrheal agent. This study aimed at evaluating the antidiarrheal activity of methanolic seed extract of Cola acuminata in mice. The extract was subjected to phytochemical analysis. The acute toxicity (LD50) study was conducted according to Lorke's method. The antidiarrheal activity was evaluated using castor oil-induced diarrhea and charcoal meal method in mice. Groups of mice were orally administered water (10 ml/kg), charcoal, Cola acuminata nut extract (150, 300 and 600 mg/kg), loperamide 2mg/kg, and atropine 1 mg/kg before castor oil. Phytochemical screening revealed the presence of alkaloids, cardiac glycosides, tannins, triterpenes, and saponins. The oral LD50 of the extract was estimated to be 2154 mg/kg. The extract produced a significant p < 0.05 increase in time of onset of diarrhea compared to the distilled water group. The extract produced dose dependent inhibition of the number of wet faeces. Extract at 600 mg/kg had more protection against diarrhea than the Loperamide. The extract did not significantly (p > 0.05) affect the intestinal movement of charcoal meal.

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.

Antidiarrheal effect of Psidium guajava L. extract in acute diarrhea: a systematic review.

Acute diarrheal diseases are a leading cause of childhood mortality and morbidity worldwide. Psidium guajava has been globally used for its antidiarrheal potential. We conducted a systematic review of scientific articles published up to the year 2021, which included in vivo pre-clinical tests and clinical trials involving patients with acute infectious diarrhea to verify the antidiarrheal, antibacterial and antispasmodic effects of galenic preparations or phytopharmaceuticals from P. guajava. PRISMA and Rayyan were used as tools for the selection of studies collected in four databases (Pubmed, Scopus, Web of Science and Science Direct). The keywords used to carry out the search were: 'Psidium guajava', 'guava', 'antidiarrhe*' and 'diarrhe*', joined by Boolean operators 'OR' or 'AND'. The characteristics of studies in animal models of acute diarrhea induction, as well as in vivo and in vitro motility and microbiological tests linked with its main pathophysiological mechanisms, were collected. Twenty-three articles were included. Twenty (87%) of these reported heterogenic preclinical studies, predominating pharmacological studies of efficacy against conventional antidiarrheal agents, which utilized relevant outcomes and models of infectious diarrhea from the top pathogens in the clinic along with classical castor oil-induced diarrhea associated with motility tests. Only three articles (13%) corresponded to clinical trials investigating the efficacy, dose and safety of these preparations. Most studies reported positive results and significant mechanistic evidence from antibacterial, anti-motility, anti-secretory and protective/anti-inflammatory perspectives. However, further studies are needed to define the clinical significance and safety treatment with P. guajava extracts. © 2024 Society of Chemical Industry.

β-Sitosterol Mediates Gastrointestinal Smooth Muscle Relaxation Induced by Coccoloba uvifera via Muscarinic Acetylcholine Receptor Subtype 3

Coccoloba uvifera is a Mayan medicinal plant, and these leaves are used as antidiarrheal and diuretic agents. In the present work, we develop in-vitro, ex-vivo, in-vivo, and in-silico strategies to evaluate several aqueous extracts of C. uvifera leaves. In vitro tests showed that decoction extract (CuDe) presented the best yield and chlorophyll, phenol, and flavonoid content; however, CuDe showed low antioxidant activity (DPPH model). All aqueous extracts exert spasmolytic and vasorelaxant activity in a concentration-dependent manner (ex vivo), and in vivo tests showed that CuDe exerts the best antiperistaltic and diuretic effects. The in-silico analysis suggests that C. uvifera triterpenes act as a ligand of GPCR, and β-sitosterol could act as an antagonist of muscarinic acetylcholine receptor subtype 3 (m3AChR). In the context of aqueous extracts of C. uvifera, β-sitosterol and their heterosides were identified by FTIR and 1H-NMR spectroscopy. The concerted binding of β-sitosterol and other triterpenes within the m3AChR binding site may be relevant for the induction of relaxant effects at the gastrointestinal smooth muscle level. In this context, C. uvifera is a high-value plant species that requires analytical and pharmacological studies to confirm traditional medicinal use.

Evaluation of Medicago sativa ethanol leaf extract for antidiarrheal activity in Wistar rats

Aim: Medicago sativa leaf is traditionally used for the treatment of gastrointestinal disorders in Nigeria. This research investigates the in vivo antidiarrheal activity of M. sativa (Alfalfa) leaf extract in Wistar rats. Method: The study employed three models: castor oil-induced diarrhea, gastrointestinal motility (charcoal meal), and castor oil-induced intestinal fluid accumulation. The phytochemical analysis as well acute toxicity tests were carried out in the leaf extract. Results: The results demonstrate a dose-dependent and significant antidiarrheal effect of M. sativa leaf extract. In the castor oil-induced diarrhea model, the extract reduced fecal frequency, delayed onset, and lowered severity, with the highest effect at 600 mg/kg compared to a positive control (Loperamide). Gastrointestinal motility was inhibited by the extract in a dose-dependent manner, achieving maximum effect at 600 mg/kg, comparable to atropine sulfate. The castor oil-induced intestinal fluid accumulation model revealed a significant decrease in fluid volume at 600 mg/kg, exhibiting a potent inhibitory effect. The oral LD50 values obtained were greater than 5000 mg/kg in rats Conclusion: This study provides compelling evidence of Medicago sativa leaf extract's potential as an antidiarrheal agent in Wistar rats. Further investigations could explore its mechanism of action and safety profile, contributing valuable insights to the development of novel antidiarrheal therapies.

Ambrosia arborescens Mill. (A. arborescens) is an aromatic plant used in traditional medicine as an anti-inflammatory, anti-tussive, anti-rheumatic, and anti-diarrheal agent. This study aimed to evaluate the effect of A. arborescens Mill. on a Rattus norvegicus var. albinus-induced breast cancer model. We collected A. arborescens from the province of Julcán, La Libertad Region, Per, and prepared an ethanolic extract using pulverized leaves macerated in 96° ethanol for 72 h with magnetic stirring. In the evaluation of anticancer activity, four experimental groups with 10 female rats each were formed: Group I (Control-7,12-dimethylbenz[a]anthracene [DMBA]), which received DMBA (single dose) and physiological saline solution for 4 months, and Groups II, III, and IV, which received DMBA (single dose) and 200, 400, and 600 mg/kg/day of the ethanolic extract of A. arborescens, respectively, for 4 months. The DMBA control group presented histological characteristics of ductal carcinoma in situ with necrotic and inflammatory areas, whereas the A. arborescens extract group showed a decrease in tumor volume and recovery of the ductal duct. Ethanol extract of A. arborescens leaves decreases tumor development in rats with induced breast cancer, and this effect is dose-dependent.

A Review of Preclinical Tools to Validate Anti-Diarrheal Agents.

Since their inception, preclinical experimental models have played an important role in investigating and characterizing disease pathogenesis. These in vivo, ex vivo, and in vitro preclinical tests also aid in identifying targets, evaluating potential therapeutic drugs, and validating treatment protocols. Diarrhea is a leading cause of mortality and morbidity, particularly among children in developing countries, and it represents a huge health-care challenge on a global scale. Due to its chronic manifestations, alternative anti-diarrheal medications must be tested and developed because of the undesirable side effects of currently existing anti-diarrheal drugs. Several online databases, including Science Direct, PubMed, Web of Science, Google Scholar and Scopus, were used in the literature search. The datasets were searched for entries of studies up to May, 2022. The exhaustive literature study provides a large number of in vivo, in vitro and ex vivo models, which have been used for evaluating the mechanism of the anti-diarrheal effect of drugs in chemically-, pathogen-, disease-induced animal models of diarrhea. The advances and challenges of each model were also addressed in this review. This review encompasses diverse strategies for screening drugs with anti-diarrheal effects and covers a wide range of pathophysiological and molecular mechanisms linked to diarrhea, with a particular emphasis on the challenges of evaluating and predictively validating these experimental models in preclinical studies. This could also help researchers find a new medicine to treat diabetes more effectively and with fewer adverse effects.
