Cyanobacteria: Their Biological Activities and Interesting Medical Applications: Review

Cyanobacteria possess secondary metabolites that can be used in the field of medicine through biotechnological applications. Recently, these microorganisms have gained more interest from scientists due to the production of bioactive compounds with applications in commercial and medical domains. Also, Cyanobacteria are a distinct class of oxygenic photosynthetic bacteria that live in a variety of settings around the globe. Many bioactive molecules derived from cyanobacteria exhibit a broad spectrum of activities, including antimicrobial, antibacterial, antiviral, antiinflammatory, antitumor, antimalarial, immunosuppressive, and anti-HIV (Human Immunodeficiency Virus) activities as well as protease inhibition, demonstrating their potential as a good source of new therapeutic lead compounds over the past two decades. Cyanobacteria are advantageous as a microbial source for drug development since they are easier to culture than other microorganisms and need only basic inorganic ingredients for growth. So, it appears that there is room for greater use of cyanobacteria in the drug development process. In addition, because of the wide variety of microbes present, cyanobacterial secondary metabolites may be a rich source of novel substances that can be used to create novel medications. However, a variety of problems with how the cyanophycean species are handled have made it difficult to exploit these species. Now that the majority of these issues have been handled, cyanobacteria may be able to increase the range of natural products derived from microbes. In contrast to other microbial sources of natural products, cyanobacteria have historically received less attention. This, combined with the enormous chemical diversity and biological activities of their products, has made them appealing sources of novel drugs for use in a variety of therapeutic fields. As a result, cyanobacterial strains from still uncharted and harsh habitats can make for excellent candidates in interdisciplinary research on the medicinal potential of cyanobacteria.

In Silico Studies of Compounds Present in Azadirachta Indica (Neem) and Their Ability to Bind Hiv Integrase Protein

Azadirachta indica (Neem) is an evergreen tree that belongs to the Meliaceae family. It is native to the Indian subcontinent and grows worldwide. It is also known as the "village pharmacy" in India for its wide range of therapeutic and pharmacological properties. An in vitro study indicated that A. indica showed anti-HIV properties. However, the exact mechanism for the supposed anti-HIV properties remains unknown. This study aimed to construct an in-silico database of the compounds present in A. in-dica and propose a computational analysis of these compounds against HIV integrase. We performed a thorough literature search to gather relevant information on the plant compounds, including chemical structure, location within the plant, extraction method, and percent yield of each compound found in the plant. We took a comprehensive ap-proach to closely study the binding pockets of HIV integrase and performed molecular docking on A. indica compounds using Molecular Operating Envi-ronment. A deductive analysis of the docking energies of these compounds revealed thirty potential binders against HIV integrase proteins. We further validated these binders by comparing the ligand in-teractions to known inhibitors using Ligplot+, which identified the presence of numerous hydrogen bonds and hydrophobic interactions at the protein binding pocket. In conclusion, we propose an un-derlying binding potential for several A. indica compounds with HIV integrase, yielding a potential mechanism for the anti-HIV activity of A. indica.

Tigliane-Type Diterpene Esters from the Fruits of Shirakiopsis indica and Their Anti-HIV Activity.

Four new diterpene esters, shirakindicans A-D (1-4), along with eight related known diterpene esters (5-12), were isolated from the fruits of the Bangladeshi medicinal plant Shirakiopsis indica. The structures of 1-4 were elucidated by spectroscopic data analysis and electronic circular dichroism (ECD) calculations. Shirakindican A (1) was assigned as a tigliane-type diterpene ester possessing an unusual 6β-hydroxy-1,7-dien-3-one structure, while shirakindican B (2) exhibits a tiglia-1,5-dien-3,7-dione structure. The anti-HIV activities of the isolated diterpene esters were evaluated and showed significant activities for sapintoxins A (5) and D (11), with EC50 values of 0.0074 and 0.044 μM, respectively, and TI values of 1 100 and 5 290. Sapatoxin A (12) also exhibited anti-HIV activity with an EC50 value of 0.13 μM and a TI value of 161.

Hybrids of small CD4 mimics and gp41-related peptides as dual-target HIV entry inhibitors

Hybrid molecules containing small CD4 mimics and gp41-C-terminal heptad repeat (CHR)-related peptides have been developed. A YIR-821 derivative was adopted as a CD4 mimic, which inhibits the interaction of gp120 with CD4. SC-peptides, SC34 and SC22EK, were also used as CHR-related peptides, which inhibit the interaction between the N-terminal heptad repeat (NHR) and CHR and thereby membrane fusion. Therefore, these hybrid molecules have dual-targets of gp120 and gp41. In the synthesis of the hybrid molecules of CD4 mimic-SC-peptides with different lengths of linkers, two conjugating methods, Cu-catalyzed azide-alkyne cycloaddition and direct cysteine alkylation, were performed. The latter reaction caused simpler operation procedures and higher synthetic yields than the former. The synthesized hybrid molecules of CD4 mimic-SC22EK have significantly higher anti-HIV activity than each sole agent. The present data should be useful in the future design of anti-HIV agents as dual-target entry inhibitors.

Anti-hepatitis B virus activity of lithospermic acid, a polyphenol from Salvia miltiorrhiza, in vitro and in vivo by autophagy regulation

Ethnopharmacological relevanceSalvia miltiorrhiza (the roots of S. miltiorrhiza Bunge, Danshen in Chinese), a traditional Chinese medicine, has been clinically used to prevent and treat various diseases, such as cardiovascular and cerebrovascular diseases, diabetes, and hepatitis B, in China and some other Asian countries. Lithospermic acid (LA), a polyphenol derived from S. miltiorrhiza, has been reported to exhibit multiple pharmacological properties, such as anti-inflammatory, anti-HIV, and anti-carbon tetrachloride-induced liver injury activities. However, little is known about the anti-hepatitis B virus (HBV) activity of LA. Aim of the studyThe study was projected to investigate the anti-HBV activity of LA in vitro (HepG2.2.15 and pHBV1.3-transfected HepG2 cells) and in vivo (pAAV-HBV1.2 hydrodynamic injection [HBV-HDI] mice) and explore the potential mechanism as well. Materials and methodsHepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) contents were detected by ELISA kits. HBV DNA and hepatitis B core antigen (HBcAg) levels were evaluated by quantitative real-time polymerase chain reaction and immunohistochemistry assay, respectively. The proteins in autophagy process, lysosomal acidic function, and autophagy-related signaling pathways were examined by Western blot. Transmission electron microscopy was used to observe the number of autophagosomes and autolysosomes. Confocal microscopy was applied to analyze the autophagic flux and lysosomal acidification, using mCherry-enhanced green fluorescent protein (EGFP)-microtubule-associated protein light chain (LC)3 and lysosomal probes, respectively. ResultsLA exhibited anti-HBV activity by inhibiting HBV DNA replication in HepG2.2.15 and pHBV-transfected HepG2 cells in dose- and time-dependent manners and hampering HBsAg and HBeAg levels in HepG2.2.15 cells to a certain extent. LA reduced HBV DNA, HBsAg/HBeAg, and HBcAg levels in the serum/liver tissues of HBV-HDI C57BL/6 mice during the 3-week treatment and suppressed the withdrawal rebound of HBV DNA and HBsAg in the mice serum. LA increased LC3-II protein expression and the number of autolysosomes/autophagosomes and promoted the degradation of sequestosome 1(p62) protein in vitro and in vivo. LA enhanced the co-localization of LC3 protein with autolysosomes, further confirming the ability of LA to induce a complete autophagy. Knockdown of autophagy-related gene (Atg) 7 or 5 in vitro and administration of 3-methyladenine (an autophagic inhibitor) in vivo disabled the inhibitory efficacy of LA on HBV DNA replication, suggesting that the anti-HBV efficacy of LA depended on its ability of inducing autophagy. LA could enhance lysosomal acidification and improve the function of lysosomes by promoting the protein expression of lysosomal-associated membrane protein (LAMP)-1, LAMP-2, and mature cathepsin D, which may contribute to the autophagic induction of LA. LA inhibited the activation of AKT and mammalian target of rapamycin (mTOR) induced by HBV, which was reversed by IGF-1 (an agonist of the PI3K/AKT/mTOR signaling pathway), indicating that LA elicited autophagy through hampering the PI3K/AKT/mTOR signaling pathway. ConclusionWe revealed the anti-HBV activity and mechanism of LA in vitro and in vivo. This study facilitates a new understanding of the anti-HBV potent components of S. miltiorrhiza and sheds light on LA for further development as an active constituent or candidate used in the therapy against HBV infection.

The anti-HIV potential of imidazole, oxazole and thiazole hybrids: A mini-review

Human immunodeficiency virus (HIV) especially HIV-1 infection and its progression to acquired immune deficiency syndrome (AIDS) remains a significant global health challenge. The advent of the highly active antiretroviral therapy (HAART) has greatly extended the life expectancy of patients living with HIV, but it has become evident that long-term HAART will not eliminate the HIV reservoir and cure the infection. Moreover, the drug resistance and undesirable side effects hamper efficacious therapy, creating an urgent need to develop novel, more effective and less toxic anti-HIV therapeutics. Imidazole, oxazole and thiazole with two heteroatoms at meta-position of five-membered rings are fascinating structures and constitute an important class of heterocycles in drug discovery. Their derivatives could exert the anti-HIV activity through diverse mechanisms and possess promising antiviral activity against both drug-sensitive and drug-resistant HIV strains. This review summarizes the research progress made regarding the anti-HIV potential of imidazole, oxazole and thiazole hybrids, and the structure–activity relationships (SARs) are also discussed to facilitate further rational design of more effective candidates, covering articles published from 2012 to 2022.

An Overview on the Synthesis of Fused Pyridocoumarins with Biological Interest.

Pyridocoumarins are a class of synthetic and naturally occurring organic compounds with interesting biological activities. This review focuses on the synthetic strategies for the synthesis of pyridocoumarins and presents the biological properties of those compounds. The synthesis involves the formation of the pyridine ring, at first, from a coumarin derivative, such as aminocoumarins, hydroxycoumarins, or other coumarins. The formation of a pyranone moiety follows from an existing pyridine or piperidine or phenol derivative. For the above syntheses, [4 + 2] cycloaddition reactions, multi-component reactions (MCR), as well as metal-catalyzed reactions, are useful. Pyridocoumarins present anti-cancer, anti-HIV, antimalarial, analgesic, antidiabetic, antibacterial, antifungal, anti-inflammatory, and antioxidant activities.

Synthesis and Evaluation of Prodrugs of α-Carboxy Nucleoside Phosphonates.

A range of lipophilic prodrugs of α-carboxy nucleoside phosphonates, potent inhibitors of HIV-1 reverse transcriptase without requiring prior phosphorylation, were synthesized to evaluate their in vivo potency against HIV in cell culture. A series of prodrug derivatives bearing a free carboxylic acid where the phosphonate was masked with bispivaloyloxymethyl, diisopropyloxycarbonyloxymethyl, bisamidate, aryloxyphosphoramidate, hexadecyloxypropyl, CycloSal, and acycloxybenzyl moieties were synthesized, adapting existing methodologies for phosphonate protection to accommodate the adjacent carboxylic acid moiety. The prodrugs were assayed for anti-HIV activity in CEM cell cultures─the bispivaloyloxymethyl free acid monophosphonate prodrug exhibited some activity (inhibitory concentration-50 (IC50) 59 ± 17 μM), while the other prodrugs were inactive at 100 μM. A racemic bispivaloyloxymethyl methyl ester monophosphonate prodrug was also prepared to assess the suitability of the methyl ester as a carboxylic acid prodrug. This compound exhibited no activity against HIV in cellular assays.

Anti-HIV Ermiasolides from Croton megalocarpus.

In recent years, elucidation of novel anti-HIV bioactive compounds from natural products is gaining importance rapidly, not only from the research and publications, but also from controlled clinical studies. Here we report three new anti-HIV eudesmane-type sesquiterpenes, 5β-Hydroxy-8α-methoxy eudesm-7(11)-en-12,8-olide (1), 5β,8α-Dihydroxy eudesm-7(11)-en-12,8-olide (2) and 5β-Hydroxy-8H-β-eudesm-7(11)-en-12,8-olide (3). These are trivially named ermiasolide A-C and were isolated from the bark of Croton megalocarpus. 5β-Hydroxy-8α-methoxy eudesm-7(11)-en-12,8-olide (1), showed the highest anti-HIV activity by inhibiting 93% of the viral replication with an IC50 = 0.002 µg/mL. On the other hand, 5β-Hydroxy-8H-β-eudesm-7(11)-en-12,8-olide (3) and 5β,8α-dihydroxy eudesm-7(11)-en-12,8-olide (2), inhibited viral replication by 77.5% at IC50 = 0.04 µg/mL and 69.5% at IC50 = 0.002 µg/mL, respectively. Molecular docking studies showed that the proposed mechanism of action leading to these results is through the inhibition of HIV-protease.

Anti-HIV crotocascarin ω from Kenyan Croton dichogamus

An anti-HIV methanol-soluble fraction of a 1:1 CH2Cl2:CH3OH extract of twigs of a Kenyan Croton dichogamus yielded seven compounds, the new crotocascarin ω (1), the known β-oplopanone (2), dihydroconiferyl acetate (3), 3’(4’’-hydroxyphenyl)-propyl benzoate (4), lupeol, sitosterol and stigmasterol. Crotocascarin ω (90%) inhibited HIV-1 replication with an IC50 value of 5.3 nM, and the compound was cytotoxic towards MT-4 cells presenting an IC50 value of 84 µM. In silico modelling showed that the anti-HIV activity for compound 1 could be through the HIV-1 protease inhibition.

Unveiling a family of spiro-β-lactams with anti-HIV and antiplasmodial activity via phosphine-catalyzed [3+2] annulation of 6-alkylidene-penicillanates and allenoates.

The molecular architecture of spirocyclic compounds has been widely explored within the medicinal chemistry field to obtain new compounds with singular three-dimensional pharmacophoric features and improved bioactivity. Herein, the synthesis of 68 new spirocyclopentene-β-lactams is described, resulting from a rational drug design and structural modulation of a highly promising lead compound BSS-730A, previously identified as having dual antimicrobial activity associated with a novel mechanism of action. Among this diverse library of new compounds, 22 were identified as active against HIV-1, with eight displaying an IC50 lower than 50 nM. These eight compounds also showed nanomolar activity against HIV-2, and six of them displayed micromolar antiplasmodial activity against both the hepatic and the blood stages of infection by malaria parasites, in agreement with the lead molecule’s bioactivity profile. The spirocyclopentene-β-lactams screened also showed low cytotoxicity against TZM-bl and Huh7 human cell lines. Overall, a family of new spirocyclopentene penicillanates with potent activity against HIV and/or Plasmodium was identified. The present structure–activity relationship open avenues for further development of spirocyclopentene-β-lactams as multivalent, highly active broad spectrum antimicrobial agents.

Recent Advances in Synthesis and Anticancer Potential of Triazole-Containing Scaffolds.

Cancer is the most lethal disease that may be found anywhere globally. Approximately 10% of individuals die due to cancer of various types, with 19.3 million new cancer cases and 10 million deaths reported in 2020. More than 100 medications are commercially available for the treatment of cancer, but only a few candidates have high specificity, resulting in several side effects. The scientific community has spent the past decades focusing on drug discovery. Natural resources are used to isolate pharmaceutically active candidates, which are then synthesized in laboratories. More than 60% of all prescribed drugs are made from natural ingredients. Unique five-membered heteroaromatic center motifs with sulfur, oxygen and nitrogen atoms are found in heterocyclic compounds, such as indazole, thiazole, triazole, triazole, and oxazole, and are used as a core scaffold in many medicinally important therapies. Triazole possesses a wide range of pharmacological activities, including anticancer, antibacterial, antifungal, antibiotic, antiviral, analgesic, anti-inflammatory, anti-HIV, antidiabetic, and antiprotozoal activities. Novel triazole motifs with a variety of biological characteristics have been successfully synthesized using versatile synthetic methods. We intend here to facilitate the rational design and development of innovative triazole-based anti-cancer medicines with increased selectivity for various cancer cell lines by providing insight into various ligand-receptor interactions.

Google Scholar, Pubmed, and SciFinder were searched databases with ''pyrazol'' keywords. Further, the year of publication and keywords ''Anti-HIV'' filter was applied to obtain relevant reported literature for anti-HIV agents containing pyrazole as a core or substituted derivatives. This review article has shown the comprehensive compilation of 220 compounds containing pyrazole nucleus and possessing anti-HIV activity by sorting approximately 40 research articles from 2001 to date. 1-(4-Benzoylpiperazin-1-yl)-2-(4-fluoro-7-(1H-pyrazol-3-yl)-1H-pyrrolo[2,3-c]pyridin- 3-yl)ethane-1,2-dione (13), 3-(3-(2-(4-benzoylpiperazin-1-yl)-2-oxoacetyl)-4-fluoro-1H-pyrrolo[2,3- c]pyridin-7-yl)-1H-pyrazole-5-carboxamide (31), 3-(3-(2-(4-benzoylpiperazin-1-yl)-2-oxoacetyl)-4- fluoro-1H-pyrrolo[2,3-c]pyridin-7-yl)-1H-pyrazole-5-carboxamide (88), 3-cyanophenoxypyrazole derivative (130), and 4-(4-chlorophenyl)-5-(4-methyl-5-((4-nitrophenyl)diazenyl)thiazol-2-yl)-3- phenyl-5,6-dihydro-4H-pyrazolo[4,3-d]isoxazole (178) were the most potent mono-, di-, tri-, tetrasubstituted, and fused pyrazole derivatives, respectively, which have shown potent anti-HIV activity among all the described derivatives as compared with standard anti-HIV drugs. This review article provides an overview of the potential therapeutic activity of pyrazole derivatives against HIV that will be helpful for designing pyrazole containing compounds for anti-HIV activity.

Anti-HIV Macrocyclic Daphnane Orthoesters with an Unusual Macrocyclic Ring from Edgeworthia chrysantha.

Edgeworthianins A-E (1-5) were isolated from Edgeworthia chrysantha as a class of macrocyclic daphnane orthoesters with an unusual macrocyclic ring formed from a C14 aliphatic chain. Their structures were elucidated by extensive physicochemical and spectroscopic analyses. Compounds 2, 4, and 5 exhibited potent anti-HIV activity against HIV-1 infection of MT4 cells with EC50 values of 29.3, 8.4, and 2.9 nM, respectively. These compounds broaden the findings of the structure-activity relationship of macrocyclic daphnane orthoesters for further anti-HIV drug development.

Appraisal of antiretroviral herbal medicines with proven efficacy: modulation of drug-metabolizing enzymes and permeability glycoprotein activities

Human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) constitutes a source of great concern to health authorities worldwide. Herbal medicinal products are used as a significant treatment option for highly active antiretroviral therapies, the efficacies of which are negatively impacted by the emergence of multidrug-resistant strains to the recommended treatment guidelines. This review provides an updated synopsis of available documents on herbal medicinal products with anti-HIV activities. Concurrent consumption of herbal products with conventional drugs, which is often necessitated by co-morbidity of HIV with other diseases, can potentially alter the pharmacokinetics of the co-administered orthodox drugs. Phytochemical constituents of the herbal medicinal products with antiretroviral activities were identified, and their potential to mediate pharmacokinetic changes through modulation of drug-metabolizing enzymes and P-glycoprotein was reported. Herb-drug interactions (HDIs) that can result in significant adverse effects were also discussed with documenting the information for the therapeutic utility of these clinically effective antiretroviral herbal medicinal products with potential for development into newer anti-HIV drugs.

Investigations on the twigs and leaves of Antirhea chinensis have led to the discovery of two undescribed pentacyclic triterpenoids (1 and 2) and nine known analogs. Compounds 1 and 2, each assigned as the ursane and 24-noroleanane-type triterpenoids, featuring similar oxidation pattern of 3β,6β,19α-trihydroxy-28-carboxyl. Their structures were elucidated via comprehensive analyses of spectroscopic data. Compound 1 displayed potent anti-HIV activity (EC50 =1.24 μM) and high selectivity index (SI >32.3).

Design, Synthesis and Structure-Activity Relationships of Phenylalanine-Containing Peptidomimetics as Novel HIV-1 Capsid Binders Based on Ugi Four-Component Reaction.

As a key structural protein, HIV capsid (CA) protein plays multiple roles in the HIV life cycle, and is considered a promising target for anti-HIV treatment. Based on the structural information of CA modulator PF-74 bound to HIV-1 CA hexamer, 18 novel phenylalanine derivatives were synthesized via the Ugi four-component reaction. In vitro anti-HIV activity assays showed that most compounds exhibited low-micromolar-inhibitory potency against HIV. Among them, compound I-19 exhibited the best anti-HIV-1 activity (EC50 = 2.53 ± 0.84 μM, CC50 = 107.61 ± 27.43 μM). In addition, I-14 displayed excellent HIV-2 inhibitory activity (EC50 = 2.30 ± 0.11 μM, CC50 > 189.32 μM) with relatively low cytotoxicity, being more potent than that of the approved drug nevirapine (EC50 > 15.02 μM, CC50 > 15.2 μM). Additionally, surface plasmon resonance (SPR) binding assays demonstrated direct binding to the HIV CA protein. Moreover, molecular docking and molecular dynamics simulations provided additional information on the binding mode of I-19 to HIV-1 CA. In summary, we further explored the structure—activity relationships (SARs) and selectivity of anti-HIV-1/HIV-2 of PF-74 derivatives, which is conducive to discovering efficient anti-HIV drugs.
