RESUMO

Heterocyclic molecules have fascinated a massive interest in medicinal chemistry. They are heterocyclic compounds that have gained significance due to their diverse variety of pharmacological activities. Benzimidazole is a heterocyclic compound consisting of benzene and imidazole rings. The ease of synthesis and the structural versatility of benzimidazole make it a promising scaffold for drug development. Many biological actions of benzimidazole derivatives have been well documented, including antibacterial, antiviral, anticancer, anti-inflammatory, antitubercular, and anthelmintic properties. The mechanism of action of benzimidazole derivatives varies with their chemical structure and target enzyme. This review has explored numerous methods for producing benzimidazole derivatives as well as a broad range of pharmacological activities. SAR investigations are also discussed in this review as they provide crucial details regarding the essential structural qualities that benzimidazole derivatives must have in order to be biologically active, which could aid in the rational design of new drug candidates. Benzimidazole scaffold is an exclusive structure in drug design and discovery. Many new pharmaceutical drugs containing benzimidazole are anticipated to be available within the next ten years as a result of the extensive therapeutic applications of benzimidazole and its derivatives. This review inspired many researchers to develop more biologically active compounds bearing benzimidazole, expanding the scope of finding a remedy for other diseases. From this study, we concluded that 2-substituted benzimidazole was considered more extensively by researchers.

RESUMO

Alzheimer's disease (AD) is a debilitating form of dementia that primarily affects cholinergic neurons in the brain, significantly reducing an individual's capacity for learning and creative skills and ultimately resulting in an inability to carry out even basic daily tasks. As the elderly population is exponentially increasing, the disease has become a significant concern for society. Therefore, neuroprotective substances have garnered considerable interest in addressing this universal issue. Studies have shown that oxidative damage to neurons contributes to the pathophysiological processes underlying AD progression. In AD, tau phosphorylation and glutamate excitotoxicity may play essential roles, but no permanent cure for AD is available. The existing therapies only manage the early symptoms of AD and often come with numerous side effects and toxicities. To address these challenges, researchers have turned to nature and explored various sources such as plants, animals, and marine organisms. Many historic holy books from different cultures emphasize that adding marine compounds to the regular diet enhances brain function and mitigates its decline. Consequently, researchers have devoted significant time to identifying potentially active neuroprotective substances from marine sources. Marine-derived compounds are gaining recognition due to their abundant supply of diverse chemical compounds with biological and pharmacological potential and unique mechanisms of action. Several studies have reported that plants exhibit multitarget potential in treating AD. In light of this, the current study focuses on marine-derived components with excellent potential for treating this neurodegenerative disease.

RESUMO

BACKGROUND: A Liposomal delivery system is a novel and distinguishing way of organized medicine administration. The advancements in liposomal technology allow for controlled drug distribution to treat rheumatoid arthritis effectively. Liposomes are microscopic lipid-based vesicles that have shown promise in transporting substances, such as superoxide dismutase, hemoglobin, erythrocyte interleukin-2, gamma interferon, and smaller compounds. OBJECTIVE: Liposomes are biocompatible, nontoxic, biodegradable, non-immunogenic, and flexible, with sizes ranging from 0.025 to 2.5 micrometers. LDS is normally employed to distribute drugs through topical conduits, but fresh investigation has shown that it offers promise for oral, ocular, and parenteral administration. Our major objective is to gather information about liposomes, focusing on their applicability in rheumatoid arthritis treatment. METHODS: In the current review, we have tried to cover the preparation techniques, clinical trials, patents, marketed formulations, vesicle types, formulations used to treat rheumatoid arthritis and other ailments, and layered liposomal formulations with improved characteristics. CONCLUSION: Research has established LDS as a biocompatible, sustainable, non-toxic, adaptable material. Researchers working on LDS technology in rheumatoid arthritis will find this review particularly useful as it may unclutter novel ways for therapeutic intercessions in treating the disease.

RESUMO

Purpose: Small molecule glucokinase (GK) modulators not only decrease fasting and basal plasma sugar contents but also progress glucose tolerance. The hydro-ethanolic extract of the Persian shallot (Allium hirtifolium Boiss.) decreased blood glucose, improved plasma insulin and amplified GK action. The present study was proposed to screen phytoconstituents from Persian shallot as human GK activators using in silico docking studies. Methods: A total of 91 phytoconstituents reported in Persian shallot (A. hirtifolium Boiss.) were assessed in silico for the prediction of drug-like properties and molecular docking investigations were carried out with human GK using AutoDock vina with the aim of exploring the binding interactions between the phytoconstituents and GK enzyme followed by in silico prediction of toxicity. Results: Almost all the phytoconstituents tested showed good pharmacokinetic parameters for oral bioavailability and drug-likeness. In the docking analysis, cinnamic acid, methyl 3,4,5-trimethoxy benzoate, quercetin, kaempferol, kaempferol 3-O-ß-D-glucopyranosyl-(1- > 4)-glucopyranoside, 5-hydroxy-methyl furfural, ethyl N-(O-anisyl) formimidate, 2-pyridinethione and ascorbic acid showed appreciable hydrogen bond and hydrophobic type interactions with the allosteric site residues of the GK enzyme. Conclusion: These screened phytoconstituents may serve as promising hit molecules for further development of clinically beneficial and safe allosteric activators of the human GK enzyme.
