Background: Tuberculosis is global health threat caused by infectious bacillus called Mycobacterium tuberculosis. To develop newer antitubercular agents against bacterial resistance, we have designed new quinoline derivatives 6a-6f and 7a-7f by molecular hybridization approach and evaluated for antitubercular, antioxidant and cytotoxicity studies along with molecular docking study. Methods: The designed molecules Read More

Background: Dyslipidemia is a serious threat to human health. The objective of our research was to develop effective FXR antagonists against dyslipidemia. Methods: Herein we describe the design, synthesis of 37 N-(5-(2,5-dimethylphenoxy)-2,2- dimethylpentyl)-benzamide derivatives and evaluated for their FXR inhibition ability compared to GS and SIPI-7623. Results: Structure–activity relationship analyses indicated that co Read More

Background: Drug resistance and reservoirs of latent viral infection have prevented total eradication of the HIV-virus which underlines the need for continuous efforts in the discovery of new anti-HIV agents. The present study deals with the synthesis of novel compounds based on naturally occurring scaffolds and their evaluation as potential anti-HIV agents. Objective: Design and synthesis of styrylquinoline scaffold based ne Read More

Background: Ester and amide derivatives of shikonin were synthesized to improve the chemical stability of shikonin. Methods: All synthesized compounds were evaluated for their antiproliferative activity against A549 cell line by SRB assay, and five of them demonstrated comparable cytotoxicity to shikonin. Results and Conclusion: The most potent compound, 22d, was more stable and potent than shikonin.

Background: Aedes aegypti is the main mosquito vector for the transmission of several serious diseases, including Japanese encephalitis, yellow fever, Zika, and dengue virus. Increasing resistance to the limited number of public health chemicals requires the evaluation of new chemicals as potential control products. Methods: Pyrimidine-based compounds have shown some efficacy for agricultural uses and as mosquitocidal Read More

Background: Due to high demand of developing new compounds to solve the health issues, paracetamol resembling 4-acetamidobenzaldehyde was derivatized into different new compounds including important pharmacophores (benzimidazole, benzothiazole). The synthesized compounds were investigated for anti-Alzheimer, antioxidant and DNA binding abilities. Methods: The new compounds were synthesized by the well-establ Read More

Objects: Three compounds, 2-phenyl-2,3-dihydrochromen-4-one (1), 2-4-(benzyloxy-3- methoxyphenyl)-2-3-dihydrochromen-4-one (2), basilmoside 24-ethyl-25-methylcholesta-5,22- dien-3-β-O-D-glucoside (3) along with Compound 4 formed by the acetylation of Compound 3 from Ocimum basilicum were isolated and structures were elucidated through spectroscopic methods including EI-Mass, 1D and 2D NMR followed by bi Read More

Background: Mitotic kinesin Eg5, a member of the kinesin superfamily, plays an essential role in cell proliferation while the regulated cell proliferation is essential for survival, but uncontrolled cell proliferation increases the risk of cancer. Therefore development of new efficient Eg5 inhibitors is very important in cancer chemotherapy. S-trityl-L-cysteine (STLC) and their analogues are known as potent allosteric inhibito Read More

Background: Dipeptides and their analogs have multiple biological functions, such as bitter taste, angiotensin-converting enzyme (ACE) inhibition, etc. That design and modification of dipeptides guided by theoretical models are of great significance for research and development on drug, especially in discovery and optimization of lead compound, which can reduce the experimental expenditure and improve the hit rate. M Read More

Background: Epigenetics has proven to be a missing link to understand different diseases. However, the full understanding of chemical modifications of histones is still challenging. Initial research was focused on the ‘editing’ (writing/erasing) processes in the epigenome. More recently, the modulation of ‘reader’ enzymes has shown therapeutic potential. Bromodomains and Extra Terminal domain (BET) proteins Read More

Background: Sulfur Mustard (SM), a chemical agent that is fat soluble with garlic-like or mustard odor and it needs moisture for activation. The mustard agent has alkylating, blistering and vesicating properties. Various cellular and molecular mechanisms of different signaling pathways are responsible for these acute and delayed cutaneous complications in the SM-exposed victims. The aim of this study is to review these me Read More
