Antifungal screening and in silico mechanistic studies of an in-house azole library
Authors:
Publisher and Date:(2019)Systemic Candida infections pose a serious public health problem with high morbidity and mortality. C. albicans is the major pathogen identified in candidiasis; however, non-albicans Candida spp. with antifungal resistance are now more prevalent. Azoles are first-choice antifungal drugs for candidiasis; however, they are ineffective for certain infections caused by the resistant strains. Azoles block ergosterol synthesis by inhibiting fungal CYP51, which leads to disruption of fungal membrane ...

Discovery of new azoles with potent activity against Candida spp. and Candida albicans biofilms through virtual screening
Authors:
Publisher and Date:(Elsevier, 2020)Systemic candidiasis is a rampant bloodstream infection ofCandidaspp. andC. albicansis the majorpathogen isolated from infected humans. Azoles, the most common class of antifungals which sufferfrom increasing resistance, and especially intrinsically resistant non-albicans Candida(NAC) species, actby inhibiting fungal lanosterol 14a-demethylase (CYP51). In this study we identified a number of azolecompounds in 1-(2,4-dichlorophenyl)-2-(1H-imidazol-1-yl)ethanol/ethanone oxime ester structurethrough ...

Structural studies of nmda receptor and xanthine oxidase enzyme
Authors:
Publisher and Date:(Kadir Has University, 2019)The first part of the thesis deals with the structural studies of N-Methyl-D-Aspartate receptors (NMDARs). NMDARs are ionotropic ligand-gated receptors that have pivotal roles at the central neuronal system but hyperactivity of NMDARs could contribute to neurodegenerative diseases. Therefore understanding the activation mechanism of NMDARs is important as it may lead to the development of new treatments for neurodegenerative diseases. in this thesis human GluN1/GluN2A type NMDAR is modeled based ...

Synthesis, biological evaluation and molecular docking studies of bis-chalcone derivatives as xanthine oxidase inhibitors and anticancer agents
Authors:
Publisher and Date:(Elsevier, 2019)In this study, a series of B-ring fluoro substituted bis-chalcone derivatives were synthesized by Claisen-Schmidt condensation reactions and evaluated for their ability to inhibit xanthine oxidase (XO) and growth inhibitory activity against MCF-7 and Caco-2 human cancer cell lines, in vitro. According to the results obtained, the bis-chalcone with fluoro group at the 2 (4b) or 2,5-position (4g) of B-ring were found to be potent inhibitors of the enzyme with IC50 values in the low micromolar range. ...
