Synthesis, Structural Investigations, DNA/BSA Interactions, Molecular Docking Studies, and Anticancer Activity of a New 1,4-Disubstituted 1,2,3-Triazole Derivative.

We report herein a new 1,2,3-triazole derivative, namely, 4-((1-(3,4-dichlorophenyl)-1-1,2,3-triazol-4-yl)methoxy)-2-hydroxybenzaldehyde, which was synthesized by copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC). The structure of the compound was analyzed using Fourier transform infrared spectroscopy (FTIR), H NMR, C NMR, UV-vis, and elemental analyses. Moreover, X-ray crystallography studies demonstrated that the compound adapted a monoclinic crystal system with the 2/ space group.

Mechanistic insight into impact of phosphorylation on the enzymatic steps of farnesyltransferase.

Farnesyltransferase (FTase) is a heterodimeric enzyme, which catalyzes covalent attachment of the farnesyl group to target proteins, thus coordinating their trafficking in the cell. FTase has been demonstrated to be highly expressed in cancer and neurological diseases; hence considered as a hot target for therapeutic purposes. However, due to the nonspecific inhibition, there has been only one inhibitor that could be translated into the clinic.

Dimethyl sulfoxide reduces the stability but enhances catalytic activity of the main SARS-CoV-2 protease 3CLpro.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for coronavirus disease 2019 (COVID-19), one of the most challenging global pandemics of the modern era. Potential treatment strategies against COVID-19 are yet to be devised. It is crucial that antivirals that interfere with the SARS-CoV-2 life cycle be identified and developed.

Inhibition of SARS-CoV-2 main protease: a repurposing study that targets the dimer interface of the protein.

Coronavirus disease-2019 (COVID-19) was firstly reported in Wuhan, China, towards the end of 2019, and emerged as a pandemic. The spread and lethality rates of the COVID-19 have ignited studies that focus on the development of therapeutics for either treatment or prophylaxis purposes. In parallel, drug repurposing studies have also come into prominence.

Design and synthesis of novel cylopentapyrazoles bearing 1,2,3-thiadiazole moiety as potent antifungal agents.

In drug-resistant phytopathogenic fungi, there has been extensive research on microbiological and antifungal drug development. In this study, a novel series of cylopentapyrazole bearing a 1,2,3-thiadiazole ring 2a-e were designed and synthesized according to the principle of combination of bioactive structures. Thus, we have employed a [3 + 2] cycloaddition with 4-methyl-[1,2,3] thiadiazole-5-carboxylic acid hydrazones 1a-e and cyclopentadiene ring.
