"Synthesis and characterization of a novel pyridinium iodide-tagged Schiff base and its metal complexes as potential ACHN inhibitors".

In quest of developing an efficient and effective drug against the ACHN human renal adenocarcinoma cell line herein, we report the synthesis and characterization of a novel Pyridinium iodide-tagged Schiff base (5) and its Cu (II)/Zn (II)/Cd (II)-complexes (6). The synthesized compounds are well characterized by Elemental analysis, UV-Visible, FTIR, Magnetic Susceptibility, NMR, HRMS, MALDI, and PXRD techniques. They were then subsequently tested on the ACHN cell lines using MTT assays and their IC values were determined, followed by their ROS production capacity.

Exploration of inhibitory action of Azo imidazole derivatives against COVID-19 main protease (M): A computational study.

Four novel ionic liquid tagged azo-azomethine derivatives (L1-L4) have been prepared by the condensation reaction of azo-coupled ortho-vaniline precursor with amino functionalised imidazole derivative and the synthesized derivatives (L1-L4) have been characterized by different analytical and spectroscopic techniques. Molecular docking studies were carried out to ascertain the inhibitory action of studied ligands (L1-L4) against the Main Protease (6LU7) of novel coronavisrus (COVID-19). The result of the docking of L1-L4 showed a significant inhibitory action against the Main protease (M) of SARS-CoV-2 and the binding energy (ΔG) values of the ligands (L1-L4) against the protein 6LU7 have found to be -7.
