"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 IC50 values were determined, followed by their ROS production capacity. Among the tested compounds Zn (II)-complex 6(b) was found to be the most potent one with a minimum IC50 value while the ligand (5) was the least.
