in multiple studies, synthesis and biologicalevaluation of promising 17β-HSD2 inhibitors have been reported. Our previous work led to the identification of phenylbenzenesulfonamides and -sulfonates as new 17β-HSD2 inhibitors by ligand-based pharmacophore modeling and virtual screening. In this study, new molecules representing this scaffold were synthesized and tested in vitro for their 17β-HSD2 activity
An electrochemical method for the synthesis of N-substituted 2-aminobenzimidazoles through a NaI-mediated desulfurization–cyclization process is reported. This electrosynthesis method utilizes cost-effective NaI as both a mediator and an electrolyte in a catalytic amount (0.2 equiv), replacing traditional oxidizing reagents. N-Substituted o-phenylenediamines and isothiocyanates undergo a thiourea
