New Hydrazone Derivatives Featuring Isatin and Piperazine Moieties: Synthesis, Cytotoxicity Evaluation, and Molecular Modeling Studies

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT In this study, ten novel compounds (IPH1–IPH10) were designed by integrating three pharmacophores (isatin, piperazine, and hydrazone) commonly found in the molecular structures of anticancer agents. The target molecules were obtained by the reaction of in‐house prepared 4‐(4‐(pyridin/pyrimidin‐2‐yl)piperazin‐1‐yl)benzohydrazide with various ...
