Investigating the Antiproliferative Activity of Novel 4‐Chloro‐8‐Nitro‐1,2‐Dihydro‐3‐Quinoline Acylhydrazones on Human Cervical Cancer Cell Lines

A new series of acyl hydrazones have been synthesized from 4-chloro-8-nitro-1,2-dihydroquinoline-3-carbaldehyde. These compounds were characterized using various spectroscopic techniques. Density functional theoretical (DFT) studies were conducted to understand the correlation between electronic parameters and biological activity. The biological activity of the compounds was theoretically examined through molecular docking and ADMET (Absorption, Distribution, Metabolism, Excretion, and Toxicity) analysis. The compounds demonstrated high absorption rates and were found to be non-hepatotoxic. Preliminary cytotoxicity screenings against HeLa cell lines identified compound 7 as the most potent, with an IC₅₀ value of 18.8 μM. This compound was further selected for bioimaging studies. The results indicate that compound 7 induces apoptosis at its IC₅₀ concentration, suggesting its potential as an anticancer agent.
