Synthesis, Structural Characterization and Cancer Cell Cytotoxic Activity of Vadimezan Hydrazones

Resumo

New vadimezan hydrazones were synthesized as E/Z isomers and characterized by IR, 1H NMR, MS, and HRMS techniques; the ratio of isomers was analyzed by NOESY spectra. All compounds were evaluated for their cytotoxic activities against endometrial Ishikawa, lung A549 and NCI-460, chorion Bewo, cervical HeLa and Siha, breast MCF-7, leukemia HL-60, liver BEL-7402, and stomach BGC-823 cancer cell lines in vitro by standard MTT assay. The preliminary pharmacological results indicated that compound 5c exhibited most promising cytotoxic activity against NCI-460 cell line with IC₅₀ value of 7.01 ± 0.53 μM.
