Synthesis of New Hydrazone Derivatives and Evaluation of their Efficacy as Proliferation Inhibitors in Human Cancer Cells

Abstract

Background: Hydrazine-hydrazones represent a group of bioactive compounds that display antibacterial, anti-inflammatory, antiviral or anticancer activities.

Objective: In this study, we designed new derivative compounds from groups of hydrazones.

Methods: The group of new derivatives was evaluated by the viability assay in human cancer and normal cells.

Results: The dimethylpyridine hydrazones showed potent inhibition of cell proliferation of breast, colon cancer cells, human melanoma and glioblastoma. Compound 12 inhibited proliferation of cancer cells exhibiting a drug-resistant phenotype (MCF-7/DX and LoVoDX) at low millimolar concentrations. Whereas, antimelanoma activity was revealed by Compounds 2, 4, 7 and 12.

Conclusion: The present results highlighted newly synthetized hydrazine derivatives an excellent base for the design of new anticancer agents and resistance inhibitors.
