A New Series of Indole and Azaindole Derivatives with Oxo-dihydropyridines: Synthesis, Characterization and Cytotoxicity Studies against Breast Malignant Cell Lines

In this investigation, a novel series of indole and azaindole comprising oxo-dihydropyridine derivatives was synthesized. From their spectral (1H NMR and FTIR) as well as elemental (MS) investigations, the structures of all the synthesized 12 oxo-dihydropyridine derivatives were determined. Cytotoxicity of synthesized twelve compound was evaluated against MDA-MB-231 malignant breast cells had been assessed. Compound 1,6-diamino-4-(1H-indol-3-yl)-2-oxo-1,2-dihydropyridine-3,5-dicarbonitrile showed more percent of inhibition of growth and four more derivatives showed moderate percent of inhibition of growth counter to MDA-MB-231 malignant breast cells. The derivative 1,6-diamino-4-(1H-indol-3-yl)-2-oxo-1,2-dihydropyridine-3,5-dicarbonitrile showed the highest effectiveness when assessing the IC50 value against the malignant breast cell line MDA-MB-231. Each of the compounds synthesized has a druggable character and meets Lipinski’s criteria of five.
