Green synthesis, molecular docking and anticancer activity of novel 1,4-dihydropyridine-3,5-Dicarbohydrazones under grind-stone chemistry

Abstract

The reaction of 2,6-dimethyl-4-phenyl-1,4-dihydropyridine-3,5-dicarbohydrazide with variety of carbonyl compounds such as substituted benzaldehydes, cycloalkanones and hetero-cyclic ketones under grinding method under catalyst- and solvent-free conditions at room temperature, in the presence of catalytic drops of acetic acid gave a new series of 2,6-dimethyl-4-phenyl-1,4-dihydropyridine-3,5-dicarbohydrazone derivatives in good to excellent yields. The structures of new products were elucidated on the basis of their spectral data and elemental analysis. Most of the newly prepared compounds were evaluated towards HepG2 cell lines and showed good IC50 for some compounds. Additionally, molecular docking of the novel chemical entities using Autodock Vina demonstrated their binding modes within the active site of DYRK1A.
