SYNTHESIS AND ANTIPROLIFERATIVE ACTIVITY OF SALICYLIDENEHYDRAZONES BASED ON INDOLE-2(3)-CARBOXYLIC ACIDS

Abstract

A series of indole-2(3)-carboxylic acid hydrazones were synthesized and their antiproliferative activity was studied for the K562 leukemia, MCF7 breast adenocarcinoma, and HCT116 colon carcinoma cell lines and resistant HCT116p53KO subline in order to preliminary screen biological properties and to reveal the role of the aldehyde fragment and heterocycle in the ability of compounds to inhibit tumor growth. A number of derivatives have been identified that inhibit the growth of tumor cells in submicromolar concentrations, promising for further optimization and in-depth study of antitumor properties.
