Design, synthesis and anti-cancer evaluation of a novel series of pyrazolo [1, 5-a] pyrimidine substituted diamide derivatives

Abstract

A novel series of pyrazolo [1, 5-a] pyrimidine substituted diamides has been designed and synthesized using a linear mode multistep synthesis. The synthesized compounds were characterized by 1H NMR, 13C NMR, ESI-MS and IR analyses. These new compounds were screened for their in vitro antiproliferative activity using an MTT assay. Out of 23 derivatives synthesized in the current study, compounds 10q, 10u and 10w showed good anticancer activity against HeLa cell line. Furthermore, these derivatives gave IC50 values of less than 10 µM against HeLa cell and were therefore more potent than the marketed anticancer drug cis-platin (17.83 µM).
