Design, synthesis and biological evaluation of aryl amino derivatives of pyrido [3,2-d]pyrimidines as anticancer agents

Abstract

A new bunch of substituted aryl amino derivatives structurally modified pyrido[3,2-d]pyrimidines (10a–j) have been synthesized and evaluated for anticancer effects against PC3 (human prostate), A549 (human lung), MCF-7 (human breast) and Colo-205 (human colon) cancer cell lines by utilizing of MTT procedure. Most of the synthesized compounds were showed anticancer activity good to moderate activities with IC50 values range from 0.013 ± 0.0058 µM to 8.22 ± 5.87 µM, whereas, standard 9 etoposide used as standard drug) showed IC50 values from 0.14 ± 0.017 µM to 3.08 ± 0.135 µM, respectively. Among the synthesized compounds, five compounds 10a, 10b, 10c, 10d and 10e demonstrated more potent activity on all cell lines. Mainly, compound 10e displayed higher anticancer activity.
