Synthesis and biological activity of new 2,4,6-trisubstituted triazines as potential phosphoinositide 3-kinase inhibitors

Abstract

Twenty-five novel 2,4,6-trisubstituted triazines were synthesized and biologically evaluated. Most of the compounds synthesized showed good antiproliferative activity against HCT-116 and MCF-7. Compounds B18 and B19 showed the best antiproliferative activity. Further study showed B18 and B19 inhibited four phosphoinositide 3-kinase isoforms and mammalian target of rapamycin with good potency. These results demonstrate that 2,4,6-trisubstituted triazines are potentially useful phosphoinositide 3-kinase inhibitors for the development of new anticancer drugs.
