Synthesis and Cytotoxicity of Novel Diaryl Ureas Containing 2-Amino-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidinyl Group

Abstract

Abstract:

A series of 2-amino-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidinyl substituted diaryl urea derivatives was designed and synthesized. Their in vitro cytotoxicities against two cancer cell lines(Bel-7402 and A549) were evaluated by standard MTT assay. Six of tested compounds 6, 8, 10, 17, 21 and 22 exhibited more potent cytotoxicity superior to sorafenib. The structure activity relationship(SAR) study indicates that 2-amino-5,6,7,8-tetrahydropyrido- [4,3-d]pyrimidinyl group was an option for cytotoxic potency.

Key words: Diaryl urea, 2-Amino-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine, Cytotoxicity
