Synthesis, in vitro and in vivo evaluation of novel substituted N-(4-(2-(4-benzylpiperazin-1-yl)ethoxy)phenyl)-N-methyl-quinazolin-4-amines as potent antitumor agents

Bioorg Med Chem Lett. 2016 Apr 15;26(8):1931-5. doi: 10.1016/j.bmcl.2016.03.016. Epub 2016 Mar 7.

Abstract

A novel series of substituted N-(4-(2-(4-benzylpiperazin-1-yl)ethoxy)phenyl)-N-methylquinazolin-4-amines were synthesized and evaluated for their in vitro antiproliferative activity. Among them, compound 7a exhibited the best potency, with IC50 values of 0.029-0.147 μM against four types of cancer cell lines. In addition, 7a was confirmed that it could arrest the cell cycle at G2/M phase and trigger apoptosis. Indirect immunofluorescence staining revealed its anti-tubulin property. Importantly, 7a significantly inhibited tumor growths in HepG2 xenograft models without causing significant loss of body weight, suggesting that 7a is a promising new anticancer agent to be developed.

Keywords: 4-Anilinoquinazoline derivatives; Anti-proliferation; G(2)/M arrest.
