Synthesis and biological evaluation of 4-aryl-5-cyano-2H-1,2,3-triazoles as inhibitor of HER2 tyrosine kinase.

Abstract

4-Aryl-5-cyano-2H-1,2,3-triazoles bearing a variety of substituting groups on 4-phenyl were synthesized. The chemicals, designed as HER2 tyrosine kinase inhibitors, were screened for bioactivity of inhibiting growth of breast cancer MDA-MB-453 cells. The lowest IC(50) value of inhibiting HER2 tyrosine kinase phosphorylation in breast cancer cells is 6.6microM and the IC(50) value of cell growth inhibition is correspondingly 30.9microM. The lipophilicity of substituting groups on triazoles is the main factor to influence their bioactivities.
