Thieno[3,2-c]pyrazoles: a novel class of Aurora inhibitors with favorable antitumor activity

Bioorg Med Chem. 2010 Oct 1;18(19):7113-20. doi: 10.1016/j.bmc.2010.07.048. Epub 2010 Jul 25.

Abstract

A novel series of 3-amino-1H-thieno[3,2-c]pyrazole derivatives demonstrating high potency in inhibiting Aurora kinases was developed. Here we describe the synthesis and a preliminary structure-activity relationship, which led to the discovery of a representative compound (38), which showed low nanomolar inhibitory activity in the anti-proliferation assay and was able to block the cell cycle in HCT-116 cell line. This compound demonstrated favorable pharmacokinetic properties and good efficacy in the HL-60 xenograft tumor model.
