Bioorg Med Chem Lett. 2013 May 1;23(9):2683-7. doi: 10.1016/j.bmcl.2013.02.082. Epub 2013 Feb 27.

Abstract

Starting from pyrazole HTS hit (1), a series of 1-aryl-1H-indazoles have been synthesized as JNK3 inhibitors with moderate selectivity against JNK1. SAR studies led to the synthesis of 5r as double digital nanomolar JNK3 inhibitor with good in vivo exposure.
