Biochem/physiol Actions

LY-364947 is a selective, ATP-competitive inhibitor of Transforming Growth Factor-β Type I receptor kinase (TGF-β RI, ALK5) with IC50 = 59 nM. It is much less potent at related kinases, with IC50 = 400 nM for TGF-β RII and IC50 = 1400 nM for mixed lineage kinase-7 (MLK-7), a kinase in the MAP kinase signal pathway and closely related to TGF-β RII. LY-364947 inhibits TGF-β-dependent cellular growth (IC50 = 81 nM) in NIH 3T3 mouse fibroblasts.

Novel dihydropyrrolopyrazole-substituted benzimidazoles were synthesized and evaluated in vitro as inhibitors of transforming growth factor-beta type I receptor (TGF-beta RI), TGF-beta RII, and mixed lineage kinase-7 (MLK-7). These compounds were found to be potent TGF-beta RI inhibitors and selective versus

Pyrazole-based inhibitors of the transforming growth factor-beta type I receptor kinase domain (TbetaR-I) are described. Examination of the SAR in both enzyme- and cell-based in vitro assays resulted in the emergence of two subseries featuring differing selectivity versus p38 MAP
