McMillen, Nicholas Mort, Stephen Parsons, Edward C. R. Smith, Michal Vieth, Leonard C. Weir, Lei Yan, Faming Zhang, Jonathan M. YinglingPyrazole-based inhibitors of the transforming growth
factor-β type I receptor kinase domain (TβR-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 kinase. A
common binding mode at the active site has been established
by successful cocrystallization and X-ray analysis of potent
inhibitors with the TβR-I receptor kinase domain.
