Discovery of MDV6058 (PF-06952229), a selective and potent TGFβR1 inhibitor: Design, synthesis and optimization

Bioorg Med Chem Lett. 2022 Nov 1:75:128979. doi: 10.1016/j.bmcl.2022.128979. Epub 2022 Sep 8.

Abstract

Compound 1 is a potent TGF-β receptor type-1 (TGFβR1 or ALK5) inhibitor but is metabolically unstable. A solvent-exposed part of this molecule was used to analogue and modulate cell activity, liver microsome stability and mouse pharmacokinetics. The evolution of SAR that led to the selection of 2 (MDV6058 / PF-06952229) as a preclinical lead compound is described.

Keywords: ALK5; Cancer; PF-06952229; TGFβR1; pSMAD2.
