$85.00

ALK4/5/7 inhibitor for TGF-β/Smad pathway modulation

  • Potent, cell-permeable ALK4, ALK5, and ALK7 inhibitor for TGF-β/Activin/Nodal pathway modulation.
  • Blocks TGF-β-induced Smad activation and reduces ALK5-driven transcriptional activity in reporter assays.
  • Supports TGF-β/Smad, Wnt/β-catenin, and organoid-related workflows.
  • Reported to support iPSC generation and long-term self-renewal when used with PD0325901 and CHIR99021.
