Chemical Name: 4-[5,6-Dihydro-2-(6-methyl-2-pyridinyl)-4H-pyrrolo[1,2-b]pyrazol-3-yl]-6-quinolinecarboxamide
Biological ActivityGalunisertib is an ALK4 and ALK5 (TGFβRI) inhibitor (IC50 values are 77.7 and 172 nM, respectively). Also inhibits a range of other kinases with submicromolar IC50s including MINK, TGFβRII, ALK6 and ACVR2B. Inhibits TGFβ-induced SMAD phosphorylation in cancer cell lines in vitro and in vivo. Also reverses TGFβ-mediated suppression of T cell proliferation. Prevents TGFβ-mediated EMT and cell migration in vitro and exhibits antitumor efficacy in vivo. Used as component of growth media for urothelial organoids. Orally bioavailable.
