tgfβri in 1

TGFβRI-IN-1 is an orally active and selective inhibitor of TGFβ receptor type I (TGFβRI) kinase, with IC50 values of 2 nM and 7.6 μM for TGFβRI and TGFβRII, respectively.

TGFβRI-IN-5 (Compound 4b) is a potent TGFβRI inhibitor with an IC50 of 0.08 μM, demonstrating significant anticancer activity by enhancing apoptosis and arresting the G2/M phase of the cell cycle in all tested cell lines[1].

ALK5-IN-8 is a highly effective inhibitor of TGFβRI (ALK5). It hinders the phosphorylation of ALK5 on downstream signaling proteins (Smad2 or Smad3) by obstructing the interaction between TGFβRI and ligands. Consequently, it disrupts or prevents TGF-β signaling. ALK5-IN-8 shows promise in the study of diverse diseases associated with ALK5-mediated pathways[1].

TGFβRI-IN-3 is a highly selective TGFβR1 inhibitor with an IC50 of 0.79 nM and exhibits 2000-fold selectivity against MAP4K4, showing potential applications in immuno-oncology [1].
