IUPAC Name: (3-((4-((2-amino-3-chloropyridin-4-yl)oxy)-3-fluorophenyl)carbamoyl)-5-(4-fluorophenyl)-4-oxopyridin-1(4H)-yl)methyl dihydrogen phosphate
InChIKey: KXDZWUPUSDCGDD-UHFFFAOYSA-N
SMILES: O=C(C1=CN(COP(O)(O)=O)C=C(C2=CC=C(F)C=C2)C1=O)NC3=CC=C(OC4=C(Cl)C(N)=NC=C4)C(F)=C3
Biological Activity: SCR-1481B1 (Metatinib anhydrous; c-Met inhibitor 2) is an inhibitor of the N-terminal fragment of Gasdermin D (GSDMD), with an IC50 of 1.04 μM and a Ka of 0.42 μM in mice. SCR-1481B1 effectively blocks GSDMD-NT oligomerization and pore formation, inhibits GSDMD-mediated pyroptosis (Pyroptosis), preserves mitochondrial integrity, and reduces proinflammatory cytokine secretion. SCR-1481B1 also inhibits angiogenesis, exerts GSDMD-independent antitumor effects, and enhances the infiltration of antitumor immune cells. SCR-1481B1 is also an inhibitor targeting to c-MET and VEGFR2, can be used in studies related to melanoma and sepsis[1][2][3][4].
