4-[1,1'-Biphenyl]-4-yl-1,4,5,6,7,8-hexahydro-2,7,7-trimethyl-5-oxo-3-quinolinecarboxylic acid ethyl ester
ITD-1 is a potent and highly selective TGFβ pathway inhibitor (IC₅₀ = 0.85 µM). ITD-1 promotes cardiomyocyte differentiation specifically via degradation of the TGFβ type II receptor (TGFBR2), effectively clearing the receptor from the cell surface and selectively inhibiting intracellular signaling (IC₅₀ = 0.4–0.8 µM), revealing a role for TGFβ signaling mechanism as a repressor of cardiomyocyte fate. ITD-1 does not induce differentiation of vascular smooth muscle cells or endothelial cells.
