Galunisertib (LY2157299) is an oral and selective TGF-β receptor type I (TGF-βRI) kinase inhibitor with an IC50 of 56 nM.
Galunisertib (LY2157299) (0.1, 1, 10, and 100 μM) displays a slight dose-dependent potentiation of Bay 43-9006 in SK-Sora, HepG2, and Hep3B cell lines but not in JHH6, SK-HEP1, and HuH7 cell lines[2].
Human xenografts Calu6 (non-small cell lung cancer) and MX1 (breast cancer) are implanted subcutaneously in nude mice. After oral administration of 75 mg/kg, Galunisertib (LY2157299) induces a 70% decrease in pSmad for both types of cell lines. The time at which pSmad recovered 80% of baseline is approximately 6 h after administration[3].
