LY2157299

Research use only, not for human use.

LY2157299 (Galunisertib) is a potent, specific inhibitor of TGF-β receptor I kinase ((TGF-βRI) with IC50 of 56 nM.

LY2157299 (Galunisertib) is a potent, specific inhibitor of TGF-β receptor I kinase ((TGF-βRI) with IC50 of 56 nM; inhibits TGF-β-mediated SMAD2 activation and hematopoietic suppression in primary hematopoietic stem cells in a dose-dependent manner, stimulates hematopoiesis from primary MDS bone marrow specimens; ameliorates anemia in a TGF-β overexpressing transgenic mouse model of bone marrow failure; displays significant antitumor activity against both Calu6 and MX1 xenografts in mice.Blood Cancer Phase 3 Clinical(In Vitro):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.(In Vivo):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.
