IN-1130 is a highly selective transforming growth factor-β type I receptor kinase (ALK5) inhibitor with an IC50 of 5.3 nM for ALK5-mediated Smad3 phosphorylation. IN-1130 inhibits ALK5 phosphorylation of casein (IC50=36 nM) and p38α mitogen-activated protein kinase (IC50=4.3 μM). IN-1130 suppresses renal fibrosis in obstructive nephropathy and blocks breast cancer lung metastasis[1][2].
IN-1130 (0.5, 1 μM; for 2 hours) inhibits TGF-β-stimulated Smad2 phosphorylation and subsequent nuclear translocation in HepG2 and 4T1 cells[2]. ?
IN-1130 (1 μM; for 72 hours) restores the TGF-β-mediated decrease in E-cadherin protein expression. IN-1130 (1 μM; for 72 hours) inhibits TGF-β-induced MMPs mRNA expression and the gelatinolytic activity of secreted MMPs in MCF10A cells[2]. ?
IN-1130 (1 μM; pretreated for 30 min) inhibits TGF-β-induced MDA-MB-231 cells, NMuMG, and MCF10A cells mobility and invasion[2].
IN-1130 (10, 20 mg/kg/day; IP; for 7 and 14 days) reduces the extent of interstitial nephritis and fibrosis (arrowheads) with 10 mg/kg and significantly reduces or absent histopathological changes with 20 mg/kg in unilateral ureteral obstruction (UUO) rats[1]. ?
IN-1130 (10, 20 mg/kg/day; for 14 days) dose-dependently decreases levels of TGF-β1 mRNA and suppresses phosphorylation of Smad2, α-SMA, myofibroblasts in rat UUO kidneys[1]. ?
IN-1130 (40 mg/kg; IP; 3 times per week for 3 weeks) inhibits in vivo breast cancer metastasis to the lungs in MMTV/c-Neu mice (Eight-week-old female BALB/c mice)[2].
