What is 6-[2-tert-Butyl-5-(6-methyl-pyridin-2-yl)-1H-imidazol-4-yl]-quinoxaline?
Description
SB-525334 is a potent inhibitor of the TGF-β receptor 1 (TGF-β R1, ALK5) kinase (IC50 = 14.36 nM). It is ~4-fold less effective against ALK4 and inactive against ALK2, ALK3, and ALK6. SB-525334 blocks TGF-β1-induced phosphorylation and nuclear translocation of SMAD2/3 as well as TGF-β1-directed gene expression. It is effective in vivo, preventing puromycin aminonucleoside-induced renal fibrosis and bleomycin-induced pulmonary fibrosis. SB-525334 also modulates carcinogenesis and suppresses the development of pulmonary arterial hypertension in animals.
The Uses of 6-[2-tert-Butyl-5-(6-methyl-pyridin-2-yl)-1H-imidazol-4-yl]-quinoxaline
SB-525334 was used to study TGFβ1-mediated human trophoblast differentiation.7
The Uses of 6-[2-tert-Butyl-5-(6-methyl-pyridin-2-yl)-1H-imidazol-4-yl]-quinoxaline
SB-525334 is a potent activin receptor-like kinase (ALK5)/ type I TGFβ-receptor kinase inhibitor with IC50 = 14.3 nM.
Definition
ChEBI: 6-[2-tert-butyl-5-(6-methyl-2-pyridinyl)-1H-imidazol-4-yl]quinoxaline is a quinoxaline derivative.
What are the applications of Application
TGF-β RI Kinase Inhibitor VIII is a potent ATP-competitive inhibitor against receptor TbR-I/ALK5
Biological Activity
Selective inhibitor of transforming growth factor- β receptor I (ALK5, TGF- β RI) (IC 50 = 14.3 nM). Inhibits TGF- β 1-induced smad2/3 nuclear localisation and TGF- β 1-induced mRNA expression in kidney cells. Attenuates bleomycin-induced pulmonary fibrosis.
