A83-01 --- an ALK inhibibitor.. CAS# 909910-43-6

A83-01 --- an ALK inhibibitor., CAS No. 909910-43-6, is an ALK inhibibitor. It was found that A-83-01 inhibited the transcriptional activity induced by TGF-beta type I receptor ALK-5 and that by activin type IB receptor ALK-4 and nodal type I receptor ALK-7, the kinase domains of which are structurally highly related to those of ALK-5. A-83-01 was found to be more potent in the inhibition of ALK5 than a previously described ALK-5 inhibitor, SB-431542, and also to prevent phosphorylation of Smad2/3 and the growth inhibition induced by TGF-beta. A-83-01 inhibited the epithelial-to-mesenchymal transition induced by TGF-beta, suggesting that A-83-01 and related molecules may be useful for preventing the progression of advanced cancers.
