a 83 01

A 83-01 (ALK5 Inhibitor IV) is an inhibitor of the TGF-β type I receptors ALK5, ALK4, and ALK7 (IC50=12 45 7.5 nM). A 83-01 promotes the reprogramming of mouse fibroblasts into iPSCs. A 83-01 can be used in organoid cultures.

A 83-01 sodium salt is a potent inhibitor of TGF-β type I receptor ALK5 kinase, ALK4 and ALK7, with IC 50 s of 12 nM, 45 nM and 7.5 nM against the ALK5, ALK4 and ALK7 induced transcription, respectively [1].

AS8351 (NSC51355) is a histone demethylase inhibitor. It has been used in combination with CHIR99021, A 83-01, BIX01294, SC-1, Y-27632, OAC2, SU 16f, and JNJ-10198409 to induce reprogramming of human fetal lung fibroblasts into functional cardiomyocytes.
