LDN-193189 2HCl

Description: LDN-193189 2HCl (DM-3189 2HCl) is a selective BMP signaling inhibitor that inhibits ALK1,ALK2,ALK3 and ALK6, showing IC50s of 0.8 nM, 0.8 nM, 5.3 nM, and 16.7 nM, respectively, in kinase assays.LDN-193189 2HCl inhibited the transcriptional activity of BMP type I receptors in C2C12 cells, with IC50s of 5 nM and 30 nM, respectively. LDN-193189 2HCl inhibited the transcriptional activity of BMP type I receptors ALK2 and ALK3 in C2C12 cells, with IC50s of 5 nM and 30 nM, respectively, and was 200-fold more selective for BMP than for TGF-beta. Target: TGF-beta/Smad, ALK. Smiles: C1(C2=C3N=CC(C4=CC=C(N5CCNCC5)C=C4)=CN3N=C2)=C6C=CC=CC6=NC=C1.Cl.Cl. References: Yu PB, et al.
