LDN-193189 2HCl

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-β.
