Crizotinib (PF-02341066) is an ATP-competitive small-molecule tyrosine kinase inhibitor of c-MET (IC50: 8 nM) and ALK (IC50: 20 nM) receptors.

Masitinib (AB1010) is a tyrosine-kinase inhibitor used in the treatment of mast cell tumors in animals, specifically dogs. Since its introduction in November 2008 it has been distributed under the commercial name Masivet. It has been available in Europe since the second part of 2009. In the USA it is distributed under the name Kinavet and has been available for veterinaries since 2011.

DMH-1 is a potent and selective Bone Morphogenetic Protein (BMP) inhibitor.

ALK-IN-1 (AP26113) is a potent ALK inhibitor with IC50 of 0.62 nM in a cell-free assay, demonstrated ability overcome Crizotinib resistance mediated by a L1196M mutation. Phase 2.

SB-431542 is an inhibitor of ALK5/TGF-β type I Receptor (IC50=94 nM) and is selective. SB 431542 also has inhibitory activity against ALK4 and ALK7 but not other proteins. SB 431542 can be used for induced differentiation of stem cells.

Alectinib hydrochloride (RO5424802 Hydrochloride) is a selective, and orally available inhibitor of ALK( IC50 : 1.9 nM)

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.

Y15 (1,2,4,5-Benzenetetramine tetrahydrochlor) is a potent and specificsmall-molecule FAK scaffolding inhibitor that inhibits its autophosphorylation activity, blocks tumor growth.
