K02288 is a potent inhibitor of BMP signaling. K02288 has in vitro activity against ALK2 at low nanomolar concentrations similar to the current lead compound LDN-193189. K02288 specifically inhibited the BMP-induced Smad pathway without affecting TGF-β signaling and induced dorsalization of zebrafish embryos.

K02288 reduces a robust phosphorylation of Smad1/5/8 induced by BMP4 stimulation, with an apparent IC50 of 100 nM. K02288 causes near complete inhibition of Smad2 phosphorylation at 0.5 µM. K02288 binds to ALK1 in an ATP-mimetic fashion with two hydrogen bonds to the kinase hinge. K02288 also inhibits BMP9-ALK1 signalling, and induces a hypersprouting phenotype in HUVECs.
K02288 (1 µM) induces dysfunctional angiogenesis in a chick embryo CAM model.
