Background:

K02288 is a highly selective inhibitor of ALK2 with IC50 value of 1.1nM [1].

K02288 is a 2-aminopyridine inhibitor of ALK2. It shows high selectivity for the homologous kinases ALK1-6 and ActRIIA. K02288 shows potency against the type I BMP receptors ALK1, ALK2 (IC50s range from 1–2nM), ALK3 and ALK6 (IC50s of 5–34nM), ALK4 (IC50 of 302nM) and ALK5 (IC50 of 321nM). K02288 has a favorable kinome-wide selectivity. In a panel of 200 human kinases, it shows more than 50% inhibition against only ABL and ARG at 0.1μM and only a further 6 kinases at 1μM [1].

K02288 also affects ALK2 related BMP signaling. In C2C12 cells, it reduces the phosphorylation of Smad dose-dependently when using BMP4 or BMP6 as ligands. Furthermore, K02288 induces a dorsalized phenotype in Tg(BRE:mRFP) transgenic zebrafish embryos [1].
