compound 13a [PMID: 23639540]   

GtoPdb Ligand ID: 8155

Compound class: Synthetic organic
Comment: The discovery of compound 13a is reported in [1], a medicinal chemistry study to identify selective bone morphogenetic protein receptor (BMP) inhibitors. Compound 13a inhibits the majority of Type I receptor serine/threonine kinases to a greater or lesser extent, but is most potent at ALK1 (ACVRL1) and ALK2 (ACVR1) which are activin receptor components, and ALK3 (BMPR1A) and ALK6 (BMPR1B) which are bone morphogenetic protein receptors. Compound 13a has its most potent inhibitory effect on TGFBR2 and VEGFR2, with approximately 25 times lower potency against BMPR2 and AMPK, where reported IC50s are more akin to those at the Type I receptor serine/threonine kinases [1].
