    Activity GW-2580 is a potent and selective inhibitor of cFMS/CSF-1 receptor kinase, shown to completely and selectively inhibit human cFMS kinase activity at 60 nM, and fully suppress CSF-1 induced cell growth at 1 μM, in vitro. Orally bioavailable and active in vivo1. GW 2580 also binds to TrkB, TrkC and TrkA with Kd values of 36 nM, 120 nM and 630 nM, respectively,2 and fully inhibits BDNF-induced TrkB phosphorylation in cells at 3 µM3.

    Scientific background

    GW-2580 is a small-molecule pyrimidine derivative, that acts as a potent and selective inhibitor of Colony-stimulating factor 1 (CSF-1) signaling through cFMS kinase receptor. GW-2580 completely inhibits human cFMS kinase in vitro at 0.06 μM1

    The compound also acts as an inhibitor of Trk Receptors and shows binding towards TrkB, TrkC, and TrkA with Kd values of 36 nM, 120 nM and 630 nM, respectively2 and fully inhibits BDNF-induced TrkB phosphorylation in cells at 3 µM3.
