OSI-930 is a novel, potent inhibitor of Flt1, kinase insert domain receptor (KDR), CSF-1R, Lck, c-Raf and activated receptor tyrosine kinases Kit with IC50 values of 8, 9, 15, 22, 41 and 80 nM, respectively [1].

OSI-930 has been demonstrated to inhibit proliferation and induce apoptosis in the HMC-1 cell line which is highly dependent on Kit signaling for survival. On the contrary, OSI-930 revealed no growth inhibition of COLO-205 cell line under normal culture conditions [1].

OSI-930 has shown to time- and concentration-dependently inactivate P450 3A4. Additionally, OSI-930 could reduce CO difference spectra of P450 3A4 [2].
