OSI-930 Usage And Synthesis

Uses

OSI-930 is an inhibitor of the receptor tyrosine kinases c-Kit (IC50:9.5nM) and VEGFR-2 (IC50:10.1nM).

Definition

ChEBI: 3-(4-quinolinylmethylamino)-N-[4-(trifluoromethoxy)phenyl]-2-thiophenecarboxamide is an aromatic amide.

Biological Activity

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].
