MedKoo Cat#: 202100 | Name: OSI-930
Featured New

Description:

WARNING: This product is for research use only, not for human or veterinary use.

OSI-930 is a selective thiophene-derived tyrosine kinase inhibitor with potential antineoplastic activity. Tyrosine kinase inhibitor OSI-930 inhibits stem cell factor receptor (c-Kit) and the vascular endothelial growth factor receptor 2 (VEGFR2), which may result in the inhibition of both tumor cell proliferation and tumor angiogenesis. Both c-Kit and VEGFR2 are overexpressed in a variety of cancers. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus).

More Info
OSI-930 is a novel inhibitor of the receptor tyrosine kinases Kit and kinase insert domain receptor (KDR), which is currently being evaluated in clinical studies. OSI-930 selectively inhibits Kit and KDR with similar potency in intact cells and also inhibits these targets in vivo following oral dosing.

Instruction

Biological target:
OSI-930 is an orally selective inhibitor of Kit, KDR and CSF-1R (c-Fms) with IC50s of 80 nM, 9 nM and 15 nM.
In vitro activity:
Results showed that OSI-930 inactivated purified, recombinant cytochrome P450 (P450) 3A4 in the reconstituted system in a mechanism-based manner. The inactivation of 3A4 by OSI-930 was time- and concentration-dependent. Modeling studies on the binding of OSI-930 to the active site of the P450 3A4 indicated that OSI-930 would be oriented properly in the active site for oxidation of the thiophene sulfur to give the sulfoxide, which has previously been shown to be a significant metabolite of OSI-930. Reference: Drug Metab Dispos. 2011 Feb;39(2):345-50. https://pubmed.ncbi.nlm.nih.gov/21068193/
In vivo activity:
The data suggest that antitumor activity of OSI-930 in mouse xenograft models is observed at dose levels that maintain a significant level of inhibition of the molecular targets of OSI-930 for a prolonged period. Furthermore, pharmacokinetic evaluation of the plasma exposure levels of OSI-930 at these effective dose levels provides an estimate of the target plasma concentrations that may be required to achieve prolonged inhibition of Kit and KDR in humans and which would therefore be expected to yield a therapeutic benefit in future clinical evaluations of OSI-930.
