Ordering Information

Biological Activity

OSI-930 is a potent multi-targeted receptor tyrosine kinase inhibitor that primarily targets c-Kit and VEGFR-2. By co-inhibiting c-Kit and VEGFR-2, OSI-930 blocks downstream receptor tyrosine kinase signaling pathways essential for cellular survival and vascular endothelial cell function. This dual target inhibition impairs tumor cell proliferation and suppresses tumor angiogenesis across various preclinical cancer models, including small cell lung cancer, glioblastoma, and renal cell carcinomas.

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
