Ordering Information

Biological Activity

Pamufetinib (TAS-115) is a potent dual kinase inhibitor targeting VEGFR2 (IC50 30 nM) and MET (IC50 32 nM). By inhibiting receptor autophosphorylation of VEGFR2 and MET, it suppresses downstream HGF/MET and VEGF/VEGFR signaling pathways. This dual target blockade leads to the inhibition of endothelial cell proliferation, tube formation, and tumor angiogenesis, while concurrently suppressing cancer cell survival and migration in MET-dependent tumors.

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).
