Ordering Information

Biological Activity

Voxtalisib (XL765) Analogue is a dual inhibitor targeting phosphoinositide 3-kinase (PI3K) isoforms p110α, p110β, p110γ, and p110δ, as well as mammalian target of rapamycin (mTOR). By suppressing the downstream AKT/mTOR signaling axis, it blocks tumor cell survival and proliferation signaling pathways. Consequently, inhibition of this pathway reduces cell viability and suppresses growth in preclinical tumor models across multiple cancer types. [1][2]

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).
