CAS#: 934493-76-2

Description: Voxtalisib, also known as XL-765 and SAR245409, is a PI3K/mTOR dual kinase inhibitor XL765 is an orally bioavailable small molecule targeting the phosphatidylinositol 3 kinase (PI3K) and mammalian target of rapamycin (mTOR) kinases in the PI3K/mTOR signaling pathway, with potential antineoplastic activity. PI3K/mTOR dual kinase inhibitor XL765 inhibits both PI3K kinase and mTOR kinase, which may result in tumor cell apoptosis and growth inhibition in susceptible tumor cell populations.
