Description
Curator's Comment: Description was created based on several sources, including http://www.selleckchem.com/products/XL765(SAR245409).html https://www.ncbi.nlm.nih.gov/pubmed/25300944

Voxtalisib (SAR245409, XL765) is an orally available inhibitor of PI3K and the mammalian target of rapamycin (mTOR), which are frequently activated in human tumors and play central roles in tumor cell proliferation. Exelixis discovered Voxtalisib internally and out-licensed the compound to Sanofi. Voxtalisib is being evaluated by Sanofi as a single agent and in multiple combination regimens in a variety of cancer indications. Clinical trials have included a single agent phase 2 trial in Non-Hodgkin’s lymphoma, combination phase 1b/2 trials with temozolomide in patients with glioblastoma, with letrozole in hormone receptor positive breast cancer, with bendamustine and/or rituximab in lymphoma or leukemia, and a phase 1 trial in combination with a MEK inhibitor. Voxtalisib is a highly selective, potent and reversible ATP-competitive inhibitor of pan-Class I PI3K (α, β, γ, and δ) and mTORC1/mTORC2. It is orally active, highly selective over 130 other protein kinases. In cellular assays, XL765 inhibits the formation of PIP3 in the membrane, and inhibits phosphorylation of AKT, p70S6K, and S6 phosphorylation in multiple tumor cell lines with different genetic alterations affecting the PI3K pathway.
