MedKoo CAT#: 201395

CAS#: 957054-30-7 (free base); 957054-33-0 (mesylate).

Description: Pictilisib, also known as Pictrelisib, GDC-0941, RG7321 and GNE0941 , is an orally bioavailable, and is a potent small-molecule thieno[3,2-d]pyrimidine inhibitor of the class I phosphatidylinositol 3 kinase (PI3K) isoforms p100alpha and p100delta with potential antineoplastic activity. PI3K inhibitor GDC-0941 selectively binds to PI3K isoforms in an ATP-competitive manner, inhibiting the production of the secondary messenger phosphatidylinositol-3,4,5-trisphosphate (PIP3) and activation of the PI3K/Akt signaling pathway; inhibition of tumor cell growth, motility and survival in susceptible tumor cell populations may result.
