Description: Dactolisib, also known as BEZ235, is an orally bioavailable phosphatidylinositol 3-kinase (PI3K) inhibitor with potential antineoplastic activity. PI3K inhibitor BEZ235 specifically inhibits PIK3 in the PI3K/AKT kinase (or protein kinase B) signaling pathway, which may trigger the translocation of cytosolic Bax to the mitochondrial outer membrane, increasing mitochondrial membrane permeability; apoptotic cell death may ensue. Bax is a member of the proapoptotic Bcl2 family of proteins.

Additional Information

BEZ235 is a dual phosphatidylinositol 3-kinase (PI(3)K)/mammalian target of rapamycin (mTOR) inhibitor that is orally available and that has been shown to be effective in several malignancies in vitro. Recently, BEZ235 entered clinical trials for solid tumors.
