    WARNING: This product is for research use only, not for human or veterinary use.

MedKoo CAT#: 200492

CAS#: 915020-55-2 (free base)

Description: BGT226 is a phosphatidylinositol 3-kinase (PI3K) inhibitor with potential antineoplastic activity. PI3K inhibitor BGT226 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.

Price and Availability
