Biological Activity for A 1331852

A 1331852 is a high affinity and selective Bcl-xL inhibitor (Ki <0.01 nM), also inhibits Bcl-W, Bcl-2, and Mcl-1 (Ki values are 4, 6 and 142 nM, respectively). A 1331852 inhibits Bcl-xL-dependent Molt 4 acute lymphoblastic leukemia cell growth in vitro (EC50 = 6 nM). It enhances antitumor effects of Docetaxel (Cat. No. 4056) and Venetoclax (Cat. No. 6960) in xenograft models of breast and lung cancer. A 1331852 also induces apoptosis in and clears senescent biliary epithelial cells (BECs), and induces apoptosis in xenograft models of EBV-associated T- and natural killer cell lymphoma.

Pathways for A 1331852

Apoptosis Signaling Pathway

Apoptosis Signaling Pathway

Apoptosis is a physiological process for cell death that is critical during aging and development. It may also be referred to as cell 'suicide'. Apoptosis can be triggered by events both inside and outside of the cell.
