Biological Activity for Obatoclax mesylate

Obatoclax mesylate is an inhibitor of Bcl-2 family members (IC50 values are 1.11 - 7 μM). Inhibits the interaction of a BH3 domain peptide with 6 members of the Bcl-2 family (Bcl-2, Bcl-XL, Mcl-1, Bcl-W, A1, and Bcl-B) in vitro. Has antiapoptotic and antitumor effects in several tumor bearing mouse models.
