The present invention relates to small molecule antagonists of Bcl-2 family proteins such as Bcl-2 and/or Bcl-X
L
. In particular, the present invention provides non-peptide cell permeable small molecules (e.g., tricyclo-dibenzo-diazocine-dioxides) that bind to a pocket in Bcl-2/Bcl-X
L
that block the anti-apoptotic function of these proteins in cancer cells and tumor tissues exhibiting Bcl-2 protein overexpression. In preferred embodiments, the small molecules of the present invention are active at the BH3 binding pocket of Bcl-2 family proteins (e.g., Bcl-2, Bcl-X
L
, and Mcl-1). The compositions and methods of the present invention are useful therapeutics for cancerous diseases either alone or in combination with chemotherapeutic or other drugs.

The present invention relates to small molecule antagonists of Bcl-2 family proteins such as Bcl-2 and/or Bcl-XL. In particular, the present invention provides non-peptide cell permeable small molecules (e.g., tricyclo-dibenzo-diazocine-dioxides) that bind to a pocket in Bcl-2/BcI-XL that block the anti-apoptotic function of these proteins in cancer cells and tumor tissues exhibiting Bcl-2 protein overexpression. In preferred embodiments, the small molecules of the present invention are active at the BH3 binding pocket of Bcl-2 family proteins (e.g., Bcl-2, Bcl-XL, and Mcl-1). The compositions and methods of the present invention are useful therapeutics for cancerous diseases either alone or in combination with chemotherapeutic or other drugs.

database of 206 876 organic compounds to identify potential Bcl-2 small-moleculeinhibitors that bind to the BH3 binding site of Bcl-2. These potential Bcl-2 small-moleculeinhibitors were first tested in an in vitro binding assay for their potency in inhibition of the binding of a Bak BH3 peptide to Bcl-2. Thirty-five potential inhibitors were tested in this binding assay, and seven of them were found
