Homologous complexants conformational factors

Bcl-2 is one of the many factors that control apoptosis, and overexpression of Bcl-2 has been observed in many different cancers. A homology model of Bcl-2 was derived from the NMR 3D structure of the Bcl-XL complex with a Bak BH3 peptide. This model served to search the NCI 3D database of 206,876 organic compounds for potential Bcl-2 inhibitors, which bind to the Bak BH3 binding site of Bcl-2. Full conformational flexibility of the ligands was taken into account in the program DOCK. Thirty-five potential inhibitors were tested, and seven of them had IC50 values from 1.6 to W.OpM.
