ABT-263, a newly developed Bcl-2 inhibitor, was efficiently synthesized. The key intermediates 4-(4-[2-(4-chlorophenyl)-5,5-dimethylcyclohex-1-enyl]methyl}piperazin-1-yl)benzoic acid and 4-fluoro-3-[(trifluoromethyl)sulfonyl]benzenesulfonamide were efficiently prepared by a three-component Mannich reaction and by nucleophilic fluorination of 1-nitro-2-[(trifluoromethyl)sulfonyl]benzene as the key steps, respectively. Our work may lay a foundation for a new process development of this promising anticancer drug candidate.

We validate a practical methodology for the rapid profiling of small molecule inhibitors of proteinâprotein interactions. We find that a well known BH3 family inhibitor can potently inhibit the p53/hDM2 interaction.
