We report a second example of a general reaction screening approach to discover low molecular weight inhibitors of protein protein interactions. On the basis of the known pharmacophore model of SMAC mimetics, we predicted several inhibitors based on four different multicomponent reactions. The predicted inhibitors were subsequently synthesized, tested, and found to bind to the antiapoptotic protein X-linked inhibitor of apoptosis protein (XIAP) and showed cellular activity. Also the compounds are currently not highly potent. They could form a starting point for future medicinal chemistry optimization.
