Abstract

Several rationally designed pyrimidine-based scaffolds intended to mimic the spatial projection of the i, i+3, and i+7 residues of an α-helix and also possess improved aqueous solubility were prepared. A Biginelli-oxidation process was used to form the central pyrimidine ring of these scaffolds, which was subsequently manipulated to form pyrimidine-based tercyclic α-helix mimetics. A pyrimidine-based scaffold designed to mimic the α-helical BH3 domain of the pro-apoptotic Bak protein was also prepared as a putative inhibitor of the Bcl-xL/Bak protein-protein interaction. The pyrimidine-based tercyclic α-helix mimetics, and the putative Bcl-xL inhibitor, were assessed using a luminescence com..
