The conformation and activity relationship of fused analogs of DuP753 Original Research Article

We have prepared three conformationally restricted analogs of DuP753 in which one of the phenyl rings in the biphenyl moiety is fused to the imidazole ring, and have investigated the conformation-biological activity relationship of these compounds. Conformational analysis on DuP753 and these compounds confirms that a specific 3-dimensional arrangement of pharmacophoric elements is essential for biological activity.
