    A series of novel macrocyclic amide-urethanes was designed and synthesized based upon the X-ray crystal structure of our lead inhibitor (1, OM99-2 with eight residues) bound to memapsin 2. Ring size and substituent effects have been investigated. Cycloamide-urethanes containing 14- to 16-membered rings exhibited low nanomolar inhibitory potencies against human brain memapsin 2 (beta-secretase).
