Crystal Structure of a cycloamide-urethane-derived novel inhibitor bound to human brain memapsin 2 (beta-secretase).

Overview

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).

About this Structure

1XS7 is a Single protein structure of sequence from Homo sapiens with MMI as ligand. Active as Memapsin 2, with EC number 3.4.23.46 Full crystallographic information is available from OCA.
