P1, P2'-linked macrocyclic amine derivatives as matrix metalloproteinase inhibitors.

A novel series of 13- and 14-membered macrocyclic amines was developed by linking the P1 and P2' groups. The synthesis entails stereoselective Frater alkylation to install the anti-succinate configuration and macrocyclic amination via nucleophilic displacement. This strategy resulted in a new class of conformationally constrained inhibitors that are potent and selective for MMP-8 and 9 over MMP-1 and 3.
