Abstract

Racemic 5-substituted 7-aminobenzocyclohepten-6-one were synthesized and evaluated for their ability to inhibit metalloaminopeptidase activities. Unexpectedly, 5-thio substituted compounds showed enhanced inhibition potency with K(i) values in the nanomolar range against the 'one zinc' aminopeptidases from the M1 family, while most of them were rather poor inhibitors of the 'two zincs' enzymes from the M17 family. This interesting selectivity profile may guide the design of new, specific inhibitors of target mammalian aminopeptidases with one active site zinc.
