Synthesis and structure activity relationships of novel non-peptidic metallo-aminopeptidase inhibitors
摘要:
Racemic derivatives of 3-amino-2-tetralone were synthesised and evaluated for their ability to inhibit metallo-aminopeptidase activities. New compounds substituted in position 2 by methyl ketone, substituted oximes or hydroxamic acids as well as heterocyclic derivatives were evaluated against representative members of zinc-dependent aminopeptidases: leucine aminopeptidase (E.C. 3.4.11.1), aminopeptidase-N(E.C. 3.4.11.2), Aeronumas proteolytica aminopeptidase (E.C. 3.4.11.10), and the aminopeptidase activity of leukotriene A(4) hydrolase (E.C. 3.3.2.6). Several compounds showed K-i values in the low micromolar range against the 'one-zinc' aminopeptidases, while most of them were rather poor inhibitors of the 'two-zinc' enzymes. This interesting selectivity profile may guide the design of new, specific inhibitors of target mammalian aminopeptidases with one active site zinc. (c) 2006 Elsevier Ltd. All rights reserved.

route to alkoxyamine hydrochloride derivatives is by reaction of alkyl bromides with N-hydroxyphthalimide or N-hydroxysuccinimide followed by addition of hydrazine and HCl. Transformation of an alkyl bromide to the corresponding alkoxyamine hydrochloride can be accomplished more rapidly in good yields without using hazardous hydrazine by reaction of (Boc)2NOH (N,N′-di-tert-butoxycarbonylhydroxylamine)

Compounds of formula (I):
[in which: R represents hydrogen, methyl or hydroxy; X represents an alkyl, alkenyl, cycloalkyl, aryl, aralkyl, or heterocyclic group; A represents a single bond, or an alkylene, alkenylene, alkynylene or alkadienylene group; Y represents hydrogen, or an aryl, cycloalkyl or heterocyclic group] have valuable antihypercholesteremic activities and may be used in the treatment of disorders arising from a blood cholesterol imbalance in humans and other animals. They may be prepared by introducing the group =NO-A-Y in place of an oxygen atom at the 4-position or introducing the group -O-CO-X in place of a hydroxy group at the 1-position in a corresponding compound in which the hydroxy group at the 16 position is protected and deprotecting that group.
