Rapid and efficient synthesis of a novel series of substituted aminobenzosuberone derivatives as potent, selective, non-peptidic neutral aminopeptidase inhibitors
摘要:
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. (C) 2012 Elsevier Ltd. All rights reserved.

A production process for substituted phenylacetic acids or ester analogues thereof is disclosed. In this process toluene or toluene substituted with various substituents, an alcohol, an oxidant and carbon monoxide are used as raw materials to obtain compounds comprising structure of phenylacetic acid ester or analogues thereof by catalysis of the complex catalyst formed from transition metal and ligand, and such compounds are hydrolyzed to obtain various substituted phenylacetic acid based compounds. This type of compounds and their derivatives serve as important fine chemicals used widely in the industries of pharmaceuticals, pesticides, perfume and the like.

synthesis of aromatic cyclic ketones. The behaviour of cyclopropyl acyl radicals is also described, in particular the 8-endo-trig cyclisation of 3-substituted cyclopropyl acyl radicals to give bicyclo[6.1.0]nonanones, and in the synthesis of cyclic enol lactones.
This paper describes the design and synthesis of compounds belonging to a novelclass of highly selective mammalian CD13 inhibitors. Racemic homologues of 3-amino-2-tetralone 1 were synthesised and evaluated for their ability to selectively inhibit the membrane-bound, zinc-dependent aminopeptidase-N/CD13 (EC 3.4.11.2). Some of these novel non-peptidic compounds are potent, competitive inhibitors of
moieties at the benzo[7]annulene scaffold on the GluN2B affinity and cytoprotective activity was analyzed. The key intermediate for the synthesis of OH-substituted benzo[7]annulenamines 11-13 and 17 was the epoxyketone 8. Reductive epoxide opening of 8 resulted with high regioselectivity in the 5-hydroxyketone 9 (Pd(OAc)2, HCO2H, phosphane ligand) or the 6-hydroxyketone 10 (H2, Pd/C), whereas hydrolysis
