Synthesis and structure–activity relationship of cyclopentenone oximes as novel inhibitors of the production of tumor necrosis factor-α
摘要:
3-Alkyl-2-aryl-2-cyclopenten-1-one oxime derivatives (1) were studied as a novel class of inhibitors of tumor necrosis factor alpha (TNF-alpha) with regard to synthesis and in vitro SAR inhibition of TNF-alpha. The in vitro IC50 values of these compounds in rat and human peripheral blood mononuclear cells were at the sub-micromolar level. (C) 2014 Elsevier Ltd. All rights reserved.

2-cyclopenten-1-one oxime derivatives represented by Formula (I), or pharmaceutically acceptable salts thereof inhibit the production of TNF-α or PDE4, and therefore show therapeutic effect in inflammatory or immunological disorders mediated through TNF-α or PDE4.

The reaction of organometallic reagents with vinylogous esters (Stork–Danheiser transposition) provides direct access to 3-substituted cyclic enones. However, the reaction typically fails with sterically hindered aryl or alkyl nucleophiles due to competing enolization. Cerium(III) chloride and other lanthanide salts have traditionally been used to mitigate the basicity and enhance the nucleophilic
