Novel inhibitors of AP-1 and NF-κB mediated gene expression: structure–activity relationship studies of ethyl 4-[(3-Methyl-2,5-dioxo(3-pyrrolinyl))amino]-2-(trifluoromethyl)pyrimidine-5-carboxylate
摘要:
In an effort to identify novel inhibitors of AP-1 and NF-kappa B mediated transcriptional activation, several analogues of ethyl 4-[(3-methyl-2,5-dioxo(3-pyrrolinyl))amino]-2-(trifluoromethyl)pyrimidine-5-carboxylate (1) were synthesized and tested in two in vitro assays. The 2-(2'-thienyl) substituted compound (II) was identified as the most potent in this series. (C) 2000 Elsevier Science Ltd. All rights reserved.
