Discovery of quinazolines as a novel structural class of potent inhibitors of NF-κB activation
摘要:
We disclose here a new structural class of low-molecular-weight inhibitors of NF-kappaB activation that were designed and synthesized by starting from quinazoline derivative 6a. Structure-activity relationship (SAR) studies based on 6a elucidated the structural requirements essential for the inhibitory activity toward NF-kappaB transcriptional activation, and led to the identification of the 6-amino-4-phenethylaminoquinazoline skeleton as the basic framework. In this series of compounds, 11q, containing the 4-phenoxyphenethyl moiety at the C(4)-position, showed strong inhibitory effects on both NF-kappaB transcriptional activation and TNF-alpha production. Furthermore, 11q exhibited an anti-inflammatory effect on carrageenin-induced paw edema in rats. (C) 2002 Elsevier Science Ltd. All rights reserved.

Structure–activity relationships of quinazoline derivatives: dual-acting compounds with inhibitory activities toward both TNF-α production and T Cell proliferation
We synthesized 4-chlorophenethylaminoquinazoline derivatives and evaluated their inhibitory activities toward both TNF-alpha production and T cell proliferation responses; Compound 2f, containing a piperazine ring at the C(7)-position of the quinazoline ring, exhibited more potent inhibitory activities toward both than the lead compound 1a. A smaller N-substituent in the piperazine ring was required for inhibition of TNF-alpha production. (C) 2001 Elsevier Science Ltd. All rights reserved.
