title: Structure-activity relationships of 6-fluoroquinazolines: dual-acting compounds with inhibitory activities toward both TNF-alpha production and T cell proliferation.
abstract: We synthesized various 6-fluoro-7-(1-piperazino)quinazolines based on the structure of 1 and evaluated their inhibitory activities toward both TNF-alpha production and T cell proliferation responses. Among these compounds, 7a, having the 3,4-(methylenedioxy)phenyl moiety at the C(4)-position of the quinazoline ring, showed both inhibitory activities. Furthermore, the oral treatment with 7a exhibited an anti-inflammatory effect in rats with adjuvant arthritis as well as an inhibitory activity toward LPS-induced TNF-alpha production.
