Structure-activity relationships of quinazoline derivatives: dual-acting compounds with inhibitory activities toward both TNF-alpha production and T cell proliferation.

摘要

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 la. A smaller N-substituent in the piperazine ring was required for inhibition of TNF-alpha production.
