Abstract

In this study, we have investigated the roles of substituents on the terminal phenyl ring at the C(4)-position of the quinazoline core to complete the structure-activity relationships (SARs) of our NF-kappa B activation inhibitors. Among them, compound 12j afforded highly potent inhibitory activity toward NF-kappa B transcriptional activation with IC(50) value of 2 nM, along with an excellent in vivo efficacy by reducing the edema formation seen in carrageenin-induced inflammation of the rat hind paw.
