General description
A cell-permeable quinazoline compound that acts as a potent inhibitor of NF-κB transcriptional activation (IC50 = 11 nM in Jurkat cells) and LPS-induced TNF-α production (IC50 = 7 nM in murine splenocytes). Does not exhibit cellular cytotoxicity even at concentrations as high as 10 µM. Reported to exhibit anti-inflammatory effects on carregeenin-induced paw edema in rats.

We disclose here a new structural class of low-molecular-weight inhibitors of NF-kappa B 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

House dust mites (HDMs) are known to trigger chronic inflammation through Toll-like receptors (TLRs) and their signalling cascades. In this study, we found that TLR2 ligation by HDMs induced the activation of dual oxidase 2 (Duox2) and nuclear factor-κB (NF-κB)
