Abstract: Naproxen, widely used to treat anti-inflammatory diseases, would cause serious of side effects. Based on the biological activities of cinnamic acid, naproxen derivatives containing cinnamic acid were designed, synthesized and used to enhance their anti-inflammatory activities and safeties. The results investigated that thirty novel naproxen derivatives had inhibitory effects on the nitric oxide (NO) release in RAW264.7 macrophage cells. A majority of naproxen derivatives showed the lower degree of cytotoxicity than that of naproxen. In vitro studies revealed that A22 (IC50 = 7.38 ± 1.96 µM) blocked the activation of nuclear transcription factor κB (NF-κB) signaling pathway and pyrin domain containing protein 3 (NLRP-3) inflammasome in a concentration dependent manner, thereby down-regulating the expression of pro-inflammatory cytokines, such as interleukin (IL)-1β, inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2). Docking studies confirmed that A22 exhibited a well-fitting into the NLRP3 active site. Accordingly, A22 might be a novel NLRP3 inhibitor to treat inflammatory diseases.
