Excessive inflammation caused by abnormal activation of the NLRP3 inflammasome contributes to the pathogenesis of multiple human diseases, but clinical drugs targeting the NLRP3 inflammasome are still not available. In this study, we identify entrectinib (ENB), a US Food and Drug Administration (FDA)-approved anti-cancer agent, as a target inhibitor of the NLRP3 inflammasome to treat related diseases. ENB specifically blocks NLRP3 without affecting activation of other inflammasomes. Furthermore, we demonstrate that ENB directly binds to arginine 121 (R121) of NEK7 and blocks the interaction between NEK7 and NLRP3, thereby inhibiting inflammasome assembly and activation. In vivo studies show that ENB has a significant ameliorative effect on mouse models of NLRP3 inflammasome-related diseases, including lipopolysaccharide (LPS)-induced systemic inflammation, monosodium urate (MSU)-induced peritonitis, and high-fat diet (HFD)-induced type 2 diabetes (T2D). These data show that ENB is a targeted inhibitor of NEK7 with strong anti-NLRP3 inflammasome activity, making it a potential candidate drug for the treatment of inflammasome-related diseases.

Long-term use of naproxen can lead to serious side effects. Inspired by the biological activity of cinnamic acid, a series of cinnamic acid derivatives containing naproxen were designed, synthesized and explored their anti-inflammatory activities and mechanism in vitro. Our results indicated that all of naproxen derivatives showed more significant inhibition against lipopolysaccharide (LPS)-induced nitric oxide (NO) production and had lower degree of cytotoxicity than that of naproxen.

Ambient particulate matter (PM) exposure is a known risk factor for cardiovascular diseases. Epidemiological studies have shown the association between PM exposure and vascular complications, including vasculitis, embolism, hypertension, stroke, and atherosclerosis. However, the exact mechanisms underlying its vascular toxicity, especially in relation to short-term exposures, remain incompletely understood.

Background: Lipotoxicity is a significant factor in the pathogenesis of diabetic cardiomyopathy (DbCM), a condition characterized by mitochondrial fragmentation and pyroptosis. Mitochondrial fission protein 1 (FIS1) plays a role in mitochondrial fission by anchoring dynamin-related protein 1 (DRP1). However, the specific contribution of FIS1 to DbCM remains unclear.

Ethnopharmacological Relevance: Mangifera indica (family Anacardiaceae), often acknowledged as mango and renowned for being a plant of diverse ethnopharmacological background since ancient times, harbors the polyphenolic bioactive constituent, mangiferin (MNG). MNG is a major phytochemical of Mangifera indica and other plants with a wide range of reported pharmacological activities, including antioxidant, anti-inflammatory, neuroprotective and hepatoprotective effects. MNG has also been utilized in traditional medicine; it is reportedly a major bioactive element in over 40 polyherbal products in traditional Chinese medicine (TCM), and two prominent anti-inflammatory, immunomodulatory and antiviral Cuban formulations.

Occupational exposure to crystalline silica is etiologically linked to an increased incidence of systemic sclerosis (SSc), also called Erasmus syndrome. The underlying mechanisms of silica-related SSc are still poorly understood. We demonstrated that early and repeated silica exposure contribute to the severity of SSc symptoms in the hypochloric acid (HOCl)-induced SSc mouse model.
