NLRP3
NLRP3 (NLR Family Pyrin Domain Containing 3) is a cytosolic pattern-recognition receptor that functions as the sensor component of the NLRP3 inflammasome, enabling innate immune cells to detect microbial motifs, endogenous danger signals, and environmental irritants[1]. Upon activation, NLRP3 oligomerizes and recruits the adaptor ASC and pro-caspase-1, leading to inflammasome assembly, caspase-1 activation, and subsequent maturation of the pro-inflammatory cytokines IL-1β and IL-18 as well as gasdermin D-mediated pyroptosis[1][2]. Mechanistically, canonical NLRP3 activation requires a priming step that enhances NLRP3 and pro-inflammatory cytokine expression, followed by an activation step triggered by diverse stimuli including extracellular ATP, microbial toxins, silica particles, and monosodium urate crystals[2]. Through these signaling processes, NLRP3 regulates inflammation, host defense, and immune homeostasis, while excessive activation promotes pathological inflammatory responses[1][3]. Dysregulated NLRP3 inflammasome activity has been implicated in autoinflammatory syndromes, gout, cardiovascular disease, neurodegenerative disorders, inflammatory bowel disease, and other inflammation-associated conditions[1][3][4]. Compared with other inflammasome-forming NOD-like receptors such as NLRP1 and NLRC4, NLRP3 is distinguished by its ability to respond to an exceptionally broad spectrum of pathogen-associated and danger-associated signals rather than a limited set of ligands[1][4]. For experimental applications, selective NLRP3 inhibitors such as MCC950 suppress inflammasome assembly by targeting the NACHT domain and are widely used to investigate NLRP3-dependent inflammatory mechanisms in preclinical disease models[4].

Tabersonine hydrochloride
0 ImagesTabersonine hydrochloride is a selective, orally active NLRP3 inhibitor. Tabersonine hydrochloride directly binds to the NACHT domain of NLRP3, inhibiting its ATPase activity and oligomerization, thereby blocking ASC spot formation and caspase-1 activation, and reducing the release of pro-inflammatory cytokines such as IL-1β. Tabersonine hydrochloride also inhibits K63-linked ubiquitination of TRAF6, blocking NF-κB, PI3K/Akt, and p38 MAPK signaling pathways. Tabersonine hydrochloride can inhibit inflammatory responses, induce apoptosis of liver cancer cells through mitochondrial pathways and death receptor pathways, reduce mitochondrial membrane potential, promote cytochrome c release, and activate caspase proteins. Tabersonine hydrochloride is mainly used in the study of NLRP3-driven inflammatory diseases (such as acute lung injury, sepsis, peritonitis) and tumors such as liver cancer.
