Abdullaha, Mohd;Ali, Mehboob;Kour, Dilpreet;Mudududdla, Ramesh;Khajuria, Parul;Kumar, Ajay;Bharate, Sandip B. research published 《 Tetramethoxystilbene Inhibits NLRP3 Inflammasome Assembly via Blocking the Oligomerization of Apoptosis-Associated Speck-like Protein Containing Caspase Recruitment Domain: In Vitro and In Vivo Evaluation》, the research content is summarized as follows. Nucleotide-binding domain leucine-rich repeat family pyrin domain containing 3 (NLRP3) inflammasome complex regulates the caspase-1 activity and subsequent processing of interleukin-1β (IL-1β). Various inflammatory diseases involve the activation of inflammasome complexes; thus, the intervention in complex formation via small mols. offers a new therapeutic opportunity. The structure-guided design and synthesis of a series of methoxystilbenes and methoxy-2-phenylnaphthalenes identified new inhibitors of NLRP3 inflammasome complex. The tetramethoxystilbene 4o and trimethoxy 2-phenylnaphthalene 1t inhibit the release of a mature form of IL-1β in J774A.1 cells with IC50 values of 1.39 and 2.07μM, resp. Mechanistic investigation revealed that tetramethoxystilbene 4o blocks the oligomerization of apoptosis-associated speck-like protein (ASC), which is the vital step in the formation of NLRP3 inflammasome assembly, thus preventing the activation of caspase-1 and the IL-1β release. Treatment of LPS+ATP challenged mice with 20 mg/kg of 4o significantly suppressed the levels of IL-1β. The data presented herein warrant further investigation of methoxystilbenes in disease-specific models of inflammatory diseases.
