NLRP3 plays a role in various inflammatory diseases, making the development of NLRP3 inflammasome small inhibitors a current area of interest. New N-sulfonylureas were obtained by modifying a previously described NLRP3 inhibitor, MCC950, and these derivatives showed potent inhibitory effects on IL-1 beta release. Compound 4b exhibited the greatest effect, similar to MCC950, and also showed a reduction in caspase-1 activation and IL-1 beta processing. In silico predictions confirmed the safety profile of compound 4b, and in vitro and in vivo studies further supported its anti-inflammatory properties.
NLRP3 is involved in the pathophysiology ofseveral inflammatory diseases. Therefore, there is high currentinterest in the clinical development of new NLRP3 inflammasomesmall inhibitors to treat these diseases. NovelN-sulfonylureas wereobtained by the replacement of the hexahydroindacene moiety ofthe previously described NLRP3 inhibitor MCC950. These newderivatives show moderate to high potency in inhibiting IL-1 beta release in vitro. The greatest effect was observed for compound4b,which was similar to MCC950. Moreover, compound4bwas ableto reduce caspase-1 activation, oligomerization of ASC, andtherefore, IL-1 beta processing. Additional in silico predictionsconfirmed the safety profile of compound4b, and in vitro studiesin AML12 hepatic cells confirmed the absence of toxicologicaleffects. Finally, we evaluated in vivo anti-inflammatory properties of compound4b, which showed a significant anti-inflammatoryeffect and reduced mechanical hyperalgesia at 3 and 10 mg/kg (i.p.) in an in vivo mouse model of gout.
