NLRP3 is involved in the pathophysiology of several inflammatory diseases. Therefore, there is high current interest in the clinical development of new NLRP3 inflammasome small inhibitors to treat these diseases. Novel N-sulfonylureas were obtained by the replacement of the hexahydroindacene moiety of the previously described NLRP3 inhibitor MCC950. These new derivatives show moderate to high potency in inhibiting IL-1β release in vitro. The greatest effect was observed for compound 4b, which was similar to MCC950. Moreover, compound 4b was able to reduce caspase-1 activation, oligomerization of ASC, and therefore, IL-1β processing. Additional in silico predictions confirmed the safety profile of compound 4b, and in vitro studies in AML12 hepatic cells confirmed the absence of toxicological effects. Finally, we evaluated in vivo anti-inflammatory properties of compound 4b, which showed a significant anti-inflammatory effect and reduced mechanical hyperalgesia at 3 and 10 mg/kg (i.p.) in an in vivo mouse model of gout., J.E. thanks Fondo de Investigaciones Sanitarias (ISCIII/ FEDER) (Programa Miguel Servet: CP19/00005 and PI19/ 00082) and Fundación Mutua Madrileñ a.
