General description

A cell-permeable, bioavailable, non-toxic sulfonylurea derived compound that selectively interacts with NLRP3 inflammasome and prevents its activation in a reversible manner with no effect on NLRC4 and NLRP1. Dose-dependently reduces IL-1β production (IC50 = 7.5 & 8.1 nM in LPS & ATP-treated BMDMs & HMDMs, respectively) with minimal effect on IL-1α & TNF-α. Specifically blocks NLRP3-dependent pyroptotic cell death by inhibiting caspase-1 &-11 activation, IL-1β processing and ASC oligomerization. Does neither block K+ efflux, Ca2+ flux or NLRP3-ASC interactions nor inhibit NLRC4, AIM2, TLR signaling or NLRP3 priming. Effectively suppresses T cell responses and IL-1β & IL-6 secretion, and reduces the severity of EAE and rescues neonatal lethality in a mouse model of CAPS (10 mg/kg, i.p., q.d. & 20 mg/kg, i.p., every other day, respectively). Displays attractive PK profile with desirable microsomal stability and minimal liability towards CYP450 isozymes (<15% inhibition at 10 µM) & hERG (IC50 >30 µM).
