NLRP3-IN-93
NLRP3-IN-93 is an orally active, blood-brain barrier-permeable NLRP3 inhibitor. NLRP3-IN-93 binds to the NACHT domain, blocks inflammasome assembly, and inhibits downstream IL-1β release, without significantly inhibiting various CYP isoforms. NLRP3-IN-93 demonstrates dose-dependent efficacy in mouse models of acute inflammation and Parkinson's disease, and exhibits good tolerability and an acceptable safety window in rats and dogs. NLRP3-IN-93 can be used in research on Parkinson's disease.

NLRP3-IN-93 (2 μM; 2 h) exhibits high permeability in the Caco-2 cell monolayer model (Papp A-B = 14.6 × 10-6 cm/s; Papp B-A = 32.6 × 10-6 cm/s), with a low efflux ratio (Efflux Ratio = 2.2)[1].
NLRP3-IN-93 (2.5 μL of 100 μM; 0.5-60 min) demonstrates good metabolic stability in liver microsomes across human and multiple animal species (T1/2: human >184 min, mouse 184 min, rat 184 min, dog >85 min, monkey >59 min)[1].
NLRP3-IN-93 (6 h) shows moderate plasma protein binding (human 65%, monkey 68%, dog 65%, rat 58%, mouse 61%) and high brain tissue binding (mouse 85%, rat 85%, monkey 86%)[1].
NLRP3-IN-93 (10 μM) shows no significant effects on 78 safety panel targets (receptors, enzymes, ion channels) and 58 kinase panel targets[1].

NLRP3-IN-93 (12.5-50 mg/kg; p.o.; twice daily; for 14 days) dose-dependently improves motor function in the MPTP (HY-15608)-induced subacute Parkinson's disease mouse model, including reduced beam traversal time and pole descent time[1].
NLRP3-IN-93 (50-300 mg/kg/day; p.o.; once daily; for 14 days) in repeat-dose toxicity studies in SD rats and Beagle dogs, induces hematological changes and minimally increased alveolar macrophage density in the lungs in rats at mid and high doses, and induces hematological and serum biochemical changes accompanied by minimal to mild thymic atrophy in dogs at the high dose. No adverse effects are observed at the mid-dose, indicating an acceptable safety window[1].
