The NLRP3 inflammasome is a multiprotein complex that activates caspase-1, leading to cleavage of pro-IL-1β and pro-IL-18 into their active forms. Therapeutic inhibition can occur at multiple points:
Inhibitor Modalities
Direct NLRP3 Inhibitors (e.g., MCC950, Dapansutrile)
Target ATPase activity of NLRP3
Prevent inflammasome assembly
Most advanced in CNS applications
Caspase-1 Inhibitors
Downstream target
Broader anti-inflammatory effects
Historical safety concerns
IL-1β Antagonists (e.g., Canakinumab, Anakinra)
Downstream cytokine blockade
Approved for autoimmune conditions
Limited CNS penetration
ASC Speck Inhibitors
Novel approach targeting aggregation
Preclinical stage
Potential for high specificity
