Mechanism of Action

Targets/IC₅₀/Ki	NLRP3 (in BMDM (bone marrow derived macrophages)) 7.5nM NLRP3 (in HMDM) 8.1 nM
In vitro	MCC950 inhibits canonical and noncanonical NLRP3 activation in BMDM and HMDM cells at IC50 of 7.5 and 8.1nM. MCC950 specifically inhibits activation of NLRP3 but not the AIM2, NLRC4 or NLRP1 inflammasomes.
In vivo	MCC950 reduces interleukin-1β (IL-1β) production and attenuates the severity of experimental autoimmune encephalomyelitis (EAE). Furthermore, MCC950 treatment rescues neonatal lethality in a mouse model of CAPS and is active in ex vivo samples from individuals with Muckle-Wells syndrome.
