Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	NLRP3 ^[1] (in BMDM (bone marrow derived macrophages)) 7.5nM NLRP3 ^[1] (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.^[1]
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. ^[1]
