MCC950 sodium salt (CP-456773)

Biological Activity

MCC950 (CP-456773) sodium salt was found to act as a cytokine release inhibitory drug and inhibitor of the NLRP3 inflammasome. CP-456773 sodium salt inhibits interleukin 1β (IL-1β) secretion and caspase 1 processing.

	Method	i.p.
	Cell Lines	mice
	Concentrations	10 mg/kg
	Incubation Time	24 h
	Results	More interestingly, we found that sevoflurane abolished the OVA-induced expression of NLRP3, which is similar to that observed in MCC950-treated allergic mice.

	Cell Lines	mice
	Concentrations	10 mg/kg
	Incubation Time	24 h
	Results	As expected, OVA challenge significantly increased the production of serum IgE compared with that of the control groups. Sevoflurane or MCC950 treatment significantly decreased OVA-induced IgE levels, although these levels remained higher than those in the control mice

	Method	i.p.
	Cell Lines	mice
	Concentrations	10 mg/kg
	Incubation Time	24 h
	Results	Sevoflurane or MCC950 treatment resulted in a marked reduction in goblet cell hyperplasia (Figures 4(a)-4(f))

	Cell Lines	mice
	Concentrations	10 mg/kg
	Incubation Time	24 h
	Results	Treatment with sevoflurane or MCC950 produced a profound reduction in the total numbers and differential counts of inflammatory cells in BALF

	Method	i.p.
	Cell Lines	mice
	Concentrations	10 mg/kg
	Incubation Time	24 h
	Results	OVA challenge significantly increased the inflammatory cells concentrated near the airways (Figure 2(c)), while sevoflurane or MCC950 treatment resulted in a marked decrease in inflammatory cell infiltration (Figures 2(d)-2(f)).

	Concentrations	50 mg/kg
	Incubation Time	24 hr
	Results	When compared with the vehicle group, MCC950, the NLRP3 inhibitor significantly reduced the neurological deficit score 24 hr after cerebral ischemia reperfusion in diabetic mice

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the K_m factor for a mouse and then divide by the K_m factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
