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	A2AR 3.54 nM(Ki)
In vitro	CPI-444 restores T-cell activation in vitro.
In vivo	CPI-444 treatment resulted in a similar inhibition of tumor growth in the B16F10 melanoma (100 mg/kg) and RENCA renal cell cancer syngeneic models (10 mg/kg). It enhances T-cell activation in both the periphery and tumor microenvironment.
