Functions

CPI-444 (1202402-40-1) is a potent (Ki = 3.54 nM) and selective adenosine A2A receptor antagonist. It blocked the induction of cAMP induced by NECA in HEK-293 cells with an IC50 = 17.03 nM. CPI-444 monotherapy or in combination with anti-PD-1, anti-PD-L1, and anti-CTLA-4 induced T-cell-mediated tumor responses, inhibited tumor growth, and enabled antitumor immune memory. Currently in clinical trials for multiple cancers.
