AG-041R is a potent CCK-BR (gastrin/cholecystokinin-2 (CCKB) receptor) antagonist that exhibits selective binding for CCKB compared to CCKA. AG-041R inhibits gastrin-evoked secretion of pancreastatin (IC50 = 2.2 nM) as well as gastrin-induced histamine release and cell growth of Mastomys ECL carcinoid tumor cells. AG-041R (1 muM) exhibits synergistic inhibitory effects on the cell viability of human gastric cancer cells when administered with the selective COX-2 inhibitor NS-398 at 10 muM.
