4-[[(1R)-2-[[(2R)-3-(1H-INDOL-3-YL)-2-METHYL-1-OXO-2-[[(TRICYCLO[3.3.1.13,7]DEC-2-YLOXY)CARBONYL]AMINO]PROPYL]AMINO]-1-PHENYLETHYL]AMINO]-4-OXOBUTANOIC ACID

CI-988 is a potent and selective cholecystokinin 2 (CCK-2) receptor antagonist that displays ~ 1600-fold selectivity over CCK1 receptors and has negligible affinity at other binding sites. CI-988 exhibits anxiolytic activity following oral administration. CI-98 inhibited the proliferation of small cell lung cancer (SCLC) cells in mice.

Potent and selective CCK 2 (CCK-B) receptor antagonist that displays ~ 1600-fold selectivity over CCK 1 receptors (IC 50 values are 1.7 and 2717 nM for CCK 2 and CCK 1 respectively). Has negligible affinity at a range of other binding sites (IC 50 > 10 μ M). Exhibits anxiolytic activity following oral administration.
