L-365260 is a potent and selective antagonist of non-peptide gastrin and brain cholecystokinin receptor (CCK-B), with Kis of 1.9 nM and 2.0 nM, respectively. L-365260 interacts in a stereoselective and competitive manner with guinea pig stomach gastrin and brain CCK receptors. L-365260 can enhance Morphine analgesia and prevents Morphine tolerance[1][2][3].
Lintitript (SR 27897) is a highly potent, selective, orally active, competitive and non-peptide cholecystokinin (CCK1) receptor antagonist with an EC50 of 6 nM and a Ki of 0.2 nM. Lintitript displays > 33-fold selectivity more selective for CCK1 than CCK2 receptors (EC50 value of 200 nM). Lintitript increases plasma concentration of leptin and food intake as well as plasma concentration of insulin[1][2][3].
Nastorazepide (Z-360) is a selective, orally available, 1,5-benzodiazepine-derivative gastrin/cholecystokinin 2 (CCK-2) receptor antagonist with potential antineoplastic activity. Target:CCK-2in vitro: Z-360 binds to the gastrin/CCK-2 receptor, thereby preventing receptor activation by gastrin, a peptide hormone frequently associated with the proliferation of gastrointestinal and pancreatic tumor cells. Check for active clinical trials or closed clinical trials using this agent. in vivo: Z-360 is a novel orally active CCK-2/gastrin receptor antagonist, significantly inhibits the growth of subcutaneous xenografts of human pancreatic tumor cells in mice, and that Z-360 combined with gemcitabine prolonged survival in a pancreatic carcinoma orthotopic xenograft mice.
JNJ-17156516 is a你orally active, potent, and selective cholecystokinin (CCK)1-receptor antagonist[1].
