Description: JNJ-17156516 is a novel, potent, and selective cholecystokinin 1 receptor antagonist. JNJ-17156516 expressed high-affinity at the cloned human (pK(I) = 7.96 +/- 0.11), rat (pK(I) = 8.02 +/- 0.11), and canine (pK(I) = 7.98 +/- 0.04) CCK1 receptors, and it was also highly selective for the CCK1 receptor compared with the CCK2 receptor across the same species ( approximately 160-, approximately 230-, and approximately 75-fold, respectively).
