ANQ 11125 is a selective antagonist of motilin receptor with pKd of 8.24 [1].

Motilin receptor is a G protein-coupled receptor for motilin and stimulates contraction of gut smooth muscle.

ANQ 11125 is a selective motilin receptor antagonist. The affinity of ANQ 11125 for motilin receptor is about 10 times less than motilin [1]. In rabbit antral smooth muscle tissue, ANQ-11125 bound to motilin receptor with pKd value of 8.16. While, ANQ-11125 didn’t induce contractions of rabbit duodenum. ANQ-11125 (10-5 M) induced contractile response by 29% compared to ACh [2].
