Motilin Receptor
GSK 962040 is a selective motilin receptor agonist with pEC50 value of 7.9. It is effective as a stimulant of human and rabbit gastrointestinal motility. lt represents a new opportunity as a treatment in diabetic gastroparesis. It is discovered as a therapeutic agent for conditions associated with delayed gastric emptying. It is highly selective against motilin receptor over the human ghrelin receptor and hERG. It also has no significant activity against other receptors including 5-HT, adrenergic, dopamine, histamine and adenosine receptors. It is found to enhance the EFS-induced cholinergic contraction and cause a small muscle contraction at high concentration in rabbit isolated gastric antrum. It also induces the contraction of human-isolated stomach preparations at 10μM. It had no significant activity at a range of other receptors (including ghrelin), ion channels and enzymes in vitro. It was preferred because its initial IC50 values at CYP3A4 were significantly higher than our preferred threshold of 10 μM. It induced phasic contractions, the duration of which was dose-related. It strongly facilitated cholinergic activity in the antrum, with lower activity in fundus and small intestine only. It was developed by glaxosmithkline and has been in Cilinic Phase 2.

1.Discovery of N-(3-fluorophenyl)-1-[(4-([(3S)-3-methyl-1-piperazinyl]methyl)phenyl)acetyl]-4-piperidinamine (GSK962040), the first small molecule motilin receptor agonist clinical candidate.

N-(3-fluorophenyl)-1-[(4-([(3S)-3-methyl-1-piperazinyl]methyl)phenyl)acetyl]-4-piperidinamine 12 (GSK962040) is a novel small molecule motilin receptor agonist. It possesses excellent activity at the recombinant human motilin receptor and also at the native rabbit motilin receptor where its agonist activity results in potentiation of the amplitude of neuronal-mediated contractions of isolated gastric antrum tissue. Compound 12 also possesses highly promising pharmacokinetic profiles in both rat and dog, and these results, in combination with further profiling in human native tissue and an in vivo model of gastrointestinal transit in the rabbit, have led to its selection as a candidate for further development.

BACKGROUND: GSK962040, a small molecule motilin receptor agonist, was identified to address the need for a safe, efficacious gastric prokinetic agent. However, as laboratory rodents lack a functional motilin system, studies in vivo have been limited to a single dose, which increased defecation in rabbits. Motilin agonists do not usually increase human colonic motility, so gastric prokinetic activity needs to be demonstrated.

There is an urgent clinical need for a safe, efficacious stimulant of gastric emptying; current therapies include erythromycin (an antibiotic with additional properties which preclude chronic use) and metoclopramide (a 5-hydroxytryptamine type 4 receptor agonist and an antagonist at brain D2 receptors, associated with movement disorders). To move away from the complex motilide structure of erythromycin, a small molecule motilin receptor agonist, GSK962040, was identified and characterized. The compound was evaluated using recombinant human receptors, rabbit and human isolated stomach preparations known to respond to motilin and in vivo, by measuring its ability to increase defecation in conscious rabbits. At the human motilin receptor, the pEC50 (the negative logarithm to base 10 of the EC50 value, the concentration of agonist that produces 50% of the maximal response) values for GSK962040 and erythromycin as agonists were, respectively, 7.
