Discovery of novel motilin antagonists: Conversion of tetrapeptide leads to orally available peptidomimetics
摘要:
We successfully discovered peptidomimetic motilin antagonists (17c and 17d) through the improvement of physicochemical properties of a tetrapeptide antagonist (2). Furthermore, with oral administration and based on motilin antagonistic activity, both compounds suppressed motilin-induced colonic and gastric motility in conscious dogs.
