Alosetron (GR 68755) (Z)-2-butenedioate is a potent and highly selective serotonin 5-HT3 receptor antagonist. Alosetron (Z)-2-butenedioate is used for the research of irritable bowel syndrome (IBS). Alosetron (Z)-2-butenedioate blocks the fast 5HT3-mediated depolarisation of guinea-pig myenteric and submucosal neurons, with IC50 at ~55 nM.
