5HT3 receptor antagonist identified via extensive SARstudies was endo-5-chloro-2,3-dihydro-2,2-dimethyl-N-(8-methyl-8-azabicyclo[3.2.1]oc t- 3-yl)-7-benzofurancarboxamide (Z)-2-butenedioate (zatosetron maleate). The 7-carbamyl regiochemistry, dimethyl substitution, chloro substituent, and endo stereochemistry were all crucial elements of the SAR. Zatosetron maleate was a potentantagonist of 5HT-induced
