title: Bridgehead-methyl analog of SC-53116 as a 5-HT4 agonist.
abstract: Pyrrolizidine benzamide (+/-)-2, the bridgehead-methyl analog of SC-53116, was prepared and evaluated for 5-HT(4) agonism activity in the rat tunica muscularis (TMM) mucosae assay. Compound (+/-)-2 has an EC(50) of 449 nM in the TMM assay, as compared to 23 nM for SC-53116, and 66 nM for the racemate of SC-53116.
