were 5-HT(4) receptorantagonists, including imidazopyridine amide 12h (SC-53606), which is a potent and selective 5-HT(4) receptorantagonist with a pA(2) value of 8.13 in the rat TMM assay. N-Methyl indole ester 13d was identified as a potent 5-HT(4) antagonist with a pA(2) value of 8.93. High selectivity was observed for these pyrrolizidine derivatives versus other monoamine receptors, including 5-HT(1)
