title: Novel N-[1-(1-substituted 4-piperidinylmethyl)-4-piperidinyl]benzamides as potent colonic prokinetic agents.
abstract: A series of novel N-[1-(1-substituted 4-piperidinylmethyl)-4-piperidinyl]benzamides was prepared and its compounds were evaluated for their binding to 5-HT(4) receptors and effects on gastrointestinal motility in conscious dogs. 4-Amino-N-[1-[1-(4-aminobutyl)-4-piperidinylmethyl]-4-piperidinyl]-5-chloro-2-methoxybenzamide (15) was found to have a potent binding affinity for 5-HT(4) receptors (IC(50): 6.47nM) and showed excellent colonic prokinetic activity.
