Novel conformationally constrained derivatives of classical 5-HT(3) receptor antagonists were designed and synthesized with the aim of probing the central 5-HT(3) receptor recognition site in a systematic way. The newly-synthesized compounds were tested for their potential ability to inhibit [(3)H]granisetron specific binding to 5-HT(3) receptor in rat cortical membranes. These studies revealed subnanomolar
