Importance of the N-benzyl and distal piperazine nitrogen to binding of lerisetron
Another possibility would be the N-benzyl interaction, however, since the Y152A mutation also produced a large increase in K i for analog 2, this conclusion is not supported by our data.
The interaction is included in the model based on structural information obtained from the crystal structure of AChBP [ 27 ] . The region of this protein homologous to loop E and loop D of the 5-HT 3A receptor suggests a loop structure from Y140 to Y152 and a 3-residue turn containing a glycine at position 147 and the β-strand from W89 through Y93 oriented as shown in Figure 6. The orientation of lerisetron between W89 and Y142A as shown would enable the N-benzyl group to be positioned in close proximity to R91.
The model for lerisetron binding will be further refined as its interactions with other binding site amino acids are investigated [ 26 32 33 ] . Of particular interest would be potential interactions of the N-benzyl group that would account for the decrease in binding affinity of analog 2. Additional information gained from comparison of our model with the recent crystal structure of the AChBP demonstrates that lerisetron can be roughly 'fit' into the binding site such that all the residues line up as shown in our model.
Removal of the N-benzyl group produced a 80-fold decrease in affinity, indicating a role for this group in interacting with the 5-HT 3 R. Other studies have supported this observation and suggest a more specific electrostatic interaction [ 23 ] .
