Example sentences for: lerisetron
How can you use “lerisetron” in a sentence? Here are some example sentences to help you improve your vocabulary:
[ 28 ] . As was observed for 5-HT 3 R agonists, lerisetron binding was altered by the Y142A mutation.
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.
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.
This is a moderately small change for an alanine mutation, particularly considering that the smallest change in K i for removal of a functional group on lerisetron (the N-benzyl group) was 31 fold.
This result makes it much more difficult to assign the correct functional group to this amino acid since it suggests that one or both of the compounds is no longer binding the receptor in precisely the same manner as lerisetron.
