Binding Studies Were Performed With Appropriate Ligands And Tissue Preparations Allowing The Discrimination Of The Three Tachykinin Binding Sites,Nk-1,Nk-2,And Nk-3. The Potencies Of These Agonists Were Evaluated In The Guinea Pig Ileum Bioassay. According To The Binding Data,We Can Conclude That The S-7 Subsite Is Small,Only The Gauche (-) Probe [(2S,3S)-Ing(7)]Sp Presents A High Affinity For Specific Nk-1 Binding Sites. Surprisingly,The [delta(E)Phe(7)]Sp Analogue,Which Projects The Aromatic Ring Toward The Trans Orientation,Is Over 40-Fold More Potent Than The Z Isomer,[delta(Z)Phe(7)]Sp. A Plausible Explanation Of These Conflictual Results Is That Either The Binding Protein Quenches The Minor Trans Rotamer Of [(2S,3S)-Ing(7)]Sp In Solution Or This Constrained Amino Acid Side Chain Rotates When Inserted In The Protein. In Position 8,The High Binding Affinities Of [flg(8)]Sp And [(2S,3S)-Bfi(8)]Sp Suggest That The S-8 Subsite Is Large Enough To Accept Two Aromatic Rings In The Gauche (-) And One Aromatic Ring In The Trans Direction. Peptides Bearing Two Conformational Probes In Positions 7,8,Or 9 Led To Postulate That S-7,S-8,And S-9 Subsites Are Independent From Each Other. The Volumes Available For Side Chains 7 And 8 Can Be Estimated To Be Close To 110 And 240 Angstrom(3),Respectively. The Large Volume Of The S-8 Subsite Raises Question On The Localization Of The Sp-Binding Site In The Nk-1 Receptor. If Sp Were To Bind In The Transmembrane Domains,The Cleft Defined By The Seven Transmembrane Segments Must Rearrange During The Binding Process In Order To Bind A Peptide In An Ac-Helical Structure And At Least One Large Binding Subsite In Position 8. Thus,Indirect Topographical Analysis With Constrained Amino Acids Might Contribute To The Analysis Of The Receptor/ligand Dynamics. Finally,This Study Demonstrates That A Good Knowledge Of The Peptidic Backbone Structure And A Combination Of Constrained Amino Acids Are Prerequisites To Confidently Attribute The Preferred Orientation(S) Of An Amino Acid Side Chain.
