Leuprolide acetate (pGlu-His-Trp-Ser-Tyr-d-Leu-Leu-Arg-Pro-NHEt), a potent LHRH agonist in wide clinical use, was characterized conformationally by NMR and circular dichroism. It displayed quite different preferred conformations under different solution conditions: two low population beta-turns in water, a nascent helix in TFE/water at low pH, and a high population beta-turn in TFE/water at slightly acidic pH. The pH-related conformational change in TFE/water is attributed to the pK(a) of the acetate counterion, not to ionizable groups on the peptide. None of these conformations are in exact agreement with previous computational predictions.
