Structure determination of the inactive S554A variant of prolyl oligopeptidase complexed with an octapeptide has shown that substrate binding is restricted to the P4-P2' region. In addition, it has revealed a hydrogen bond network of potential catalytic importance not detected

N-Benzoxycarbonylglycyl-L-proline (L-ZGP) has been introduced as a chiral selector for enantioseparation of amines in non-aqueous capillary electrophoresis. Methanol mixed with different proportions of dichloromethane, 1,2-dichloroethane or 2-propanol containing L-ZGP and ammonium acetate was used as the background electrolyte. Enantioseparation of

A normal-phase chromatographic method for the determination of (R)- and (S)-propranolol in plasma is described. The chiral separation is performed by adding an optically active complexing agent, N-benzoxycarbonylglycyl-L-proline, to the mobile phase (dichloromethane). The solid phase is LiChrosorb DIOL. After

Direct separation of enantiomeric amines using mainly N-benzyloxycarbonylglycyl-L-proline (L-ZGP) but also N-benzyloxycarbonylglyclglcyl-L-proline (L-ZGGP) as the chiral counter ion in methanol is described. The solid phase was Hypercarb porous graphitic carbon. Several amines of pharmacological interest (e.g., alprenolol, sotalol, terbutaline, promethazine

A stereoselective HPLC method is described for the determination of (SR)- and (RS)-mefloquine in plasma. The direct chiral separation is carried out on a Hypercarb-S column (porous graphitised carbon) with N-benzyloxycarbonyl-glycyl-L-proline (L-ZGP) as a chiral counter-ion in a reversed-phase system.
