A chiral high-performance liquid-chromatographic separation method was developed for the analysis of some glycerol-based, ether-linked platelet-activating factor precursors. Using a D-naphthylalanine-type Pirkle-column and tetrahydrofuran-hexane eluents, the retention-structure relationships were determined for a large number of glycerol ether derivatives. The derivatives

In this paper, we investigated the structure-activity relationship of two vasopressin analogues, [Cpa(1),(L-1-Nal)(2) ]AVP (I) and [Cpa(1),(D-Nal)(2) ]AVP (II) by NMR spectroscopy and molecular modeling. Both peptides exhibit antioxytocic and antipressor potency. Inversion of configuration of the residue at position

Intrachain loop formation allows unfolded polypeptide chains to search for favorable interactions during protein folding. We applied triplet-triplet energy transfer between a xanthone moiety and naphthylalanine to directly measure loop formation in various unfolded polypeptide chains with loop regions consisting

A comparative monolayer and infrared study of analogues of gramicidin A containing either tyrosines or naphthylalanines instead of tryptophans indicates that the nature of the aromatic residues influences the favoured conformation of the peptides. Polar residues favour the single stranded
In order to study structure-activity relationships of enkephalin-related analogues, we report the biological activity and conformational analysis of four 14-membered cyclic enkephalin analogues with beta-(1-naphthyl) alanine in place of phenylalanine at the fourth position, Tyr-c[D-A2bu-Gly-(L and D)-beta Nal(1)-(L and D)-Leu].
