We report the synthesis, binding affinities to the recombinant human somatostatin receptors, and structure-activity relationship studies of compounds related to the cyclic hexapeptide, c-[Pro6-Phe7-D-Trp8Lys9-Thr10-Phe11], L-363,301 (the numbering in the sequence refers to the position of the residues in native somatostatin)....

Earlier studies reported that the administration of L-tryptophan increased polyribosomal aggregation, protein synthesis and levels of cytoplasmic poly(A) mRNA in rat liver. This study was concerned with the effects of an L-tryptophan analog, D,L-beta-(1-naphthyl)alanine, in comparison with those of L-tryptophan....

Enantiopure L-azetidine-2-carboxylic acid, the (3R)-phenyl, (3R)-naphthyl and (3S)-isopropyl analogs were prepared based on a zinc-mediated asymmetric addition of allylic halides to the camphor sultam derivative of glyoxylic acid O-benzyl oxime.

Many antimicrobial peptides bear arginine (R)- and tryptophan (W)-rich sequence motifs. Based on the sequence Ac-RRWWRF-NH2, sets of linear and cyclic peptides were generated by changes in the amino acid sequence, L-D-amino acid exchange and naphthylalanine substituted for tryptophan. Linear...

Hydrolysis using 2H-labelled HCl and H2O, derivatization of free amino acids as N.O.S-trifluoroacetyl isobutyl esters, separation by gas chromatography on a chiral stationary phase and detection by mass spectrometry in selected-ion monitoring mode have been used in order to determine...
