This article describes the synthesis of two analogues of β-corticotropin-(l-24)-tetracosapeptide, in which the amidine function in one or in all three arginyl residues has been replaced by hydrogen. In connection with previous work, the weak biologi

A synthesis is described of a protected pentapeptide, in which the amino-acid sequence L-alanyl-D-glutamyl-L-lysyl-D-alanyl-D-alanine, found in bacterial cell wall substances, is present. By the nature of its amino- and carboxyl-protecting groups it

This report describes the formation of a non-covalent complex between two tryptic peptides of horse heart cytochrome-c. All amino functions of cytochrome-c were completely protected with the methylsulfonylethyloxycarbonyl (Msc) group. Trypsin split t

Modification of the methyl group in 2-(methylsulphonyl)ethanol gave alcohols which could be used to introduce amino-protective groups of the urethane type, which are labile in alkaline media. The cleavage involves β-elimination. Exchange of the meth

As a model study for the usefulness of the synthetic action of a proteinase in the semisynthesis of large polypeptides, a heme peptide, comprising the residues 1-38 of horse heart cytochrome-c and bearing protective functions on the ϵ-amino groups,

The synthesis of the model compound Aloc-Ala-Ala-Dma-Ala-Ala-OMe has been described as an illustration of the fact that a large group reversibly alkylating the amido group of an oligomer can disturb the regularity of a peptide backbone, oppose its ag

Two new ACTH-analogues, an octadecapeptide amide and a tetracosapeptide containing the lower homologue of arginine (norarginine) in position 8, have been synthesized by the generally accepted method. Special attention was paid to the synthesis of the

The synthesis of p-isothiocyanatobenzoylhomoserine lactone from DL-homoserine as well as from L-methionine is described. The compound constitutes a good tool in the solid phase Edman degradation of tryptic protein fragments terminated by lysine.

Six sulphated octapeptide amide analogues, representing the C-terminal sequence of pancreozymin have been prepared in addition to the natural sequence. The tryptophyl residue which is essential for biological activity was replaced in this series by s
