On cysteine and cystine peptides. 3. Synthesis of a fragment of insulin containing the intrachain disulfide bridge.
The application of methods developed mostly in this laboratory permitted the synthesis of the fully S,Nprotected heptapeptides N-carbobenzoxy-S-trityl-L-cysteinylS-diphenylmethylLExpand

N ω -linked arginine peptides
From Nα-trityl-L-arginine benzyl ester, Nω-glycyl-, Nω-L-valyl-, and Nω-L-arginyl-L-arginine have been prepared. These non-typical arginine peptides were transformed, especially in alkaline solution,Expand

Synthesis and catalytic properties of the pentapeptide, Thr-Ala-Cys-His-Asp.
The pentapeptide, Thr-Ala-Cys-His-Asp, has been synthesised by use of S-diphenylmethyl-protected cysteine. The catalytic activity towards p-nitrophenyl acetate was comparable with those of cysteineExpand

On Cysteine and Cystine Peptides
Of the amino acids found in natural peptides and proteins, cysteine and cystine fall into a special group. The specific properties of the sulfhydryl and corresponding disulfide groups becomeExpand

On cysteine and cystine peptides. Part VI. S-acylcysteines in peptide synthesis
S-p-Methoxybenzyloxycarbonyl-L-cysteine (pMZ-Cys)(I), as its N-o-nitrophenylsulphenyl derivative (II), can be used as an intermediate for the incorporation of cysteine residues in peptide synthesis.Expand
