TLDR
In this article, the authors show that 1-Hydroxy-benzotriazol and 1-hydroxy-acetyl carbodiimid-methode eignen sich als Zusatze bei der Dicyclohexylcarbodiimids-Methode zur Synthese von Peptiden, verhindern die N-Acyl-harnstoffbildung and fuhren in hoher Ausbeute.
Abstract
1-Hydroxy-benzotriazol sowie verschiedene kernsubstituierte 1-Hydroxy-benzotriazole eignen sich als Zusatze bei der Dicyclohexylcarbodiimid-Methode zur Synthese von Peptiden. Ihr Einflus auf die Racemisierung bei Peptidsynthesen wurde unter Anwendung des gaschromatographischen Racemisierungstests von Weygand u. Mitarbb.2) untersucht. Die neuen Zusatze senken die Racemisierung, verhindern die N-Acyl-harnstoffbildung und fuhren in hoher Ausbeute zu sehr reinen Peptiden.

Immunomodulatory activity of analog of muramyl dipeptide and their use as adjunct to chemotherapy of Leishmania donovani in hamster.

TL;DR: These peptides were found quite effective in both the modes as adjunct to chemotherapy with stibanate (SSG) against Leishmania donovani infection in golden hamster and in adjunct use the treatment may require lower dose of SSG to reduce the chances of drug toxicity.

Biofunctional evaluation of a hydrogen bond stabilizing the conformation in the cyclic part of oxytocin.

TL;DR: It is concluded that devoid of the hydrogen bond under question, an oxytocin-like peptide can still assume the conformation needed to interact with the Oxytocin receptors.

Peptide, 981) Synthese der A‐Kette des Schafinsulins mit S‐Tetrahydropyranylschutz

TL;DR: In this paper, the A-Kette des Schafinsulins wurde in vollstandig geschutzter Form synthetisiert, in which the acid labile protecting groups used were: tert. butyl substitution for carboxylic and hydroxy functions, tetrahydropyranyl for the thiol function, and 2-(p-biphenylyl)isopropyloxycarbonyl group for amine protection.
