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.

[Synthesis of sequence 1-34 of human parathyroid hormone]

TL;DR: I displays hypercalcemic activity in the thyroparathyroidectomized rat indicating that the amino terminal part also constitutes the hormonally active region of human parathyroid hormone.

Design of peptide oxytocin antagonists with strikingly higher affinities and selectivities for the human oxytocin receptor than atosiban.

TL;DR: Some new peptide OT antagonists which offer promise as superior tocolytics are presented which were evaluated for agonistic and antagonistic activities in in vitro and in vivo rat bioassays, in rat OT receptor (rOTR) binding assays and in human vasopressin (VP) vasopressor (V1a) receptor (hV3aR)binding assays.

Synthesis of a C-glycoside analogue of beta-D-galactosyl hydroxynorvaline and its use in immunological studies.

TL;DR: The results suggest that structural modifications of β‐D‐Gal‐Hyl264 in CII(256–270) may give altered peptide ligands that can be used for induction of tolerance in autoimmune rheumatoid arthritis.

Acceleration of the Passerini reaction in the presence of nucleophilic additives

TL;DR: In this paper, an accelerating effect of nucleophilic additives was revealed for the Passerini multi-component reaction, and the influence of aqueous solutions on the reaction rate was studied in detail and the direct involvement of water in the bond-making step was attributed as the basis of accelerating effect.
