The complex secondary metabolite anachelin, isolated from the freshwater cyanobacterium Anabaena cylindrica, is believed to act as siderophore, facilitating iron uptake. Its structure is characterized by a fascinating blend of polyketide, peptide, and alka ...
This contribution describes the synthesis of polyphenylene dendrimers that are functionalized with up to 16 lysine residues or substituted with short peptide sequences composed of 5 lysine or glutamic acid repeats and a C- or N-terminal cysteine residue. P ...
Lipophilicity of compounds with therapeutic interest represents one of the most important physicochemical parameters in predicting and interpreting transport processes across biological barriers. This property is commonly measured as a drug | membrane part ...
The puromycin-sensitive aminopeptidase (PSA) is thought to contribute to the degradation of enkephalins. Besides being the most abundant aminopeptidase in the brain, PSA is expressed in other organs as well. From a human fetal brain cDNA library, we have i ...
16-Membered meta,para-cyclophanes mimicking the vancomycin binding pocket (D-O-E ring) are designed and synthesized. The structural features of these biaryl ether contg. macrocycles are: (a) the deletion of the carboxyl group of vancomycin's central amino ...
alpha -Isocyano-beta -phenylpropionamide is synthesized from the corresponding amino acid in excellent yield. The unique reactivity of this bifunctional compd. is exploited for the development of novel multicomponent synthesis of 5-aminooxazole, pyrrolo[3, ...
A balanced supplementation method was applied to develop a serum and protein- free medium supporting hybridoma cell batch culture. The aim was to improve systematically the initial formulation of the medium to prevent limitations due to unbalanced concns. ...
Angiotensin-I-converting enzyme (ACE) inhibitory activity was identified in milk proteins fermented with Lactobacillus (Lb.) helveticus NCC 2765 (Nestle Culture Collection, Vers-chez-les-Blanc, Switzerland). Hydrolyzing sodium caseinate for 1 and 2 h inhib ...
Two representatives of a new type of beta-amino acids, carrying two functionalized side chains, one in the 2- and one in the 3-position, have been prepd. stereoselectively: a beta-Ser deriv. with an addnl. CH2OH group in the 2-position, for beta-peptides w ...
