Abstract: The invention relates to a method for producing C-terminal amidated dibasic or polybasic peptides, consisting in reacting two peptides in the presence of trypsin biologically active enzymes and, if necessary, in purifying the thus obtainable compounds of formula (I) by means of protein chemistry.

Abstract: The invention relates to the production of carboxy-terminal (C-terminal) amidified peptides with C-terminal amidified lysin, in particular with the biological activity of GLP-1, the chemical and/or biotechnological precursors and intermediate products thereof. The invention also relates to a method for the production and use thereof for producing pharmaceutical products.

Abstract: The invention relates generally to a process for preparing diarylcycloalkyl derivatives of the formula (I). wherein the respective R-group substituents are defined herein. These compounds of formula (I) are activators for peroxisome proliferator-activated receptors (PPAR activators) which are useful in the therapeutic treatment of a number of diseases and disorders of the central nervous system such as multiple sclerosis, Parkinson's Disease, psychiatric disorders and the like. The present invention is a novel process for preparing PPAR activators of the formula (I) which do not have the disadvantages of the processes known in the prior art. In particular, a process is provided with which the PPAR activators of formula (I) can be prepared in a suitable enantiomeric excess, i.e. high enantioselectivity, without the need for subsequent chiral chromatography.

Abstract: The invention relates generally to intermediate compounds derived during the process for preparing diarylcycloalkyl derivatives which are activators for peroxisome proliferator-activated receptors (PPAR activators) and are therefore useful in the therapeutic treatment of a number of diseases and disorders of the central nervous system such as multiple sclerosis, Parkinson's Disease, psychiatric disorders and the like. The intermediate compounds of the present invention are defined structurally by the formulae (Ia): and formula (II): wherein the respective substituent groups are defined herein.

Abstract: An enzymatic process permitting the enantiomeric resolution of amino acids is provided. More specifically, this process for separating the enantiomers of an amino acid comprises treating a racemic mixture of the amino acid with glutaric anhydride and then with the enzyme glutaryl-7-ACA acylase so as to recover one of the enantiomers of the amino acid, the other enantiomer remaining in the form of the corresponding glutarylamide derivative.
