Abstract:
A silencer device for a firearm has a center portion including at least two substantially semi-circular chamber partition wall elements being spaced from one another in the longitudinal direction of the center portion, a housing portion into which the center portion is introduced, wherein between the at least two substantially semi-circular chamber partition wall elements and the inner wall of the housing portion at least one chamber is formed; and a positioning portion being at least connectable to the housing portion. The at least two substantially semi-circular chamber partition wall elements respectively comprise on their outer sides at least one chamfer, which form a lateral passage for explosive gases with the inner wall of the housing portion.

Abstract:
The present invention describes a method for the synthesis of enantiomerically pure 3-amidinophenylalanine derivatives, which are used as pharmaceutically effective urokinase inhibitors, by starting from 3-cyanophenylalanine derivatives. The methods of manufacture comprising only one synthesis step lead to new intermediates, namely 3-hydroxyamidino- and 3-amidrazonophenylalanine derivatives. These intermediates or their acetyl derivatives can be reduced into the desired 3-amidino-phenylalanine derivatives under gentle conditions (H2 or ammonium formiate, Pd/C (approx. 10%), ethanol/water, room temperature, normal pressure or also H2, Pd/C, AcOH or HCl/ethanol, 1-3 bar) in excellent yields and in an enantiomeric excess of up to 99.9%.

The invention also relates to the production of the compounds of general formula (I) and to a cosmetically active composition that contains at least one compound of formula (I).
Abstract:
The invention relates to compounds of general formula (I) and acid addition salts thereof, where the various symbols have the meanings given in the description and claims, the production and use thereof as substrate for the detection of TAFIa, a fibrinolysis inhibiting enzyme. The detection occurs by using the absorption between 400 and 412 nm, arising as a result of the formation of 3-carboxy-4-nitrothiophenol from Ellman's reagent as a function of time.

Abstract:
Process for the preparation of 2-methoxyimino-2-arylacetic esters of formula (I) in which R is C.sub.1 -C.sub.12 alkyl, which comprises reacting an appropriately substituted boronic acid of general formula (II) or the trimeric form (lII) herein, which is in equilibrium with it, in the presence of a Pd catalyst, with a methoxyiminoacetic ester of formula (IV) in which R is C.sub.1 -C.sub.12 alkyl and X is a leaving group. According to a further process variant, in principle the groups which split off the two reactants may change places. The process can be applied not only to phenyl derivatives but also to larger ring systems (naphthyl, pyridyl, heterocycles).
