摘要:
La presente invención se refiere a varios haptenos derivados de bromopropilato(BP), sus usos para Ia síntesis de inmunoreactivos así como un método inmunoquímico para Ia detección y/o cuantificación de bromopropilato (BP) y sus respectivos kits. La estructura química de los haptenos empleados, tanto para Ia inmovilización en el soporte sólido como para Ia inmunización de animales para obtener los respectivos anticuerpos policlonales, se ha diseñado para maximizar el reconocimiento del grupo bis-bromofenil del BP por parte de los anticuerpos generados. El método de Ia presente invención se refiere a un análisis inmunoquímico indirecto capaz de detectar BP con un umbral de 0.14 μg-L-1 y pesticidas relacionados que contienen un grupo bis-halofenil en su estructura. Además, el BP se puede analizar directamente en muestras de vino.

摘要:
The present invention relates generally to amino acid derivatives and to methods of making the same. In particular, the invention relates to compounds bearing a stereochemical identity, that is, the same stereochemistry, with the chiral alpha -carbon of D- alpha -amino acids and their use in methods of therapy, including the treatment of inflammatory diseases, and to compositions and enantiomeric mixtures containing them.

Compounds containing a specific branched chain end terminal group, which is isopropyl, sec .-butyl, or tert .-butyl; a polar leading group; and long-chain aliphatic, non-cyclic, saturated or unsaturated, hydrocarbon group linking them; and having anti-cancer and immune boosting activity.
摘要:
The invention relates to a method for hydrogenating organic compounds containing at least one C-C double bond. According to the invention, the hydrogenation of the compound to be hydrogenated is carried out using a hydrogenation catalyst in an aqueous solution with a triblock copolymer that serves as a micelle former. The activity is increased under these conditions. In the event of an asymmetrical hydrogenation, the enantioselectivity is elevated. In a preferred embodiment, the inventive method is carried out in a membrane reactor which is equipped with a membrane on the discharge side. Said membrane is permeable to the product and is impermeable to the catalyst and the triblock copolymer.
