摘要:
4-Heterocyclyl-substituted dihydropyridines are prepared by reacting appropriate aldehydes with .beta.-keto esters and aminocrotonic acid esters, or by esterifying 4-heterocyclyl-substituted dihydropyridinecarboxylic acids. The 4-heterocyclyl-substituted dihydropyridines can be employed in medicaments, in particular for the treatment of disorders of the central nervous system.
摘要:
The present invention relates to the new compound rac-isopropyl 2-methoxyethyl 4-(2-chloro-3-cyano-phenyl)1,4 -dihydro-2,6-dimethylpyridine-3,5-dicarboxylate and its pure enantiomers, processes for their preparation and their use as medicaments, in particular for the treatment of cerebral and neuronal disorders, and a new intermediate for their preparation.
摘要:
4-Heterocyclophenyl-substituted dihydropyridines ##STR1## are prepared either by reacting suitable aldehydes with amino esters and .beta.-keto esters, or preparing the heterocyclic substituents of the 4-phenyl by cyclization of corresponding amidines or hydrazides, or esterifying dihydropyridinecarboxylic acids, which are already substituted by heterocyclic radicals, with corresponding alcohols. The 4-heterocyclophenyl-substituted dihydropyridines can be employed in medicaments, in particular for treatment of diseases of the central nervous system.
摘要:
Novel phenyl-substituted 1,4-dihydropyridines, prepared by reacting halogenophenyl-aldehydes with &bgr;-ketoesters, if appropriate with isolation of the ylidene compounds and enamines. The substances can be employed as active compounds in medicaments, in particular in cerebrally active compositions.
摘要:
4-Phenyl-3-substituted 1,4-dihydropyridine esters are prepared by reaction of benzaldehydes with ketoesters and enamines, if appropriate with isolation of the ylidene intermediate products, or by esterification of corresponding dihydropyridinecarboxylic acids with alcohols. The new 4-phenyl-3-substituted 1,4-dihydropyridine esters can be employed as active compounds in medicaments for the treatment of the central nervous system, in particular as cerebral therapeutics.
摘要:
The invention relates to new aryl-substituted alkoxycarbonyl-1,4-dihydropyridine-5-carboxylic acid esters, processes for their preparation and their use in medicaments, in particular as agents having a cerebral action.
摘要:
The present invention relates to novel animal feeds containing lanthanide compounds, as well as to the use of lanthanide compounds for reducing the digestibility of phosphorus contained in animal feeds.
摘要:
The invention relates to an aqueous suspension formulation comprising a coarsely particulate carbon adsorbent which is suitable for binding and eliminating harmful substances from the gastrointestinal tract, and a water-soluble or water-dispersible structure-forming agent and a humectant.
摘要:
An apparatus for securing a wheeled device such as a shopping cart to a vehicle is disclosed. The apparatus comprises a hook end and a ring end. The hook end is inserted into the wire mesh of the shopping cart. The hook end also has a terminal hook that prevents accidental release of the shopping cart. The ring end has a shape allowing it to either be looped over a towing ball attached to the vehicle, or inserted into the door lock mechanism of the vehicle.
摘要:
The invention relates to the use of substituted amines for the treatment and prevention of brain function disorders. The substituted amines are suitable on the basis of their properties as agonistic or antagonistic ligands for nicotinergic receptors, in particular for the treatment and prevention of senile and presenile dementia and dementia of the Alzheimer type, and of depressions.
