摘要:
The optically pure forms of monocarbamates of halogenated 2-phenyl-1,2-ethanediol and dicarbamates of 2-phenyl-1,2-ethanediol have been found to be effective in the treatment of disorders of the central nervous system, especially as anti-convulsive or anti-epileptic agents.
摘要:
O-carbamoyl-(D/L )-phenylalaninol represented by structural formula I is pharmaceutically useful to treat diseases of the central nervous system, which is prepared by a characteristic process comprising the steps of: treating phenylalaninol with benzyl chloroformate in a basic aqueous solution medium, to give N-benzyloxycarbonyl-phenylalaninol; subjecting this intermediate to reaction with phosgene and then, to the treatment with excess of concentrated ammonium hydroxide aqueous solution, to provide O-carbamoyl-N-benzyloxycarbonyl-phenylalaninol; deprotecting it through hydrogenolysis reaction. ##STR1##
摘要:
The pure enantiomeric forms, as well as enantiomeric mixtures excluding the racemic mixture of monocarbamates of 2-phenyl-1,2-ethanediol substituted with more than one halogen atom on the phenyl ring and dicarbamates of 2-phenyl-1,2-ethanediol substituted with more than one halogen atom on the phenyl ring have been found to be effective in the treatment of disorders of the central nervous system.
摘要:
Provided are a process for the preparation of phenyl carbamate derivatives, useful in the treatment of CNS (central nervous system) disorders, an intermediate in the synthesis of the phenyl carbamate derivatives, and a process for preparation of the intermediate.
摘要:
The present invention is a method for the treatment of depression comprising administering to a subject in need thereof a therapeutically effective amount of one or more carbamate compounds of Formula 1 and/or Formula 2 as herein defined and shown below for the treatment of depression. The present invention is directed to a method for the treatment of depression, which includes mono-therapy and alternatively, co-therapy with at least one additional antidepressant.
摘要:
A novel method of vehicle modulated administration of an anticonvulsive agent to the mucous membranes of humans and animals is disclosed. The vehicle system is an aqueous pharmaceutical carrier comprising an aliphatic alcohol (10–80%) or a glycol (10–80%), and their combinations with a biological surfactant such as a bile salt or a lecithin. The pharmaceutical composition provides a means to control and promote the rate and extent of transmucosal permeation and absorption of the medicaments via a single and multiple administration. Nasal administration of the pharmaceutical preparation produces a high plasma concentration of the anticonvulsant nearly as fast as intravenous administration. Such compositions are particularly suitable for a prompt and timely medication of patients in the acute and/or emergency treatment of status epilepticus and other fever-induced seizures.
摘要:
This invention is directed to a method for preventing or treating bipolar disorder comprising administering to a subject in need thereof a therapeutically effective amount of an enantiomer of Formula (I) or enantiomeric mixture wherein one enantiomer of Formula (I) predominates: wherein phenyl is substituted at X with one to five halogen atoms selected from the group consisting of fluorine, chlorine, bromine and iodine; and, R1, R2, R3 and R4 are independently selected from the group consisting of hydrogen and C1–C4 alkyl; wherein C1–C4 alkyl is optionally substituted with phenyl (wherein phenyl is optionally substituted with substituents independently selected from the group consisting of halogen, C1–C4 alkyl, C1–C4 alkoxy, amino, nitro and cyano).
