摘要:
The present invention relates to a novel process for preparing O-(3-amino-2-hydroxy-propyl)-hydroxymic acid halides of formula (I) by reacting a carboxamide oxime of formula (II) wherein R is as specified above with reactive 3-amino-2-hydroxy-propane derivative, diazotizing the O-substituted carboxamide oxime thus obtained with sodium nitrite in the presence of hydrogen halide, decomposing the diazonium salt and if desired, separating the optically active enantiomers and/or reacting the resulting base with an organic or mineral acid, wherein the carboxamide oxime of formula (II) is reacted with a 3-hydroxy azetidinium salt of formula (III) wherein R and R are as defined above and Y is a salt forming anion, in a lower alcoholic, preferably ethanolic medium optionally containing water and made alkaline with an alkali hydroxide, and before diazotizing the O-substituted carboxamide oxime intermediate obtained, the reaction mixture is neutralised and the organic solvent is removed. The process according to the invention provides the compounds of formula (I) with a higher yield compared to the prior art processes.

The invention relates to hydroximic acid halogenides of the formula (I) wherein the substituents have the following significance; X - NOCH3, CHOCH3 or CHCH3; Y - O or NH; R - halogen; R - optionally substituted alkyl, alkenyl, alkynyl, cycloalkyl or aryl; R - optionally substituted alkyl, alkoxyalkyl, cycloalkyl-alkyl, alkenyl and alkynyl and their salts. The invention also relates to a method for the production and use of said hydroximic acid halogenides.
摘要:
A method of increasing expression of a molecular chaperon by a cell and/or enhancing the activity of a molecular chaperon in cells is provided. The method comprises treating a cell that is exposed to a physiological stress which induces expression of a molecular chaperon by the cell with an effective amount of a certain hydroxylamine derivative to increase the stress. Alternatively, a hydroxylamine derivative can be administrated to a cell before it is exposed to a physiological stress which induces expression of a molecular chaperon by the cell. Preferably, the cell to which a hydroxylamine derivative is administered is a eukaryotic cell. The hydroxylamine derivative corresponds to the formulae (I) or (II). The invention also provides novel hydroxylamine derivatives falling within the scope of the formulae (I) and (II) as well as pharmaceutical and/or cosmetical compositions comprising the said compounds.

摘要:
The invention relates to novel compounds of formula (I), wherein X means halogen; Z stands for an aromatic group, pyridinyl group or the like; and R represents an alkyl or phenylalkyl group or an -A-N(R1)R2 group, and in the latter R1 and R2 stand, independently from each other, for hydrogen or alkyl group; or R1 and R2, together with the adjacent nitrogen atom, form a 5- to 7-membered, saturated heterocyclic group optionally containing an additional nitrogen, oxygen or sulfur atom, said heterocyclic group optionally being substituted by at least one alkyl group; and A stands for a straight or branched chain alkylene group, as well as the pharmaceutically acceptable acid addition salts thereof; furthermore, to processes for the preparation of the above novel compounds, and pharmaceutical compositions containing these compounds or their pharmaceutically acceptable acid addition salts as active ingredients. Further, the invention relates to certain novel intermediates of formula (II). The compounds of formula (I) possess anti-ischaemic effect and therefore, they are useful for treating ischaemic states and diseases, e.g. myocardial ischaemia (induced e.g. by occlusion of the coronary arteries).
