摘要:
The invention relates to a novel process of amalodipine benzenesulphonate of formula (I) by reacting a new 2-[/2-carboxy-benzoyl)-aminoethoxy/methyl/]-4-(2-chlorophenyl)-3-ethoxycarbonyl-5-methoxycarbonyl-6-methyl-1,4-di-hydropyridine derivative of general formula (II) wherein X represents hydrogen or alkali metal or alkali earth metal or quaternary ammonium—with benzenesulphonic acid.
摘要:
The present invention relates to novel compounds of the general formula (I), ##STR1## wherein R stands for hydrogen, halogen, C.sub.1-4 alkyl, C.sub.1-4 alkoxy or a C.sub.1-4 acylamino group; andR.sup.1 is hydrogen or a carboxyl-protective group or E and/or Z configuration as well as their salts.The compounds according to the invention show a cytoprotecive effect and in addition, a valuable anti-inflammatory action. Their toxicity is low.
摘要:
The present invention relates to new compounds of formula (I), (I) wherein the meaning of R1 is hydrogen atom, C1-C5 acyl group, benzoyl group or R2—COOR3 group, Y is hydrogen atom or alkali ion, R2 is C1-C4 straight or branched alkylidene group and R3 is hydrogen atom, C1-C4 alkyl group or alkali ion, and/or stereoisomers and/or diastereomers and/or pharmaceutically acceptable salts and/or hydrates and/or solvates thereof, which are suitable for the treatment of pain of acute and chronic inflammation origin as well as postoperative pain and dysmenorrhea. The invention also relates to the process of the synthesis of compounds of formula (I) as well as the pharmaceutical composition containing the same and the use for treatment of pain, inflammation and disorders associated with inflammation.

The invention relates to a novel process for the preparation of 1-[3-mercapto-(2S)-methylpropionyl]-pyrrolidine-(2S)-carboxylic acid through the N-acylation of L-proline.According to the process of the invention L-proline is acylated with a 3-halogen-2-methylpropionyl chloride of the formula III ##STR1## wherein Hal is a halogen atom, preferably chlorine or bromine, the obtained 1-[3-halogen-(2S)-methylpropionyl]-pyrrolidine-(2S)-carboxylic acid, wherein Hal is as stated above, is reacted with an alkali thiosulfate or alkali trithiocarbonate and the reaction product is hydrolized with an acid.The process of the invention is very economical as compared with the known processes. The desired product is prepared from methacrylic acid in 4 reaction steps with a total yield of 25 percent and from L-proline in 2 reaction steps with a total yield of 30 percent.
摘要:
Keys which are used in a keyboard of a miniaturized data processing device include an upper surface which is provided with a downwardly-extending wall running transversely to the movement of the finger when operating the keys. The downwardly-extending wall, which is formed, for example, by a groove disposed in the upper surface, serves as a support for the tip of a user's fingernail when operating the keys. Such keys make possible an accurate operation even if the keys are disposed closely side by side in a miniaturized key board and the fingernail is fashionably long.
