摘要:
4-(1''-ALKYL-5''-NITROIMIDAZOLYL-2''-METHYLENE-IMINO)-TETRAHYDRO1,4-THIAZINE 1,1-DIOXIDES OF THE FORMULA
IN WHICH R1 is hydrogen, methyl, ethyl, or 2-hydroxy-ethyl and R2 is hydrogen, methyl, ethyl or methoxymethyl, are prepared by reaction of 1-alkyl-5-nitroimidazolyl-2-aldehyde or a functional derivative thereof with 4-amino-tetrahydro-1,4-thiazine 1,1dioxide. The products of the invention are suitable for the treatment of protozoal diseases.
摘要:
Pyrolysis of 2-diazo-4,5-dicyano-2H-imidazole in the presence of certain halohydrocarbons yields 1-hydrocarbon substituted-2-halo4,5-dicyanoimidazoles. Pyrolysis of the same starting material in the presence of hydrocarbons, certain other halohydrocarbons, or certain Group I metal salts, yields 2-substituted-4,5-dicyanoimidazoles.
摘要:
The production of imidazoles bearing a substituent on a nitrogen atom by reaction of an imidazole with an aliphatic alcohol or ether in the presence of an oxide and/or phosphate of a metal of Group 2, 3 or 4 of the Periodic Table and additionally in the presence of a phosphoric acid and/or an ester of a phosphoric acid. The products are intermediates for the production of dyes, textile auxiliaries and insecticides.
摘要:
THIS INVENTION RELATES TO 1-(DIMESITYLMETHYL) IMIDAZOLE AND ITS ACID ADDITION AND QUATERNARY AMMONIUM SALTS AND TO A PROCESS FOR ITS PREPARATION. IN ADDITION, TO PHARMACEUTICAL COMPOSITIONS CONSISTING SAID COMPOUNDS AND METHODS FOR USING SAID COMPOSITIONS AS ANTI-FUNGAL AGENTS AND IN THE TREATMENT OF INFECTIONS CAUSED BY MYCOPLASMA GALLISEPTICUM.
摘要:
THE INVENTION RELATES TO A NOVEL DERIVATIVE OF HISTIDINE OF FORMULA:
N-(CYCLOPENTYL-CO-HIS-)-PYRROLIDINE
IN WHICH HIS L-HISTIDYL, AND ITS PHAARMACEUTICALLY ACCEPTABLE SALTS. THE NOVEL COMPOUND AND ITS SALTS WITH PHARMACEUTICALLY ACCEPTABLE ACIDS ARE USEFUL BECAUSE OF THEIR INHIBITING ACTION ON THE HYPOTHALAMIC THYROTROPIN RELEASING HORMONE (TRH).
