Abstract

The present invention provides an application of levomorpholinonidazol [R-(-)-1-(2-methyl-5nitroimidazole-1-group)-morpholinylpropane-2-alcohol] or its medicinal salt in preparation of medicine for resisting amoebic infection and resisting vaginal trichomonad infection.

Description

technical field [0001] The present invention relates to L-morpholinidazole [R-(-)-1-(2-methyl-5-nitroimidazol-1-yl)-3-morpholinopropan-2-ol] or its medicinal salt The new application of the invention is the application in the preparation of anti-parasitic infection drugs. Background technique [0002] Levomorphinidazole is R-(-)-1-(2-methyl-5-nitroimidazol-1-yl)-3-morpholinopropan-2-ol. 2-Methyl-5-nitazole imidazole derivatives have good anti-anaerobe activity, and many preparation methods have been disclosed. The Chinese patent application whose publication number is CN1605586A discloses α-substituted 2-methyl-5-nitroimidazole-1-ethanol derivatives and their preparation methods and uses, but for α-substituted 2-methyl-5- The optical activity of the nitroimidazole-1-ethanol derivatives has not been elucidated. Levomorphinidazole has no relevant reports at present. Contents of the invention [0003] The object of the present invention is to provide L-morpholinidazole [R...
