摘要:
The present invention relates to N-substituted 2-hydroxybenzamide and N-substituted 2-hydroxy-α-oxo-benezene acetamide having the formula wherein y one or two is R₁ and R₅ represent a hydrogen atom or a substituent b is zero to four and R₆ is an alkyl group having 6 to 20 carbon atoms, an eventually substituted aryl or aralkyl group or a group CH=CHR₄ or (CH₂) n -CO-R₄ in which R₄ represents an eventually substituted phenyl group. These compounds are usefull for the treatment of diseases in which products having lipoxygenase enzyme activity contribute to the pathological condition. Selected novel intermediates are also the present invention.

摘要:
Anticholinergic 3-[2-(azabicyclo)ethyl)-1,2,3,4-tetra- hydro-5H-[1]benzopyrano[3,4-c]pyridin-5-ones, useful for treating broncho-spastic diseases in mammals, are disclosed. Also disclosed are methods for preparing such novel compounds, and pharmaceutical compositions containing them. The novel compounds have the formula I: wherein R 1 is a hydrogen atom, an alkyl radical having from 1 to 6 carbon atoms, an alkoxy radical having from 1 to 6 carbon atoms, or a hydroxy, nitro, halo, amino or acylamino radical; R 2 is a hydrogen atom, a hydroxy radical, an alkyl radical having from 1 to 6 carbon atoms, an alkoxy radical having from 1 to 6 carbon atoms or a phenyl radical; R 3 is a hydrogen atom or an alkoxy radical having from 1 to 6 carbon atoms; or R 1 and R 2 taken together are -OCH 2 0-; or R 2 and R 3 taken together are -CH=CH-CH=CH-; and or a pharmaceutically acceptable salt thereof, provided that R 1 is not hydroxy when R 2 is -OC 2 H 5 and X is
