NEW PYRIDINE DERIVATIVES AS LEUKCOTRIENE B4 ANTAGONISTS
The invention pertains to new pyridine derivatives of formula (I) where . . . denotes a single bond or a double bond, m, n, p and r in each case stands for a number from 0 to 5, q is 1 or 2, U denotes a single bond or the grouping -CH2-CH2-, -CHOH-, -CO- -CH=CH-, -C=C-, -CO-CO- or -CHOH-CHOH-, V stands for a single bond, phenyl residue or pyridyle residue, W is a hydrogen atom, a halogen atom, an alkyl group with up to four carbon atoms, a trifluoromethyl group, an alkylsulfonylamino group, a trifluoromethylsulfonylamino group, an arylsulfonylaminocarbonyl group, a free, esterified or amidated carboxyl group, or a hydroxy group, X denotes a free, esterified or amidated carboxyl group, Y is an oxygen atom or a methylene group, and Z is a single bond if q is 2 or otherwise an alkyl group or alkylene group with at most 8 carbon atoms or a phenyl, phenoxy or styryl residue substituted by alkyl groups with at most 4 carbon atoms, alkoxy groups with at most 4 carbon atoms, 1-oxoalkyl groups with at most 4 carbon atoms, halogen atoms and/or trifluoromethyl groups. The invention also concerns salts of these derivatives with bases which are generally recognized as physiologically safe.
