Compounds of the formula:
wherein X is alkylene or-(CR6-CR7)r- wherein R6 is H, alkyl or phenyl, R7 is H, alkyl, cyano or phenyl, and r is 1 or 2; A is alkylene or alkylene interrupted by at least one double bond;
R1 is H, halogen, alkyl, alkoxy, alkylthio, cycloalkyloxy, cycloa-Ikylthio, alkoxycarbonyl, carboxy, phenyl, phenoxy, phenylthio, 3-pyridyloxy or 3-pyridylthio; R2 is H, hydroxy, alkanoyloxy or alkoxycarbonyloxy, or adjacent R, and R2 may combine to form tetramethylene or-CH2OCR8R9O-(R8 and Rg are alkyl); R3 is H, alkyl or hydroxyalkyl; R4 is H or alkyl; R5 is phenyl, heteroaryl or-(CH2)m-CHR10R11 (R10 is H or phenyl, R11
is phenyl or pyridyl and m is 0 to 2); p is 0 or 1; and q is 2 or 3; the phenyl group or moiety being optionally substituted, and salts thereof show excellent antiallergic activity mainly through 5-lipoxygenase inhibiting activity, antihistamine activity and/or inhibitory activity against chemical mediator release and are useful for treatment of allergic diseases. Processes for their preparation and pharmaceutical compositions containing them are also described.
式中的化合物:
其中 X 是亚烷基或-(CR6-CR7)r- 其中 R6 是 H、烷基或苯基,R7 是 H、烷基、氰基或苯基,r 是 1 或 2;A 是亚烷基或至少被一个双键打断的亚烷基;
R1 是 H、卤素、烷基、烷氧基、烷硫基、环烷氧基、环烷硫基、烷氧羰基、羧基、苯基、苯氧基、苯硫基、3-吡啶氧基或 3-吡啶硫基;R2 是 H、羟基、烷酰氧基或烷氧基羰基氧基,或相邻 R 和 R2 可结合形成四亚甲基或-CH2OCR8R9O-(R8 和 Rg 是烷基);R3 是 H、烷基或羟烷基;R4 是 H 或烷基;R5 是苯基、杂芳基或-(CH2)m-CHR10R11(R10 是 H 或苯基,R11
