The invention concerns acetanilide derivatives of the formula I
wherein R⁴ is (1-4C)alkyl;
R⁵ is hydrogen or (1-4C)alkyl;
Ar¹ is phenylene, pyridinediyl or pyrimidinediyl;
A¹ is a direct link to X¹ or A¹ is (1-4C)alkylene;
X¹ is oxy, thio, sulphinyl or sulphonyl;
Ar² is thiophenediyl, furandiyl, thiazolediyl, oxazolediyl, thiadiazolediyl or oxadiazolediyl;
R¹ and R² together form a group of the formula -A²-X²-A³- which together with the oxygen atom to which A² is attached and with the carbon atom to which A³ is attached define a ring having 5 or 6 ring atoms, wherein each of A² and A³ is (1-3C)alkylene and X² is oxy, thio, sulphinyl or sulphonyl and which ring may bear one, two or three (1-4C)alkyl substituents; and
R³ is (1-4C)alkyl;
or pharmaceutically-acceptable salts thereof;
processes for their manufacture; pharmaceutical compositions containing them and their use as 5-lipoxygenase inhibitors.
该发明涉及具有以下式I的乙酰苯胺衍生物,其中R⁴是(1-4C)烷基;R⁵是氢或(1-4C)烷基;Ar¹是苯基、吡啶二基或嘧啶二基;A¹是直接连接到X¹的链或A¹是(1-4C)烷基;X¹是氧、硫、亚砜基或砜基;Ar²是噻吩二基、呋喃二基、噻唑二基、噁唑二基、噻二唑二基或噁二唑二基;R¹和R²一起形成一个具有5或6个环原子的环的基团,其中A²和A³各自是(1-3C)烷基,X²是氧、硫、亚砜基或砜基,该环可能具有一个、两个或三个(1-4C)烷基取代基;R³是(1-4C)烷基;或其药用可接受盐;其制备方法;含有它们的药物组合物以及它们作为5-脂氧合酶抑制剂的用途。
