The invention concerns a thiazole derivative of the formula I
wherein Q is 2-oxo-1,2,3,4-tetrahydroquinolin-6-yl or 2-oxo-1,2-dihydroquinolin-6-yl which bears on the nitrogen atom at the 1-position a (1-4C)alkyl substituent;
X¹ is thio, sulphinyl or sulphonyl;
Ar is thiazolediyl;
R¹ is (1-4C)alkyl, (3-4C)alkenyl or (3-4C)alkynyl; and
R² and R³ together form a group of the formula -A²-X²-A³- which together with the carbon atom to which A² and A³ are attached define a ring having 5 or 6 ring atoms, wherein A² and A³, which may be the same or different, each is (1-3C)alkylene and X² is oxy, and which ring may bear one or two (1-4C)alkyl substituents;
or a pharmaceutically-acceptable salt thereof;
processes for their preparation; pharmaceutical compositions containing them and their use as 5-lipoxygenase inhibitors.
本发明涉及一种式 I 的噻唑衍生物
其中 Q 是 2-氧代-1,2,3,4-四氢喹啉-6-基或 2-氧代-1,2-二氢喹啉-6-基,其氮原子上 1 位有一个 (1-4C)烷基取代基;
X¹ 为硫代、亚砜基或磺酰基;
Ar 是噻唑二基;
R¹ 是(1-4C)烷基、(3-4C)烯基或(3-4C)炔基;以及
R² 和 R³ 共同形成一个式 -A²-X²-A³- 的基团,该基团与 A² 和 A³ 所连接的碳原子一起定义了一个具有 5 或 6 个环原子的环,其中 A² 和 A³ 可以相同或不同,各自为 (1-3C) 亚烷基,X² 为氧基,该环可以带有一个或两个 (1-4C) 烷基取代基;
或其药学上可接受的盐;
它们的制备工艺;含有它们的药物组合物及其作为 5-脂氧合酶抑制剂的用途。
