A subject-matter of the invention are oxaindene derivatives of general formula
wherein
R1represents a C1-4-alkyl, C1-4-alkoxy or C3-6-cycloalkyl group,
R2stands for hydrogen or a C1-4-alkyl or C3-6-cycloalkyl group,
R3represents hydrogen or a C1-4-alkyl, C1-4-alkoxy or benzyloxy group,
Xmeans hydrogen, an aliphatic C1-4-acyl or benzoyl or naphthoyl group, optionally substituted by 1 or more nitro or C1-4-alkoxy group(s) or a group of formula
in which latter
R7stands for a C1-4-alkylene group
and
R5 and R6each represents a C1-4-alkyl group
or
R5 and R6together with the nitrogen atom to which they are attached form a piperidyl or morpholinyl group,
A and Btogether form an ethylene or a vinylene group
and
nis 1, 2 or 3,
and their stereoisomers and their mixtures as well as acid addition salts of these compounds.
Moreover there are provided for a process for preparing these compounds, medicaments containing them and the use of these compounds.
They have a strong 5-lipoxygenase enzyme inhibiting activity.
本发明的主题是一种一般公式的氧吲哚衍生物,其中R1代表C1-4-烷基、C1-4-烷氧基或C3-6-环烷基,R2代表氢或C1-4-烷基或C3-6-环烷基,R3代表氢或C1-4-烷基、C1-4-烷氧基或苄氧基,X代表氢、脂肪族C1-4-酰基或苯甲酰基或萘甲酰基,可选择地被1个或多个硝基或C1-4-烷氧基取代,或者是一个公式中的基团,其中R7代表C1-4-烷基烯基,R5和R6各自代表C1-4-烷基基团,或者R5和R6与它们连接的氮原子一起形成哌啶基或吗啡啉基,A和B一起形成乙烯或乙烯基基团,n为1、2或3,以及它们的立体异构体和它们的混合物,以及这些化合物的酸盐。此外还提供了一种制备这些化合物的方法,包含它们的药物以及这些化合物的用途。它们具有强大的5-脂氧酶酶抑制活性。
