The present invention is concerned with 2-oxo-2,3-dihydro-indoles of general formula
wherein
is phenyl or a heteroaryl group, selected from pyridinyl, pyrimidinyl, imidazolyl, isoxazolyl or pyrazolyl;
is phenyl or pyridinyl, wherein the N atom in the pyridinyl group may be on all free positions;
R
1
is hydrogen, lower alkyl, lower alkyl substituted by halogen, lower alkoxy or halogen;
n is 1 or 2; if n is 2, R
1
may be the same or not;
R
2
/R
2′
are independently from each other lower alkyl, or form together with the carbon atom to which they are attached a C
3-6
-cycloalkyl ring;
R
3
is lower alkyl, C
3-6
-cycloalkyl, CH
2
—C
3-6
-cycloalkyl, C
3-6
-cycloalkyl wherein one ring-carbon atom is replaced by —O—, (CH
2
)
3
—O—C
3-6
-cycloalkyl, lower alkyl substituted by hydroxy, lower alkyl substituted by halogen, (CH
2
)
3
—S(O)
2
—C
3-6
-cycloalkyl or (CH
2
)
2
—S(O)
2
-lower alkyl;
R
4
is hydrogen, halogen or lower alkyl;
m is 1 or 2; if m is 2, R
4
may be the same or not;
as well as with a pharmaceutically acceptable salts thereof, with a racemic mixture, or with its corresponding enantiomer and/or optical isomer and/or stereoisomer thereof.
本发明涉及一般式的2-氧代-2,3-二氢吲哚:
其中
R1为氢、较低的烷基、被卤素取代的较低的烷基、较低的烷氧基或卤素;
n为1或2;如果n为2,则R1可以相同也可以不同;
R2/R2′互相独立,为较低的烷基,或与它们所附着的碳原子一起形成C3-6环烷基环;
R3为较低的烷基、C3-6环烷基、CH2—C3-6环烷基、C3-6环烷基,其中一个环碳原子被—O—取代,(CH2)3—O—C3-6环烷基、被羟基取代的较低的烷基、被卤素取代的较低的烷基、(CH2)3—S(O)2—C3-6环烷基或(CH2)2—S(O)2-较低的烷基;
R4为氢、卤素或较低的烷基;
m为1或2;如果m为2,则R4可以相同也可以不同;
以及其药学上可接受的盐、其外消旋混合物、其对应的对映体和/或光学异构体和/或立体异构体。
