The present invention relates to novel compounds of formula (I):
1
in which:
R
1
, R
2
and R
3
, which are identical or different, are each independently:
a (C
1
-C
6
)alkyl group,
a pyridinyl group or
a group —CH
2
—NR
4
R
5
, in which R
4
and R
5
are each independently a hydrogen atom or a (C
1
-C
4
)alkyl group, or alternatively R
4
and R
5
form, with the nitrogen atom to which they are bonded, a pyrrolidinyl, piperidinyl, hexahydroazepinyl, morpholinyl or piperazinyl group,
with the proviso that at least one of the substituents R
1
, R
2
and R
3
is other than a (C
1
-C
6
)alkyl group,
and their salts, solvates and hydrates, especially those which are pharmaceutically acceptable.
These compounds are useful particularly for the treatment of disorders of the venous circulation.
本发明涉及式(I)的新化合物:1其中:R1、R2和R3相同或不同,每个独立地为:(C1-C6)烷基、吡啶基或基团—CH2—NR4R5,其中R4和R5分别独立地为氢原子或(C1-C4)烷基,或者R4和R5与它们连接的氮原子形成吡咯烷基、哌嗪烷基、六氢-氮杂环己基、吗啉基或哌嗪基团,但至少有一个取代基R1、R2和R3不是(C1-C6)烷基,以及它们的盐、溶剂化合物和水合物,特别是那些在药学上可接受的。这些化合物特别适用于治疗静脉循环障碍。
