The present invention concerns compounds of formula (I): wherein R
1
is selected from the group consisting of H, and optionally substituted C
1-6
alkyl, C
3-7
cycloalkyl, C
3-7
cycloalkyl-C
1-4
alkyl, and phenyl-C
1-4
alkyl; R
2
and R
3
are either: (i) independently selected from H, R, R′, SO
2
R, C(═O)R, (CH
2
)
n
NR
5
R
6
, where n is from 1 to 4 and R
5
and R
6
are independently selected from H and R, where R is optionally substituted C
1-4
alkyl group, and R′ is an optionally substituted phenyl-C
1-4
alkyl group, or (ii) together with the nitrogen atom to which they are attached, form an optionally substituted C
5-7
heterocyclic group; R
4
is an optionally substituted C
9-14
aryl group; their use as pharmaceuticals, in particular for treating conditions alleviated by antagonism of a 5-HT
2B
receptor.
本发明涉及公式(I)的化合物:其中R1选自H,及可选取的取代C1-6烷基,C3-7环烷基,C3-7环烷基-C1-4烷基和苯基-C1-4烷基;R2和R3是:(i)独立选自H,R,R',SO2R,C(═O)R,(CH2)nNR5R6,其中n为1至4,R5和R6独立选自H和R,其中R为可选取的取代C1-4烷基,R'为可选取的取代苯基-C1-4烷基,或(ii)与它们所连接的氮原子一起形成可选取的取代C5-7杂环基;R4为可选取的取代C9-14芳基基团;其用途为制成药物,特别是用于治疗通过5-HT2B受体拮抗缓解的疾病。
