The present invention relates to a compound of formula I,
wherein
R
1
is selected from the group consisting of hydrogen and lower alkyl;
each R
2
is independently selected from the group consisting of hydrogen and lower alkyl;
each R
3
is independently selected from the group consisting of hydrogen, lower alkyl, lower alkoxy, phenyloxy, benzyloxy, halogen and lower alkyl substituted by halogen;
R
4
is selected from the group consisting of hydrogen and lower alkyl;
X is selected from the group consisting of —CH
2
—, —CH— and —O—;
Y is selected from the group consisting of —CH
2
—, —CH
2
CH
2
—, —CH— and a bond; with the proviso that, when X is —O—, Y is —CH
2
—;
Z is selected from the group consisting of —CH
2
— and —CH—;
m is 1 or 2; and
n is 1 or 2.
The invention relates also to a pharmaceutically-acceptable acid-addition salt of such a compound, methods for making the compound, and a composition comprising such a compound.
It has been found that the compounds of formula I have a good affinity to the trace amine associated receptors (TAARs), especially for TAAR1.
本发明涉及一种化合物式I,其中R1选自氢和低碳基的群组;每个R2独立地选自氢和低碳基的群组;每个R3独立地选自氢、低碳基、低烷氧基、苯氧基、苄氧基、卤素和被卤素取代的低碳基的群组;R4选自氢和低碳基的群组;X选自—
CH2—、—CH—和—O—的群组;Y选自— —、— —、—CH—和键的群组;但当X为—O—时,Y为— —;Z选自— —和—CH—的群组;m为1或2;n为1或2。本发明还涉及该化合物的药学可接受的酸加成盐、制备该化合物的方法和包含该化合物的组合物。已经发现,式I化合物对痕量胺相关受体(
TAARs)具有良好的亲和力,特别是对
TAAR1。
