The present invention relates to an arylalkylamine compound represented by the following formula [I] or a pharmaceutically acceptable salt thereof, a process for preparing the same, and use of the above-mentioned compound as an activating compound (CaSR agonist) of a Ca sensing receptor, a pharmaceutical composition containing the above-mentioned compound as an effective ingredient, etc.
The symbols in the formula represent the following meanings:
Ar: optionally substituted aryl or
optionally substituted heteroaryl
here, the cyclic portion of the heteroaryl is bicyclic heterocyclic ring in which 5- to 6-membered monocyclic heterocyclic ring containing 1 or 2 hetero atom(s) and benzene ring are fused;
R
1
: a group selected from the group consisting of
optionally substituted cyclic hydrocarbon group, and
optionally substituted heterocyclic group;
n: an integer of 1 to 3;
X: single bonding arm, —CH
2
—, —CO—, —(CH
2
)
m
—CO—, —CH(R
2
)—CO—, —(CH
2
)
p
—Y—(C(R
3
)(R
4
))
q
—CO—, —NH—CO— or —N(R
5
)—CO—;
in the above-mentioned respective definitions of the X, the bonding arm described at the left end represents a bond with R
1
;
m is an integer of 1 to 3;
p is an integer of 0 to 2;
q is an integer of 0 to 2;
Y: —O— or —SO
1
—;
R
2
: phenyl or lower alkyl;
R
3
, R
4
: each independently represents hydrogen atom or lower alkyl;
R
5
: lower alkyl;
provided that the ring portion of the group represented by R
1
is neither naphthylidine nor partially saturated group thereof, and, when X is —CH
2
— or —CO—, R
1
is not naphthyl.
本发明涉及一种由以下式[I]表示的芳基烷基胺化合物或其药学上可接受的盐,其制备方法以及上述化合物作为钙感受受体的激活化合物(CaSR激动剂)的用途,含有上述化合物作为有效成分的制药组合物等。式中符号表示以下含义:Ar:可选取取代芳基或可选取取代杂环芳基;此处,杂环的环状部分是一个二环杂环环,其中包含1或2个杂原子的5-6元单环杂环和苯环融合在一起;R1:选自以下群组的群组,即可选取取代的环烃基团和可选取取代的杂环基团;n:1至3的整数;X:单键臂,-CH2-,-CO-,-(CH2)m-CO-,-CH(R2)-CO-,-(CH2)p-Y-(C(R3)(R4))q-CO-,-NH-CO-或-N(R5)-CO-;在上述各定义中,左端所描述的键合臂表示与R1键合;m为1至3的整数;p为0至2的整数;q为0至2的整数;Y:-O-或-SO1-;R2:苯基或低碳基;R3,R4:各自独立地表示氢原子或低碳基;R5:低碳基;前提是所述R1所表示的基的环状部分既不是萘亚甲基基团,也不是其部分饱和基团,且当X为-CH2-或-CO-时,R1不是萘基。
