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
2
—;
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.
本发明涉及一种由下式[I]表示的芳基烷基胺化合物或其药学上可接受的盐,制备该化合物的方法,以及上述化合物作为钙感受受体(CaSR激动剂)的激活化合物、包含上述化合物作为有效成分的药物组合物等的用途。式中符号表示以下含义:Ar:可选取的取代芳基或可选取的取代杂环芳基,在此,所述杂环的环状部分是由1或2个杂原子的5-6元单环杂环与苯环融合而成的双环杂环;R1:选自可选取的取代环烃基团和可选取的取代杂环基团的群;n:为1至3的整数;X:单键连接臂,-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X的各自定义中,左端所述连接臂表示与R1的键合;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-SO2-;R2:苯基或低碳烷基;R3,R4:各自独立地表示氢原子或低碳烷基;R5:低碳烷基;所述R1表示的基的环部分既不是萘亚甲基基团,也不是其部分饱和基团,当X为-CH2-或-CO-时,R1不是萘基。
