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

)—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

—;
R
2
: phenyl or lower alkyl;
R

, 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公式[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),以及含有上述化合物作为有效成分的制药组合物等的用途。公式中的符号表示以下含义:Ar:此处为可选取代的芳基或可选取代的杂环芳基,其中杂环的环部分是一个含有1或2个杂原子的5-至6元单环杂环,与苯环融合;R1:选自可选取代的环烃基团和可选取代的杂环基团的群;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—;在上述各定义的X中,左端所描述的键臂表示与R1的键;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;前提是由R1表示的基团的环部分既不是萘亚甲基也不是其部分饱和基团,且当X为—CH2—或—CO—时,R1不是萘基。
