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;
R1: 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, —CH2—, —CO—, —(CH2)m—CO—,
—CH(R2)—CO—, —(CH2)p—Y—(C(R3)(R4))q—CO—, —NH—CO— or
—N(R5)—CO—;
in the above-mentioned respective definitions of the X, the bonding arm described at the left end represents a bond with R1;
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 —SO2—;
R2: phenyl or lower alkyl;
R3, R4: each independently represents hydrogen atom or lower alkyl;
R5: lower alkyl;
provided that the ring portion of the group represented by R1 is neither naphthylidine nor partially saturated group thereof, and, when X is —CH2— or —CO—, R1 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Ca感受受体的激活化合物(CaSR激动剂)的用途,以及包含上述化合物作为有效成分的制药组合物等。式中符号的含义如下:Ar:可选取取代的芳基或可选取取代的杂环芳基,其中杂环的环部分是一种5-至6-成员的单环杂环,它包含1或2个杂原子,并与苯环融合;R1:选自可选取取代的环烃基团和可选取取代的杂环基团的群;n:为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,左端所述的键臂表示与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:苯基或低碳基;R3,R4:各自独立地表示氢原子或低碳基;R5:低碳基;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,并且当X为—CH2—或—CO—时,R1不是萘基。
