Problems to be solved are to provide novel low-molecular compounds which exhibit calcium receptor antagonist activity, and which are highly safe and orally administrable. As a means for solving the problems, compounds having the Formula (I) or pharmaceutically acceptable salts thereof are provided.
[in the formula, the substituent groups are defined as follows. R1 and R2a, R2b : a hydrogen atom, etc. R3: a methyl group, an ethyl group, etc. Z: a carboxy group, etc. Ar: a phenyl group, etc. A: a single bond, etc. B: a single bond, etc. n: 0 or 1. m: an integer of 0 to 6.]
有待解决的问题是提供新型低分子化合物,这些化合物具有钙受体拮抗剂活性,且安全性高、可口服。为了解决这些问题,我们提供了具有式(I)的化合物或其药学上可接受的盐类。
[式中,取代基团定义如下。R1 和 R2a、R2b:氢原子等。R3:甲基、乙基等。Z:羧基等Ar:苯基等。A:单键等B:单键等 n:0 或 1 m:0 至 6 的整数]。
