A tris(substituted phenyl)bismuth derivative of the general formula (I) or, if any, a pharmaceutically acceptable salt thereof:
wherein X¹ is Y¹-NR¹R²[wherein Y¹ is -SO₂- or
and each of R¹ and R² is, independently of each other, a hydrogen atom, a C₁₋₄ alkyl group or A-Z (wherein A is an alkylene chain which has 2-6 carbon atoms in total and may have a branch having at least two carbon atoms, and Z is OR³ (wherein R³ is SiR⁴R⁵R⁶ (wherein each of R⁴, R⁵ and R⁶ is, independently of one another, a C₁₋₄ alkyl group or a phenyl group), a hydrogen atom or a C₁₋₄ alkyl group) or NR⁷R⁸ (wherein each of R⁷ and R⁸ is, independently of each other, a hydrogen atom or a C₁₋₄ alkyl group)) provided that the case where R¹ and R² are both hydrogen atoms is excepted],
(wherein R⁹ is a C₁₋₄ alkyl group, and R⁷ is the same as defined above) or Y²-A-Z [wherein Y² is an oxygen atom, - S(O)n- (wherein n is an integer of 0 or 2) or
(wherein R¹ is the same as defined above), and A and Z are the same as defined above], and
each of X² and X³ is, independently of each other, a hydrogen atom or any substituent defined above with respect to X¹}.
通式(I)的三(取代苯基)铋衍生物或(如有)其药学上可接受的盐:
其中 X¹ 是 Y¹-NR¹R²[其中 Y¹ 是 -SO₂- 或
且 R¹ 和 R² 各自独立地为氢原子、C₁₋₄ 烷基或 A-Z(其中 A 为烯链,总共有 2-6 个碳原子,并可能有一个至少有两个碳原子的分支、和 Z 是 OR³(其中 R³ 是 SiR⁴R⁵R⁶(其中 R⁴、R⁵ 和 R⁶ 各自是、相互独立的 C₁₋₄烷基或苯基)、氢原子或 C₁₋₄ 烷基)或 NR⁷R⁸(其中 R⁷ 和 R⁸ 各自是、其中 R⁷ 和 R⁸ 各自独立地为氢原子或 C₁₋₄ 烷基)),但 R¹ 和 R² 均为氢原子的情况除外]、
(其中 R𠞙 是 C₁₋₄烷基,而 R⁷ 与上述定义相同)或 Y²-A-Z [其中 Y² 是氧原子、- S(O)n-(其中 n 是 0 或 2 的整数)或 Y²-A-Z]。
(其中 R¹ 与上文所定义的相同),且 A 和 Z 与上文所定义的相同],且
X² 和 X³ 各自独立地为氢原子或上文就 X¹ 所定义的任何取代基}。
