    • A tris(substituted phenyl)bismuth derivative represented by general formula (I) and, if any, a pharmaceutically acceptable salt thereof, wherein X represents Y -NR R [wherein Y represents -SO2- or -C(=O)-; and R and R represent each independently hydrogen, C1-C4 alkyl or A-Z (wherein A represents alkylene which has 2-6 carbon atoms in total and may have a branch having at least two carbon atoms, and Z represents OR (wherein R represents SiR R R (wherein R , R and R represent each independently C1-C4 alkyl or phenyl), hydrogen or C1-C4 alkyl) or NR R (wherein R and R represent each independently hydrogen or C1-C4 alkyl)), provided the case where R and R are both hydrogen atoms is excepted], -O-CHR -OR (wherein R represents C1-C4 alkyl, and R is as defined above) or Y -A-Z [wherein Y represents O, -S(O)n- (wherein n represents an integer of 0 or 2) or -NR - (wherein R is as defined above), and A and Z are each as defined above]; and X and X represent each independently hydrogen or any substituent defined above with respect to X . This compound has an excellent performance as a radio-logical contrast medium and is useful as an X-ray contrast medium for injecting into a blood vessel, urinary tract, and so forth.
    • 由通式(I)表示的三(取代的苯基)铋衍生物和(如果有的话)其药学上可接受的盐,其中X 1表示Y 1 -NR 1 R 2 [其中Y 1 >表示-SO 2 - 或-C(= O) - ; 并且R 1和R 2各自独立地表示氢,C 1 -C 4烷基或AZ(其中A表示总共具有2-6个碳原子并且可具有至少两个碳原子的支链的亚烷基,Z表示 OR 3(其中R 3表示SiR 4 R 5 R 6(其中R 4,R 5和R 6各自独立地为C 1 -C 4烷基或苯基), 氢或C 1 -C 4烷基)或NR 7 R 8(其中R 7和R 8各自独立地表示氢或C 1 -C 4烷基)),条件是其中R 1和R 2, 2>均为氢原子除外],-O-CHR 7 -OR 9(其中R 9表示C 1 -C 4烷基,R 7如上定义)或Y 2 - AZ [其中Y 2表示O,-S(O)n - (其中n表示0或2的整数)或-NR 1 - (其中R 1如上所定义),A和 Z各自如上所定义); X 2和X 3各自独立地表示氢或相对于X 1定义的任何取代基。 该化合物作为无线电逻辑造影剂具有优异的性能,并且可用作用于注射到血管,尿道等中的X射线造影剂。
