摘要:
An organobismuth derivative represented by general formula (I), a salt thereof, and a contrast medium containing the same as the active ingredient: wherein, X represents Y NR R , wherein Y represents -SO2- or -C(O)-, R represents C3-6 alkyl having 2 to 5 hydroxyl groups, R represents hydrogen, C1-6 alkyl optionally having 1 to 5 hydroxyl groups or C1-5 acyl, or R and R together may form C2-6 cycloalkylene optionally having 1 to 4 hydroxyl groups; X and X each independently represent hydrogen, C1-4 alkyl, C1-4 alkoxy, C1-4 alkylsulfonyl, C1-4 alkylcarbonyl, nitro or cyano, or has the same meaning as that of X ; and each of the above hydroxyl groups may be protected.
摘要(中):
一种由通式(I)表示的有机铋衍生物及其盐及含有其的活性成分的造影剂:其中X 1表示Y 1 NR 1 R 2,其中Y < 1表示-SO 2 - 或-C(O) - ,R 1表示具有2至5个羟基的C 3-6烷基,R 2表示氢,任选具有1至5个羟基的C 1-6烷基或C 1 -5酰基或R 1和R 2一起可以形成任选具有1至4个羟基的C 2-6亚环烷基; X 2和X 3各自独立地表示氢,C 1-4烷基,C 1-4烷氧基,C 1-4烷基磺酰基,C 1-4烷基羰基,硝基或氰基,或具有与X 1相同的含义。 ; 并且上述羟基中的每一个可以被保护。
