There are provided s-phenyltris (sulfonylimino) tri- benzene mono- and di-sulfonic acids and their salts which are useful as complement inhibitors. The novel compounds have the general formula:
wherein each R is selected from the group consisting of hydrogen and alkali metal; each R1, R2 and R3 is selected from the group consisting of hydrogen and SO3A, wherein A is selected from the group consisting of hydrogen and a pharmaceutically acceptable salt cation; provided that at least one of the R1, R2 and R3 groups on each phenyl is SO3A; and further provided that when R2 is SO3A. R1 and R, may not be SO3A. E.g., these compounds may be prepared according to the following flowchart:
wherein R' stands for
These compounds find utility as complement inhibitors in body fluids and as such may be used to ameliorate or prevent those pathological reactions requiring the function of complement and in the therapeutic treatment of warm-blooded animals having immunologic diseases.
本发明提供了可用作补体
