Mitomycin compounds of the general formula (I): ##STR1## wherein X is selected from an alkoxy group having 1 to 4 carbon atoms and amino group; and Z is selected from --OH, --OCONH.sub.2 and --OCO.sub.2 C.sub.6 H.sub.5 groups. The compounds of this formula may be used as starting materials for the preparation of various mitomycin compounds. When X is as hereinbefore defined and Z is --OCONH.sub.2, the compounds exhibit antibacterial activity and are of potential interest as medicaments. Preferred examples of the compounds are 9-Epi-mitomycin B and 9-epi-mitomycin D. The compounds of the formula (I) may be obtained from known mitomycin B or mitomycin D.
通式(I)的丝裂霉素化合物:##STR1## 其中X选自具有1到4个碳原子的烷氧基和氨基;Z选自--OH,--OCONH.sub.2和--OCO.sub.2 C.sub.6 H.sub.5基团。该式化合物可用作制备各种丝裂霉素化合物的起始材料。当X按前述定义,Z为--OCONH.sub.2时,该化合物表现出抗菌活性,具有潜在的药用价值。该化合物的首选示例为9-Epi-丝裂霉素B和9-epi-丝裂霉素D。式(I)的化合物可从已知的丝裂霉素B或丝裂霉素D中获得。
