Mitomycin derivatives containing substituted dithioethylamino groups at the 7th position are provided. The mitomycin derivatives according to the present invention are superior to mitomycin C with respect to their improved anti-tumour activity and toxicity. More particularly, they exhibit a wider tolerance of dosage against Sarcoma 180A solid tumour as well as a better survival time and weaker bone marrow supression against P388. Furthermore, certain compounds exhibit a high water-solubility which is advantageous for pharmaceutical purposes. Excellent anti-tumour agents may readily be prepared by using the derivatives of the present invention.
本发明提供了在第7位含有取代二硫乙基氨基基团的丝裂霉素衍生物。与丝裂霉素C相比,本发明的丝裂霉素衍生物具有改进的抗肿瘤活性和毒性。特别地,它们对Sarcoma 180A实体瘤的剂量耐受性更广,对P388的骨髓抑制更弱,且某些化合物表现出高水溶性,这对制药目的是有利的。通过使用本发明的衍生物,可以轻松地制备出优良的抗肿瘤剂。
