Mitomycln derivatives having a novel substituted dithio- ethylamlno group an 7-position. These compounds are better than mitomycin C with respect to an oncostatic activity and toxicity. Specifically, compounds showing a wider effective administration region against sarcoma 180A, a higher life prolonging effect gainst P$88, and a less marrow depressing effect are disclosed. Some of them have a high water solubitity which is advantageous in forming a pharmaceutical preparation, thus facilitating preparation of excellent oncostatic agents.
丝裂霉素衍生物具有新颖的 7 位取代二硫代乙酰胺基团。 这些化合物在抗癌活性和毒性方面优于丝裂霉素 C。 具体而言,所公开的化合物对肉瘤 180A 的有效用药区域更广,对 P$88 的延寿效果更强,骨髓抑制作用更小。 其中一些化合物具有高水溶性,有利于形成药物制剂,从而有助于制备优良的抗癌剂。
