Novel platinum complexes represented by the formula:
wherein A is alkylene having carbon atoms of from 1 to 3; R,, R2, R3 and R4 are the same or different and are hydrogen or alkyl having carbon atoms of from 1 to 4; X and Y are independently a halogen atom, or combined together to form
or
and ℓ, m and n are independently 0 or 1, and a process for preparing the same are disclosed. These platinum complexes have high antitumor activity and low toxicity, and are easily soluble in water. Therefore, they are very useful as an antitumor agent.
由式表示的新型
铂络合物:
其中 A 是碳原子数为 1 至 3 的亚烷基;R、R2、R3 和 R4 相同或不同,是氢或碳原子数为 1 至 4 的烷基;X 和 Y 独立地是卤素原子,或结合在一起形成
或
和 ℓ、m 和 n 独立地为 0 或 1,并公开了制备这些
铂络合物的工艺。这些
铂络合物具有高抗肿瘤活性和低毒性,并且易溶于
水。因此,它们作为抗肿瘤剂非常有用。
