Novel platinum complexes represented by the formula: ##STR1## wherein A is alkylene having carbon atoms of from 1 to 3; R.sub.1, R.sub.2, R.sub.3 and R.sub.4 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 ##STR2## 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.
公开了一种由以下式子表示的新型铂配合物:##STR1##
其中,A为碳原子数为1至3的烷基;R1、R2、R3和R4相同或不同,分别为氢或碳原子数为1至4的烷基;X和Y独立地表示卤素原子,或结合在一起形成##STR2##,l、m和n独立地表示0或1。同时,公开了一种制备这种铂配合物的方法。这些铂配合物具有高抗肿瘤活性和低毒性,并且易溶于水。因此,它们非常有用作为抗肿瘤剂。
