A novel platinum (II) complex represented by the following formula (A): ##STR1## wherein R.sub.1 represents C.sub.1 -C.sub.5 lower hydrocarbon group, R.sub.2 and R.sub.3 represents hydrogen atom or C.sub.1 -C.sub.3 lower hydrocarbon group, the configuration of 1,2-diaminocyclohexane being cis, trans-l- or trans-d-. Since the platinum (II) complex has a strong anti-tumor activity and its toxicity is low, it is useful as an agent for treating malignant tumor.
一种新型
铂(II)配合物,其
化学式如下(A): ##STR1## 其中,R.sub.1代表C.sub.1-C.sub.5下游碳氢基团,R.sub.2和R.sub.3代表氢原子或C.sub.1-C.sub.3下游碳氢基团,
1,2-二氨基环己烷的构型为顺式、反式-l或反式-d-。由于该
铂(II)配合物具有强烈的抗肿瘤活性且毒性低,因此可用作治疗恶性肿瘤的药物。
