A cis-diammineplatinum(II)-polyglutamic acid complex proved to have marked trypanocidal activity in vivo. When 5 mg of platinum per kg was administered daily for 5 days or when 20 mg of platinum per kg was administered on days 1, 3, and 6, five of five treated Trypanosoma congolense-infected mice were cured. In contrast, cis-platin was ineffective at all doses tested. We believe that the complex has a much higher therapeutic ratio than does uncomplexed drug because it is less toxic.
顺二氨合铂(II)-聚谷氨酸复合物在体内显示出显著的杀锥虫活性。当以每千克5毫克铂的剂量每日给药5天,或在第1、3和6天以每千克20毫克铂的剂量给药时,五只感染刚果锥虫的小鼠经治疗后全部治愈。相比之下,顺铂在所有测试剂量下均无效。我们认为该复合物的治疗指数比未复合的药物高得多,因为它的毒性较小。
