双语推荐:铂类药物

经过将近半个世纪的发展,铂类药物的研究取得了重要进展。一方面,新型铂类药物不断涌现,奈达、奥沙利、乐、舒相继通过临床试验投入,临床使用,另还有许多卡和顺似物、亲脂性的配合物、具有空间位阻的配合物和可口服的配合物正处于临床试验阶段,其中有些可能成为未来的新型铂类药物;另一方面,铂类药物联合其他抗癌药物治疗能显著提高抗癌疗效,对肿瘤耐药性研究也取得了重要突破。
The important progress in platinum drugs has been witnessed in past nearly half a century. On the one hand, new platinum drugs such as nedaplatin, oxaliplatin, lobaplatin and sunpla have continuously emerged, and put into use in clinic after clinical trials were successfully completed. The analogues of cisplatin and carboplatin, the lipophilic and sterically hindered complexes and even some oral platinum complexes are in clinical trials, some of which will become new-type platinum drugs in the near future. On the other hand, combination of platinum with other anticancer drugs has signiifcantly improved the anticancer efifcacy and some important breakthroughs have been made in platinum-induced chemoresistance research.
