摘　　要：背景:抗肿瘤药物给药后,在机体内往往非特异性分布,毒副作用大,生物利用度低,具有主动靶向功能的药物载体可成功解决这一问题。目的:综合论述了近年来国内外制备主动靶向药物载体应用于抗肿瘤药物输送的最新研究,归纳总结出药物载体的各类主动靶向策略。方法:应用计算机检索平台ISI Web of Knowledge检索2004/2011各英文数据库,检索词采用与抗肿瘤药物载体靶向给药密切相关的关键词,如"tumor,drug carrier,active targeting"等,共检索到文献58篇,最终纳入符合标注的文献26篇。结果与结论:主动靶向策略是设计抗肿瘤药物载体时首先需要考虑也是最为重要的环节,它决定了药物载体实际的药物输送效果以及药物的生物利用度。具有主动靶向策略的药物载体可携带抗肿瘤药物到达肿瘤部位,显著减少机体内其他部位药物的非特异性分布,从而降低其毒副作用,提高生物利用度。BACKGROUND： The non-specific distribution of anticancer drugs in vivo may cause serious side effects and low bioavailability. Drug carriers with the active targeting abilities can solve these problems. OBJECTIVE： To review the recent studies on carrier preparation for anticancer drug delivery and summarize different types of active targeting strategies for drug carrier. METHODS： A computer＊based online search was performed for articles published from 2004 to 2011 in Web of Knowledge database with the English key words that closely related to various active targeting strategies, such as ＂tumor drug carrier, active targeting＂. Totally 58 articles were retrieved, and finally 26 of them met the requirement. RESULTS AND CONCLUSION： Active targeting strategy is the first problem need to consider and the most important part in designing anticancer drug carriers. It contributes to the actual effect of drug delivery and bioavailability of drug. Drug carriers with various active targeting abilities can carry antitumor drugs to tumor sites and significantly reduced the non-specific distribution of drugs in vivo in order to decrease the side effects and enhanced bioavailability.
