摘要
紫杉醇是目前最有效的抗癌药物之一,但由于它的水溶性、药代动力学和体内分布性能较差,且其增溶剂对人体有很强的毒副作用,限制了它的临床应用.为了提高紫杉醇的水溶性、渗透率及稳定性,研究人员制备出一种具有缓释作用、可控及肿瘤靶向的药物——透明质酸-紫杉醇纳米制剂.以透明质酸为载体的纳米载药系统可以降低紫杉醇的毒副作用,利用合适的给药途径将透明质酸-紫杉醇纳米制剂输送至体内,提高了药物的靶向性、水溶性及长循环能力,使药物通过扩散、包吞或受体介导的内吞作用进入细胞.文章综述了透明质酸-紫杉醇纳米制剂在多种恶性肿瘤中的应用.
Paclitaxel is one of the most effective broad-spectrum chemotherapeutic agents in the treatment of cancers.However,its clinical application has been limited due to its poor water solubility.Its current clinical administration results in serious side effects and has undesired pharmacokinetics and biodistribution.Therefore,it is need to develope alternate drug delivery systems of paclitaxel to enhance its solubility,permeability and stability,furthermore to promote a sustained,controlled and targeted delivery.Hyaluronic acid as the carrier of drug delivery system can solve the problems.Hyaluronic acid-paclitaxel nanoparticles have high anticancer efficiency in drug encapsulation and tumor cellular uptake,due to their appropriate size,surface modification and interaction with CD44.This review focuses on recent applications of hyaluronic acid-paclitaxel nanoparticles in a variety of malignant tumors.
