TITLE: | Research progress of new drug delivery system of gambogic acid |
摘要: | 藤黄酸是藤黄科植物藤黄树GarciniahanburyiHook.f.的主要活性成分,可抑制多种肿瘤细胞的生长,但其溶解度低、半衰期短、稳定性差,在一定程度上限制了其在临床中的应用。为了改善上述缺点,提高藤黄酸的生物利用度,已有较多研究采用共价结合和物理包封法获得了具有靶向性、高渗透性、稳定性、生物兼容性、体内长循环等性质的新型藤黄酸给药系统,如聚合物前药递送系统、缺氧型前药递送系统、磁场响应型前药递送系统、多环境敏感型前药递送系统、仿生纳米药物递送系统等。本文对以上藤黄酸的新型给药系统及其特点进行综述,结果显示,药物载体的设计,较大程度地改善了藤黄酸的自身缺陷,藤黄酸药物载体中引入更多的响应基团可能会使其达到更好的抗肿瘤效果。 |
ABSTRACT: | Gambogic acid is the main active component of Garcinia hanburyi Hook. f. ,which can inhibit the growth of a variety of tumor cells. However ,its low solubility ,short half-life and poor stability limit its clinical application to a certain extent. In order to improve the above shortcomings and improve the bioavailability of gambogic acid ,many studies have used covalent binding and physical encapsulation methods to obtain a new gambogic acid delivery system with targeting ,high permeability ,stability, biocompatibility,in vivo long circulation and other properties ,such as polymer prodrug delivery system ,anoxic prodrug delivery system,magnetic field responsive prodrug delivery system ,multi environment sensitive prodrug delivery system ,bionic nano drug delivery system. This paper reviews the new drug delivery system and its characteristics of gambogic acid. The results show that the design of drug carrier has greatly improved the defects of gambogic acid ,and the introduction of more responsive groups into gambogic acid drug carrier may make it achieve better antitumor effect. |
