The exploitation of exosomes as drug delivery vehicles offers important advantages compared to other nanoparticulate drug delivery systems such as liposomes and polymeric nanoparticles; exosomes are non-immunogenic in nature due to similar composition as body's own cells. In this article, the origin and structure of exosomes as well as their biological functions are outlined. We will then focus on specific applications of exosomes as drug delivery systems in pharmaceutical drug development. An overview of the advantages and challenges faced when using exosomes as a pharmaceutical drug delivery vehicles will also be discussed.展开更多
甘草Glycyrrhizae Radix et Rhizoma是中医临床常用中药之一,具有补脾益气、清热解毒、祛痰止咳、缓急止痛、调和诸药等功能。其主要活性成分为皂苷、黄酮、多糖等。其中,皂苷类成分甘草酸、甘草次酸不仅对肝癌、肺癌、乳腺癌等多种癌...甘草Glycyrrhizae Radix et Rhizoma是中医临床常用中药之一,具有补脾益气、清热解毒、祛痰止咳、缓急止痛、调和诸药等功能。其主要活性成分为皂苷、黄酮、多糖等。其中,皂苷类成分甘草酸、甘草次酸不仅对肝癌、肺癌、乳腺癌等多种癌症具有抑制作用,还能与化疗药物联用增加药效,同时可被开发用作药物递送的载体材料以解决药物低水溶性、低生物利用度、高毒副作用等问题。研究发现,甘草酸、甘草次酸的增溶作用可能与其两亲性结构有关,有望进一步探索它们作为药物跨膜运输载体的特性。基于甘草的抗肿瘤机制,系统地对甘草酸、甘草次酸在药物递送系统方面的应用进行综述,为开发甘草酸、甘草次酸作为药物递送系统辅料的深入研究提供参考。展开更多
