摘要
为了达到更好的肿瘤治疗效果,研究者们针对肿瘤微环境设计出了双重和多重响应性智能纳米药物载体。其中基于酸敏感的双重响应性智能纳米药物载体的研究是最广泛、最常见的一种。在当前的研究中,该智能纳米药物载体已经初步实现了体内长循环、有效地抵达肿瘤细胞、在特定肿瘤微环境下控制药物释放等功效,增加了药物抗肿瘤疗效,有效地减少了药物对机体中正常组织的伤害。但是这类研究仍存在许多问题需要解决,如价格昂贵、载体结构复杂、体内药物传递机理不明确等,使其很难用于临床治疗。这里主要从酸-温度、酸-磁、酸-氧化还原、酸-酶、酸-光和酸-超声几个方面简单介绍了近几年的纳米载体研究进展,为进一步实现纳米药物临床应用奠定基础。
In order to achieve better tumor treatment, researchers have designed dual and multiple responsive smart nanocarriers in the tumor microenvironment. Among them, the research based on acid-sensitive dual-responsive nanocarriers is the most extensive and common one. Intelligent nanocarriers have initially achieved long circulation in body, effective accumulation in tumor cells, and controlled drug release in tumor microenvironment, with increased anti-tumor effect of drug and reduced damage to normal tissues. However, there are still many problems to be solved in current research, such as high price, complicated nanocarriers structure, and unclear mechanisms of drug delivery in the body, all hampering nanocarriers from clinical applications. This article introduces the progress of nanocarriers in recent years from the dual responsive aspects including acid-temperature, acid-magnetism, acid-redox, acid-enzyme, acid-light and acid-ultrasound, to provide reference for further clinical application of nanomedicine.
