摘要
响应性药物递送系统的紧急情况有助于降低细胞毒性、改善组织渗透性和延长活性药物的循环时间。特别是酶响应纳米平台由于酶催化反应的特异性和效率而引起了很多关注。在这篇综述中,总结了过去 5 年设计的基于酶的单反应给药系统。这些药物递送系统由不同的肿瘤相关酶引入,例如基质金属蛋白酶、酯酶、透明质酸酶、半胱天冬酶和组织蛋白酶。此外,还描述了由双重刺激激活的酶敏感纳米平台。虽然过去几年取得了很大进展,但转化为临床实践仍然很困难。因此,还讨论了三个障碍(酶异质性、反应环境、动物模型)。简而言之,酶激活药物递送系统在治疗癌症方面具有巨大潜力。
关键词: 酶响应、基质金属蛋白酶、酯酶、透明质酸酶、半胱天冬酶、组织蛋白酶。
