脂质体递送系统的大规模使用受到难以获得有效脂质体悬浮液的阻碍。已经提出了被动和主动加载策略来配制药物包封的脂质体,但受到低效率(被动)或高药物特异性(主动)的限制。在这里,我们提出了一种合成治疗性脂质体的有效且通用的装载策略。将热平衡技术与我们独特的脂质体合成方法相结合,可以以有效和可扩展的方式设计共负载的靶向脂质体,其效力比典型的被动封装技术高200倍。我们通过同时共加载亲水性和疏水性小分子以及通过靶向递送脂质体阿霉素至转移性乳腺癌细胞系MDA-MB-231来证明这种能力。分子动力学模拟被用来解释阿霉素和脂质体膜之间的相互作用在热平衡过程中。通过应对现有的挑战,我们开发了一种无与伦比的方法,将有助于制定新的治疗诊断和药物策略。
The wide-scale use of liposomal delivery systems is hampered by difficulties in obtaining potent liposomal suspensions. Passive and active loading strategies have been proposed to formulate drug encapsulated liposomes, but are limited by low efficiencies (passive) or high drug specificities (active). Here, we present an efficient and universal loading strategy for synthesizing therapeutic liposomes. Integrating a thermal equilibration technique with our unique liposome synthesis approach, co-loaded targeting liposomes can be engineered in an efficient and scalable manner with potencies 200-fold higher than typical passive encapsulation techniques. We demonstrate this capability through simultaneous co-loading of hydrophilic and hydrophobic small molecules and through targeted delivery of liposomal Doxorubicin to a metastatic breast cancer cell line MDA-MB-231. Molecular dynamic simulations are used to explain interactions between Doxorubicin and liposome membrane during thermal equilibration. By addressing the existing challenges, we have developed an unparalleled approach that will facilitate the formulation of novel theranostic and pharmaceutical strategies.
