We developed a nanoparticle based on a cell-penetrating peptide-PROTAC conjugate with a disulfide linker, , and dextran sulfate, enhancing cellular uptake and BRD4 degradation. This delivery platform significantly improves PROTAC bioavailability and offers a promising strategy to overcome membrane permeability challenges for targeted protein degradation.
我们开发了一种基于细胞穿透肽-蛋白酶体靶向嵌合体(PROTAC)共轭物、二硫键连接子以及硫酸葡聚糖的纳米颗粒,可增强细胞摄取和BRD4降解。该递送平台显著提高了PROTAC的生物利用度,并为克服靶向蛋白质降解的膜通透性挑战提供了一种有前景的策略。
