of micelles with nanofiber geometry as nanocarriers for hydrophobic drugs. Here we show that the conjugate of penetratin, a cell‐penetrating peptide (CPP) with blood‐brain barrier (BBB) permeability, and deferasirox (DFX), a hydrophobic iron chelator, self‐assembles to form micelles at a very low concentration (∼15 mg/L). The critical micelle concentration (CMC) was determined, and the micelles were
使用具有纳米纤维几何形状的胶束作为疏水性药物的纳米载体的兴趣与日俱增。此处我们显示了具有血脑屏障(BBB)渗透性的细胞穿透肽(CPP)渗透肽和疏水性铁螯合剂Deferasirox(DFX)的结合物自组装形成非常低浓度的胶束(约15 mg / L)。确定了临界胶束浓度(CMC),并将该胶束用于溶解姜黄素(一种疏水的抗神经变性药物),以成功地通过BBB模型RBE4细胞传递。姜黄素负载的胶束的透射电子显微镜图像证实了纳米纤维的形成。这些结果表明,CPP-药物偶联物可用作纳米载体的潜力。©2015 Wiley Periodicals,Inc.生物聚合物(Pept Sci)104:712–719,2015年。
