抗逆转录病毒药物依非韦伦(efavirenz)显示出许多理想的药代动力学特性,例如半衰期长,可以每天服用一次,但存在中枢神经系统安全性问题。已经探索了各种纳米技术来减轻依非韦伦的一些限制。虽然在提高生物利用度方面取得了进展,但没有人试图评估增加暴露于依非韦伦对中枢神经系统安全性的影响。研究了依非韦伦在人脑微血管内皮细胞/D3脑内皮细胞系中水和固体药物纳米颗粒(SDN)的摄取情况。利用一组转运和内吞抑制剂探索了摄取机制。金刚烷胺显著降低了依非韦伦水溶液的细胞积聚,但在sdn中没有观察到这种情况。依非韦伦sdn的吸收随时间的变化而降低,但依非韦伦水溶液的浓度不受影响。这些数据表明,依非韦伦是脑内皮细胞中转运蛋白的底物(金刚烷胺是有机阳离子转运蛋白1和2的抑制剂),sdn的形成可能绕过这种相互作用,有利于动力蛋白介导的内吞作用机制。
The antiretroviral drug efavirenz displays many desirable pharmacokinetic properties such as a long half‐life enabling once daily dosing but suffers from central nervous system safety issues. Various nanotechnologies have been explored to mitigate some of the limitations with efavirenz. While there has been progress in increasing the bioavailability, there has been no attempt to assess the impact of increased exposure to efavirenz on central nervous system safety. The uptake of aqueous and solid drug nanoparticle (SDN) formulations of efavirenz was assessed in the human cerebral microvessel endothelial cells/D3 brain endothelial cell line. The mechanisms of uptake were probed using a panel of transport and endocytosis inhibitors. The cellular accumulation of an efavirenz aqueous solution was significantly reduced by amantadine, but this was not observed with SDNs. The uptake of efavirenz SDNs was reduced by dynasore, but concentrations of the efavirenz aqueous solution were not affected. These data indicate that efavirenz is a substrate for transporters in brain endothelial cells (amantadine is an inhibitor of organic cation transporters 1 and 2), and formation of SDNs may bypass this interaction in favour of a mechanism involving dynamin‐mediated endocytosis.
