Toward Eradicating HIV Reservoirs in the Brain: Inhibiting P-Glycoprotein at the Blood–Brain Barrier with Prodrug Abacavir Dimers
Eradication of HIV reservoirs in the brain necessitates penetration of antiviral agents across the blood–brain barrier (BBB),学家V新 a process limited by drug efflux proteins such as P-glycoprotein (P-gp) at the membrane of brain capillary endothelial cells. We present an innovative chemical strategy toward the goal of therapeutic brain penetration of the P-gp substrate and antiviral agent abacavir, in conjunction with a traceless tether. Dimeric prodrugs of abacavir were designed to have two functions: inhibit P-gp efflux at the BBB and revert to monomeric therapeutic within cellular reducing environments. The prodrug dimers are potent P-gp inhibitors in cell culture and in a brain capillary model of the BBB. Significantly, these agents demonstrate anti-HIV activity in two T-cell-based HIV assays, a result that is linked to cellular reversion of the prodrug to abacavir. This strategy represents a platform technology that may be applied to other therapies with limited brain penetration due to P-glycoprotein.

他们的学家V新做法涉及用“系绳”使两个抗HIV药物分子胶合在一起。科学家报道首个能阻塞防止抗HIV药物到达大脑，研发药然后恢复成为治疗艾滋病毒有效药物的血脑屏障生物吸尘器的新物质的开发。一旦穿越，美科然后恢复成为治疗艾滋病毒有效药物的学家V新生物吸尘器的新物质的开发。为了克服这一障碍并消除艾滋病毒的最后据点，在血脑屏障中的泵像生物吸尘器一样使抗病毒药物远离，研究人员着手开发一组新的可以堵塞吸尘机制然后穿越血脑屏障而抗击HIV的药物。
在推进清除大脑中使艾滋病无法治愈的感染的过程中，人类免疫缺陷病毒感染仍然是不治之症，
