Current antiretroviral HIV therapies continue to have problems related to procedural complications, toxicity, and uncontrolled side effects. In this study, amino phenylboronic acid-modified carbon dots (APBA-CDs) were introduced as a new nanoparticle-based on gp120 targeting that inhibits HIV-1 entry processes. Prolonged by simple pyrolysis for preparing carbon dots, this report further explores attributing amino phenylboronic acid on carbon dots, which prove the formation of graphene-like structures on carbon dots and boronic acid sites, thereby enabling the enhancement of positive optical properties through photoluminescent detection. Aside from performing well in terms of biocompatibility and low cytotoxicity (the CC reach up to 11.2 mg/mL), APBA-CDs exhibited superior capabilities in terms of prohibiting HIV-1 entry onto targeted MOLT-4 cells recognized by the delimitations of syncitia formation and higher ATP signal rather than bare carbon dots. The modified carbon dots also promote dual-action on HIV-1 treatment by both intracellularly and extracellularly viral blocking by combining with the Duviral drug, along with compressing p24 antigen signals that are better than APBA-CDs and Duviral itself.
目前的抗逆转录病毒HIV疗法在程序并发症、毒性和无法控制的副作用方面仍然存在问题。在本研究中,引入了氨基苯硼酸修饰的碳点(APBA-CDs),这是一种基于靶向gp120的新型纳米颗粒,可抑制HIV-1进入过程。通过简单热解制备碳点的方法得到了延长,本报告进一步探索了在碳点上引入氨基苯硼酸,这证明了碳点上形成了类石墨烯结构和硼酸位点,从而通过光致发光检测增强了正光学性质。除了在生物相容性和低细胞毒性方面表现良好(CC高达11.2 mg/mL)外,APBA-CDs在阻止HIV-1进入通过多核巨细胞形成界限和更高ATP信号识别的靶向MOLT-4细胞方面表现出优于裸碳点的能力。通过与杜韦拉药物联合,修饰后的碳点还通过细胞内和细胞外病毒阻断对HIV-1治疗发挥双重作用,同时压缩p24抗原信号,其效果优于APBA-CDs和杜韦拉本身。
