Activation of HIV-1 replication causes oxidative stress, which in turn potentiates HIV-1 replication. The common basis for the compounds of the present invention is: A) the capacity of reactivating HIV-1 from latency, and B) the ability to counteract the cellular machinery which activates in order to limit the effects of oxidative stress. In this way, oxidative stress can be potentiated and a “chain reaction” is sparked. This “chain reaction” induces a more efficient reactivation of HIV-1 from latency and, in some cases, induces selective killing of the infected cells. Actions A) and B) can either be carried out by one drug exerting both effects, or obtained by the combined use of distinct drugs. There are two main cellular machineries counteracting oxidative stress, i.e. the thioredoxin (Trx) thioredoxin reductase (TrxR) system and glutathione. Herein, we present drug strategies capable of exerting action B) by blocking either of the two machineries.
HIV-1复制的激活会引起氧化应激,从而加强HIV-1的复制。本发明化合物的共同基础是:A)重新激活HIV-1潜伏感染的能力,和B)对抗细胞机制,以限制氧化应激的影响。通过这种方式,氧化应激可以被增强并引发“连锁反应”。这种“连锁反应”诱导更有效的HIV-1潜伏感染的重新激活,并在某些情况下诱导感染细胞的选择性杀死。行动A)和B)可以由一种药物实现两种效果,也可以通过联合使用不同药物获得。对抗氧化应激的两种主要细胞机制是硫氧还蛋白(Trx)硫氧还蛋白还原酶(TrxR)系统和谷胱甘肽。在此,我们提出了能够通过阻断这两种机制之一来实现B)行动的药物策略。
