Novel in vivo model for the study of human immunodeficiency virus type 1 transcription inhibitors: evaluation of new 6-desfluoroquinolone derivatives. | LitMetric

AI Article Synopsis

Article Abstract

Two novel 6-desfluoroquinolone derivatives, HM-12 and HM-13, were evaluated for anti-human immunodeficiency virus (anti-HIV) activity in acutely, chronically, and latently HIV type 1 (HIV-1)-infected cell cultures and were found to behave as potent HIV-1 transcription inhibitors. In order to extend this result in vivo, we developed an artificial hu-SCID mouse model for HIV-1 latency based on SCID mice engrafted with latently HIV-1-infected promyelocytic OM-10.1 cells in which HIV-1 can be reactivated in vivo by the administration of human tumor necrosis factor alpha (hTNF-alpha). Treating these SCID mice with HM-12 or HM-13 prior to hTNF-alpha stimulation resulted in a pronounced suppressive effect on viral reactivation. Since both quinolone derivatives were able to inhibit the reactivation of HIV-1 from this artificial viral reservoir in vivo, we provide encouraging evidence for the use of quinolones in the control of HIV-1 infections.
