Anti-virusagent 1 (compound 4i), a phosphoramidate prodrug of GS-5734, exhibits potent antiviral efficacy. It is primarily utilized in the study of coronavirus and Ebola virus (EBOV).
NHC-diphosphate is an active phosphorylated intracellular metabolite of β-d-N4-Hydroxycytidine (NHC) as a diphosphate form[1]. NHC is a pyrimidine ribonucleoside and behaves as a potent anti-virusagent. NHC effectively inhibits the replication of venezuelan equine encephalitis virus (VEEV), Chikungunya virus (CHIKV) and hepatitis C virus (HCV)[1]. Huh-7 cells are incubated with (10-50 μM; 4 h) NHC or a McGuigan phosphoramidate prodrug of NHC.Intracellular levels of the parental compounds and phosphorylated metabolites are measured using LC-MS MS. Small amounts of NHC-monophosphate (MP) and NHC-diphosphate can be observed, while NHC-triphosphate remains the most abundant metabolite.[1].
L-I-OddU, a potent and selective anti-Epstein-Barr virus (EBV) agent, is a L-5'-halo-dioxolane nucleoside analogue. It demonstrates antiviral activity by effectively suppressing replicative EBV DNA and viral protein synthesis [1] [2]. With an EC 50 value of 0.03 μM, L-I-OddU exhibits high potency against EBV while maintaining low cytotoxicity, as indicated by its CC 50 value of 1000 nM.
AMD-3451 free base is a dual CCR5 CXCR4 antagonist which may be useful in the treatment of a wide variety of R5, R5 X4, and X4 strains of human immunodeficiency virus type 1 (HIV-1) and HIV-2. AMD3451 is the first low-molecular-weight anti-HIV agent with selective HIV coreceptor, CCR5 and CXCR4, interaction.
