Preparation Method |
The neonatal mice were randomly divided into five groups, and each group contained three litters . One group was inoculated intracerebrally with DMEM (10 µl/mouse) and after 1 h injected intraperitoneally with DMSO. Two groups were inoculated intracerebrally with EV71 CC063 and after 1 h injected intraperitoneally with Azvudine hydrochloride or DMSO. Azvudine hydrochloride was injected intraperitoneally on days 1, 3, 6, 9, and 12 |
Dosage form |
1 mg/kg Azvudine hydrochloride on days 1, 3, 6, 9, and 12 |
Applications |
EV71 and CA16 challenge resulted in 90% and 30% mortality, respectively, while Azvudine hydrochloride Azvudine hydrochloride treatment greatly reduced mortality to 20% and 0%. Azvudine hydrochloride treatment significantly improved clinical presentation and survival, indicating that FNC effectively protects against EV71 and CA16 challenge in vivo. |

Azvudine hydrochloride is a potent nucleoside reverse transcriptase inhibitor (NRTI) that has antiviral activity against HIV, HBV, and HCV,(HIV-1 (EC50s 0.03 to 6.92 nM) and HIV-2 (EC50s 0.018 to 0.025 nM))[1]. Azivudine hydrochloride could inhibit SARS-CoV-2 and HCoV-OC43 coronavirus with EC50 1.2-4.3 μM[3].
In C8166 cells,Azvudine hydrochloride showed strong inhibition against wild-type HIV-1 IIIB and HIV-1 RF, with 50% effective concentration values (EC 50) ranging from 30 to 110 pM[2].
EV71 and CA16 challenge resulted in 90% and 30% mortality, respectively, while Azvudine hydrochloride treatment greatly reduced mortality to 20% and 0%. Azvudine hydrochloride treatment significantly improved clinical presentation and survival, indicating that Azvudine hydrochloride effectively protects against EV71 and CA16 challenge in vivo[4].
Treating SARS-CoV-2 infected rhesus macaques with Azvudine hydrochloride (0.07 mg/kg, qd, orally) reduced viral load, recuperated the thymus, improved lymphocyte profiles, alleviated inflammation and organ damage, and lessened ground-glass opacities in chest X-ray[3].
Azvudine hydrochloride clinical efficacy in curing COVID-19 was significant, showing inhibition of SARS-CoV-2 replication in all 31 patients after treatment with Azvudine hydrochloride, and the anti-coronavirus activity of Azvudine hydrochloride was also demonstrated in animal experiments using RM[5].

Azvudine is a thymus-homing anti-SARS-CoV-2 drug effective in treating COVID-19 patients
Signal Transduct Target Ther2021 Dec 6;6(1):414.PMID: 34873151DOI: 10.1038/s41392-021-00835-6
Azvudine (FNC) is a nucleoside analog that inhibits HIV-1 RNA-dependent RNA polymerase (RdRp). Recently, we discovered FNC an agent against SARS-CoV-2, and have taken it into Phase III trial for COVID-19 patients. FNC monophosphate analog inhibited SARS-CoV-2 and HCoV-OC43 coronavirus with an EC50 between 1.2 and 4.3 ¦̍, depending on viruses or cells, and selective index (SI) in 15-83 range. Oral administration of FNC in rats revealed a substantial thymus-homing feature, with FNC triphosphate (the active form) concentrated in the thymus and peripheral blood mononuclear cells (PBMC). Treating SARS-CoV-2 infected rhesus macaques with FNC (0.07 mg/kg, qd, orally) reduced viral load, recuperated the thymus, improved lymphocyte profiles, alleviated inflammation and organ damage, and lessened ground-glass opacities in chest X-ray. Single-cell sequencing suggested the promotion of thymus function by FNC. A randomized, single-arm clinical trial of FNC on compassionate use (n = 31) showed that oral FNC (5 mg, qd) cured all COVID-19 patients, with 100% viral ribonucleic acid negative conversion in 3.29 ¡À 2.22 days (range: 1-9 days) and 100% hospital discharge rate in 9.00 ¡À 4.93 days (range: 2-25 days). The side-effect of FNC is minor and transient dizziness and nausea in 16.12% (5/31) patients. Thus, FNC might cure COVID-19 through its anti-SARS-CoV-2 activity concentrated in the thymus, followed by promoted immunity.

A Randomized, Open-Label, Controlled Clinical Trial of Azvudine Tablets in the Treatment of Mild and Common COVID-19, a Pilot Study
Adv Sci (Weinh)2020 Aug 13;7(19):2001435.PMID: 32837847DOI: 10.1002/advs.202001435
Coronavirus disease 2019 (COVID-19) has spread worldwide. To date, no specific drug for COVID-19 has been developed. Thus, this randomized, open-label, controlled clinical trial (ChiCTR2000029853) was performed in China. A total of 20 mild and common COVID-19 patients were enrolled and randomly assigned to receive Azvudine and symptomatic treatment (FNC group), or standard antiviral and symptomatic treatment (control group). The mean times of the first nucleic acid negative conversion (NANC) of ten patients in the FNC group and ten patients in the control group are 2.60 (SD 0.97; range 1-4) d and 5.60 (SD 3.06; range 2-13) d, respectively (p = 0.008). The mean times of the first NANC of four newly diagnosed subjects in the FNC group and ten subjects in the control group are 2.50 (SD 1.00; range 2-4) d and 9.80 (SD 4.73; range 3-19) d, respectively (starting from the initial treatment) (p = 0.01). No adverse events occur in the FNC group, while three adverse events occur in the control group (p = 0.06). The preliminary results show that FNC treatment in the mild and common COVID-19 may shorten the NANC time versus standard antiviral treatment. Therefore, clinical trials of FNC treating COVID-19 with larger sample size are warranted.

Azvudine, a novel nucleoside reverse transcriptase inhibitor showed good drug combination features and better inhibition on drug-resistant strains than lamivudine in vitro
PLoS One2014 Aug 21;9(8):e105617.PMID: 25144636DOI: 10.1371/journal.pone.0105617
Azvudine is a novel nucleoside reverse transcriptase inhibitor with antiviral activity on human immunodeficiency virus, hepatitis B virus and hepatitis C virus. Here we reported the in vitro activity of Azvudine against HIV-1 and HIV-2 when used alone or in combination with other antiretroviral drugs and its drug resistance features. Azvudine exerted highly potent inhibition on HIV-1 (EC(50)s ranging from 0.03 to 6.92 nM) and HIV-2 (EC(50)s ranging from 0.018 to 0.025 nM). It also showed synergism in combination with six approved anti-HIV drugs on both C8166 and PBMC. In combination assay, the concentrations of Azvudine used were 1000 or 500 fold lower than other drugs. Azvudine also showed potent inhibition on NRTI-resistant strains (L74V and T69N). Although M184V caused 250 fold reduction in susceptibility, Azvudine remained active at nanomolar range. In in vitro induced resistant assay, the frequency of M184I mutation increased with induction time which suggests M184I as the key mutation in Azvudine treatment. As control, lamivudine treatment resulted in a higher frequency of M184I/V given the same induction time and higher occurrence of M184V was found. Molecular modeling analysis suggests that steric hindrance is more pronounced in mutant M184I than M184V due to the azido group of Azvudine. The present data demonstrates the potential of Azvudine as a complementary drug to current anti-HIV drugs. M184I should be the key mutation, however, Azvudine still remains active on HIV-1LAI-M184V at nanomolar range.
