Background:

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].

Protocol:

Cell experiment [1]:
Cell lines	C8166 cells
Preparation Method	Cells were seeded each well in a 96-well plate with Azvudine hydrochloride . The plate was placed in a humidified incubator. After incubation of 3-7 days, the percentage inhibition of syncytia formation was scored or the level of p24 was measured by ELISA and 50% effective concentration (EC50) were calculated.
Reaction Conditions	2nM Azvudine hydrochloride for 3-7 days at 37°C
Applications	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.
Animal experiment [2]:
Animal models	Lethal EV71 and CA16 infection in neonatal mouse models
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.
