Vorinostat (SAHA) is a potent and orally active pan-inhibitor of HDAC1, HDAC2 and HDAC3 (Class I), HDAC6 and HDAC7 (Class II) and HDAC11 (Class IV), with ID₅₀ values of 10 nM and 20 nM for HDAC1 and HDAC3, respectively. Vorinostat induces cell apoptosis. Vorinostat is also an effective inhibitor of human papillomaviruse (HPV)-18 DNA amplification.

2'-Deoxy-5'-O-DMT-2'-fluorouridine, a nucleoside analogue, is a 5’-O-DMTr-5-FUDR derivative with potent anti-yellow fever (YFV) activity.

Ansuvimab (Ansuvimab-zyk) is a recombinant human monoclonal IgG1 antibody that exhibits antiviral activity against Zaire ebolavirus. Ansuvimab binds to the glycoprotein on Zaire ebolavirus to block its entry into host cells.

Maftivimab (REGN3470-3471-3479) is a human monoclonal antibody targeting the glycoprotein of Zaire ebolavirus (ZEBOV), with an IC₅₀ of 0.17 nM and a K_d of 2.97 nM. Maftivimab is applicable to research related to Zaire ebolavirus infection and Ebola virus disease.

DSHS00884 is a potent human papillomavirus E6 inhibitor with an IC₅₀ of 10 μM.

Galidesivir (BCX4430) hydrochloride, an adenosine analog and a direct-acting antiviral agent, disrupts viral RNA-dependent RNA polymerase (RdRp) activity. Galidesivir hydrochloride is active in vitro against many RNA viral pathogens, including the filoviruses and emerging infectious agents such as MERS-CoV, SARS-CoV, and SARS-CoV-2. Galidesivir hydrochloride inhibits some negative-sense RNA viruses with EC₅₀s ranging from ~3 to ~68 μM.

RMC-113 is a PIP4K2C and PIKfyve inhibitor with the K_i vaules of 46 nM and 370 nM. RMC-113 reverses SARS-CoV-2-induced impairment of autophagic flux. RMC-113 shows antiviral activity.

Atoltivimab (REGN3470), or maftivimab/odesivimab (Inmazeb) is the first Food and agent Administration (FDA)-approved monoclonal antibody to target Zaire ebolavirus (EBOVs) infection.

Odesivimab is a human monoclonal antibody, targeting Ebola virus glycoprotein with a K_D value of 7.74 nM for recombinant histidine-tagged Makona strain Ebola virus glycoprotein ectodomain protein. Odesivimab can be used in research of Ebola virus infection.
