Virapinib
Virapinib is a macropinocytosis inhibitor with antiviral activity. Virapinib exhibits broad-spectrum antiviral activity against SARS-CoV-2, monkeypox virus, tick-borne encephalitis virus, and Ebola pseudotyped vesicular stomatitis virus, and it enhances Dengue Virus infection. Virapinib blocks viral entry by inhibiting macropinocytosis, reduces syncytium formation in SARS-CoV-2-infected cells, and impairs cellular entry of SARS-CoV-2 variants. Virapinib upregulates the expression of genes related to sterol biosynthesis. Virapinib can be used in studies related to COVID-19, monkeypox, tick-borne encephalitis, and Ebola virus infection.

Biological Activity
Virapinib (0.78-25 μM; 6 h pre-incubation; 72 h total incubation post-virus addition) inhibits SARS-CoV-2 S pseudotyped lentivirus infection in HEK293TACE2 cells in a dose-dependent manner, but has no effect on VSVg pseudotyped lentivirus infection[1].
Virapinib (0.5-10 μM; 6 h pre-incubation; 24 h total incubation post-virus wash-off) dose-dependently inhibits infection by the original SARS-CoV-2 in Vero E6 cells, with no cytotoxicity detected[1].
Virapinib (1-20 μM; 6 h pre-incubation; 24 h total incubation post-virus wash-off) dose-dependently inhibits infection by the original SARS-CoV-2, reduces syncytium formation in A549ACE2 cells, and shows no detectable cytotoxicity[1].
Virapinib (0.5-10 μM; overnight pre-incubation; 24 h total incubation post-virus infection) effectively reduces the infectivity of SARS-CoV-2 in 3D primary human hepatospheres[1].
Virapinib (5-25 μM; 16 h pre-incubation; 2 h dextran incubation) dose-dependently inhibits macropinocytosis in A549 cells and selectively blocks SARS-CoV-2 entry into A549ACE2 cells via the macropinocytosis pathway[1].
Virapinib (5-40 μM for tick-borne encephalitis virus and monkeypox virus; 10-25 μM for Ebola-pseudotyped vesicular stomatitis virus; 6 h pre-incubation) dose-dependently inhibits infections by tick-borne encephalitis virus, monkeypox virus, and Ebola-pseudotyped vesicular stomatitis virus in A549 cells. It shows no activity against Andes virus, only weak activity against adenovirus, and enhances dengue virus infection[1].

Result:Showed significant upregulation of genes related to sterol biosynthesis, including HMGCS1, HMGCR, and MVK, in MCF-7 cells via RNA sequencing.
Identified 'steroid biosynthesis' as the most significantly induced pathway via KEGG pathway enrichment analysis.
Increased HMGCR, HMGCS1, and MVK mRNA levels in A549ACE2 cells via qRT-PCR, without altering total cellular cholesterol levels or cholesterol distribution.
