Virus is a small infectious agent that replicates only inside the living cells of other organisms through various pathways, and causes the damage to the host cells. Common diseases caused by virus include smallpox, the common cold, chickenpox, influenza, shingles, hanta fever, herpes, etc. AIDS, polio, and Ebola are examples of life threatening serious viral diseases caused by HIV, poliovirus, and Ebola virus, respectively.

The Anti-Viral Compound Library from TargetMol contains 800 compounds with anti-virus bioactivity, and is an appropriate tool for drug repurposing for new anti-virus drug discovery based on the fact that these viruses rely on common host cellular mechanisms to promote discrete stages of their life cycles.
