Antiviral Compound Library

1,180 compounds

Viruses are much simpler organisms than bacteria, and they are made from protein substances and nucleic acid. Despite the fact that the exact mechanism of infection is extremely specific to each type of virus, the general scheme of infection can be represented in the following manner: A virus is absorbed at the surface of a host cell and then permeates through the membrane, where it releases nucleic acid from its protein protection. Then the viral nucleic acid begins to replicate, and transcription of the viral genome takes place either in the cytoplasm, or in the nucleus of the host cell. As a result of these events, a large amount of viral nucleic acid and protein are made to make new generations of virions. Therefore, one mechanism of action of antiviral drugs is to interfere with the ability of a virus to get into a target cell. A second mechanism of action is to target the processes that synthesize virus components after a virus invades a cell, such as nucleotide or nucleoside analogs.

MCE designs a unique collection of 1,180 anti-virus compounds that target several viruses, including SARS-CoV, HBV, HCV, HIV, HSV and Influenza Virus. It’s an effective tool for anti-virus drug discovery.
