抗病毒用藥

In the absence of a good knowledge of how the target virus worked, and viruses use the host's cells to replicate. Antivirals development is a very time-consuming, hit-or-miss procedure. It was not efficient in discovering effective antivirals which had few side effects.  
A virus is a small infectious agent replicates inside the host’s cells, it can infect all types of life forms. Virus can cause human disease Such as HBV, HCV, Herpes, HIV, Influenza and COVID-19.
 Many serious diseases such as Ebola virus disease, AIDS (HIV), influenza, SARS and coronavirus disease (COVID-19) are caused by viruses. 

Hepatitis B is the world's most common liver infection. It is caused by the hepatitis B virus (HBV), which attacks and injures the liver. It can cause both acute and chronic infection.

Herpes simplex is a viral infection caused by the herpes simplex virus. This virus affects the external genitalia, anal region, mucosal surfaces, and skin in other parts of the body.

Arjil drugs decrease the viral propagation in oral epithelial cells after HSV 1 infection.

HIV人類免疫缺乏病毒

The human immunodeficiency viruses (HIV) are two species of Lentivirus that infect humans. Over time, they cause acquired immunodeficiency syndrome (AIDS), a condition in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive.

Protease inhibitors (PIs) are a class of antiviral drugs that are widely used to treat HIV/AIDS and hepatitis C. Protease inhibitors prevent viral replication by selectively binding to viral proteases (e.g. HIV-1 protease) and blocking proteolytic cleavage of protein precursors that are necessary for the production of infectious viral particles.
