Cepharanthine is a naturally occurring bisbenzylisoquinoline alkaloid isolated from Stephania cepharantha Hayata, a plant traditionally used in East Asian medicine. It has been extensively studied for its diverse pharmacological properties, including anti‑inflammatory, immunomodulatory, antiviral, and anticancer activities.
In recent years, Cepharanthine has gained global attention for its potential in antiviral research, particularly for its ability to inhibit viral entry and replication. It is widely used as a high‑purity reference standard in pharmaceutical, biochemical, and natural product studies.
