Antiviral agents

Definition

Antiviral agents are medications specifically designed to treat viral infections by inhibiting the development and replication of viruses. These agents can target various stages of a virus's life cycle, including entry into cells, replication, and assembly of new viral particles. Their role is crucial in managing viral diseases, making them significant in both medical and economic contexts, particularly with respect to marine algae-derived compounds that may exhibit antiviral properties.
