What are Hydroxyquinoline Derivatives in ATC Class P01AA?
ATC Classification Overview:
The Anatomical Therapeutic Chemical (ATC) classification system assigns P01AA to chemotherapeutic agents—more specifically, antiparasitic and antiprotozoal agents based on their pharmacological activity.
Hydroxyquinoline Derivatives:
These compounds are derivatives of quinoline with hydroxyl groups, known for broad-spectrum antiparasitic and antimicrobial activity. Key examples include Chloroquine, Hydroxychloroquine, and less common derivatives synthesized for enhanced pharmacodynamic properties.
