Hydroxychloroquine is a synthetic quinine derivative commonly used as an antimalarial drug. Hydroxychloroquine is also used to treat symptoms of rheumatoid arthritis and discoid or systemic lupus erythematosus. It inhibits autophagy and induces autophagic cell death (IC₅₀ = 30 µM), suggesting potential applications in research and medicine.
