Description:

WARNING: This product is for research use only, not for human or veterinary use.

Hydroxychloroquine is an autophagy inhibitor. It acts by inducing apoptosis of renal cancer cells in vitro and inhibiting TLR9. Hydroxychloroquine (HCQ) is a medication used to prevent and treat malaria in areas where malaria remains sensitive to chloroquine. Other uses include treatment of rheumatoid arthritis, lupus, and porphyria cutanea tarda. It is taken by mouth. It is also being studied as an experimental treatment for coronavirus disease 2019 (COVID-19).
