What is Hydroxychloroquine (HCQ)?
Hydroxychloroquine (HCQ) accumulates in lysosomes, raising intra-lysosomal pH and inhibiting lysosomal enzyme activity. Acts as an autophagy flux inhibitor, TLR7/9 antagonist, and immune modulator. Bulk powder for large-scale autophagy inhibition research, innate immune studies, and lysosomal biology. Research use only.
