B4874-1ml | Hydroxychloroquine Sulfate [747-36-4] Clinisciences

Hydroxychloroquine Sulfate is a synthetic quinine derivative commonly used as an antimalarial drug [1]. It is also useful in managing systemic lupus erythematosus, rheumatoid arthritis, and other diseases. Also acts as an inhibitor of autophagy and toll-like receptor 7/9(TLR7/9) [1-3].

Five micromolar Hydroxychloroquine sulfate or chloroquine also has no measurable effect on intracellular pH, although these concentrations can inhibit TLR9 or 7 signaling induced by DNA or RNA ligands [4].

Hydroxychloroquine sulfate is prescribed for the treatment of lupus, and both Hydroxychloroquine sulfate and its analog chloroquine inhibit TLR7 and 9 signaling [4].

Cell experiment:[1]
Cell lines	Human renal cell cancer (RCC) cell lines, ACHN, Caki-1 and 769-P
Reaction Conditions	0 ~ 125 μM hydroxychloroquine for 48 h incubation
Applications	Hydroxychloroquine treatment inhibited growth of all three lines in a dose dependent manner. At the highest concentration of hydroxychloroquine, cell growth inhibition was similar between all three lines, ranging between 43 and 56%.
Animal experiment:[2]
Animal models	MRL/lpr mice
Dosage form	60 mg/kg Administered orally five times a week
Applications	Hydroxychloroquine was used as a control, exhibiting no impact on anti-dsDNA antibodies, whereas cytoxan caused a statistically significant suppression in anti-nuclear antibody titers. Hydroxychloroquine, as an inhibitor of toll-like receptor 7/9 (TLR7/9), could be a useful tool to study the mechanism and efficacy of other TLR7/9 inhibitors in vivo.
