Background:

Hydroxychloroquine-d₄(sulfate) is intended for use as an internal standard for the quantification of hydroxychloroquine by GC- or LC-MS. Hydroxychloroquine is an aminoquinoline with antimalarial, anti-inflammatory, and antiviral activities.^1,2,3,4It is active against the chloroquine-sensitive NF54 and D6 strains ofP. falciparum(IC₅₀s = 16.3 and 15 nM, respectively) but has decreased activity against chloroquine-resistantP. falciparumstrains (IC₅₀s = 422.7-1,735.3 nM).¹Hydroxychloroquine inhibits production of IL-22, IL-17A, and IL-6 induced by phorbol 12-myristate 13-acetate and ionomycin in peripheral blood mononuclear cells (PBMCs) isolated from healthy individuals or patients with systemic lupus erythematosus (SLE) or rheumatoid arthritis (RA).⁵It inhibits accumulation of sequestosome-1 (SQSTM1) puncta, a marker of autophagy, in mouse embryonic fibroblasts (MEFs) in a concentration-dependent manner.²Hydroxychloroquine reduces viral titers of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the culture supernatant of infected Vero E6 cells but does not reduce SARS-CoV-2 viral titers in anin vitrohuman airway epithelium model or the respiratory tract of infected cynomolgus macaques.⁴Formulations containing hydroxychloroquine have been used in the prevention or treatment of malaria, as well as in the treatment of RA and SLE.
