Chloroquine Diphosphate Description

Chloroquine Diphosphate salt is a member of the quinolone family and a lysosomotropic agent (accumulate inside the acidic parts of the cell). This accumulation leads to inhibition of lysosomal enzymes that require an acidic pH, and prevents fusion of endosomes and lysosomes. Recently, chloroquine phosphate, an antimalarial drug with a history of more than 70 years, has become one of the most potentially effective drugs for the treatment of SARS-CoV-2.

Chloroquine diphosphate is an antimalarial drug. Inhibits cell growth and induces cell death in numerous cancer cell lines.
