Chloroquine then synthesis of chloroquine mechanism becomes protonated (to CQ2+), as the digestive vacuole is known to be acidic (pH 4.7); chloroquine then cannot leave by diffusion. Chloroquine is a synthetic form of quinine, a compound found in the bark of cinchona trees native to Peru and used for centuries to treat malaria. Nalidixic acid selectively inhibits the activity of bacterial DNA gyrase, blocking DNA replication Chloroquine phosphate: 515.87 Mechanism of action/Effect: Antiprotozoal—Malaria: Unknown, but may be based on ability of chloroquine to bind to and alter the properties of DNA. Action of the toxic FP-chloroquine and FP results in cell lysis and ultimately parasite cell autodigestion. The heme moiety consists of a porphyrin ring called Fe(II)-protoporphyrin IX (FP). The synthetic derivatives chloroquine, quinacrine (also called mepacrine), and mefloquine are commonly used as antimalarials, and chloroquine is also used to treat amebiasis typically caused by Entamoeba histolytica.
