    Heme chloroquine complex


    Chloroquine is able to bind to DNA, and inhibit DNA replication and RNA synthesis which in turn results in cell death. The effect of Chloroquine may also be related to the formation of a toxic heme-Chloroquine complex.

Chloroquine is able to bind to DNA, and inhibit DNA replication and RNA synthesis which in turn results in cell death. The effect of Chloroquine may also be related to the formation of a toxic heme-Chloroquine complex. Heme is a ferro-proto-porphyrin. Heme = Protoporphyrin IX ring + Iron Fe in center Protoporphyrin IX = porphyrin with attachment to 4 Methyl, 2 Propionyl and 2 Vinyl groups. Porphyrin = Cyclic

    Chloroquine possesses definite antirheumatic properties. Chloroquine has immuno-modulatory effects, suppressing the production/release of tumour necrosis factor and interleukin 6. Chloroquine inhibits trophozoite hemoglobin degradation through increasing vacuolar p H and inhibiting the activity of vacuolar phospholipase, vacuolar proteases, and heme polymerase.

  3. Chloroquine forms a drug-hemozoin complex, and this complex caps the polymerizing chain, thereby preventing additional polymerization. Along with the prevention of polymerization, the free heme accumulates in the food vacuole, exerting its toxic effects on the parasite. Chloroquine also functions as an anti-autoimmune therapy.

    Polysaccharide iron complex Iferex 150, Ferrex 150, Niferex 150 is a prescription medication used to prevent or treat anemia. Side effects, drug interactions, dosage, storage, and pregnancy safety information should be reviewed prior to taking this medication. Further studies using equilibrium dialysis determined that the affinity of chloroquine for ferric heme is high Kd = 3.5 nM at pH 7.4 and that the complex contains 2 mol heme to 1 mol chloroquine Chou et al. 1980. In support of this, Balasubramanian et al. 1984 have obtained spectral evidence that a chloroquine-heme complex forms/n situ inside chloroquine treated trophozoites. Sugioka et al. 1987 have also shown that a chloroquine-heme complex is more potent at promoting lipid peroxidation than free heine alone.
