In order to assess the importance of DNA binding, we have measured the affinity of DNA for chloroquine by equilibrium dialysis using tritiated chloroquine. The dissociation constant of the DNA-chloroquine complex varied from 27 μM to 2.6 m M, depending on the ionic strength of the buffer. Plaquenil vision side effects Hydroxychloroquine lyme disease Chloroquine and its analogs inhibit synthesis of nucleic acids of the parasite by affecting the matrix function of DNA. This happens by preliminary binding of the drug through hydrogen bonds with the purine fragments, and subsequent introduction of the chloroquine molecule between the orderly arranged base pairs into the spirals of the DNA of the parasite. Chloroquine does not inhibit BMP-mediated Smad signalling and transcription of target genes. Since chloroquine inhibits the internalization of BMPR-II, it is possible that signalling downstream of the receptor could be adversely affected by this intervention. In addition, off-target effects of chloroquine might negatively impact BMP signalling. Gold does not influence DNA synthesis or repair, D-penicillamine inhibits DNA-synthesis only. However, Chloroquine and metabolised cyclophosphamide respecitvely impair both DNA-synthesis and repair. This effect may be also caused by azathioprine in high dosage. Application of two repair- inhibitors or of one DNA-repair-inhibitor and one directly mutagenic acting drug, e.g. cyclophosphamide, should therefore be avoided. PMID 1243806 Nevertheless, because of the large number of sites present, binding to parasite DNA may still account for the antimalarial activity of chloroquine. Our results suggest that chloroquine binding to DNA is highly dependent on salt concentration.

The exact mechanism of antimalarial activity of chloroquine has not been determined. The 4-aminoquinoline derivatives appear to bind to nucleoproteins and interfere with protein synthesis in susceptible organisms; the drugs intercalate readily into double-stranded DNA and inhibit both DNA and RNA polymerase. In addition, studies using chloroquine indicate that the drug apparently concentrates in parasite digestive vacuoles, increases the pH of the vacuoles, and interferes with the parasite's. However, in contrast to the β-lactams, the structure of vancomycin is not similar to that of cell-wall peptidoglycan subunits and does not directly inactivate penicillin-binding proteins. Rather, vancomycin is a very large, complex molecule that binds to the end of the peptide chain of cell wall precursors. Chloroquine is also utilised in the treatment of autoimmune diseases. Yet the activity of the molecule is not limited to malaria and the control of inflammatory processes, as illustrated by its broad-spectrum activity against a range of bacterial, fungal and viral infections.
