    Chloroquine does not inhibit dna synthesis

    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.

    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. However, a conclusive link between DNA binding and the antimalarial ac- tion of chloroquine has not been made. A better case for this mechanism can be made if significant binding of chloroquine to DNA oc- curs at therapeutic concentrations of the drug. 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.

    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.

  4. Chloroquine inhibits the heme-dependent protein synthesis in the parasite lysate. The drug has also been found to inhibit parasite protein synthesis in situ at therapeutic concentrations soon after addition to parasite cultures. Ribosomes as well as the S-100 fraction isolated from such chloroquine-treated cultures are defective in protein synthesis.

    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. III. Also inhibit DNA and RNA response and synthesis. Uses. 1. Main use is as anti-malarial. Highly effective for blood schizonticides. Mostly only sensitive for P. falciparum, as most strains are resistant now. Used usually to resolve febrile illness within 24-48 hours, if does not improve, then strain is resistant. Chloroquine is a 9-aminoquinoline known since 1934. Apart from its well-known antimalarial effects, the drug has interesting biochemical properties that might be applied against some viral infections. Chloroquine exerts direct antiviral effects, inhibiting pH-dependent steps of the replication of several viruses including members of the flaviviruses, retroviruses, and coronaviruses. Its best.
