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.

A clinical microbiologist makes serial dilutions of several antimicrobials in broth, and then incubates each drug dilution series with a standard amount. CP-466722 is a potent and reversible ATM inhibitor, does not affect ATR and inhibits PI3K or PIKK family members in cells. ETP-46464 ETP-46464 is a potent and selective inhibitor of ATR with IC50 of 25 nM. FeaturesSelective ATR inhibitor and particularly toxic to p53-deficient cancer cells. 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. 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.

Binding of chloroquine to DNA - ScienceDirect. The lysosomal inhibitor, chloroquine, increases cell surface.. 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. Chloroquine can inhibit a pre-entry step of the viral cycle by interfering with viral particles binding to their cellular cell surface receptor. Chloroquine was shown to inhibit quinone reductase 2, a structural neighbour of UDP-N-acetylglucosamine 2-epimerases that are involved in the biosynthesis of sialic acids. The sialic acids are acidic. 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.
