    Chloroquine protein synthesis


    Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance. It is recommended to check if chloroquine is still effective in the region prior to using it.

    Did not also affect protein synthesis. Chloroquine caused significant cell death at concentrations above 0.2 mmol/l in this protein-free medium, i.e. in the concentration range needed for maximal inhibition of protein degradation. 6. Incubation of hepatocytes under anoxic conditions resulted in an inhibition of protein The drug chloroquine is bactericidal for Bacillus megaterium ; it inhibits DNA and RNA biosynthesis and produces rapid degradation of ribosomes and dissimilation of ribosomal RNA. Inhibition of protein synthesis is also observed, evidently as a secondary effect. Inhibition of DNA replication is proposed as a general mechanism of the antimicrobial action of chloroquine. 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.

    The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations. In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead.

  3. Instead, they seem to interfere with formation of the initiation complex association of the 50S subunit, 30S subunit, and other factors for translation, and they prevent translocation of the growing protein from the ribosomal A site to the P site. Table 3 summarizes the protein synthesis inhibitors.

    The heme-chloroquine interactive effects can also be demonstrated with purified eIF-2 alpha kinase from rabbit reticulocyte lysate. It is proposed that chloroquine inhibits heme-dependent protein synthesis in the parasite and this is an early event mediating the growth-inhibitory effects of the drug. Rapid turnover of BMPR-II can be inhibited by chloroquine treatment. A Protein synthesis in human PAECs was inhibited by cycloheximide treatment 20 μg/ml. Protein expression was assessed after protein synthesis blockade over a time course of 0, 0.5, 1, 2, 4 h. Sep 15, 2009 We report the synthesis and in vitro antimalarial activity of several new 4-amino-and 4-alkoxy-7-chloroquinolines carrying a linear dibasic side chain. Many of these chloroquine analogues have submicromolar antimalarial activity versus HB3 chloroquine.
