    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.

    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. The influence of chloroquine on protein synthesis in rabbit retina has been studied. It is shown that chloroquine inhibits rhodopsin synthesis and the renewal of rod outer segment membranes. Are defective in protein synthesis. Addition of hemin plus glucose 6-phosphate or high concentrations of GTP, cAMP, and an active preparation of eIF-2 to the parasite cell-free system restores protein synthesis to a sigfant extent in chloroquine-treatedcultures. Underconditionsofinhibitionof protein synthesis in situ by chloroquine in the.

    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.

    Leupeptin, on the other hand, was the only degradation inhibitor which 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 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. 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.
