    Pka of chloroquine


    It accumulates inside the acidic parts of the cell, including endosomes and lysosomes. This accumulation leads to inhibition of lysosomal enzymes that require an acidic p H, and prevents fusion of endosomes and lysosomes. TLR7/8-Mediated Activation of Human NK Cells Results in Accessory Cell-Dependent IFN- Production.

    Upon entry into the digestive vacuole, chloroquine become protonated due the acidic nature of the vacuole and this prevents chloroquine from leaving the vacuole via simple diffusion. The drug then mediates its plasmodicidal effect by capping hemozoin molecules to prevent further biocrystallization of heme, leading to heme buildup. Feb 09, 2018 In this video, I will explain into one of the main antimalarial drug, chloroquine. Chloroquine is a medication used to prevent and to treat malaria in areas where malaria is known to be sensitive. An aminoquinoline that is quinoline which is substituted at position 4 by a 5-diethylaminopentan-2-ylamino group at at position 7 by chlorine.

    Moreover, Chloroquine inhibits autophagy as it raises the lysosomal p H, which leads to inhibition of both fusion of autophagosome with lysosome and lysosomal protein degradation [4]. Chloroquine is commonly used to study the role of endosomal acidification in cellular processes [2, 3], such as the signaling of intracellular TLRs.
