    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.

    Chloroquine is a lysosomotropic agent as it is usually prepared as a diprotic weak base pKa 8.5. The unprotonated form of chloroquine preferentially accumulates in lysosomes as it rapidly diffuses across cell/organelle membranes. 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.

    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.
