“…Another interesting effect caused by quinolines, in particular by chloroquine, is the mobilization of Ca 2+ from compartments within the parasite. 16,17 Since this second messenger is exploited by the parasite to modulate its own life cycle and several other cellular functions, [18][19][20][21] it would not be surprising that a disruption in Plasmodium Ca Notes: Quinine and doxicycline should be administered twice a day, each 12 hours, doxiciclyne and primaquine should not be administered to pregnant women, and primaquine is administered in order to eliminate P. falciparum gametocytes. homeostasis leads eventually to parasite death.…”

“…Chloroquine (CQ) is thought to exert its toxic effect in the intraerythrocytic parasite at the digestive vacuole (14). The compound was also found to induce Ca 2ϩ release and disrupt Ca 2ϩ and H ϩ homeostasis in the cytoplasm of Plasmodium chabaudi cells (15,16). Therefore, with regard to the disruption of intracellular Ca 2ϩ homeostasis, it was hypothesized that the potentiation of CQ activity could be achieved in the malaria parasite with the simultaneous administration of 2-APB.…”

“…No entanto há diversos trabalhos que sugerem a existência desta via em Plasmodium (Elabbadi et al,1994;Enomoto et al, 2012;Hotta et al, 2000;Martin et al, 1994, Raabe et al, 2011. A capacidade dos compartimentos ácidos em amarzenar Ca 2+ foi descrita em Plasmodium Gazarini et al, 2007;Passos et al, 1998), plantas (Ruiz et al, 2001) e Tripanosoma (Huang et al, 2012). Uma das ações da cloroquina em Plasmodium é a alcalinização dos vacúolos ácidos e consequente extrusão de Ca 2+ deste compartimento (Gazarini et al, 2007 O retorno a linha basal indica que a maquinaria celular responsável pela homeostase de Ca 2+ está funcional nas condições testadas neste protocolo.…”
