Inhibition of Plasmodium falciparum pH regulation by small molecule indole derivates results in rapid parasite death

Van Schalkwyk, Donelly; Chan, Xie; Misiano, Paola; Gagliardi, Stefania; Farina, Carlo; Saliba, Kevin

Description

The V-type H+-ATPase is critical during the intraerythrocytic stage of the human malaria parasite Plasmodium falciparum. It is responsible for maintaining a near-neutral cytosolic pH (pH 7.3), an acidic digestive vacuole (pH 4.5-5.5) and the generation of an inside-negative plasma membrane potential (∼-95 mV). Inhibition of this pump is therefore likely to result in profound physiological disturbances within the parasite and parasite death, as illustrated previously by the antiplasmodial...[Show more]
