Targeting the uprising of malarial resistance

8 Setembro 2010

A new class of drugs holds the promise to control multidrug-resistant malaria causing microbes. A report of a joint team of collaborators from USA, Switzerland, Singapore and Thailand.
Abstract:
Recent reports of increased tolerance to artemisinin derivatives—the most recently adopted class of antimalarials—have prompted a need for new treatments. The spirotetrahydro-β-carbolines, or spiroindolones, are potent drugs that kill the blood stages of Plasmodium falciparum and Plasmodium vivax clinical isolates at low nanomolar concentration. Spiroindolones rapidly inhibit protein synthesis in P. falciparum, an effect that is ablated in parasites bearing nonsynonymous mutations in the gene encoding the P-type cation-transporter ATPase4 (PfATP4). The optimized spiroindolone NITD609 shows pharmacokinetic properties compatible with once-daily oral
dosing and has single-dose efficacy in a rodent malaria model.
