A furoxan-amodiaquine hybrid as a potential therapeutic for three parasitic diseases().

ABSTRACT

Parasitic diseases continue to have a devastating impact on human populations worldwide. Lack of effective treatments, the high cost of existing ones, and frequent emergence of resistance to these agents provide a strong argument for the development of novel therapies. Here we report the results of a hybrid approach designed to obtain a dual acting molecule that would demonstrate activity against a variety of parasitic targets. The antimalarial drug amodiaquine has been covalently joined with a nitric oxide-releasing furoxan to achieve multiple mechanisms of action. Using in vitro and ex vivo assays, the hybrid molecule shows activity against three parasites - Plasmodium falciparum, Schistosoma mansoni, and Ancylostoma ceylanicum.
