Malaria is an infectious, often fatal disease that afflicts nearly 200 million people every year. The disease, characterized by recurring and extreme flu-like symptoms, is caused by the protozoan parasite Plasmodium falciparum. Victims usually contract the disease through a mosquito vector. Chloroquine is a chemotherapeutic that was introduced in the 1940s. For many years the drug was the foremost treatment of malaria, being effective and producing few side effects. Unfortunately, tolerance to chloroquine developed when the parasite evolved a resistance mechanism. Newer drugs have been developed and implemented, but these medicines also show a decreasing effect with continued administration. It is imperative that a new pipeline of drugs be developed in order to combat the disease and anticipated resistance. Reversed chloroquines are a new class of multiple-ligand compounds that are active against chloroquine-sensitive and chloroquine-resistance malaria species. This thesis describes research targeted at the modification of lead reversed chloroquine molecules to discover new and effective moieties, as well as to improve pharmacokinetic-related properties. An especial emphasis of this project is the addition of a sulfonamide functional group to a reversed chloroquine. Preliminary evidence indicates that this is a promising direction for this line of research. Brief discussions of some reversed chloroquine characterization studies are included in appendices.
