Key to the expression of the malaria disease-state is a pathway by which the parasite, Plasmodium, protects itself from heme toxicity. Our research program is designed to explore this process through the use of model chemical systems and to design approaches to overcome this self-protection - leading to effective, long-lasting treatment of the disease. In particular, we plan to determine: (i) the mechanism by which hemin is converted into the malaria pigment (hemozoin), (ii) the molecular details of how chloroquine and related drugs interfere with this process, (iii) the chemical factors that contribute to drug resistance by the Plasmodium parasite, and (iv) methods to neutralize this resistance.
