Cycloguanil is a dihydrofolate reductase inhibitor and is a metabolite of the antimalarial drug proguanil. The parent drug proguanil was suggested to contribute to the antimalarial activity as well, but the mechanism of action is unknown. Proguanil is a prodrug that is metabolized to its main active metabolite, cycloguanil, mostly via CYP2C19. There is significant variation in proguanil pharmacokinetics.12 CYP2C19 is the predominant enzyme catalyzing the bioactivation of proguanil to cycloguanil. Cycloguanil is one of the few antimalarial drugs that act on both the erythrocytic and on the pre-erythrocytic (hepatic) forms of the malaria parasites. Although cycloguanil is not currently in general use as an antimalarial, the continuing development of resistance to current antimalarial drugs has led to renewed interest in studying the use of cycloguanil in combination with other drugs.
