Cycloguanil is an inhibitor of dihydrofolate reductase (DHFR)[1].
Dihydrofolate reductase (DHFR) is an enzyme that involved in reducing dihydrofolic acid to tetrahydrofolic acid. DHFR plays a critical role in regulating the amount of tetrahydrofolate in the cell, which are essential for purine and thymidylate synthesis important for cell proliferation and cell growth. DHFR also plays a central role in the synthesis of nucleic acid precursors and salvage of tetrahydrobiopterin from dihydrobiopterin [2].
Cycloguanil is the active metabolite of proguanil produced by the cytochrome P450 (CYP) [3]. Cycloguanil showed activity against P. falciparu. Cycloguanil inhibited the activity of dihydrofolate reductase (DHFR) with the Ki values of 0.3 and 1.5 nM for Plasmodium and human forms, respectively., Cycloguanil prevented the production of tetrahydrofolic acid, an essential coenzyme involved in DNA and RNA synthesis, by blocking DHFR activity.
