Application

Cycloguanil hydrochloride is suitable for use as a positive control in screening Plasmodium falciparum strains in microdilution radioisotope antiplasmodial bioassay. It may also be used as internal standard in high performance liquid chromatography for the quantification of urine and plasma samples.

Biochem/physiol Actions

Cycloguanil is it a potential antimalarial drug. It is hydrophilic in nature. Cycloguanil acts as a substrate for the enzyme organic cation transporter 1 (OCT1).
Cycloguanil, a metabolite of proguanil, is a potent dihydrofolate reductase inhibitor.
