Proguanil hydrochloride

Description: Proguanil hydrochloride (Chloroquanil) is a biguanide compound which metabolizes in the body to form cycloguanil, an anti-malaria agent.Upon hydrolysis, Proguanil hydrochloride is converted to its active cyclic triazine metabolite, cycloguanil, by a cytochrome P450 dependent reaction. Cycloguanil selectively inhibits the bifunctional dihydrofolate reductase-thymidylate synthase of plasmodium parasite, thereby disrupting deoxythymidylate synthesis and ultimately blocking DNA and protein synthesis in the parasite. Target: Antifolate, DNA/RNA Synthesis, Parasite, Dehydrogenase, Others. Smiles: Cl.Clc1ccc(NC(=N)NC(=N)NC(C)C)cc1. References: Gerlinde F. Plöger, etal.
