Unfortunately the parasite has managed to devise mechanisms that allow it to evade the action of almost all the antimalarials in our arsenal. The antifolate drugs include the dihydrofolate inhibitors pyrimethamine and proguanil as well as the sulfones and sulfonamides. These antimalarials act on enzymes in the folate pathway. The mechanism of resistance to these compounds involve mutations in the target enzyme that decrease the affi..
