Abstract

The drugs 2,4-diamino-6-(2-naphthyl-sulfonyl)-quinazoline (WR 158,122)and its tetrahydro analog (WR 180,872) were found to act synergistically in reducing the parasitemia of Plasmodium berghei infected mice. Evidence was found that both the drugs which are potent folic acid antagonists were acting at different sites in the folic acid metabolic pathway, neither of which was at the action site of p-aminobenzoic acid (PABA)inhibitors. Advantages of drug combinations in malaria chemotherapy are discussed.
