A small set of novel 2,N6-disubstituted 1,2-dihydro-1,3,5-triazine-4,6-diamines was prepared possessing a flexible tether between the exocyclic nitrogen bonded to C-6 of the 1,2-dihydro-1,3,5-triazine-4,6-diamine heterocycle and the distal aryl ring. Three zones were varied in this series of compounds, namely the nature of the substituent(s) on C-2; the nature of the substituent(s) on the distal aryl ring; as well as the nature and length of the flexible tether between the rings. The compound showing the best antimalarial activity (cycloguanil-resistant FCR-3 Plasmodium falciparum IC50=0.99 μM) was N6-(3-(4-chlorophenoxy)propyl)-2-(furan-2-yl)-1,2-dihydro-1,3,5-triazine-4,6-diamine hydrochloride.
