The original compound bearing the coplanar quinone and imidazole systems, 2-chloromethyl-4,9-dihydro-1-methyl-1H-naphtho[2,3-d] imidazol-4,9-dione reacted with various nitronate anions to afford, in moderate to rood yields, new naphtho- imidazolediones bearing a trisubstituted ethylenic double bond at the 2-position. These compounds were evaluated as potential antiprotozoan agents. Some derivatives were found to have a significant activity, but the naphthoquinone was found to be a less efficient pharmacophore than the nitro group.

Here we report the nanomolar potencies of N1,N3-dialkyldioxonaphthoimidazoliums against asexual forms of sensitive and resistant Plasmodium falciparum. Activity was dependent on the presence of the fused quinone-imidazolium entity and lipophilicity imparted by the N1/N3 alkyl residues on the scaffold. Gametocytocidal activity was also detected, with most members active at IC50 1 μM. A representative analog with good solubility, limited PAMPA permeability, and microsomal stability demonstrated oral efficacy on a humanized mouse model of P. falciparum.
