Abstract The syntheses of various analogs of the minor groove binding agent Hoechst33258 I are described to explore their potential of selective helicase blockade and anticancer activity. The target compounds II a,b,c and III a,b,c were obtained by condensation of the appropriate functionalized ortho-diamines and substituted benzimidazole carboxaldehydes in nitrobenzene.

Disclosed are methods of using various compounds, which are known to bind to 3-deoxyglucosone (3DG) or precursors thereof, in order to reduce a susceptibility to tumor formation and/or to prevent or delay onset of tumor formation induced by 3DG and its precursors. Also disclosed is the reduction of 3DG levels in high fructose corn syrop so that the high fructose corn syrup is less likely to induce tumor formation.

Whole-cell high-throughput screening of the AstraZeneca compound library against the asexual blood stage of Plasmodium falciparum (Pf) led to the identification of amino imidazoles, a robust starting point for initiating a hit-to-lead medicinal chemistry effort. Structure-activity relationship studies followed by pharmacokinetics optimization resulted in the identification of 23 as an attractive lead with good oral bioavailability. Compound 23 was found to be efficacious (ED90 of 28.6 mg.kg(-1)) in the humanized P. falciparum mouse model of malaria (Pf/SCID model). Representative compounds displayed a moderate to fast killing profile that is comparable to that of chloroquine. This series demonstrates no cross-resistance against a panel of Pf strains with mutations to known antimalarial drugs, thereby suggesting a novel mechanism of action for this chemical class.
