quinazoline alkaloid isolated from Dichroa febrifuga roots, shows powerful antimalarial activity against Plasmodium falciparum. Although the use of ferifugine as an antimalarial drug has been precluded because of its severe side effects, its potent antimalarial activity has stimulated medicinal chemists to pursue its derivatives instead, which may provide valuable leads for novel antimalarial drugs.

The present invention relates to 2,3-diarylquinazolinone compounds that are useful for treating cellular proliferative diseases, for treating disorders associated with KSP kinesin activity, and for inhibiting KSP kinesin. The invention also related to compositions which comprise these compounds, and methods of using them to treat cancer in mammals.
The ozonation of substituted 2-thiouracils and pyrimidine-2-thione is reported; this provides a new method for the synthesis of several pyrimidine derivatives.
Ozone and 3,3-dimethyl-1,2-dioxirane react with substituted 2-thiouracils and pyrimidine-2-thione to afford several interesting desulfurized products. The effect of the solvent, protic as opposed to nonprotic, on the course of oxidation was striking.
