activity against even unknown targets, and thus provides an excellent complement to structural biology. Methyl scanning was applied to demethylasterriquinone B1, a small-molecule mimetic of insulin. A new, optimal totalsynthesis of this natural product was developed that enables the family of methyl scan derivatives to be concisely prepared for evaluation in a cellular assay. The results of this experiment
by the acid-catalyzed condensation of Indoles with 2,5-dichiorobenzoquinone, followed by DDQoxidation. The resulting dichloroquinones are hydrolyzed to the 3-indolyidihydroxybenzoquinones. The 3-indolylquinone substructure is of interest because of its presence in naturalproducts that modulate biological processes through protein-protein interactions, including the asterriquinones.
Pyrrolylquinones and indolylquinones useful for treating diseases such as neurodegenerative disease, viral infections and proliferative disease are described, along with methods of making such compounds and pharmaceutical formulations containing such compounds.
