Abstract
The invention relates to new amino dimeric naphthoquinone compounds with antileukemic activity. Compounds of the invention demonstrated increased aqueous solubility compared to previously available dimeric naphthoquinones and potent nanomolar inhibition of cell survival in AML cells. Preferred compounds contained an aziridine or a secondary amino alcohol pharmacophore.
