The aromathecin topoisomerase I (top1) inhibitors offer promising scaffolds for the development of novel cancer chemotherapeutics. They are 'composites' of the camptothecin and indenoisoquinoline top1 inhibitors. Interestingly, some structure-activity relationship (SAR) overlap between the aromathecins and the indenoisoquinolines has been observed. For both classes, placement of certain polar groups in similar regions of the heteroaromatic system improves top1 inhibitory and antiproliferative activities. A series of water-soluble aromathecins substituted at position 14 with diaminoalkanes of various lengths has been prepared. These compounds all possess similar antiproliferative potency, but a general trend is observed: aromathecins with longer diaminoalkane substituents (>6 carbons) possess lower anti-top1 activity than their smaller counterparts (2-4 carbons), presumably as a result of unfavorable hydrophobic interactions. This trend is also noted with the indenoisoquinolines, revealing additional SAR overlap that supports the hypothesis that there is a 'universal' top1 inhibitor SAR. (C) 2009 Elsevier Ltd.

The synthesis of aromathecins, substituted 12H-5,l la-diazadibenzo[b,h]fluoren- 11 -ones is described. Use of these cytotoxic compounds and pharmaceutical compositions containing them for the treatment of cancer is described. Two novel processes for the synthesis of this system and a series of 14-substituted aromathecins as novel cytotoxic, topoisomerase I poisons are described.
