Designed Enediyne Antitumor Agents

Pp. 189-214 (26)

Abstract

The enediynes remain among the most potent antitumoral agents to have been discovered in the past decade. Following prodrug activation, the enediynes undergo cycloaromatization reactions resulting in formation of highly reactive diradical intermediates. The diradical species engage in atomtransfer chemistry to produce neutral arene products, in the process inducing damage to key macromolecules. Several of the naturally occurring members of the enediyne family of antibiotics have entered clinical trials, and this has prompted the design of synthetic enediynes, where the enediyne 'warhead' is conjugated to a targeted delivery vehicle. This review will describe ecent efforts using chemical synthesis to identify and improve the target specificity of designed enediynes, and to establish efficient methods to achieve prodrug activation. Finally, new horizons will be examined, including the use of post-cycloaromatized enediyne templates as recognition elements for unique DNA and RNA microenvironments.
