Image: Esperamicin A1—an enediyne—binds to DNA immediately prior to activation of its
Enediynes are naturally occurring molecules commonly called biological warheads for their ability to bind to and split tumor's DNA backbones. A team of undergraduate physical, biological, and computational chemists at New York's Hamilton College have been studying this mechanism in the hopes of making this a more viable cancer treatment. Computations were performed on the National Center for Supercomputing Applications (NCSA) SGI Origin2000 supercomputer, purchased primarily with funds from the National Science Foundation. [Structure comes from R.A. Kumar, N. Ikemoto, and D. J. Portel, J. Mol. Biol, 265 173-186 (1997).] [See also, Model of Esperamicin A1 Image 1 and Image 3.] Thumbnail">
