The goal of selective targeting of enediyne cytotoxins has been investigated using estrogenic delivery vehicles. A series of estrogen-enediyne conjugates were assembled, and affinity for human estrogen receptor [hERalpha] was determined. The most promising candidate induced receptor degradation following Bergman cycloaromatization and caused inhibition of estrogen-induced transcription in T47-D human breast cancer cells.

Enediyneestrogenconjugates have been prepared from readily available precursors. Enediyne 12 causes significant DNA strand scission at 10−3M, and has demonstrated cytotoxicity against the ER rich MCF-7 human breast cancer cell line.
