Protein-Degrading Enediynes: Library Screening of Bergman Cycloaromatization Products
摘要:
A screening method based on Bergman cycloaromatization products was applied to a compact library of estrogenic-enediyne hybrids, An enediyne candidate identified from the screen was subsequently synthesized, and it induced temperature- and concentration-dependent degradation of human estrogen receptor a upon cycloaromatization.
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.
