Design and synthesis of estrogen receptor degradation inducer based on a protein knockdown strategy

We designed and synthesized estrogen receptor (ER) degradation inducers 5, 6, and 7, which crosslink the ER and the cellular inhibitor of apoptosis protein 1 (cIAP1). Compounds 5, 6, and 7 induced cIAP1-mediated ubiquitylation of ERα resulting in its proteasomal degradation.
