Molecular Design, Synthesis, and Evaluation of SNIPER(ER) That Induces Proteasomal Degradation of ERα

  • Protocol
Estrogen Receptors

Abstract

Manipulation of protein stability using small molecules has a great potential for both basic research and clinical therapy. Based on our protein knockdown technology, we recently developed a novel small molecule SNIPER(ER) that targets the estrogen receptor alpha (ERα) for degradation via the ubiquitin–proteasome system. This chapter describes the design and synthesis of SNIPER(ER) compounds, and methods for the evaluation of their activity in cellular system.
