Orally bioavailable SERDs may offer greater systemic drug exposure, improved clinical efficacy, and more durable treatment outcome for patients with ER-positive endocrine-resistant breast cancer. We report the design and synthesis of a boronic acid modified fulvestrant (5, ZB716), which binds to ER alpha competitively (IC50 = 4.1 nM) and effectively downregulates ERa in both tamoxifen-sensitive and tamoxifen-resistant breast cancer cells. Furthermore, It has superior oral bioavailability (AUC = 2547.1 ng-h/mL) in mice, indicating its promising clinical utility as an oral SERD.
