we discovered estrogenreceptor (ER) ligands with a novel three‐dimensional oxabicyclo[2.2.1]heptene corescaffold and good ER binding affinity act as partial agonists via small alkyl ester substitutions on the bicyclic core that indirectlymodulate the critical switch helix in the ER ligandbinding domain, helix 12, by interactions with helix 11. This contrasts with the mechanism of action of tamoxifen

and activities, we have explored compounds in which the central hydrophobic core has a more three-dimensional topology than typically found in estrogen ligands and thus exploits the unfilled space in the ligand-binding pocket. Here, we build upon our previous investigations of 7-oxabicyclo[2.2.1]heptene core ligands, by replacing the oxygen bridge with a sulfoxide. These new 7-thiabicyclo[2.2.1]hept-2-ene-7-oxides
Identification of Novel Dual-Target Estrogen Receptor α Degraders with Tubulin Inhibitory Activity for the Treatment of Endocrine-Resistant Breast Cancer
Endocrine resistance remains a significant problem in the clinical treatment of estrogen receptor α-positive (ERα+) breast cancer (BC). In this study, we developed a series of novel dual-functional ERα degraders based on a bridged bicyclic scaffold with selenocyano (SeCN) side chains. These compounds displayed potent ERα degradation and tubulin depolymerization activity. Among them, compounds 35s and
