containing a tetracyclic benzopyranobenzoxepine scaffold, which were reported as potent selective estrogen receptor modulators (SERMs). Incorporation of a fluoromethyl azetidine side chain yielded highly potent and efficacious selective estrogen receptor degraders (SERDs), such as 16aa and surprisingly, also its enantiomeric pair 16ab. Co-crystal structures of the enantiomeric pair 16aa and 16ab in complex
尽管在了解ERα信号通路和获得许多治疗药物的认可方面取得了巨大进展,但ER +乳腺癌仍然是女性癌症死亡的主要原因。我们着手发现具有双重作用机制的化合物,其中它们不仅与雌二醇竞争与ERα的结合,而且还可以诱导ERα蛋白本身的降解。我们被包含四环苯并吡喃并苯并xepine支架的约束色酮所吸引,据报道它们是有效的选择性雌激素受体调节剂(SERMs)。氟甲基氮杂环丁烷侧链的掺入产生了高效且有效的选择性雌激素受体降解剂(SERD),例如16aa,并且还令人惊讶地是其对映体对16ab。
