  • A novel estrogen receptor down-regulator, 7-hydroxycoumarin (5, SS5020), has been reported with antitumor effects against chemically induced mammary tumors. Here, we report on our own investigation of 7-hydroxycoumarins as potential selective estrogen receptor down-regulators, which led us to the discovery of potent down-regulating antagonists, such as 33 ...

    A novel estrogen receptor down-regulator, 7-hydroxycoumarin (5, SS5020), has been reported with antitumor effects against chemically induced mammary tumors. Here, we report on our own investigation of 7-hydroxycoumarins as potential selective estrogen receptor down-regulators, which led us to the discovery of potent down-regulating antagonists, such as 33. Subsequent optimization and removal of the 7-hydroxy group led to coumarin 59, which had increased potency and improved rat bioavailability relative to SS5020.
