A series of tetrahydroisoquinoline-N-phenylamide derivatives were designed, synthesized, and tested for their relative binding affinities, and antagonistic activities against estrogen receptor (ER). Compound If (relative binding affinity, RBA = 5) showed higher binding affinity than tamoxifen (R BA = 1), a potent ER antagonist and currently being used for breast cancer therapy. Compound If also exerted optimal antagonistic activity against ER in reporter and cell proliferation assays. Interestingly, compound Ij, which only has a minor agonistic effect against ER, acted as a progesterone receptor (PR) antagonist and exerted agonistic activity against AP-1 through ER pathway. Our results show that these new compounds can be employed as leading pharmacophore for further development of potent selective ER and/or PR modulators or antagonists. (c) 2007 Elsevier Ltd.
