(e) 4 hydroxytamoxifen

(E)-4-Hydroxytamoxifen is a less active isomer of (Z)-4-hydroxytamoxifen and also is an estrogen receptor modulator.

(E Z)-4-Hydroxytamoxifen (Afimoxifene) is a novel estrogen inhibitor, commonly used in research for various estrogen-dependent conditions, including cyclic mastalgia and gynecomastia.

Isoerysenegalensein E shows anti-estrogenic activity comparable to that of 4-hydroxytamoxifen, a typical estrogen receptor antagonist. It shows significant cytotoxicity against HL-60 cells, it induces apoptosis in HL-60 cells through activation of the cas
