title: Estradiol dimers as a new class of steroid sulfatase reversible inhibitors.
abstract: A series of estradiol dimers was synthesized or selected from compounds available in our laboratory and tested for inhibition against steroid sulfatase. Dimers linked by their C17 position, compounds 7 and 8, showed inhibitory potency similar (56% and 54% at 1 microM) to that of our best previously reported reversible inhibitor EM-690 (62% at 1 microM). Docking experiment seems to indicate that C17-C17 dimers bind in a similar way to EM-690 whereas C16-O3 and C16-C16 dimers bind in an upside-down position.
