estrone into biologically active estradiol. In this study, a library of fused (di)cycloalkeno thieno[2,3-d]pyrimidin-4(3H)-one based compounds was synthesized, and the biological activities against 17β-HSD1 in a cell-free and in a cell-based assay were evaluated. Several thieno[2,3-d]pyrimidin-4(3H)-one based compounds, at 0.1 and 1 μM test concentrations, were found to be potent 17β-HSD1 inhibitors.
