This paper reports the identification and biochemical characterization of the first dual inhibitors targeting steroid sulfatase (STS) and 17β-hydroxysteroid dehydrogenase type 1 (17β-HSD1), using designed multiple-ligand approaches for estrogen-dependent diseases. In human enzyme and cell assays, compounds showed inhibitory activity against 17β-HSD1 measured with [3H]-E1/E1 substrates plus NADH via HPLC-based radio-detection, and against STS in T47D cells (and placental microsomal STS) using [3H]-E1S/E1S substrates, including time-dependent and irreversible inhibition in some STS experiments. A key limitation visible from the provided text is that it largely contains assay-readout fragments (e.g., lists of IC50 values) without full experimental design, compound structures, or in vivo/physiologic outcome context. This paper is centrally about endometriosis-adjacent estrogen-synthesis targets—specifically STS and 17β-HSD1—which are relevant to endometriosis because these enzymes modulate local estrogen availability in endometriotic tissue.

Abstract

STS and 17β-HSD1 are attractive targets for the treatment of estrogen-dependent diseases like endometriosis and breast cancer. The simultaneous inhibition of both enzymes appears more promising than blockage of either protein alone. We describe a designed multiple ligand approach resulting in highly potent dual inhibitors. The most interesting compound 9 showed nanomolar IC50 values for both proteins, membrane permeability, and no interference with estrogen receptors. It efficiently reversed E1S- and E1-induced T47D cell proliferation.
