Endocrine therapies are widely used for the treatment of estrogen-sensitive diseases. 17β-hydroxysteroid dehydrogenase type 1 (17β-HSD1) is involved in the last step of the biosynthesis of potent estrogen estradiol (E2). This enzyme catalyzes the reduction of the C17-ketosteroid estrone (E1) into the C17β-hydroxy steroid E2 using the cofactor NAD(P)H. The X-ray analysis of E2/adenosine bisubstrate inhibitor EM-1745 proven that this compound interacts with both the substrate- and the cofactor…

The design and synthesis of novel 17β hydroxysteroid dehydrogenase inhibitors as anti-cancer agents

It can be tentatively concluded that STX1040 1 acts a mixed site inhibitor for both the E2 and co-factor binding sites and the 2-substituted Mannich compound 127 acts as a competitive inhibitor for the E1 binding site and a non-competitive inhibitor forThe co-Factor binding site, however further experimentation is required to confirm these preliminary results.

Synthesis and Biological Evaluation of Triazolyl 13α-Estrone–Nucleoside Bioconjugates

2′-Deoxynucleoside conjugates of 13α-estrone were synthesized by applying the copper-catalyzed alkyne–azide click reaction (CuAAC) and showed moderate antiproliferative properties against a panel of human adherent cancer cell lines and the protected cytidine conjugate proved to be the most potent.
