Synthesis, Biochemical Evaluation and Rationalisation of a Series of 3,5- Dibromo Derivatives of 4-Hydroxyphenyl Ketone-Based Compounds as Probes of the Active Site of Type 3 of 17β-Hydroxysteroid Dehydrogenase (17β-HSD3) and the Role of Hydrogen Bonding Interaction in the Inhibition of 17β-HSD3

We report the synthesis, evaluation and rationalisation of the inhibitory activity of a series of 3,5-dibromo derivatives of 4-hydroxyphenyl ketone as probes of the active site of the type 3 of 17β-hydroxysteroid dehydrogenase (17β-HSD3). The results support the important role of hydrogen bonding interaction in the inhibition of 17β-HSD3.
