title: Inhibitory effects of fluorine-substituted estrogens on the activity of 17beta-hydroxysteroid dehydrogenases.
abstract: In search for new inhibitors of human 17beta-hydroxysteroid dehydrogenase type 1 (h17beta-HSD1) a specific group of steroids with interesting properties including novel compounds was investigated. Several estratriene derivatives with fluorine-substitution in position 17 of the steroidal scaffold were synthesised and tested in vitro towards recombinant h17beta-HSD1, 2, 4, 5 and 7. Moderate, mostly unselective inhibitors of h17beta-HSD1 and h17beta-HSD2 and a selective inhibitor of h17beta-HSD5 were identified. The structure-activity relationship with respect to inhibitory strengths and selectivity of these compounds on five h17beta-HSDs is discussed.
