    Novel and Potent 17β-Hydroxysteroid Dehydrogenase Type 1 Inhibitors
    摘要:
    Structure-based drug design using the crystal structure of human 17 beta-hydroxysteroid dehydrogenase type 1 (17 beta-HSD1) led to the discovery of novel, selective, and the most potent inhibitors of 17 beta-HSD1 reported to date. Compounds 1 and 2 contain a side chain with an m-pyridylmethylamide functionality extended from the 16 beta position of a steroid scaffold. A mode of binding is proposed for these inhibitors, and 2 is a steroid-based 17 beta-HSD1 inhibitor with the potential for further development.

    vitro. Investigation of the SAR reveals that a sterically unhindered hydrogen bond acceptor attached to C-17 is most likely key to the enhanced activity. Compound 8 displayed significant in vitro antiangiogenic activity, and its ability to act as a microtubule disruptor was confirmed. Inhibitory activity of the sulfamate derivatives against steroid sulfatase and carbonic anhydrase II (hCAII) was also

    cells lines (GI(50) of 340-850 nM) could be retained when the heterocyclic substituent possesses H-bond acceptor properties. A good correlation between the calculated electron density of the heterocyclic ring and anti-proliferative activity was observed. Docking of the most active compounds into their putative site of action, the colchicine binding site of tubulin, suggests that they bind through a
