  Dual Aromatase−Steroid Sulfatase Inhibitors

  摘要：

  By introducting the steroid sulfatase inhibitory pharmacophore into aromatase inhibitor 1 (YM511), two series of single agent dual aromatase-sulfatase inhibitors (DASIs) were generated. The best DASIs in vitro (JEG-3 cells) are 5, (IC50(aromatase) = 0.82 nM; IC50(sulfatase) = 39 nM), and 14, (IC50(aromatase) = 0.77 nM; IC50(sulfatase) = 590 nM). X-ray crystallography of 5, and docking studies of selected compounds into an aromatase homology model and the steroid sulfatase crystal structure are presented. Both 5 and 14 inhibit aromatase and sulfatase in PMSG pretreated adult female Wistar rats potently 3 h after a single oral 10 mg/kg dose. Almost complete dual inhibition is observed for 5 but the levels were reduced to 85% (aromatase) and 72% (sulfatase) after 24 h. DASI 5 did not inhibit aldosterone synthesis. The development of a potent and selective DASI should allow the therapeutic potential of dual aromatase-sulfatase inhibition in hormone-dependent breast cancer to be assessed.

  Latent ruthenium initiators containing fluoro aryloxide ligands

  摘要：

  A new ligand, methyl 2,3,5,6-tetrafluoro-4-oxybenzoate (C8H3F4O3), combining an electron withdrawing group (C6F4) to tune the reactivity with an anchor group (CO2Me) for immobilization on supports, was used to prepare four new ruthenium initiators, viz. Ru(C8H3F4O3)(2)(-CHPh)(3-Br-C5H5N)(H(2)IMes) and Ru(C8H3F4O3)(2)XL, where X = C,N-(=CHCH2CH2-2-C5H4N) and L = (PPr3)-Pr-i, PCy3 or H(2)IMes. The new ligand greatly reduced the reactivity of the ruthenium centre at room temperature. The H-1 NMR and DSC investigation for the ROMP of norbornene dicarboximide monomers clearly demonstrated that the Ru (C8H3F4O3)(2)XL initiators were inactive at room temperature and required elevated temperatures for their activation.
