  Arylamino methylene bisphosphonate derivatives as bone seeking matrix metalloproteinase inhibitors

  摘要：

  The complexity of matrix metalloproteinase inhibitors (MMPIs) design derives from the difficulty in carefully addressing their inhibitory activity towards the MMP isoforms involved in many pathological conditions. In particular, specific metalloproteinases, such as MMP-2 and MMP-9, are key regulators of the 'vicious cycle' occurring between tumor metastases growth and bone remodeling. In an attempt to devise new approaches to selective inhibitor derivatives, we describe novel bisphosphonate bone seeking MMP inhibitors (BP-MMPIs), capable to be selectively targeted and to overcome undesired side effects of broad spectrum MMPIs.In vitro activity (IC50 values) for each inhibitor was determined against MMP-2, -8, -9 and -14, because of their relevant role in skeletal development and renewal. The results show that BP-MMPIs reached IC50 values of enzymatic inhibition in the low micromolar range. Computational studies, used to rationalize some trends in the observed inhibitory profiles, suggest a possible differential binding mode in MMP-2 that explains the selective inhibition of this isoform.In addition, survival assay was conducted on J774 cell line, a well known model system used to evaluate the structure-activity relationship of BPs for inhibiting bone resorption. The resulting data, confirming the specific activity of BP-MMPIs, and their additional proved propensity to bind hydroxyapatite powder in vitro, suggest a potential use of BP-MMPIs in skeletal malignancies.

  A facile synthesis of aminomethylene bisphosphonates catalyzed by ytterbium perfluorooctanoate under ionic liquid condition

  摘要：

  Three-component reactions of amines, triethylorthoformate and diethyl phosphite are efficiently catalyzed by ytterbium perfiuorooctanoate [Yb(PFO)(3)] in 1-butyl-3-methylimidazolium chloride ([bmim][Cl]) ionic liquid, giving the corresponding aminomethylene bisphosphonates in good yields. The catalyst can be recovered and reused for several times without any significant loss of activity. (C) 2011 Elsevier B.V. All rights reserved.

  The preparation and description of a novel secondary amine ionic liquid, di-n-butyl ammonium chlorosulfonate, is described. The di-n-butyl ammonium ionic liquid (DBA IL) was characterized by FT-IR, elemental analysis, NMR spectroscopies, and wide-angle X-ray scattering techniques, as well as thermogravimetric analysis. The DBA IL functions as an efficient, environmentally benign, and recyclable catalyst with short reaction times and high catalytic activity for the synthesis of a variety of N-containing bisphosphonates in high yields. Another merit of this ionic liquid shown that the purification of products by non-chromatographic method with good to excellent yields of the desired products. (C) 2014 Elsevier B.V.
