  Antimycobacterial activity evaluation, time-kill kinetic and 3D-QSAR study of C-(3-aminomethyl-cyclohexyl)-methylamine derivatives

  摘要：

  A series of C-(3-aminomethyl-cyclohexyl)-methylamine derivatives were synthesized and evaluated for their antitubercular activity. Some of the compounds exhibited potent activity against Mycobacterium tuberculosis H37Rv. One of the compound having t-butyl at para position of the benzene ring showed excellent activity even better than the standard drug ethambutol with MIC value 1.1 +/- 0.2 mu M. The time-kill kinetics study of two most active compounds showed rapid killing of the M. tuberculosis within 4 days. Additionally atom-based quantitative structure-activity relationship (QSAR) model was developed that gave a statistically satisfying result (R-2) = 0.92, Q(2) = 0.75, Pearson-R = 0.96 and effectively predicts the anti-tuberculosis activity of training and test set compounds.

• Aqueous Sonogashira coupling of aryl halides with 1-alkynes under mild conditions: use of surfactants in cross-coupling reactions
  作者：Gina M. Roberts、Wenya Lu、L. Keith Woo

  DOI：10.1039/c5ra00505a

  日期：——

  Aqueous Sonogashira coupling between lipophilic terminal alkynes and aryl bromides or iodides gave moderate to high yields at 40 °C using readily available and inexpensive surfactants (2.0 w/v% in water) such as SDS and CTAB. The catalyst precursor was 2 mol% Pd(PPh3)2Cl2, and included a 5 mol% Cu(I) co-catalyst for aryl iodide substrates. Aryl-bromide reagents were found to be inhibited by iodide

  亲脂性末端炔烃与芳基溴化物或碘化物之间的Sonogashira水溶液偶联在40°C下使用容易获得且便宜的表面活性剂（在水中为2.0 w / v％），例如SDS和CTAB，可得到中等至高收率。催化剂前体是2mol％的Pd（PPh 3）2 Cl 2，并且包括用于芳基碘化物底物的5mol％的Cu（I）助催化剂。发现芳基溴化物试剂被碘化物和Cu（I）抑制。在无Cu（I）条件下的研究揭示了两种竞争途径。去质子化途径产生了传统的Sonogashira产物（3），而碳pal化途径产生了烯炔[ 5]。。表面活性剂溶液（SDS或CTAB）最多可循环使用三次，以在CuI存在下在1-辛炔和1-碘庚烷之间偶联，然后降低产率。

  accessible hydrazinoaminocarbene complexes of Pd(II) are shown to be efficient catalysts for copper-free Sonogashira cross-couplings of a variety of aryl iodides with aryl- and alkylalkynes under mild conditions, in ethanol as the solvent and using potassium carbonate as the base. The reactions were carried out with 0.05 mol % of the catalysts which demonstrated exceptional stability in the solid state and
