  Synthesis and antimicrobial activity of imidazole and pyridine appended cholestane-based conjugates

  摘要：

  A series of 3 alpha-amino-5 alpha-cholestane and 3 alpha,7 alpha-diamino-5 alpha-cholestane derivatives containing imidazole and pyridine rings were synthesized by simple and effective reductive amination, and their in vitro activities against a range of Gram-positive and Gram-negative strains were evaluated. Most of the compound exhibited enhanced activity against MRSA pathogen. 3 alpha,7 alpha-Di(pyridylmethyl)amino-5 alpha-cholestane 10 showed the highest potency in these series toward the Gram-positive bacteria, Staphylococcus epidermidis 887E, with the lowest MIC value of 1 mu g/mL.

  New 2-aminoethylimidazole-based dicarboxylic acid receptor derived from cholestane

  摘要：

  A new facial amphiphile cholestane-based receptor 1 containing a 2-imidazolylethylamino moiety at the 3 alpha and 7 alpha positions of cholestane was synthesized. Recognition selectivity of the new receptor 1 with various dicarboxylic acids was assessed by (1)H NMR titration. Maleic acid showed the highest binding constant among all the tested acids (K(a) = 9.36 x 10(4) M(-1)). (C) 2010 Elsevier Ltd. All rights reserved.
