  Triazole-curcuminoids: A new class of derivatives for ‘tuning’ curcumin bioactivities?

  摘要：

  Curcumin is a unique blend of pharmacophores responsible for the pleiotropy of this natural pigment. In the present study we have replaced the 1,3-dicarbonyl moiety with a 1,2,3-triazole ring to furnish a new class of triazole-curcuminoids as a possible strategy to generate new compounds with different potency and selectivity compared to curcumin. We obtained a proof-of-principle library of 28 compounds tested for their cytotoxicity (SY-SY5Y and HeLa cells) and for their ability to inhibit NF-kappa B. Furthermore, we also generated 1,3-dicarbonyl curcuminoids of selected click compounds. Triazole-curcuminoids lost their ability to be Michael's acceptors, yet maintained some of the features of the parent compounds and disclosed new ones. In particular, we found that some compounds were able to inhibit NF-kappa B without showing cytotoxicity, while others, unlike curcumin, activated NF-kappa B signalling. This validates the hypothesis that click libraries can be used to investigate the biological activities of curcumin as well as generate analogs with selected features. (C) 2015 Elsevier Ltd.

  The vinylideneruthenium(II) complexes bearing bulky and basic tertiary phosphine ligands, RuCl2(CCHPh)L2 (L = PPri3, PCy3), serve as good catalyst precursors for (Z)-selective cross-dimerization between arylacetylenes and silylacetylenes in the presence of N-methylpyrrolidine.

  and E-selectivity (25–99% yield, 17 → >99:1 E:Z, 27 examples). Importantly, “cross-dimerizations” of terminal alkynes that are typically rare are also possible and occur with unusually high levels of stereoselection. In addition, macrocyclic hydroalkynylations are reported in good to high yields, affording macrocyclic enyne motifs, which are found in numerous bioactive natural products

  A new fulvene synthesis results from the palladium-catalyzed [2+2+2] annulation of 1 mol of a β-substituted vinyl iodide and 2 mol of a monosubstituted acetylene. This variant of the Heck reaction tolerates a wide range of substrate substituents with the best results obtained by using the catalyst, Pd(CH 3 CN) 2 Cl 2 . Addition of Cu I I to the reaction affords high yields of 1,3-enyne and no fulvene

  日期：——

  The new iridium(I)-guanidinate complex served as an efficient catalyst for phosphine-dependent selective cross-dimerization between silylacetylene and terminal alkyl- or arylacetylene. Especially, in case of cross-dimerization between silylacetylene and alkylacetylene, E/Z selectivity of resulting enynes could be controlled by changing phosphine.
