  Spectroscopic and cytotoxic characteristics of (p-cymene)Ru(II) complexes with bidentate coumarins and density functional theory comparison with selected Pd(II) complexes

  摘要：

  This paper presents the synthesis of two new (p-cymene)-ruthenium(II) complexes 3a,b with the bidentate coumarin ligands 2a,b. Both complexes were characterized by FTIR spectroscopy, H-1 NMR, C-13 NMR, MS, elemental analysis and DFT calculations. The X-ray structure of complex 3a was also solved. The cytotoxic properties of both complexes were examined on human leukemia NALM-6 and HL-60 cells and melanoma WM-115 cells. The complexes possess higher cytotoxic activity than the ligands, but distinctive result is for complex 3b, which exhibited higher cytotoxic effect on WM-115 cells (IC50 = 60.2 +/- 7.8 mu M) in comparison to carboplatin (IC50 = 422.2 +/- 50.2 mu M). The results of DFT calculations performed at the BP86-D3/QZ4P level for Ru(II) complexes and Pd(II) complexes with the same ligands indicate that Pd(II) complexes are more lipophilic. Moreover the RP-TLC-Based Lipophilicity assessment was also performed. (C) 2016 Elsevier B.V. All rights reserved.

  Inhibitors of muscle myosin ATPases are needed to treat conditions that could be improved by promoting muscle relaxation. The lead compound for this study ((3-(N-butylethanimidoyl)ethyl)-4-hydroxy-2H-chromen-2-one; BHC) was previously discovered to inhibit skeletal myosin II. BHC and 34 analogues were synthesized to explore structure–activity relationships. The properties of analogues, including solubility

  Abstract A one-pot route was developed for efficient synthesis of novel 2-substituted quinolin-4-carboxamides via a four-component sequential reaction between isatins, ammonium acetate, triethyl orthoacetate, and 4-hydroxycoumarin or 4-hydroxy-6-methyl-2H-pyran-2-one. This protocol is an extension of Pfitzinger’s quinoline synthesis and involves an unprecedented in situ iminoacetylation of 2H-pyrone
