  Two new half‐sandwich Ru (II)(p‐cymene) complexes (1 and 2) containing dopamine‐based (N, O) Schiff base ligands (L1H and L2H) were synthesized and characterized by FT‐IR, UV–Visible and 1H & 13C NMR spectral techniques, and elemental analyses. The spectroscopic and analytical data revealed monobasic bidentate coordination of the ligands with Ru ion. The molecular structures of L1H, L2H and 2 were

  Some of the N-benzyltetrahydroisoquinoline derivatives synthesized in our previous works [ 1, 2] exhibit a pronounced choleretic activity. However, we failed to find any data on the effect of these compounds on the process of bile secretion and the antitoxic function of liver in the available literature. In this connection it was of interest to continue our investigations on the synthesis of N-ben

  在我们之前的工作中合成的一些 N-苄基四氢异喹啉衍生物 [1, 2] 表现出明显的利胆活性。然而，我们未能在现有文献中找到有关这些化合物对胆汁分泌过程和肝脏抗毒功能影响的任何数据。在这方面，我们有兴趣继续研究 N-苄基四氢异喹啉的合成并研究它们的利胆活性。新的衍生物 (IX) 是使用高戊烯胺或高胡椒胺和取代的苯甲醛 [3] 合成的，这些苯甲醛是通过相应的苯甲醛 [4, 5] 的卤化或氮化获得的。

  New Schiff base ligands were synthesized by condensation of 2-(3,4-dimethoxyphenyl)ethanamine with 2-hydroxy benzaldehyde ((LH)-H-1) and 2'-hydroxy acetophenone ((LH)-H-2) respectively. Reaction of (LH)-H-1 or (LH)-H-2 with Na2PdCl4 or NiCl2 center dot 6H(2)O in 2:1 ratio obtained four new coordination complexes [M(L1-2)(2)] (where M = Pd(II); 1 and 2 and M = Ni(II); 3 and 4). Both the ligands and four complexes were characterised by elemental analysis, FT-IR and UV-Vis, spectroscopy. (LH)-H-1, (LH)-H-2, 1 and 2 were also characterised by H-1 and C-13H-1} NMR spectroscopy. The molecular structures of 1 and 3 were determined by single crystal X-ray diffraction. The spectroscopic and crystal structure data showed that the ligands coordinated to M (II) ion in a bidentate monoanionic (O , N) fashion. The Pd-O and Pd-N bond lengths in 1 are 1.984(11) and 2.020(12) angstrom in 3 the Ni-O and Ni-N bond lengths are 1.8222(13) and 1.9262(15) angstrom respectively. The C=N bond length in 3 found 1.290(2) angstrom which was shorter than 1.310(19) angstrom in 1. The bond angles provided square planar geometry around Pd(II) and Ni(II) in both 1 and 3. There exists C-H center dot center dot center dot O type (2.50-2.52 angstrom) intermolecular hydrogen bonding in both 1 and 3 resulting in supramolecular structures. The antimicrobial activity of new Schiff base ligands and their Pd(II) and Ni(II) complexes against pathogenic microbial strains by agar well diffusion method was conducted. All the ligands and complexes showed significant antibacterial and antifungal activities. The bacterial and fungi growth inhibition activity of ligands has been increased on complexation as well as among complexes palladium complexes were found better antibacterial and antifungal agents than the nickel complexes of corresponding ligands. Ligand (LH)-H-1 and the complex 2 showed highest antibacterial activity against Pseudomonas desmolyticum and highest antifungal activity against Candida albicans. (C) 2015 Elsevier B.V.
