AB  - Hybrid compounds that combine the 1,3,4-thiadiazole-containing catechol moiety with a chalcone motif were synthesized and examined for their antioxidant activity, cytotoxicity, and DNA-binding activity. A series of thirteen compounds showed strong antioxidant and cytotoxic effects on human acute promyelocytic leukemia HL-60 cells. Several compounds exerted good cytotoxic activities on cervical adenocarcinoma HeLa cells. The treatment of HeLa cells with IC50 and double IC50 concentrations of the compounds 5a, 5c, 5f, and 5m induced a statistically significant increase in the percentage of cells within a subG1 cell cycle phase. The examined compounds caused G2/M cell cycle arrest in HeLa cells. Each of these compounds triggered apoptosis in HeLa cells through activation of caspase-3, the main effector caspase, caspase-8, which is involved in the extrinsic apoptotic pathway, and caspase-9, which is involved in the intrinsic apoptotic pathway. All of the examined compounds decreased the expression levels of MMP2 in HeLa cells and levels of protumorigenic miR-133b. Compounds 5a and 5m lowered the expression level of oncogenic miR-21 in HeLa cells. In addition, compounds 5a, 5f, and 5m decreased the expression levels of oncogenic miR-155 while the treatment of HeLa cells with compounds 5a, 5c, and 5f increased expression of tumor-suppressive miR-206. Observed effects of these compounds on expression levels of four examined miRNAs suggest their prominent cancer-suppressive activity. An investigation by absorption and fluorescence spectroscopy showed more efficient calf thymus DNA binding activity of the compound 5m in comparison to other tested compounds. Results of a pUC19 plasmid cleavage study and comet assay showed DNA damaging activities of compounds 5a and 5c.

AB  - The interactions of nine amino acid derivatives of tert-butylquinone with biomacromolecules were studied. Sodium dodecyl sulphate (SDS) gel electrophoresis and mass spectrometry confirmed the absence of modifications of lysozyme by any of the synthesized compounds. Spectrophotometric studies demonstrated hyperchromism, i.e., the existence of interactions between the quinones and calf thymus DNA (CT-DNA). Determination of the binding constants by absorption titration indicated weak interactions between the quinone derivatives and CT-DNA. The quenching of fluorescence of the intercalator ethidium bromide (EB) from the EB-CT-DNA system and of the minor groove binder Hoechst 33258 (H) from the H-CT-DNA system by the synthesized derivatives indicated interactions of the compounds and CT-DNA. Circular dichroism (CD) spectra demonstrated a non-intercalative binding mode of the quinone derivatives to CT-DNA. Molecular docking results confirmed binding to the minor groove. The electrophoretic pattern showed no cleavage of the pUC19 plasmid in the presence of any of the synthesized compounds. The ability of the derivatives to scavenge radicals was confirmed by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) test. All the presented results suggest that the DNA minor groove binding is the principal mechanism of action of the examined amino acid derivatives.

AB  - A new Zn(II)-based potential chemotherapeutic agent was synthesized from the ligand 2-quinolinecarboxaldehyde selenosemicarbazone (Hqasesc). Single crystal X-ray diffraction analysis showed that the Zn(II) complex consists of a cation [Zn(Hqasesc)(2)](2+), two perchlorate anions and one ethanol solvent molecule. The interaction of calf thymus (CT) DNA and human serum albumin (HSA) with the Zn(II) complex was explored using absorption and emission spectral methods, and also has been supported by molecular docking studies. The complex has more affinity to minor DNA groove than major, with no significant intercalation. The HSA interaction studies of the complex revealed the quenching of the intrinsic fluorescence of the HSA through a static quenching mechanism. The antitumor activity of the ligand and the complex against pancreatic adenocarcinoma cell line (AsPC-1) and acute monocytic leukemia (THP-1) cells was evaluated. Both compounds are strong concentration-dependent apoptosis inducers in THP-1 cells. While Hqasesc in AsPC-1 cells induces apoptosis only at the highest concentration, treatment with the Zn complex shows a concentration-dependent apoptotic response, where the treated cells are arrested in the G1-to-S phase accompanied with extensive activation of caspase-8 and -9. These results indicate that the ligand and Zn(II) complex display cell phenotype specific activity.

AB  - Complexes of Pd(II) and Fe(III) with the condensation derivative of 2-(diphenylphosphino)benzaldehyde and ethyl carbazate were synthesized, characterized, and their antimicrobial activity was evaluated. The structures of the Pd(II) and Fe(III) complexes in solid state were determined by IR, elemental analysis and X-ray analysis. The structure of Pd(II) complex in solution was determined by NMR spectroscopy. Results of magnetic measurements for Fe(III) complex were reported. In both complexes the ligand is coordinated as tridentate via the phosphorus, the imine nitrogen and the carbonyl oxygen atoms. Results of antimicrobial activity investigation indicate that the activity of the ligand is enhanced upon complexation, and that the MIC values of the iron complex to some bacterial strains are not much higher than those of cefotaxime.

AB  - A new malonic dihydrazide-based ligand, N,N(2)-bis[(1E)-1-(2-quinolyl)methylene]propanedihydrazide (H(2)L3), has been prepared and characterized by elemental analysis, IR, C-13 NMR, and H-1 NMR spectroscopies. In the reaction of H(2)L3 with Ni(II) a binuclear complex has been obtained. The structure of the complex was established by X-ray analysis. Each Ni(II) is coordinated with two NNO donor sets from two ligand molecules in dianionic form (L3(2-)) forming an octahedral geometry. Multiple intramolecular C-H center dot center dot center dot pi (chelate ring) interactions support the molecular geometry of the [Ni-2(L3)(2)] complex. The structure of [Ni-2(L3)(2)] is compared with those of analogous Ni(II) complexes with pyridine dihydrazone type ligands. Magnetic behavior of the dinuclear complex was studied in temperature range of 2-300 K.

abstract = "A new malonic dihydrazide-based ligand, N,N(2)-bis[(1E)-1-(2-quinolyl)methylene]propanedihydrazide (H(2)L3), has been prepared and characterized by elemental analysis, IR, C-13 NMR, and H-1 NMR spectroscopies. In the reaction of H(2)L3 with Ni(II) a binuclear complex has been obtained. The structure of the complex was established by X-ray analysis. Each Ni(II) is coordinated with two NNO donor sets from two ligand molecules in dianionic form (L3(2-)) forming an octahedral geometry. Multiple intramolecular C-H center dot center dot center dot pi (chelate ring) interactions support the molecular geometry of the [Ni-2(L3)(2)] complex. The structure of [Ni-2(L3)(2)] is compared with those of analogous Ni(II) complexes with pyridine dihydrazone type ligands. Magnetic behavior of the dinuclear complex was studied in temperature range of 2-300 K.",

AB  - Three novel copper(II) complexes as condensation derivatives of 2-pyridinecarboxaldehyde, 2-acetylpyridine or 2-quinolinecarboxaldehyde with ethyl hydrazinoacetate hydrochloride were synthesized. X-ray crystal structures of all three complexes were determined. Crystallographic data indicate a common basis of the structures with some major differences. Both pyridine derivatives form complexes of the type [CuCl(2)L] with distorted square-planar geometry around copper(II), but show a decisive difference in the side chain orientation. The quinoline derivative forms a dimeric complex of type [Cu(2)Cl(4)L(2)] with distorted trigonal bipyramidal geometry around copper(II), but a rather short Cu center dot center dot center dot Cu contact, which is reflected in its magnetic properties. All three complexes showed antibacterial activity. (c) 2008 Elsevier B.V. All rights reserved.
