Dimolybdenum complexes of bis(2-pyridyl)amine (Hdpa) ligand and its anion (dpa-); Transformation of chelating eta2-Hdpa to bridging eta2-dpa-

The reaction of trans-Mo2(O2CCR3)2X 2(PPh3)2 with 1 equiv. of Hdpa (Hdpa=bis(2-pyridyl)amine) in CH2Cl2 afforded the complex cis-Mo2(O2CCR3)2X 2(eta2-Hdpa) (R=H, X=Cl, 1; R=H, X=Br, 2; R=F, X=Cl, 3, R=F, X=Br, 4). Layering of a Mo2(O2CCF3)4 solution in CH2Cl2 with Hdpa in ether produced red and yellow crystals, which were characterized as Mo2(eta2-dpa)4 (5), and Mo2(O2CCF3)4(eta 1-HO2CCF3)2 ¡¤ 2Hdpa (6), respectively. Complex 5 can also be prepared by reaction of trans-Mo2(O2CCR3)2X 2(PPh3)2 with excess Hdpa. Their UV-Vis and IR spectra have been recorded and the structures of 4, 5 and 6 have been determined. The Hdpa ligand in 4 is coordinated to the metal centers via two terminal pyridine nitrogen atoms with a cis-N conformation. The dpa- ligands in 5 are bridged to the metal centers via one terminal nitrogen atom and the central nitrogen atom. The aligned-N conformation of the dpa- ligand is stabilized by both the intramolecular MoN and C-HN interactions. In 6, the CF3COOH ligands coordinate to the metal centers in the axial positions with eta1-bonding modes and the Hdpa molecules adapt cis-N conformations.

Design, synthesis, and biological activity of novel PPARgamma ligands based on rosiglitazone and 15d-PGJ2

To develop novel PPARgamma ligands, we synthesized thirteen 3-{4-(2-aminoethoxy)phenyl}propanoic acid derivatives, which are designed based on the structures of rosiglitazone and 15d-PGJ2. Among these compounds, compound 9 was found to be as potent as rosiglitazone in a binding assay and a preadipocyte differentiation test. Molecular modeling suggested that the nonyl group of 9 interacted with hydrophobic amino acid residues constructing the hydrophobic region of PPARgamma protein where the alkyl chain of 15d-PGJ2 is expected to be located.

Reactions of di-2-pyridylketone oxime in the presence of vanadium(III): Crystal structures of the coordination products

The reaction of di-2-pyridylketone oxime (dpko) in the presence of VCl3(THF)3 results in di-2-pyridylimine (dpi) with THF, amino-di-2-pyridyl-methyl ethyl ether (adpe) with ethanol and amino-di-2-pyridyl-methyl methyl ether (adpm) with methanol. The coordination complexes of these resulting ligands with vanadium, [VOCl2(dpi)(THF)] (1) (Pna21, a = 20.516(3), b = 6.479(3), c = 13.065(3) A, V = 1736(1) A3, Z = 4), [VOCl2(adpe)] (2) (P21/n, a = 8.496(2), b = 12.640(3), c = 15.036(2) A, beta = 95.84(2), V = 1606.4(5) A3, Z = 4), [VOCl2(adpm-NH2)] (3a) (P21/n, a = 9.47(2), b = 12.67(1), c = 12.48(1) A, beta = 95.0(1), V = 1490(3) A3, Z = 4) and [VOCl2(adpm-OMe)]¡¤MeOH (3b) (P21/n, a = 8.529(3), b = 15.293(2), c = 13.619(2) A, beta = 100.17(2), V = 1748.3(6) A3, Z = 4), have been characterized by X-ray crystal structure determination and EPR spectroscopy. All the compounds are monomers with a VOCl2 common unit. In contrast to the N-O bond cleavage and C-O bond formation to afford new tripodal ligands for 2 and 3, only the N-O bond cleavage reaction was observed for 1. The two isomers of 3 differ in the choice of coordination atom of the ligand, the amine nitrogen atom in 3a and the ether oxygen atom in 3b.

Silver(I) and copper(I) complexes with ferrocenyl ligands bearing imidazole or pyridyl substituents

The reactions between five ferrocenyl derivatives containing both a C{double bond, long}O and at least an imidazole or pyridine nitrogen atom and AgPF6, AgOTf, or [Cu(NCCH3)4]PF6 precursors were studied. The ligand {[bis(2-pyridyl)amino]carbonyl}ferrocene (L3), derived from (2-pyridyl)amine, favored tetrahedral coordination of Ag+ (with two ligands) and of Cu+ (with two acetonitrile ligands left from the precursor). In all the other ligands, both metal centers coordinated linearly to two ligands, preferring the imidazole or pyridinic nitrogen to other nitrogen atoms (amine) or oxygen donors. When the counter anions were triflate, the crystal structure showed a dimerization of the complex, with the ferrocenyl moieties occupying cis positions, by means of a weak Ag?Ag interaction. This was shown experimentally in the crystal structure of complex [Ag(L1)2]OTf (L1 = ferrocenyl imidazole) and in the presence of peaks corresponding to {Ag2(L2)3(OTf)}+ and {Ag2(L2)4(OTf)}+ in the mass spectra of [Ag(L2)2]OTf (L2 = ferrocenyl benzimidazole). In all complexes containing PF6, there was no evidence for dimerization. Indeed, in the crystal structure of [Ag(L2)2]PF6, the ferrocenyl moieties occupy trans positions and the metal centers are far from each other. DFT calculations showed that the energy of the cis and trans conformers is practically the same and the balance of crystal packing forces leads to dimerization when triflate is present.

A potential method to improve the: In vitro cytotoxicity of half-sandwich Os(ii) complexes against A2780 cells

The [Os(eta6-pcym)(dpa)(VP)]PF6 (1-VP) complex contains the histone deacetylase (HDAC) inhibitor valproate (2-propylpentanoate; VP) as a monodentate O-donor ligand and shows ca. 3-fold higher in vitro cytotoxicity against A2780 human ovarian carcinoma cells than its chlorido analogue [Os(eta6-pcym)(dpa)Cl]PF6 (1-Cl); pcym = 1-methyl-4-(propan-2-yl)benzene (p-cymene), dpa = 2,2?-dipyridylamine. The complex 1-VP showed promising selectivity towards the A2780 ovarian carcinoma cell line (IC50 = 20.9 muM) over normal human hepatocytes (IC50 > 200.0 muM). Moreover, the complex 1-VP was found to be inactive against MCF-7 (breast adenocarcinoma), PANC-1 (pancreatic adenocarcinoma) and HT-29 (colon carcinoma) up to a concentration of 100 muM. Detailed flow cytometry studies indicated that treatment of A2780 cells with complex 1-VP led to induction of apoptosis, production of reactive oxygen species (ROS) and superoxide (SO) anion radicals, as well as mitochondrial membrane potential depletion and cell cycle perturbations. The microscopic assessment (standard hematoxylin/eosin staining) revealed signs of morphological changes associated with the progression of apoptosis in A2780 cells treated with the IC50 concentration of the complex 1-VP. Consistent with the intracellular production of ROS and SO, the complex 1-VP induced hydroxyl radical formation, as proved by EPR spin trapping experiments. This case study suggests that replacement of the chlorido ligand of half-sandwich Os(ii) complexes by a releasable monodentate biologically active ligand (e.g., VP used in this study) is an effective strategy for the development of novel non-platinum cytotoxic agents.

Synthesis, magnetic, thermal and structural properties of Co(II), Ni(II) and Cu(II) complexes containing isophthalato ligands

A series of novel ternary Co(II), Ni(II) and Cu(II) complexes containing 2,2?-dipyridylamine (dipya), 2,2?-bipyridine (bipy), and 1,10-phenanthroline (phen), as aromatic diamine ligands, and dianion of isophthalic acid (ipht) have been prepared by ligand exchange reactions from diluted H2O/EtOH solutions. The complexes were characterized by elemental analysis, IR spectroscopy, magnetic susceptibility measurements and TG and DSC analysis. Three complexes, Cu(dipya)(ipht)¡¤H2O (1), Co(dipya)(ipht)¡¤2H2O (2) and Cu(ipht)(phen)¡¤2H 2O (5) are polymeric with bis-monodentate ipht, while the other two complexes M(bipy)(ipht)¡¤4H2O, MCo(II) (3) and Ni(II) (4), contain ipht as a counter ion. All Co(II) and Ni(II) complexes are (pseudo)octahedral, while Cu(II) complexes have square-pyramidal or distorted octahedral geometry. The variable temperature magnetic susceptibility measurements showed very weak antiferromagnetic behaviour for all complexes. Dehydration processes, decomposition mechanisms and thermal stability of 1-5 are assumed. One complex from the above series, [Ni(bipy)(H2O) 4](ipht) (4), and one additional complex, [Co(bipy)(ipht)] n (6), are obtained as single-crystals and their structures are determined from X-ray diffraction data. In both structures M(II) centers are in deformed octahedral environment and they are linked by hemi-ipht ligands (4) and two different bridging ipht ligands (6). Three-dimensional networks in 4 and 6 are governed by strong noncovalent interactions. The cations and ipht anions in 4 are connected by hydrogen bonds building double layers parallel to ab-plane that are further packed by pi-pi interactions. In 6 double chains extending along b-axis are strengthened by interchain pi-pi interactions constructing a three-dimensional framework.
