Effects of steric/basic properties of Lewis bases on the degree of aggregation of zinc(II) pivalate complexes

A triangular [Zn3(mu3-OH)(OC(O)tBu) (mu2-kappa1O:kappa1O?-O 2CtBu)4(3,5-lutidine)3] (1), a paddlewheel based dinuclear [Zn(mu2-kappa1O: kappa1O?-O2CtBu)2L] 2 [L = 2,4-lutidine (2), 3,4-lutidine (3), and 2,3-lutidine (4)] and an hourglass based linear trinuclear [Zn3(mu2- kappa1O:kappa1O?-O2C tBu)6(pyridine)2] (5) complexes were synthesized to understand the role of subtle steric/basic properties of Lewis bases on the degree of aggregation of the products. The mononuclear Zn(OC(O)tBu)2¡¤2H2O was also prepared in order to probe the origin of the mu3-OH moiety in complex 1. Complexes 1-5 and Zn(OC(O)tBu)2¡¤2H2O were characterized by microanalytical, IR, TGA/DTA, solution (1H and 13C) NMR, solid-state cross-polarization magic angle spinning (CP-MAS) 13C NMR, mass spectral data and single crystal X-ray diffraction data. Complex 1 represents the first example of a discrete trinuclear zinc(II) carboxylate complex that contains a [Zn3(mu 3-OH)]5+ core with zinc atoms in three distinct geometries namely a distorted tetrahedral, trigonal bipyramidal, and octahedral. A plausible mechanism for the formation of complexes 1-5 was explained with the aid of point zero charge (pzc) model.

Efficient production of red Monascus pigments with single non-natural amine residue by in situ chemical modification

Filamentous fungi Monascus sp. has been utilized for fermentative production of food colorant (Red Yeast Rice) for more than 1000?years in China. The main colorant components of Red Yeast Rice are mixture of red Monascus pigments (RMPs) with various primary amine residues. In the present work, the non-natural primary amine p-aminobenzamide, exhibiting as non-involved in nitrogen microbial metabolism, nontoxicity to microbial cells, and chemical reactivity with orange Monascus pigments (OMPs), was screened. Based on the screened result, RMPs with the single p-aminobenzamide residue were produced by cell suspension culture in a nonionic surfactant micelle aqueous solution via in situ chemical modification of OMPs. Furthermore, in situ chemical modification of OMPs also provided a strategy for maintaining a relatively low OMP concentration and then efficient accumulation of high concentration of RMPs (3.3?g/l).

Synthesis and characterization of the adducts of bis(O-amyldithiocarbonato) nickel(II) with nitrogen donors and X-ray structure of bis(O- amyldithiocarbonato)bis (3,5-dimethylpyridine)nickel(II)

A series of complexes with general formula M(Xan)2L2 (M = Ni(II), Xan = O-amyldithiocarbonato, L = 3-methylpyridine, 2,4-; 3,4-; 3,5-dimethylpyridines and 2,4,6-trimethylpyridine) have been synthesized and characterized by elemental analysis and various physico-chemical techniques such as magnetic susceptibility measurements, conductivity measurements, UV-Visible, Infrared spectral data. On the basis of electronic spectra and magnetic susceptibility measurements, an octahedral geometry has been proposed for all the complexes. IRspectral data shows that the substituted pyridines in all these complexes coordinate to the metal ion through nitrogen atoms occupying fifth and sixth axial positions where as O-alkyldithiocarbonate act as monoanion bidentate ligand and occupy the planar positions of octahedral structures. The X-ray diffraction analysis of one of the adducts bis(O-amyldithiocarbonato) bis(3,5-dimethylpyridine) nickel(II) is also investigated. The complex crystallizes in the monoclinic space group P21/c with unit cell parameters a = 9.167(2) A, b = 18.255(4) A, c = 9.299(2) A and beta = 103.47(2). The dihedral angle between dithio-groups and the pyridine ring is 88.9(1). The crystal structure of the molecule is stabilized by pi-pi interactions. Springer Science+Business Media New York 2012.

Potent and selective aggrecanase inhibitors containing cyclic P1 substituents

Anti-succinate hydroxamates with cyclic P1 motifs were synthesized as aggrecanase inhibitors. The N-methanesulfonyl piperidine 23 and the N-trifluoroacetyl azetidine 26 were the most potent aggrecanase inhibitors both having an IC50=3 nM while maintaining >100-fold selectivity over MMP-1, -2, and -9. The cyclic moieties were also capable of altering in vivo metabolism, hence delivering low clearance compounds in both rat and dog studies as shown for compound 14.
