Tissue inhibitors of metalloproteinases (TIMPs) regulate the activity of matrix metalloproteinases (MMPs) and enzymes from the a disintegrin and metalloproteinase domain with thrombospondin motifs family in osteoarthritis (OA). Elevated osteopontin (OPN) levels in plasma, synovial fluid and articular cartilage are associated with progressive OA joint(More)
Our previous work revealed transforming growth factor beta1 (TGFβ1) gene polymorphisms are associated with susceptibility to hepatocellular carcinoma and liver cirrhosis. However, no further study of functional substitution in hepatic cells has yet been reported. This study was designed to uncover the functional mechanisms of TGFβ1 gene polymorphisms in the(More)
In the title compound, C(10)H(12)N(2)O(3)·H(2)O, the Schiff base mol-ecule is approximately planar [within 0.189 (1) Å]. The inter-planar angle between the benzene and acetohydrazide planes is 8.50 (10)°. In the crystal, mol-ecules are linked into a three-dimensional network by strong and weak O-H⋯O and strong N-H⋯O hydrogen bonds. The hydr-oxy H atom(More)
The title compound, (C(4)H(7)N(4)O)(2)[Bi(2)Cl(9)(C(4)H(7)N(4)O)]·H(2)O, was prepared by the reaction of bis-muth trichloride and 5-amino-1H-imidazole-4-carboxamide in a dilute HCl medium. The asymmetric unit contains two 5-amino-4-amino-carbonyl-1H-imidazol-3-ium cations, one edge-shared non-centrosymmetric biocta-hedral [Bi(2)C1(9)(C(4)H(7)N(4)O)](2-)(More)
In the title mol-ecule, C(10)H(12)N(2)O(2), the acetohydrazide group is planar within 0.012 (1) Å and forms a dihedral angle of 5.25 (8)° with the benzene ring. The meth-oxy group is coplanar with the attached benzene ring [C-O-C-C = 0.1 (2)°]. The mol-ecule adopts a trans configuration with respect to the C=N double bond. In the crystal, mol-ecules are(More)
The mol-ecule of the title compound, C(10)H(12)N(2)O(4), adopts a trans configuration with respect to the C=N bond. The dihedral angle between the benzene ring and the methyl hydrazinecarboxyl-ate plane is 3.01 (6)°. An intra-molecular O-H⋯N hydrogen bond is observed. In the crystal, mol-ecules are linked into a two-dimensional network parallel to (10) by(More)
The title compound, C(10)H(12)N(2)O(4), adopts a trans configuration with respect to the C=N bond. The hydrazinecarboxyl-ate group is twisted from the benzene ring by 6.62 (5)° and an intramolecular O-H⋯O hydrogen bond occurs. In the crystal structure, mol-ecules are linked into a two-dimensional network parallel to (100) by O-H⋯O, N-H⋯O and C-H⋯O hydrogen(More)
The title mol-ecule, C(12)H(16)N(2)O(5), adopts a trans configuration with respect to the C=N bond. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains in [001], and weak inter-molecular C-H⋯O inter-actions further link the chains into corrugated layers parallel to the bc plane.
The title compound, C(10)H(12)N(2)O(4), adopts a trans configuration with respect to the C=N double bond. The non-H atoms of the mol-ecule are essentially coplanar, with a maximum deviation of 0.015 (2) Å. An intra-molecular O-H⋯N inter-action is observed. In the crystal structure, the mol-ecules are linked into a two-dimensional network parallel to the ac(More)
