Guaiacol is a phenolic natural product first isolated from Guaiac resin and the oxidation of lignin. Guaiacol is readily oxidized by the heme iron of peroxidases including the peroxidase of cyclooxygenase (COX) enzymes. It therefore serves as a reducing co-

(Z)-2-(3-hydroxy-4-methoxybenzylidene)-1-azabicyclo[2.2.2]octan-3-one
Crystals of the title compound, C(15)H(17)NO(3), were obtained from a condensation reaction of 3-hydroxy-4-methoxybenzaldehyde with 1-azabicyclo[2.2.2]octan-3-one and subsequent crystallization of the product from methanol. The title compound, containing a double bond that connects the azabicyclic ring system to the 3-hydroxy-4-methoxybenzylidene group, was obtained with Z geometry.
Rate coefficients for the gas-phase reaction of hydroxyl radicals with 2-methoxyphenol (guaiacol) and related compounds
2-Methoxyphenol (guaiacol) and its derivatives are potential marker compounds for wood smoke emissions in the atmosphere. To investigate the atmospheric reactivity of this type of compounds, rate coefficients for their reactions with hydroxyl (OH) radicals have been determined at 294 ㊣ 2 K and 1 atm using the relative rate method with gas chromatography for chemical analysis. The rate coefficients (in units of cm? molecule?? s??) are: 2-methoxyphenol, (7.53 ㊣ 0.41) ℅ 10???; 3-methoxyphenol, (9.80 ㊣ 0.46) ℅ 10???; 4-methoxyphenol, (9.50 ㊣ 0.55) ℅ 10???; 2-methoxy-4-methylphenol, (9.45 ㊣ 0.59) ℅ 10???; and methoxybenzene, (2.20 ㊣ 0.15) ℅ 10???. The estimated atmospheric lifetime for 2-methoxyphenol is ~2 h, indicating that it is too reactive to be used as a tracer for wood smoke emissions. The reactivity of the methoxyphenols is compared with other substituted aromatics and interpreted in relation to the type, number, and positions of the different substituents on the aromatic ring. The atmospheric implications of the reactions are also discussed.
Syntheses, crystal structures and biological evaluation of two new Cu(II) and Co(II) complexes based on (E)-2-(((4H-1,2,4-triazol-4-yl)imino)methyl)-6-methoxyphenol
Two transition metal complexes of [M(TMP)2(H2O)2] (TMP-Cu, M = Cu; TMP-Co, M = Co) with (E)-2-(((4H-1,2,4-triazol-4-yl)imino)methyl)-6-methoxyphenol (H-TMP) were first synthesized and characterized by infrared analysis, elemental analysis and single crystal X-ray diffraction analysis. Notably, MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay showed that TMP-Cu displayed relatively high cytotoxic activity against Hep-G2 cancer cells, and high selectivity between human hepatocellular carcinoma cells and normal HL-7702 cells, in comparison to TMP-Co and cisplatin. Further studies showed that TMP-Cu and TMP-Co caused cell cycle arrest at S phase through regulation of S phase related protein expressions and induced Hep-G2 cell apoptosis via the mitochondrial pathway.
(Z)-2-(3-methoxybenzylidene)-1-azabicyclo[2.2.2]octan-3-one
The crystal structure of the title compound, C(15)H(17)NO(2), contains two nearly identical but crystallographically independent molecules, each with a double bond connecting an azabicyclic ring system to a 3-methoxybenzylidene moiety. The space group is triclinic P-1. The benzene ring is twisted by 18.44 (5) and 22.35 (4) degrees with respect to the plane of the double bond connected to the azabicyclic ring system for the two molecules. In addition to C-H...pi interactions, molecules are held together in the solid state by van der Waals interactions.
Spectroscopic study and structure of (E)-2-[(2-chlorobenzylimino)methyl]methoxyphenol
(E)-2-[(2-chlorobenzylimino)methyl]methoxyphenol has been synthesized from the reaction of 2-hydroxy-3-methoxy-1-benzaldehyde(o-vanillin) with 2-chlorobenzylamine. The title compound has been characterized by using elemental analysis, FT-IR, (1)H NMR, (13)C NMR and UV-vis spectroscopic techniques. The crystal structure of the title compound has also been examined cyrstallographically. It crystallizes in the orthorhombic space group Pbca with unit cell parameters: a = 7.208(1) A, b = 13.726(2) A, c = 27.858(4) A, V = 2756.0(1) A(3), D(c) = 1.18 g cm(-3) and Z = 8. The crystal structure was solved by direct methods and refined by full-matrix least squares to a find R = 0.046 for 2773 observed reflections.
