Complex [(IMes)(2)Pt(H)(ClBC(5)H(4)SiMe(3))] (IMes = 1,3-di(2,4,6-trimethylphenyl)imidazolin-2-ylidene) reacts with Lewis bases (L = pyridine, trimethylphosphine, acetonitrile, tert-butylisocyanide) to generate the kinetically favoured ion pairs [(IMes)(2)Pt(H)(L)][ClBC(5)H(4)SiMe(3)]. Over time, the formation of the thermodynamically favoured borabenzene-L adducts is observed with L = pyridine...

In the centrosymmetric polymeric title compound, {[CoHo(2)(C(14)H(8)N(2)O(5))(4)(H(2)O)(4)]·4H(2)O}(n), the Ho(III) ion is coordinated by one water mol-ecule and four 5-(pyridine-4-carboxamido)-isophthalate (L) ligands in a distorted square-anti-prismatic arrangement. The Co(II) ion, located on an inversion center, is coordinated by two pyridine N atoms, two carboxyl-ate O atoms and two water m...

In this study, we used a 6-methyl-2,3-pyridine dicarboxylate ligand to develop the frameworks. Two novel compounds, [Zn2(L)2(H2O)4] (1) and [Cd(L)(H2O)] (2) (where L = 6-methyl-pyridine-2,3-dicarboxylate) were produced. The compounds characterized by elemental analysis, powder X-ray diffraction, Fourier-transform infrared spectroscopy single crystal crystallography. We successfully tuned framew...

Transport of seven different amino acids into brain slices increased as donor rats aged from 1 to 6 days. Uptakes of 2-aminoisobutyric acid, 2-(methyl-amino)isobutyric acid, and L-alanine then decreased by day 14, while uptakes of other amino acids continued to increase or remained fairly constant. Neutral alpha-amino acid transport systems were characterized by measuring inhibition of uptakes ...

Cu(II) complexes of three tridentate ligands, L(1), L(2) and L(3), [L(1), N-((1H-imidazole-2-yl)methyl)-2-(pyridine-2-yl)ethanamine; L(2), N-((1-methyl-1H-imidazole-2-yl)methyl)-2-(pyridine-2-yl)ethanamine; L(3), 2-(pyridine-2-yl)-N-((pyridine-2-yl)methyl)ethanamine] respectively, were synthesized and characterized. The single crystal X-ray structure of complex 1 reveals the pseudo octahedral c...

The effects of capsaicin and mucosal acidification on gastric HCO3(-) secretion were compared in wild-type and prostacyclin (PGI2) IP receptor or prostaglandin E receptor EP1 or EP3 knockout C57BL/6 mice as well as rats. Under urethane anesthesia, the stomach was mounted on an ex vivo chamber, perfused with saline, and the secretion of HCO3(-) was measured at pH 7.0 using the pH-stat method. Ca...

Two isostructural NiII compounds, bis-{N-[1-(pyridin-2-yl-κN)eth-ylidene]pyridine-4-carbohydrazonato-κ2N',O}nickel(II)-2,5-di-chloro-terephthalic acid (1/1), [Ni(C13H11N4O)2](C8H4Cl2O4), and bis-{N-[1-(pyridin-2-yl-κN)eth-ylidene]pyridine-4-carbohydrazonato-κ2N',O}nickel(II)-2,5-di-bromo-terephthalic acid (1/1), [Ni(C13H11N4O)2](C8H4Br2O4), were synthesized and their crystal structures determin...

Four copper(II) complexes and one copper(I) complex with pyridine-containing pyridylalkylamide ligands N-(pyridin-2-ylmethyl)pyrazine-2-carboxamide (HL) and N-(2-(pyridin-2-yl)ethyl)pyrazine2-carboxamide (HL) were synthesized and characterized. The X-ray crystal structures of [Cu2(L )2(4,4ʹ-bipy)(OTf )2] (1, OTf = trifluoromethanesulfonate, 4,4ʹ-bipy = 4,4ʹ-bipyridine) and [Cu(L)(py)2]OTf·H2O (...
