Verification of microbial ethanol formation in humans by examination of postmortem indoleamine metabolites.
(2004)
Toxicological examination of fatal aviation accident victims routinely includes analysis of ethanol levels. Two distinct questions immediately arise when considering such analyses. The first is, can we stop ethanol production ...
Investigations into the neurodegenerative mode of action of dihydroxytetrahydroquinoline derivatives.
(1997)
Preliminary testing of a dihydroxyguinoline derivative, 3-amino-6,7-dihydroxy-1,2,3,4-tetrahydroquinoline (6,7-ADTQ), showed substantial serotonergic depletion in mouse whole brain, but with only moderate selectivity. This ...
Structural, protonation, and complexation studies of ionophores A23187, 4-ClA23187, and 23,24-Br(2)A23187.
(2006)
A23187 is a carboxylic acid polyether ionophore best known for transporting calcium through membranes. However, it has been shown that it transports Zn 2+, Cd2+, and Mn2+ more selectively than Ca2+. Derivatives of A23187 ...
The effect of substitution at the 9 position of the electrochemical oxidation of xanthine.
(1980)
The electrochemical oxidation of xanthosine was shown to be nearly identical to that of 9-methylxanthine. The major difference being the ribose substituent in the observed products.

Studies of the complexation reactions of polyether ionophore antibiotics nigericin and salinomycin with lead(II), zinc, calcium, magnesium, sodium and potassium cations.
(2005)
CD studies in 80% methanol-water indicate that Pb2+ forms 1:1 complexes almost quantitatively with monensin, nigericin, narasin, maduramicin, and salinomycin. UV-Vis titrations in 80% methanol-water showed the same result ...
Single-molecule spectroscopic investigation of the influence that charge-charge interactions, solvation, and confinement have on guest molecule rotational mobility and photostability within silica sol-gel host matrices.
(2006)
To investigate physical immobilization further, guest behavior was monitored within the more highly branched silica nanoparticle matrix, when covalently bonded to silica nanoparticles, and within pores templated by gold ...
Studies of the complexation reactions of polyether ionophore antibiotics monensin A and lasalocid A with lead(II), zinc, calcium and sodium cations.
(2000)
Lead-ionophore complexes of the form PbLX and PbL2 (L = monensin A or lasalocid A; X- = anion) were isolated and characterized by elemental analysis (X = Cl--) and ESI-MS (X = Cl --, NO3, CH3COO--). Changes in the UV-Vis ...
Part I. Kinetic studies of the complexation reactions of nickel(II) with hydroxamic acids in aqueous medium. Part II. Kinetic studies of the formation and dissociation reactions of ionomycin and 2,6-dimethylheptane-3,5-dione with nickel(II) and magnesium(II) in 80 percent methanol-water medium.
(1997)
The second part of the study involved the reactions of nickel(II) and magnesium(II), with the ionophore ionomycin and the model compound 2,6-dimethyl-3,5-heptanedione (DMHD). A detailed analysis of the kinetic data for ...
