	abstract = {Four mixed O,S binding ligand precursors derived from maltol (3-hydroxy-2-methyl-4-pyrone) have been chelated to gallium(III), indium(III), and lanthanide(III) ions to yield a series of metal complexes. The four ligand precursors include two pyranthiones, 3-hydroxy-2-methyl-4-pyranthione, commonly known as thiomaltol (Htma), and 2-ethyl-3-hydroxy-4-pyranthione, commonly known as ethylthiornaltol (Hetma), and two pyridinethiones, 3-hydroxy-2-methyl-4(H)-pyridinethione (Hmppt) and 3-hydroxy-1,2-dimethyl-4-pyridinethione (Hdppt). Dimeric forms of the pyridinethiones, Hmppt dimer and Hdppt dimer, were also isolated and characterized. Complete characterization of the monomeric organic compounds is reported including acidity constants and crystal structures of Htma, Hetma, and Hdppt dimer. Reacting the four monomeric ligand precursors with Ga3+ and In3+ ions yielded new tris(bidentate ligand) complexes. X-ray-quality crystals of the fac isomer of Ga(tma)(3) were also obtained. New complexes with a range of anthanicles (Ln(3+)) were also synthesized with the two pyranthiones, Htma and Hetma. The synthesis reactions yielded complexes of the type LnL(3)center dot xH(2)O and LnL(2)(OH)center dot xH(2)O, as indicated by elemental analysis and spectroscopic evidence such as mass spectral data and IR and NMR spectra.},

A new ligand, bis[4-acetyl-3-hydroxyphenyl]-1,6-heptadiene-3,5-dione (diacetylbisdemethoxycurcumin, DABC) was similarly characterized; an X-ray structure analysis was performed. Vanadyl complexes tested in an acute i.p. testing protocol in STZ-diabetic rats showed a lack of insulin enhancing potential. Vanadyl complexes were, however, more cytotoxic than were the ligands alone in standard MTT (3-[4,5-dimethylthiazole-2-yl]ate, -2.5-diphenyl-tetrazolium bromide) cytotoxicity testing, using mouse lymphoma cells. With the exception of DABC, that was not different from VO(DABC)(2), the complexes were not significantly different from one another, with IC50 values in the 5-10 mu M range. Gallium and indium curcumin complexes had IC50 values in the same 5-10 mu M range; whereas Ga(DAC)(3) and In(DAC)(3) (where DAC = diacetylcurcumin) were much less cytotoxiC (IC50 = 20-30 mu M). Antioxidant capacity was decreased in VO(DAC)(2), Ga(DAC)(3), and In(DAC)(3),, compared to vanadyl, gallium and indium curcumin, corroborating the importance of curcumin{\textquoteright}s free phenolic OH groups for scavenging oxidants, and correlated with reduced cytotoxic potential.

	abstract = {Addition of LiAlH4 to the monomeric chlorides syn-MCl[P2N2] (M = Al (1), Ga (2), In (3)) results in the formation of the aluminum hydride syn-AlH[P2N2] (4). The solution H-1- and P-31{H-1}-NMR spectra are consistent with a C-20 symmetric species in solution. The X-ray crystal structure shows the hydride to be monomeric, and free from interaction with either salt (LiCl) or external base (Et2O). The coordination of both phosphines of the macrocycle to the metal center is found in the solid state. Solution molecular weight measurements are consistent with a monomeric structure. The gallium hydride syn-GaH[P2N2] (5) is synthesized by the addition of LiGaH4 to syn-MCl[P2N2] (M = Ga (2), In (3)). This species is unstable and could only be characterized in solution. Reduction of syn-MCl[P2N2] (M = Ga (2), In (3)) with KC8 yields the reduced, dimeric species {syn-M[P2N2]}(2) (M = Ga (6), In (7)). The solution H-1- and P-31{H-1}-NMR spectra are consistent with C-2v symmetric species in solution. The X-ray crystal structures of the gallium and indium complexes confirm the presence of unsupported metal-metal bonds in both cases. The features of the solution H-1- and P-31{H-1}-NMR spectra suggest that both dimers are fluxional in solution. (C) 1999 Elsevier Science S.A. All rights reserved.},

	abstract = {Spatially resolved emission and absorption intensities from the indium 303.93-nm resonance line were measured in a furnace atomization plasma excitation spectrometry (FAPES) source. These measurements show that the spatial structure observed in the analyte emission is due to two effects, The first is the spatial distribution of analyte atoms in the source. The absorption measurements show that this spatial distribution is fairly uniform. There is a slight gradient, with analyte concentrations increasing from the cuvette wall to the center electrode. The fine structure in the emission intensity profiles must therefore be caused by the dependence of the degree of analyte excitation on position within the cuvette. This structure suggests that the FAPES source operates as an atmospheric-pressure radio-frequency glow discharge. Negative glows are seen adjacent to the graphite cuvette wall and center electrode.},

Particularly, 3-hydroxy-5-methyl-(N-methylformamido)fur (Hahm) and its Al and Ga complexes (M(ahm)(3)) have been prepared and thoroughly characterized by a variety of techniques, in the solid state and in solution. Solution equilibrium studies (mu = 0.6 M NaCl, 25 degrees C) uncovered a complicated set of equilibria in the Al3+/Hahm system; the solution potentiometric data were best explained by the presence of mixed ligand (HL = Hahm, L(-) = ahm(-)) hydroxo species [Al-3(OH)(4)L(3)](2+) and [AI(OH)(2)L(2)](-), in addition to the expected [AlL(n)]((3-n)+) (n = 1, 2, 3) species. Further solution studies at HL:M ratios of 3:1 (mu = 0.15 M NaCl, 25 degrees C) showed that Hahm is a relatively weak complexing agent for both Al and Ga, forming tris-ligand species with overall formation constants of 10(19.5) and 10(20.6), respectively.},
