	abstract = {Novel complexes of Ga3+ and In3+ were synthesized with two hetero donor phosphinophenolate ligands (PO-, ortho-phenoxydiphenylphosphine; MePO-, 5-methyl-2-phenoxydiphenylphosphine). RPO- (R = H, Me) binds in a bidentate fashion through both the hard O and the soft P donor atoms to In3+, whereas, it only binds Ga3+ through the O donor. Electrochemical synthesis proved to be a practical synthetic approach to In-2(PO)(3)Cl-3, In(PO)(3) and In(MePO)(3). [In(MePO)(H2O)Cl-2](2) and Ga(HPO)Cl-3 were synthesized from MCl3 (M = In and Ga, respectively). Both dimetallic indium complexes, [In(MePO)(H2O)Cl-2](2) and In-2(PO)(3)Cl-3, incorporate phenolate oxygen atoms bridging the two metal ions. Each pair of In atoms are in a distorted octahedral geometry in each complex, with the former complex having a coordination sphere of PO3Cl2 for both indium metal ions and the latter showing a coordination sphere of PO3Cl2 for one indium and P2O3Cl for the other. Ga(HPO)Cl-3 is a zwitterionic complex, with Ga having a OCl3 coordination core. All these complexes were fully characterized by a variety of techniques including X-ray crystallography.},

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.

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.},

Both metals form [M(H3L)](-), [M(H2L)](2-), [M(HL)](3-) and [ML](4-) complexes and in addition Cu2+ forms [ML(OH)](5-) complexes.

With both H(6)TAPS and H(6)TAMS, Ni2+ is co-ordinated by all six ligand donor atoms, probably in an octahedral manner. In the Cu2+ complexes the axial sites are only weakly co-ordinating: with H(6)TAPS the ligand uses an N3O2 donor set to bind Cu2+ and the sixth site is occupied by either hydroxide or phenolate oxygen; with H(6)TAMS, the ligand uses either an N2O3 or an N3O2 donor set to bind Cu2+, and hydroxide co-ordinates in the sixth position.},

	abstract = {The maltolate compound of aluminum (Al), tris(maltolato)aluminum(III), has been demonstrated to be quite toxic after central administration and in cell cultures. However, reports of peripheral Al-maltolate administration in vivo demonstrated un impressive neurological effects. We found no reports of Al-maltolate pharmacokinetics or its distribution into the central nervous system (CNS) after systemic administration. In the present study, we evaluated Al pharmacokinetics in serum and Al distribution into brain extracellular fluid (ECF) in rats following Al-maltolate administration. The pharmacokinetic studies revealed that systemic clearance, elimination half-life and mean residence time were 42 (+/- 5) ml/hr/kg, 2.2 (+/- 0.5) hr and 3.1 (+/- 0.7) hr [mean+/-SD), respectively. The steady state volume of distribution (V-ss) for Al-maltolate was 130 ml/kg. This V-ss suggests that Al-maltolate may exhibit limited distribution outside the vascular compartment, which is estimated to be approximate to 80 ml/kg in these rats. Previously, we used microdialysis (MD) probes to assess Al-citrate distribution into the CNS. MD was utilized in the present study to evaluate the CNS distribution of Al as a result of Al-maltolate administration. MD probes were implanted into the frontal cortex (FC) and jugular vein to sample Al from brain and blood ECF, respectively. Al was not measurable in FC MD probe dialysates after a 0.5 mmol/kg Al (as maltolate) bolus, but could be measured after steady state blood and brain ECF Al concentrations had been achieved. The Al brain/blood ra tio calculated from Al-maltolate steady state brain and blood MD samples was 0.04, significantly less than those calculated for other Al salts at equimolar Al doses. The present study suggests that unless it is administered centrally, Al-maltolate might render minimal neurological insult because of its minimal permeation into brain extracellular space.

	abstract = {The pharmacokinetics of selected aluminum-hydroxypyridinone (Al-HP) complexes were determined in rats to better understand the relationship between their disposition and elimination parameters and the safety of HPs in the chelation therapy of Al intoxication. Five complexes were administered as i.v. bolus doses of Al-HP (0.25 mmol/kg Al-0.75 mmol/kg HP). The Al-HP steady state volumes of distribution ranged from 220 to 871 ml/kg, suggesting that each complex distributed out of the vascular compartment (which should have been approximate to 65 ml/kg). Systemic clearances ranged from 189 to 906 ml/h per kg. Elimination half-lives (t(1/2)) and mean residence times ranged from 0.36 to 0.84 and 0.52 to 1.20 h, respectively. The Al-CP20 complex had a short t(1/2) and a midrange volume of distribution. It demonstrated no apparent toxicity, whereas myoclonic seizures were observed after Al-CP22, Al-CP24 and Al-CP94 administration. The most appropriate choice for Al chelation among the HPs tested may be CP20. Characterization of the distribution and elimination of Al-HP complexes improves the understanding of potential toxicity that may be associated with HP therapy of Al intoxication.},
