Abstract
ABSTRACT Iron is an essential trace element for both humans and bacteria. It plays a vital role in life, such as in redox reactions and electron transport. Strict regulatory mechanisms are necessary to maintain iron homeostasis because both excess and insufficient iron are harmful to life. Competition for iron is a war between humans and bacteria. To grow, reproduce, colonize, and successfully cause infection, pathogens have evolved various mechanisms for iron uptake from humans, principally Fe 3+ -siderophore and Fe 2+ -heme transport systems. Humans have many innate immune mechanisms that regulate the distribution of iron and inhibit bacterial iron uptake to help resist bacterial invasion and colonization. Meanwhile, researchers have invented detection test strips and coupled antibiotics with siderophores to create tools that take advantage of this battle for iron, to help eliminate pathogens. In this review, we summarize bacterial and human iron metabolism, competition for iron between humans and bacteria, siderophore sensors, antibiotics coupled with siderophores, and related phenomena. We also discuss how competition for iron can be used for diagnosis and treatment of infection in the future.

Abstract
Osteoarthritis, also known as degenerative arthritis or degenerative joint disease, is an epidemic disease that affects millions of people worldwide. Despite extensive recent work on the cellular biology of osteoarthritis, the precise mechanisms involved are still poorly understood and there is no effective treatment for this disease. The role of transforming growth factor-beta (TGF-β) in promoting chondrogenesis and inducing the expression of cartilage-specific extracellular matrix molecules to form cartilage is well-established. Historically, TGF-β has been considered to prevent osteoarthritis, but recent work suggests that TGF-β overexpression accelerates the progression of osteoarthritis in vivo. Clinically, it is therefore important to limit TGF-β expression while still providing effective treatment of osteoarthritis. One possible approach to achieve this effect would be to use a combination of TGF-β with other small molecular chemical compounds. Hypoxia promotes chondrogenesis and the usefulness of deferoxamine, a chelating agent that mimics hypoxia, in stimulating chondrogenesis has been investigated in clinical trials. In this study, we investigated the role of deferoxamine in TGF-β-induced chondrogenesis in pre-chondrogenic cells and examined whether deferoxamine synergizes with the TGF-β signaling pathway to promote chondrocyte differentiation.

Abstract
The antimalarial drug FR900098 was prepared from diethyl allylphosphonate involving the nitroso-ene reaction with nitrosocarbonyl methane as the key step followed by hydrogenation and dealkylation. The utilization of dibenzyl allylphosphonate as the starting compound allows one-step hydrogenation with dealkylation, which simplifies the preparative scheme further.

Abstract
The structural similarity between beta-lactam antibiotics, such as penicillin, and isoxazolidine-3,5-dicarboxylic acids led to the hypothesis that isoxazolidine-3,5-dicarboxylic acids could be effective analogs of beta-lactam antibiotics. The syntheses of relevant isoxazolidine-3,5-dicarboxylic acids from acylnitroso Diels-Alder adducts and subsequent biological testing have shown that these first examples are inhibitors of Escherichia coli X580.

Abstract
The empirical force field (EFF), developed by Prof. Lifson, was applied to the study of macrocyclic alkali ion carriers and to di- and tripodal and open chain siderophores and synthetic biomimetic molecules binding transition metals. The highly symmetric nature of these structures facilitated a favorable coordination geometry of the ligating groups about the metal, which helped organize the entire molecule into a fairly rigid structure. In our combined experimental-theoretical approach, EFF calculations were used to help predict likely candidates to synthesize, and provided a wealth of structural data to complement what we learned from the spectroscopic measurements, while feedback from these measurements allowed us to continue improving the EFF itself. The simple, highly modular design of the biomimetic analogs allowed rapid synthesis and systematic examination of a large number of related structures, as well as facilitating an efficient, piecewise conformational scanning for the theoretical calculations. In the early years, we focused on macrocyclic polylactones and lactams binding monovalent alkali ions, particularly the natural products enniatin and valinomycin, including inside a crystal lattice. Later we switched to bi- and tridentate siderophores, natural microbial iron carriers, and synthetic biomimetic analogs-in particular, of enterobactin, ferrichrome, and ferrioxamine B. Over the years a large number of biomimetic siderophores have been prepared, some active in a broad range of microorganisms while others are highly species specific. The results of this work have broad applications in many areas, including the design of novel drugs and antimicrobial agents, helical polymeric structures, and polynuclear metal complexes.

Abstract
To gain knowledge about biological iron mobilization, tripodal monotopic and ditopic hydroxamate ligands (1 and 2) are prepared, and their iron-chelating properties are investigated. Ligands 1 and 2 contain three Ala-Ala-beta-(HO)Ala units and three [Ala-Ala-beta-(HO)Ala](2) units connected with tris(alanylaminoethyl)amine, respectively, and form six-coordinate octahedral complexes with iron(III) in aqueous solution. Ligand 1 and 1 equiv of iron give Fe-1, and ligand 2 and 1 or 2 equiv of iron produce Fe(1)-2, or Fe(2)-2. These complexes exhibit absorptions at lambda(max) 425 nm of epsilon 2800-3000/Fe, characteristic of tris(hydroxamato)iron(III) complexes, and preferentially assume the Delta-cis configuration. Loading of Fe(III) on 1, 2, and M(III)-loaded ligands (M-1 and M(1)-2, M = Al, Ga, In) with ammonium ferric oxalate at pH 5.4 is performed, and the second-order rate constants of loading with respect to Fe(III) and the ligand or M(III)-loaded ligands are determined. The rates of loading of Fe(III) on M-1 increase in the order Al-1 < Ga-1 < In-1, and those on M(1)-2 in the order Al(1)-2 < Ga(1)-2 < Fe(1)-2 < In(1)-2, indicating that the dissociation tendency of M(III) ions from the hydroxamate ligand is an important factor. The iron complexes formed with 2 are subjected to an iron removal reaction with excess EDTA in aqueous pH 5.4 solution at 25.0 degrees C, and the collected data are analyzed by curve-fitting using appropriate first-order kinetic equations, providing the rate constants for the upper site and the lower site of 2. Similar analysis for FeM-2 affords removal rate constants for Fe(up)-2, M(up)-2, and Fe(low)-2, and the iron residence probability at each site. The protonation constants of the hydroxamate groups for 1 and 2 (pK(1,) pK(2), pK(3), and pK(1,) pK(2)., pK(6)) are determined, and the proton-independent stability constants for Fe-1, the upper site of Fe(2)-2, and the lower site of Fe(1)-2 are 10(28), 10(29), and 10(28.5), respectively.

Abstract
The ability of pathogens to obtain iron from transferrins, ferritin, hemoglobin, and other iron-containing proteins of their host is central to whether they live or die. To combat invading bacteria, animals go into an iron-withholding mode and also use a protein (Nramp1) to generate reactive oxygen species in an attempt to kill the pathogens. Some invading bacteria respond by producing specific iron chelators-siderophores-that remove the iron from the host sources. Other bacteria rely on direct contact with host iron proteins, either abstracting the iron at their surface or, as with heme, taking it up into the cytoplasm. The expression of a large number of genes (>40 in some cases) is directly controlled by the prevailing intracellular concentration of Fe(II) via its complexing to a regulatory protein (the Fur protein or equivalent). In this way, the biochemistry of the bacterial cell can accommodate the challenges from the host. Agents that interfere with bacterial iron metabolism may prove extremely valuable for chemotherapy of diseases.

Abstract
Dendrimeric polyphenylsulfides, -selenides, and -tellurides are prepared in high yield using propyloxy spacers to connect the phenylchalcogeno groups to the dendrimeric core. The selenides and tellurides catalyze the oxidation of bromide with hydrogen peroxide to give positive bromine species that can be captured by cyclohexene in two-phase systems. The corresponding sulfides show no catalytic activity. The increase in the rate of catalysis followed statistical effects for 1, 6, and 12 phenyltelluro groups. However, the increase in the rate of catalysis exceeds statistical contributions for the first few generations with 1, 3, 6, and 12 phenylseleno groups and suggested cooperativity among phenylseleno groups. The increase in catalytic rate was lost upon replacing all but one phenylseleno group with phenoxy groups. On the basis of H2O2 consumed, the dendrimer with 12 phenylseleno groups has a turnover number of >60 000 mol of H2O2 consumed per mole of catalyst.

Abstract
Combining three units of one of H-(alanyl)n-beta-(HO)alanyl peptides (n = 1-3) with nitrilotriacetic acid affords tripodal peptide hydroxamate ligands (1L, 1D, 2LL, 2DL, and 3LLL, where each L or D denotes the L- or D-alanyl residue). These ligands form six-coordinate octahedral complexes (Fe-1L, Fe-1D, Fe-2LL, Fe-2DL, and Fe-3LLL) with iron(III) in aqueous near neutral pH solution, and the stability and the chirality of the complexes formed depend on the alanyl residues incorporated. Thus Fe-2LL is the most stable against attack of H+ and OH- ions and the least labile in the iron(III) removal by EDTA. The CD spectra show a predominance of the A configuration for Fe-1D, Fe-2LL, Fe-2DL, and Fe-3LLL, but the opposite delta configuration for Fe-1L. These ligands and their gallium(III) complexes are studied by 1H NMR spectroscopy in DMSO-d6 solution. CD and NMR spectral analysis, aided by molecular model examinations, indicates that critical factors in controlling the configuration and the stability of the complexes are (1) the hydroxamate-carrying alanyl residue, (2) the expanse of an interior space in the ligand, and (3) an interstrand amide NH hydrogen bond; the latter bonding is possible with ligands 2LL and 2DL. A microbial growth promotion activity test shows that ligands 1L, 2LL, and 3LLL all act as iron-transporting agents.

Abstract
Inorganic complexes have long been utilized for many therapeutic purposes. They were used or tried, perhaps because of the general notion that inorganic compounds (e.g., metal complexes) are toxic and a controlled use of such a compound may suppress some biological process. In this review, we briefly outline the properties of several selected groups of inorganic complexes and how they can affect biological systems and contribute to human pathologies.
