“…However, in T H F saturated with dextrose (whose solubility is very small) most of the DBZF was decoillposed by 2 days' exposure to sunlight. A further experiment of this kind involved dihydroxyacetone (DHA), which is also an effective chelating agent for ~e~~ ions (18). Solutions in methanol and acetone, containing 2 moles DHA per mole DBZF, decomposed much faster than solutioils containing DBZF alone.…”

The photostabilities of various ferrocene derivatives in solution have been studied as a function of solvent and, to a lesser extent, of incident wavelength. Some substituted ferrocenes, like ferrocene itself, did not decompose in methanol solution on exposure to near-ultraviolet light or sunlight; the remainder decomposed rapidly. Solutions of some derivatives in a number of other solvents also proved susceptible to photolysis. Qualitative evidence suggests that solute-solvent interaction leads to photochemically unstable species. Ferric ions do not appear to be formed in significant quantities during the degradative processes.Of the substituted ferrocenes investigated in this work, p-acetophenylferrocene appears to have considerable merit as a relatively stable and therefore protective light absorber. None of the derivatives, however, is as stable as ferrocene, which is prohibitively volatile for most practical applications.

“…We believe that these alterations are independent: the decrease in lipid peroxidation is related, according to Lefkowith (1988), to the depressed levels of macrophages in the exudate as a result of the diet; the changes observed in Fe metabolism as a consequence of the PUFA-deficient diet cannot easily be explained and need further research. However, findings have been published on the interrelationship of dietary factors and Fe absorption (Davis & Deller, 1966;Van Campen, 1974;Monsen & Cook, 1979), and according to Van Dokkum ef al. (1983) an increase of linoleic acid (18 : 2n-6) intake causes a reduction in the Fe balance.…”

Carrageenan-induced granuloma and iron status in rats with dietary polyunsaturated fatty acid deficiency

et al. 1991

Sprague–Dawley rats were fed for 4 months on a control diet or a polyunsaturated-fatty-acid (PUFA)-deficient diet. The combined effects of iron overload (Fe dextran) or Fe deficiency (desferrioxamine) on carrageenan-induced granuloma were studied. PUFA deficiency induced changes in Fe metabolism, but no alterations in lipid peroxidation variables were observed. Inflammation implied an increase in lipid peroxidation, Fe storage and caeruloplasmin concentration, together with symptoms of anaemia. PUFA deficiency in inflamed rats gave rise to a lower inflammatory response (granuloma weight and prostaglandin E2concentration) and ethane exhalation. Fe overload potentiated inflammatory and lipid peroxidation processes, whereas Fe deficiency decreased them.

“…Fructose has been shown to chelate iron and other cations (2) and the possibility that the germination effects of fructose were due to its chelation properties was considered. Neither ethylenediaminetetraacetic acid (EDTA), citrate, nor any of a number of common chelating agents were able to stimulate initiation or duplicate the fructose effect in any way.…”

2-Phenylacetamide is an effective germinant for spores of five strains of Bacillus macerans, particularly in the presence of fructose. Benzyl penicillin, the phenyl acetamide derivative of penicillin, and phenylacetic acid are also good germinants. L-Asparagine is an excellent germinant for four strains. a-Amino-butyric acid is moderately effective. Pyridoxine, pyridoxal, adenine, and 2, 6-diaminopurine are potent germinants for NCA strain 7X I only. D-Glucose is a powerful germinant for strain B-70 only. D-Fructose and D-ribose strongly potentiate germination induced by other germinants (except L-asparagine) but have only weak activity by themselves. Niacinamide and nicotinamide-adenine dinucleotide, inactive by themselves, are active in the presence of fructose or ribose. Effects of pH, ion concentration, and temperature are described. Extensive studies on spore germination in the past 20 years have generally been limited to three
