Structure Properties

This review paper is focused on the detailed consideration of the structure, properties and reactions of H2O2. The paper highlights the importance of revealing these processes’ mechanisms, since they have been insufficiently studied so far, or the related data have a fragmentary and incomplete character. A special attention is given to catalytic oxidation reactions, formation and properties of intermediates, their role in the natural environment.

Recent Attention

Pectin-based hydrogels for biomedical applications have attracted recent attention due to their low cost, large availability of the materials, and high levels of biocompatibility. Specifically, periodate-oxidized pectin has been combined with chitosan and gelatin to form different structures. However, hydrogen peroxide-mediated oxidation of pectin has not been studied for this application; furthermore, there is little information on the effect of the degree of oxidation on hydrogel characteristics nor has the feasibility of these systems as controlled drug delivery matrices been explored. Thus, the present work proposes to study the properties of gelatin-peroxide-oxidized pectin hydrogels as drug delivery systems in wound dressing applications. Combinations of pectin at different degrees of oxidation (high, low, and native pectin) and gelatin were analyzed and tested by swelling properties, reswelling from xerogel and aerogel forms, SEM, FTIR, and drug release. It was determined that hydrogels that contained oxidized pectin had improved swelling ratios and stability, at 32°C, compared to those with native pectin and only gelatin. The porosity of the oxidized pectin hydrogels allowed to have sustained and high release rates, which would make them an attractive alternative for wound dressings.

Catalytic Epoxidation

A set of dual functional small molecules (DFSMs) containing different amino acids has been synthesized and employed together with three different variants of the cytochrome P450 monooxygenase P450BM3 from Bacillus megaterium in H2O2-dependent oxidation reactions. These DFSMs enhance P450BM3 activity with hydrogen peroxide as an oxidant, converting these enzymes into formal peroxygenases. This system has been employed for the catalytic epoxidation of styrene and in the sulfoxidation of thioanisole. Various P450BM3 variants have been evaluated in terms of activity and selectivity of the peroxygenase reactions.

Bifunctional Compound

The reactions of 1,3,5-trimethylbiuret with dicyclohexylaminodichlorophosphine and with pyrrolidinodichlorophosphine furnished the triazaphosphinane-diones 1 and 2. Oxidation reactions of the 2-diorganoam ino-1,3,5-triorgano-1,3,5-triaza-2 λ3-phosphinane-4,6-diones 1, 2, and 4-9, as well as 2-fluoro-1,3,5-trimethyl-1,3,5-triaza-2λ3-phosphinane-4,6-dione 10 with hydrogen peroxide, elemental sulphur, phenyl azide, 1-adamantyl azide,p-nitrobenzoyl azide, tetrachloro-orthobenzoquinone, tetrabromo-orthobenzoquinone, 3,5-di-t-butyl-orthobenzoquinone, and hexafluoroacetone led to the respective oxidation products, 12-32, involving either λ4P or λ5P. In the reaction o f the P(III)C1 derivative 11 with 3-m ethyl-l,5-diphenyl-l,5- bis(trimethylsilyl)biuret the bifunctional compound 33 was produced. The new com pounds 1,2 and 12-33 were characterized via their 1H, 13C and 31P and, where appropriate, 19F NMR spectra. In the case o f the four compounds, 3 (previously described in the literature [2]), 13, 31, and 33, single crystal X-ray diffraction studies were conducted. Unusually for this type of heterocycle 3 displays a 1,4-diplanar ring conformation because o f the bulky aromatic substituents. 13 shows an envelope conformation. The hydrogen peroxide solvent molecule has crystallographic inversion symmetry, but may be disordered. In 31 the coordination geometry at phosphorus is trigonal bipyramidal. The five-membered ring shows a twist conform ation associated with the bulky trifluoromethyl groups. The exocyclic P-N bonds in 33 are unusually long.
