Signal amplification by reversible exchange (SABRE) is a para-hydrogen-based technique that utilises a metal complex, normally centred on iridium, to propagate polarisation from para-hydrogen-derived hydride ligands to spin-½ nuclei located in a bound substrate. To date, substrates possessing 1H, 13C, 15N, 19F, 31P, 29Si, and 119Sn nuclei have been polarised by this technique. The exact positioning of these nuclei has a direct bearing on the enhancement observed and so substrates must be chosen or synthesised with care in order to maximise polarisation transfer, and hence the resulting enhancement. The chemical composition of the metal complex must be similarly appraised, as the exchange rate of substrates and para-hydrogen is implicated heavily in efficient polarisation transfer. The nature of the polarisation transfer, whether homogenous or heterogeneous, is another important facet to consider here, as is conducting SABRE in water-based systems. This review discusses the physical and theoretical aspects of the SABRE experiment, as well as the applications of the SABRE technique, namely, the detection of analytes at concentrations far below what would be possible with conventional NMR techniques and the collection of hyperpolarised magnetic resonance images. Advances relating to utilising singlet states for SABRE, pulse sequence design and the nature of the polarisation transfer mechanism are also discussed, and the implications for future SABRE-based discoveries highlighted.

The photoassisted degradation of aromatic heterocycles (pyrrole, imidazole, pyrazole, isoxazole, oxazole and thiazole) and N-containing alicycles (aliphatic heterocycles: pyrrolidine, 4-butanelactam and 5-pentanelactam) was examined in liquid-solid dispersions. Complete mineralization (TOC) of the aromatic heterocycles was attained within ca. 1 h of UV irradiation of the TiO2/heterocycle system in acidic (pH 3), near-neutral (pH 6.0-7.6) and alkaline (pH 11) media. Mineralization kinetics were, in general, not appreciably influenced by the presence of acid but tended to be somewhat slower in alkaline media. N-alicycles were photomineralized more slowly than were the aromatics. The former could be mineralized in acidic and near-neutral media in less than 2 h, but not in alkaline media in which pyrrolidine, 4-butanelactam and 5-pentanelactam (and for comparison 4-butanelactone) were not mineralized even after 3 h of UV irradiation. Final products were, in all cases, CO2, NH4+ and NO3- ions and SO42- ions in the case of thiazole. Nitrogen (N2) gas was detected only during the photooxidation of pyrazole (contains two adjacent N heteroatoms) but not imidazole in which the N atom are separated by a C atom. The molar ratio NH4+/NO3- depended closely on the chemical structure of the substrates at the longer irradiation times. The site and mode of adsorption of these heterocycles onto the TiO2 particle surface were inferred from point charge calculations and the point of zero charge of the TiO2 (pHpzc ?6.7); the position of elecrophilic attack by the photogenerated {radical dot}OH radicals was deduced from calculated frontier electron densities.

Non-steroidal anti-inflammatory drugs are widely used therapeutic agents in the treatment of inflammation, pain and fever. Cyclooxygenase catalyzes the initial step of biotransformation of arachidonic acid to prostanoids, and exist as three distinct isozymes; COX-I, COX-II and COX-III. Selective COX-II inhibitors are a class of potential anti-inflammatory, analgesic, and antipyretic drugs with reduced gastrointestinal (GI) side effects compared to nonselective inhibitors. 3,4-Diarylisoxazole scaffold is recurrently found in a wide variety of NSAIDs, protein kinase inhibitors, hypertensive agents, and estrogen receptor (ER) modulators. In the present review, we document on the recent synthetic strategies of 3,4-diarylisoxazolyl scaffolds of valdecoxib and its relevant structural analogues.

Isoxazole, constituting an important family of five-membered heterocycles with one oxygen atom and one nitrogen atom at adjacent positions is of immense importance because of its wide spectrum of biological activities and therapeutic potential. It is, therefore, of prime importance that the development of new synthetic strategies and designing of new isoxazole derivatives should be based on the most recent knowledge emerging from the latest research. This review is an endeavor to highlight the progress in the chemistry and biological activity of isoxazole derivatives which could provide a low-height flying bird?s eye view of isoxazole derivatives to the medicinal chemists for the development of clinically viable drugs using this information.

A theoretical study was performed on the [3+2] cycloaddition (32CA) reaction of benzonitrile oxide, BNO 4, toward phenyl SF5-acetylene, PAC 5, in the presence of tetrahydrofuran (THF) at the DFT-B3LYP/6-31G?level. Calculated relative Gibbs free energies indicate that the studied 32CA reaction takes place via a complete C1C4 regioselective channel passing through TS1 affording the unique formal [3+2] cycloadduct CA1 observed experimentally. While based on the calculated Parr functions on the interacting sites of reagents this cycloaddition should proceed via energetically unfavorable C1C5 channel passing through TS2, a natural steric analysis evidently showed that destabilizing repulsion effects, rather than the electronic ones, are responsible for the complete C1C4 regioselective fashion provided by the considered 32CA reaction. An ELF topological analysis of the bonding changes along this 32CA reaction supports a non-concerted two-stage one-step molecular mechanism in which the formation of second O3C5 single bond takes place when the formation of first C1C4 one is almost complete.

During the past 25 years, the modulation of estrogen action by inhibition of 17beta-hydroxysteroid dehydrogenase types 1 and 2 (17beta-HSD1 and 17beta-HSD2), respectively, has been pursued intensively. In the search for novel treatment options for estrogen-dependent diseases (EDD)and in order to explore estrogenic signaling pathways, a large number of steroidal and nonsteroidal inhibitors of these enzymes has been described in the literature. The present review gives a survey on the development of inhibitor classes as well as the structural formulas and biological properties of their most interesting representatives. In addition, rationally designed dual inhibitors of both 17beta-HSD1 and steroid sulfatase (STS)as well as the first inhibitors of 17beta-HSD14 are covered.

Binuclear lanthanide(III)-siver(I) beta-diketonate chelates are effective NMR shift and relaxation reagents for substrates containing one or two multiply bonded nitrogen atoms, despite the fact that some of the substrates are able to react with lanthanide chelates alone.The silver cation is bonded to the nitrogen-nitrogen or nitrogen-carbon multiple bond.The lanthanide(III) chelate tetrakis anion is held in proximity to the substrate, without delocalization of spin density from the lanthanide to the studied nuclei (15N, 13C, 1H) of the substrate.Greater spectral simplification is achieved with a binuclear shift reagent than with a single lanthanide chelate in two ways.First, the complexation ability of the ? electron pair may be geater than that of the heteroatom lone pair when that of the latter is lowered owing to steric (azobenzene, trans-aldimine derivatives) or conjugative effects (benzonitrile is similar in this respect to heteroaryl substrates in which the heteroatom is devoid of basicity).Second, resolution may be far better preserved in cases where very strong binding to the lanthanide chelates results in extensive broadening of the NMR signals (imidazole, thiazole and oxazole derivatives).

Five-membered heterocyclic structures, which exist widely in biological systems and play an active role in various biochemical processes, have been studied extensively from a fundamental perspective. Here, the fragmentation patterns of isoxazole, a representative five-membered heterocycle, upon dissociative electron attachment (DEA) were examined carefully by comparing isoxazole’s products with those of its methylated derivatives. It was found that the most dominant DEA pathway occurs through the loss of hydrogen at C(3), which leads to ring opening by O-N bond cleavage at an energy of ?1.5 eV. The ring opening was investigated further for DEA to other related five-membered ring compounds, i.e., oxazole and thiazole. The DEA-induced hydrogen loss was much less pronounced or quenched completely in these two compounds and simultaneous ring-opening behavior was not detected. This observation is of special interest to applied fields, for example, the pharmaceutical industry, because several drugs that contain isoxazole substructures exhibit extensive ring opening during biotransformation.
