  • Solvothermal synthesis of discrete cages and extended networks comprising {Cr(iii)3O(O2CR)3(oxime)3}2− (R = H, CH3, C(CH3)3, C14H9) building blocks

    Houton, E; Comar, P; Pitak, MB; Coles, SJ; Ryder, AG; Piligkos, S; Brechin, EK; Jones, LF (Royal Society of Chemistry (RSC), 2016-07-28)
    © 2016 The Royal Society of Chemistry. The synthesis, structural and magnetic characterisation of a family of related Cr(iii) cages are reported. Each member comprises {Cr(iii)3O(O2CR1)3(R2-sao)3}2- (R1 = H, CH3, C(CH3)3, C14H9; R2 = Me, Ph, tBu, C10H8) triangles linked by Na+ cations, resulting in either the discrete complexes [H3O][NEt4]2[NaCr(iii)6O2(O2C-C14H9)6(Naphth-sao)6] (1) and [Na4Cr(iii)6O2(O2CC(CH3)3)6(3,5-di-tBu-sao)6(MeCN)6] (3); or the extended networks [H3O]2[Na2Cr(iii)6O2(O2CH)6(Ph-sao)6(MeCN)2(H2O)2]n·4MeCN (2); [H3O][Na3Cr(iii)6O2(O2CCH3)6(Me-sao)6(MeCN)]n (4) and [Na2Cr(iii)3O(O2CCH3)3(Me-sao)3(H2O)6]n·3MeCN (5). Magnetic susceptibility data obtained for 2 and 4 reveal weak antiferromagnetic exchange between the Cr(iii) ions in the triangles.
  • Synthesis of an orthogonally protected polyhydroxylated cyclopentene from l-Sorbose

    Lo Re, D; Jones, L; Giralt, E; Murphy, P; School of Chemistry, National University of Ireland, Galway, University Road, Galway, Ireland. daniele.lore@irbbarcelona.org. (Wiley, 2016-07-06)
    © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim The use of l-sorbose in the synthesis of functionalized cyclopentene derivatives was accomplished. These cyclopentene derivatives are related to those found in naturally occurring jatrophane frameworks and in other bioactive compounds. The formation of allyl α-l-sorbopyranoside was a key synthetic step. Regioselective introduction of protecting groups was followed by the hydrolysis of the allyl glycoside to furnish a fully protected acyclic l-sorbose derivative. This acyclic intermediate was subsequently used to give an orthogonally protected polyhydroxylated cyclopentene, which has potential for further synthesis of bioactive compounds. The protected cyclopentene itself showed a clear cytotoxic activity when tested against a panel of human cancer cell lines (HT29, LS174T, SW620, A549, and HeLa cells).
  • Elucidating cylindrospermopsin toxicity via synthetic analogues: An in vitro approach

    Evans, DM; Hughes, J; Jones, LF; Murphy, PJ; Falfushynska, H; Horyn, O; Sokolova, IM; Christensen, J; Coles, SJ; Rzymski, P; et al. (Elsevier, 2019-06-10)
    © 2019 Elsevier Ltd Cylindrospermopsin (CYN) is an alkaloid biosynthesized by selected cyanobacteria, the cyto- and genotoxic properties of which have been studied extensively by in vitro and in vivo experimental models. Various studies have separately established the role of uracil, guanidine and hydroxyl groups in CYN-induced toxicity. In the present study, we have prepared five synthetic analogues that all possess a uracil group but had variations in the other functionality found in CYN. We compared the in vitro toxicity of these analogues in common carp hepatocytes by assessing oxidative stress markers, DNA fragmentation and apoptosis. All the analogues tested induced generation of reactive oxygen species, lipid peroxidation (LPO) and DNA fragmentation. However, the greatest increase in LPO and increase in caspase-3 activity, an apoptosis marker, was demonstrated by an analogue containing guanidine, hydroxyl and uracil functionalities similar to those found in CYN but lacking the complex tricyclic structure of CYN. We also report a crystal structure of an analogue lacking the hydroxyl group found in CYN which does not show intramolecular H-bonding interactions between the guanidine and the uracil functionalities. The observations made in this work supports the hypothesis that CYN toxicity is a result of an interplay between both of the uracil, hydroxyl and guanidine functional groups.
  • Exploring children's physical activity behaviours according to location: A mixed-methods case study

    Khawaja, Irfan; Woodfield, Lorayne; Collins, Peter; Benkwitz, Adam; Nevill, Alan (MDPI AG, 2019-11-18)
    The school environment is ideally placed to facilitate physical activity (PA) with numerous windows of opportunity from break and lunch times, to lesson times and extracurricular clubs. However, little is known about how children interact with the school environment to engage in PA and the other locations they visit daily, including time spent outside of the school environment i.e., evening and weekend locations. Moreover, there has been little research incorporating a mixed-methods approach that captures children's voices alongside objectively tracking children's PA patterns. The aim of this study was to explore children's PA behaviours according to different locations. Sixty children (29 boys, 31 girls)-35 key stage 2 (aged 9-11) and 25 key stage 3 (aged 11-13)-wore an integrated global positioning systems (GPS) and heart rate (HR) monitor over four consecutive days. A subsample of children (n = 32) were invited to take part in one of six focus groups to further explore PA behaviours and identify barriers and facilitators to PA. Children also completed a PA diary. The KS2 children spent significantly more time outdoors than KS3 children (p = 0.009). Boys engaged in more light PA (LPA) when on foot and in school, compared with girls (p = 0.003). KS3 children engaged in significantly more moderate PA (MPA) at school than KS2 children (p = 0.006). Focus groups revealed fun, enjoyment, friends, and family to be associated with PA, and technology, costs, and weather to be barriers to PA. This mixed methodological study highlights differences in the PA patterns and perceptions of children according to age and gender. Future studies should utilize a multi-method approach to gain a greater insight into children's PA patterns and inform future health policies that differentiate among a range of demographic groups of children.
  • ‘There is anointing everywhere': An interpretative phenomenological analysis of the role of religion in the recovery of black African service users in England

    Tuffour, Isaac (Wiley, 2020-01-08)
    Introduction Religion is an important impetus for recovery. However, there has been little work examining the role of religion in recovery for black African service users (BASUs) in England. Aim The aim of this study is to explore how religion influences recovery from mental illness for BASUs in England. Method 12 black African service users were purposively selected and interviewed using face‐to‐face semi‐structured interviews. Data was analysed using interpretative phenomenological analysis (IPA). Results The study generates fascinating insights that BASUs views about mental illness and recovery are influenced by Pentecostalism and traditional African healing systems. Discussion The participants' perceptions of their mental illness experiences and recovery which are characterised by the pragmatism of Pentecostalism and cultural beliefs are consistent with what is reported in the literature. Implications for Practice The findings of the study show that broad changes are needed to accommodate the religious coping of BASUs in their recovery journey.
