Catalytic Properties and Stability of the Heteropolytungstate [P2W21O71(H2O)3]6– in H2O2‐Based Oxidations
Authors: Donoeva Baira G. , Trubitsina Tatiana A. , Maksimov Gennadii M. , Maksimovskaya Raisa I. , Kholdeeva Oxana A. 
Published: October 2009

AbstractCatalytic properties of the sandwich‐type heteropolytungstate [P2W21O71(H2O)3]6– (1) in the selective oxidation of three representative organic substrates, methyl phenyl sulfide, cyclohexene, and cyclohexanol, with aqueous H2O2 have been studied in acetonitrile. With one equivalent of hydrogen peroxide, methyl phenyl sulfide readily produced the corresponding sulfoxide with 92–94 % selectivity at 95–97 % conversion. The substituent effect on the oxidation rates of the set of aryl methyl sulfides followed the Hammett free‐energy relationship (ρ = –0.85). The catalytic activity of heteropolyacid H‐1 in thioether oxidation was several times higher than the activity of its tetrabutylammonium salt, TBA‐1. In contrast, H‐1 was completely inactive in the oxidation of cyclohexanol, while TBA‐1 catalyzed this reaction effectively to give cyclohexanone with 94 % yield. Neither H‐1 nor TBA‐1 was active in the oxidation of cyclohexene. The catalytic performance of 1 in H2O2‐based oxidations in MeCN is similar to that of the Keggin heteropolyanion [PW12O40]3– (PW12) and differs significantly from the performance of the Venturello complex {PO4[W(O)(O2)2]4}3–. The stability of 1 and PW12 towards solvolytic destruction under turnover conditions (50–100 equiv. H2O2, 25–70 °C, 2–72 h) was confirmed by using 31P NMR, IR, and Raman spectroscopic techniques.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)

AbstractNovel potentially bioactive spiroaziridine‐oxindoles have been prepared by treatment of easily accessible 3‐ylideneoxindoles with N‐{[(4‐nitrophenyl)sulfonyl]oxy}carbamate (NsONHCO2Et) in the presence of CaO. These compounds gave new 3‐(aminoalkyl)oxindole derivatives through easy and regioselective reductive aziridine ring‐opening reactions.(© Wiley‐VCH Verlag GmbH & Co.

Comparison of body size estimation in adolescents with different types of eating disorders
Authors: Schneider Nora , Frieler Katja , Pfeiffer Ernst , Lehmkuhl Ulrike , Salbach‐Andrae Harriet 
Published: October 2009

AbstractObjectiveTo examine differences in body size estimation in adolescents with different types of eating disorders.MethodA total of 129 patients with eating disorders (Mage = 16.0 ± 1.8) and 354 healthy control participants (CP) (Mage = 15.2 ± 2.1) completed the EDI‐2 and were asked to estimate the circumference of selected body parts by using string (BID‐CA).ResultsCP showed an average overestimation of 8–16%, depending on the estimated body part. Eating disorder patients overestimated their body parts on average by about 30%. Thigh and waist estimations were the best variables for discriminating between patients with eating disorders and CP. No significant differences were found between bulimia nervosa and anorexia nervosa patients.ConclusionsBody image distortion plays an important role in both anorexia nervosa and bulimia nervosa. The BID‐CA is well suited to discriminate between healthy and disordered overestimation of body parts. Copyright © 2009 John Wiley & Sons, Ltd and Eating Disorders Association.
Promoter demethylation and chromatin remodeling by green tea polyphenols leads to re‐expression of GSTP1 in human prostate cancer cells
Authors: Pandey Mitali , Shukla Sanjeev , Gupta Sanjay 
Published: October 2009

AbstractEpigenetic silencing of gluthathione‐S‐transferase pi (GSTP1) is recognized as being a molecular hallmark of human prostate cancer. We investigated the effects of green tea polyphenols (GTPs) on GSTP1 re‐expression and further elucidated its mechanism of action and long‐term safety, compared with nucleoside‐analog inhibitor of DNA methyltransferase (DNMT), 5‐aza‐2′‐deoxycitidine. Exposure of human prostate cancer LNCaP cells to 1–10 μg/ml of GTP for 1–7 days caused a concentration‐ and time‐dependent re‐expression of GSTP1, which correlated with DNMT1 inhibition. Methyl‐specific‐PCR and sequencing revealed extensive demethylation in the proximal GSTP1 promoter and regions distal to the transcription factor binding sites. GTP exposure in a time‐dependent fashion diminished the mRNA and protein levels of MBD1, MBD4 and MeCP2; HDAC 1–3 and increased the levels of acetylated histone H3 (LysH9/18) and H4. Chromatin immunoprecipitation assays demonstrated that cells treated with GTP have reduced MBD2 association with accessible Sp1 binding sites leading to increased binding and transcriptional activation of the GSTP1 gene. Exposure of cells to GTP did not result in global hypomethylation, as demonstrated by methyl‐specific PCR for LINE‐1 promoter; rather GTP promotes maintenance of genomic integrity. Furthermore, exposure of cells to GTP did not cause activation of the prometaststic gene S100P, a reverse response noted after exposure of cells to 5‐aza‐2′deoxycitidine. Our results, for the first time, demonstrate that GTP has dual potential to alter DNA methylation and chromatin modeling, the 2 global epigenetic mechanisms of gene regulation and their lack of toxicity makes them excellent candidates for the chemoprevention of prostate cancer.
Preferred drifting along the DNA major groove and cooperative anchoring of the p53 core domain: mechanisms and scenarios
Authors: Pan Yongping , Nussinov Ruth 
Published: October 2009

AbstractWhile the importance of specific p53‐DNA binding is broadly accepted, the recognition process is still not fully understood. Figuring out the initial tetrameric p53‐DNA association and the swift and cooperative search for specific binding sites is crucial for understanding the transactivation mechanism and selectivity. To gain insight into the p53‐DNA binding process, here we have carried out explicit solvent molecular dynamic (MD) simulations of several p53 core domain‐DNA conformations with the p53 and the DNA separated by varying distances. p53 approached the DNA, bound non‐specifically, and quickly drifted along the DNA surface to find the major groove, cooperatively anchoring in a way similar to the specific binding observed in the crystal structure. Electrostatics was the major driving force behind the p53 movement. Mechanistically, this is a cooperative process: key residues, particularly Lys120 and Arg280 acted as sensors; upon finding their hydrogen‐bonding partners, they lock in, anchoring p53 into the major groove. Concomitantly, the DNA adopted a conformation that facilitated p53 easy access. The initial non‐specific core domain‐DNA contacts assist in shifting the DNA and the p53 substrates toward conformations “ready” for specific major groove binding, with subsequent optimization of the interactions. This work is an invited contribution for the special issue of the Journal of Molecular Recognition dedicated to Professor Martin Karplus. Copyright © 2009 John Wiley & Sons, Ltd.
