Online‐Infrarotspektroskopie in der Bioprozessanalytik
Authors: Haake C. , Landgrebe D. , Scheper T. , Rhiel M. , Rhiel M. 
Published: August 2009

AbstractIn der Bioverfahrenstechnik ist es von entscheidender Bedeutung, Zustandsgrößen zeitnah zum tatsächlichen Prozess zu beobachten. Eine solche in situ‐Analyse ermöglicht eine akkurate Prozesssteuerung und trägt somit zur Erhöhung der Produktivität sowie der Reproduzierbarkeit bei. Ebenso lassen sich durch eine optimierte Steuerung Verbrauchskosten senken. Molekülschwingungen vieler organischer Verbindungen zeigen spektrale Signaturen im IR‐Bereich. Aufgrund dessen bieten sich für eine Prozessüberwachung verschiedene Infrarotsensoren an. Durch die Verwendung dieser nicht‐invasiven, optischen Sensoren ist gewährleistet, dass die Messungen keinen Einfluss auf den Kultivierungsvorgang haben. Das Kultivierungsmedium wird weder durch Probenentnahme verbraucht, noch beeinflusst. Es können unterschiedlichste chemische Komponenten des Kultivierungsmediums erfasst werden. Dazu gehören Nährstoffe, Wachstumsfaktoren und verschiedene Metabolite sowie die Biomasse selbst. Dieser Übersichtsartikel bietet einen Einblick in die verschiedenen Anwendungen der Infrarotspektroskopie im Bereich der Bioprozesstechnik. Es werden die verschiedenen Techniken dieser Methode aufgeführt sowie eine Überblick über aktuelle Arbeiten gegeben.

Authors: YU Wei , PENG Hui , ZHANG Haibo , ZHOU Xiaohai 
Published: August 2009

AbstractA novel series of morpholinium salts, N‐alkyl‐N‐methylmorpholinium salts (Mor1,nX, n=10, 12, 14, 16, X=BF4−) and Brönsted acidic N‐hexadecyl morpholinium salts (Mor16X, X=BF4−, CH3SO3− and p‐CH3C6H4SO3−) were synthesized. And their mesomorphic properties were characterized by differential scanning calorimetry and polarized optical microscopy. The single crystal X‐ray diffraction and the detailed temperature dependent small angle X‐ray diffraction were used to investigate the molecular structure of Mor1,16BF4. These results suggested that the favor the formation and stabilization of mesogenic compounds. And hydrogen bonds between the BF4− and morpholinium cations contributed to the conformational change of phase transition of Mor1,16BF4.

Authors: LI Fuan , LIU Hongling , LI Guopeng , TAO Ruojie 
Published: August 2009

AbstractA new dissymmetrical Schiff base copper precursor complex KCuL and a cis‐heterotrinuclear complex with the chemical formula [(CuL)2Mn(H2O)2]·CH3OH, have been synthesized and characterized by means of elemental analysis and IR, where H3L= (E)‐N‐[2‐(5‐chloro‐2‐hydroxybenzylideneamino)ethyl]‐2‐hydroxybenzamide. The crystal structure of the cis‐heterotrinuclear complex was determined by X‐ray analysis. Each cell unit of the complex contains one neutral cis‐heterotrinuclear molecule and two disordered methanol molecules. The central Mn2+ ion is located at the site of O6 with a distorted octahedral geometry, and two coordination anions [CuL]− are aligned in cis‐configuration. The magnetic properties indicate that the trinuclear complex not only has antiferromagnetic interactions in the internal trinuclear molecule but also has weak ferromagnetic interactions between the trinuclear units. The best‐fit parameters are J= −12.1 cm−1, g=2.20 and zj′=1.37 cm−1.

Published: August 2009

AbstractThree di‐ and tri‐branched pyridinium salts with ferrocene ends and thienyl or bithienyl bridges, (E,E)‐N‐methyl‐2,4,6‐tris{2‐[5‐(2‐ferrocenylvinyl)thien‐2‐yl]vinyl} pyridinium iodide, (E,E)‐N‐methyl‐2,6‐bis‐ {2‐[5′‐(2‐ferrocenylvinyl)‐2,2′‐bithien‐5‐yl]vinyl} pyridinium iodide, and (E,E)‐N‐methyl‐2,4,6‐tris‐{2‐[5′‐(2‐ferrocenylvinyl)‐2,2′‐bithien‐5‐yl]vinyl}pyridinium iodide, were designed and successfully synthesized. The electrochemical properties of these compounds were primarily investigated, showing that most of these multiferrocenyl pyridinium salts are potential electrochemical molecular materials with good oxidation‐reduction reversibility.
Cross‐aldol Condensation of Cycloalkanones and Aromatic Aldehydes in the Presence of Nanoporous Silica‐based Sulfonic Acid (SiO2‐Pr‐SO3H) under Solvent Free Conditions
Authors: MOHAMMADI ZIARANI Ghodsi , BADIEI Alireza , ABBASI Alireza , FARAHANI Zahra 
Published: August 2009

AbstractThe aromatic aldehydes underwent cross aldol condensation with cycloalkanones in the presence of a catalytic amount of nanoporous silica‐based sulfonic acid (SiO2‐Pr‐SO3H) under solvent‐free conditions to afford the corresponding α,α′‐bis(substituted benzylidene)cycloalkanones in excellent yields with short reaction time without any side reactions. This method is very general, simple and environmentally friendly in contrast with other existing methods. SiO2‐Pr‐SO3H was proved to be an efficient heterogeneous solid acid catalyst, which could be easily handled and removed from the reaction mixture by simple filtration, and also recovered and reused without loss of reactivity.
An Oligonucleotide‐based Fluorescence Sensor for Mercury(II) in Aqueous Solutions
Authors: WU Huiwang , LIU Xueping , JIANG Jianhui , SHEN Guoli , YU Ruqin 
Published: August 2009

AbstractA highly selective fluorescence sensor was developed for Hg(II) ion detection in aqueous solutions based on the selective binding of Hg(II) ions with a pair of thymine‐thymine mismatch. The sensor consists of two DNA probes functionalized with a fluorophore (fluorescein, F) and a quencher (tetramethyl rhodamine, Q) moiety separately. This pair of DNA probes contains two pairs of thymine‐thymine mismatches used to detect Hg(II) ions. In the presence of Hg(II) ions, thymine‐Hg2+‐thymine was formed between thymine residues of probes. From that, the interaction of the two DNA probes increased. Thus, the DNA probes formed a double‐stranded structure. Both the fluorophore and quencher were brought close to each other leading to the fluorescence resonance energy transfer (FRET) between F and Q. Under the optimum conditions, the sensor was used to detect the Hg(II) ions from 50 to 1000 nmol·L−1 with a regression equation y=5281.13−1650.56 lg[Hg2+] (R2=0.985). The linear range covers 100 to 500 nmol·L−1, and the limit of detection (LOD) is 79 nmol·L−1. The disturbance of some co‐existing metal ions was explored, and no significant fluorescence quenching in the presence of 1.0 μmol·L−1 other metal ions was observed. The fluorescence sensor has good sensitivity and selectivity for Hg(II) ions providing a rapid, simple and low cost method for the detection of mercury(II) ions in aqueous solutions.

Authors: LI Yuling , GU Dagong , XU Xiaoping , JI Shunjun 
Published: August 2009

AbstractRing‐opening of two types of N‐tosyl aziridines with hydroxyl compounds has been studied. The aziridines could react smoothly with alcohols in the presence of functional ionic liquid [hmim]HSO4 to afford the corresponding β‐amino ethers in moderate to good yields with high regioselectivity. The recyclable property of [hmim]HSO4 was demonstrated in the process.

Anion Recognition Using Novel and Colorimetric Tweezer Receptors: 1,3‐Phenylenedi(carbonylhydrazone) in Aqueous‐organic Binary Solvents
Authors: ZHANG Youming , WANG Aixia , CAO Cheng , LENG Yanli , WEI Taibao 
Published: August 2009

AbstractTwo novel artificial tweezer receptors 1,3‐phenylenedi(carbonylhydrazone) derivatives with a symmetrical structure have been synthesized. Receptor 3a [1,3‐di(salicylidenehydrazinocarbonyl)benzene] for anions (F−, Cl−, Br−, I−, AcO−, HSO4−, H2PO4−, ClO4−) was investigated by UV‐Vis spectroscopy in DMSO and even 85% DMSO‐15% H2O binary solutions, respectively. Remarkable color changes from colorless to yellow were observed by the naked‐eye upon addition of AcO−, F− and H2PO4− to the solution of receptor 3a. The 1H NMR signals indicated that the receptor 3a underwent deprotonation after the addition of an excess of fluoride anion. In particular, the anion recognition was successfully applied to CH3COONa in 15% H2O‐85% DMSO. These findings were expected to be of significance for designing and developing novel color‐based anion sensors operated in aqueous media.

Authors: Bradley Deborah , Rathkopf Dana , Dunn Rodney , Stadler Walter M. , Liu Glenn , Smith David C. , Pili Roberto , Zwiebel James , Scher Howard , Hussain Maha 
Published: August 2009

AbstractBACKGROUND:This phase 2 trial was designed to evaluate the efficacy of vorinostat in chemotherapy‐pretreated patients with metastatic castration‐resistant prostate cancer.METHODS:Patients with disease progression on 1 prior chemotherapy, a prostate‐specific antigen (PSA) ≥5 ng/mL, and adequate organ function were treated with 400 mg vorinostat orally daily. The primary endpoint was the 6‐month progression rate. Secondary endpoints included safety, rate of PSA decline, objective response, overall survival, and effects of vorinostat on serum interleukin‐6 (IL‐6) levels.RESULTS:Twenty‐seven eligible patients were accrued. The median number of cycles delivered was 2 (range, 1‐7). All patients were taken off therapy before 6 months. The best objective response in the eligible patient was stable disease in 2 (7%) patients. No PSA decline of ≥50% was observed. There was 1 grade 4 adverse event (AE), and 44% of patients experienced grade 3 adverse events. The most common adverse events were fatigue (81%), nausea (74%), anorexia (59%), vomiting (33%), diarrhea (33%), and weight loss (26%). Median time to progression and overall survival were 2.8 and 11.7 months, respectively. Median IL‐6 levels (pg/mL) were higher in patients removed from the protocol for toxicity compared with progression at all time points, including baseline (5.2 vs 2.1, P = .02), Day 15 Cycle 1 (9.5 vs 2.2, P = .01), Day 1 Cycle 2 (9.8 vs 2.2, P = .01), and end of study (11.0 vs 2.9, P = .09).CONCLUSIONS:Vorinostat at this dose was associated with significant toxicities limiting efficacy assessment in this patient population. The significant association between IL‐6 levels and removal from the study for toxicities warrants further investigation. Cancer 2009. © 2009 American Cancer Society.
Image‐guided ThinPrep Papanicolaou tests and cotesting with high‐risk human papillomavirus in women aged 30 years and older in a low‐risk private practice population
Authors: Ge Yimin , Smith Debora , Schwartz Mary R. , Mody Dina R. 
Published: August 2009

AbstractBACKGROUND:Screening for cervical cancer precursors has evolved considerably with the introduction of new technologies to improve the early detection of disease. The objective of this study was to analyze the accuracy and effectiveness of combined screening with cytology and high‐risk human papillomavirus (HR‐HPV) testing in a low‐risk population of women aged ≥30 years.METHODS:Consecutive unselected samples from a group of 1871 women aged ≥30 years were screened with image‐guided ThinPrep tests and HR‐HPV tests during a 6‐month period. Histologic follow‐up was reviewed among women with positive HR‐HPV tests.RESULTS:A total of 85 (4.5%) women had positive HR‐HPV tests. In 48 HR‐HPV–positive women with follow‐up biopsies, 41 (85%) were found to have histologic abnormalities. Thirty‐three (1.9%) women with cytologically normal Papanicolaou (Pap) tests harbored HR‐HPV, and a cervical intraepithelial neoplasia (CIN) 2+ lesion was detected in 1 (16%) of 6 women with histologic follow‐up. Conversely, 2 (28%) of 7 women with high‐grade intraepithelial lesion on cytology tested negative for HR‐HPV during the same period. A case of serous carcinoma with atypical glandular cells on cytology was also negative for HR‐HPV, as expected.CONCLUSIONS:In this low‐risk population of women aged ≥30 years, histology‐confirmed CIN2+ lesions were identified in women with negative cytology and positive HR‐HPV tests, as well as in those with positive cytology and negative HR‐HPV tests. Because both cytology and HPV testing alone missed significant lesions, cotesting with Pap and HR‐HPV in women aged ≥30 years appears to be a reasonable option in a low‐risk population.
