Enantioselectivity of hydroxylation of racemic piperitone by fungi
Authors: Grudniewska Aleksandra , Gniłka Radosław , Wawrzeńczyk Czesław 
Published: April 2010

AbstractThe biotransformation of racemic piperitone ((±)‐1) was investigated using four strains of fungi selected in the screening procedure. The substrate was transformed by Botrytis cinerea AM235, Absidia cylindrospora AM336, Absidia coerulea AM93, and Absidia glauca AM177 into more polar metabolites. The transformation of racemic piperitone ((±)‐1) catalyzed by B. cinerea AM235 gave 7‐hydroxypiperitone (2) as the only product. The biotransformation of (±)‐1 by A. cylindrospora AM336 afforded mixture of three products: (−)‐(R)‐7‐hydroxypiperitone ((−)‐2), (+)‐(4S,6R)‐trans‐6‐hydroxypiperitone ((+)‐3), and (+)‐(4R,6R)‐cis‐6‐hydroxypiperitone ((+)‐4). The transformation of this substrate ((±)‐1) by A. coerulea AM93 gave (±)‐7‐hydroxypiperitone ((±)‐2), (−)‐(4R,6S)‐trans‐6‐hydroxypiperitone (−)‐3), and (−)‐(4S,6S)‐cis‐6‐hydroxypiperitone ((−)‐4). The last strain studied, A. glauca AM177, converted racemic piperitone ((±)‐1) to four products: (+)‐(S)‐7‐hydroxypiperitone (2), (+)‐(4S,6R)‐trans‐6‐hydroxypiperitone ((+)‐3), (±)‐cis‐6‐hydroxypiperitone ((±)‐4), and 8‐hydroxypiperitone (5).

Herstellung von Wandkatalysatoren für Mikrostrukturreaktoren mittels der Niederdruckspritztechnologie
Authors: Schwarz T. , Döring H. , Klemm E. , Schirrmeister S. 
Published: May 2010

AbstractStark exotherme chemische Reaktionen können in Mikrostrukturreaktoren wegen ihrer hohen Wärmeabfuhrleistung nahezu isotherm durchgeführt werden. Bei exothermen, heterogen katalysierten Gasphasenreaktionen können Mikrostrukturreaktoren mit Wandkatalysatoren eingesetzt werden, um die freiwerdende Reaktionswärme effizient über die Wand an das Wärmeträgermedium abzuführen. Die reproduzierbare und automatisierbare Herstellung von mechanisch stabilen, ausreichend porösen, aktiven und selektiven Wandkatalysatoren mit Dicken von mehreren 100 μm stellt dabei die entscheidende Schlüsseltechnologie dar. Im Rahmen der vorliegenden Arbeit wird gezeigt, dass die Niederdruckspritztechnologie eine solche Schlüsseltechnologie ist. Entscheidend sind dabei die vom jeweiligen Katalysatorsystem abhängenden optimalen Spritzbedingungen wie insbesondere der optimale Spritzdruck. Optimale Schichten besitzen Kavitäten im Mikrometerbereich, da dann die für einen großtechnischen Reaktor notwendige hohe mechanische Stabilität gewährleistet ist.
Hochdurchsatzmethoden zur Entdeckung und Optimierung kristalliner poröser Materialien
Authors: Stock N. 
Published: May 2010

AbstractHochdurchsatz (HD)‐Methoden erlauben eine systematische und effiziente Untersuchung komplexer Parameterräume, wie sie oft bei Solvothermalsynthesen beobachtet werden. Ihr Einsatz ermöglicht es, schneller neue Verbindungen zu entdecken, Synthesebedingungen zu optimieren bzw. Reaktionstrends ausfindig zu machen. Mit einem unterschiedlichen Ausmaß an Parallelisierung, Miniaturisierung und Automatisierung der einzelnen Arbeitsschritte wurden innerhalb des letzten Jahrzehnts einige HD‐Methodiken entwickelt, deren Einsatz zu neuen herausragenden mikroporösen Verbindungen im Bereich der Zeolithe, ZIFs (zeolithic imidazolate frameworks) und MOFs (metal‐organic frameworks) geführt haben.
Poröse Materialien – Kurze Vor‐ und Frühgeschichte
Authors: Robens E. 
Published: May 2010

AbstractHolzkohle kann als erstes synthetisches Material der Menschheit angesehen werden. Holz‐ und Knochenkohle sowie oberflächenaktive Erden wurden schon in vorgeschichtlichen Technologien vielfältig benutzt. Die systematische Erforschung poröser Adsorbentien beginnt 1773 mit Scheele, Priestley und Fontana. Zu Anfang des 19. Jahrhunderts war die Zuckerraffinerie die erste industrielle Nutzung, Ende des 19. Jahrhunderts wurde die großindustrielle Fabrikation poröser Materialien aufgenommen und mit der Wende zum 20. Jahrhundert wurden viele neuartige poröse Materialien synthetisiert und erforscht.

Published: April 2010

AbstractFinding an appropriate mechanism of oxygen reduction reaction, without having kinetic parameters and intermediate species at hand, is an impossible task. In view of the fact that this reaction is one of the important reactions, it was tried to overcome this problem through computing the kinetic parameters by means of Ag/GC rotating disc electrode in an acidic solution. Using this electrode, two values were obtained for electron transfer coefficient and reaction order was calculated through relative equations. Based on this information, an ECE (electrochemical chemical electrochemical) mechanism has been proposed.

Diels‐Alder Reactions of Ethyl α‐Bromoacrylate with Open‐chain Dienes–Synthesis of Ethyl 1,3‐/ 1,4‐Cyclohexadienecarboxylates
Authors: Li Yingjie , Wang Quanrui , Andreas Goeke 
Published: April 2010

AbstractThe Diels‐Alder reactions of ethyl α‐bromoacrylate 1 with open‐chain dienes 2 were conducted under thermal or Lewis acid‐catalysis conditions. In most cases, the cyclic adducts of 1‐bromocyclohex‐3‐enecarboxylates 3 were formed in high yields with good regio‐ and stereoselectivity. Subsequent E2‐elimination by treatment with DBU provided the corresponding 1,3‐ or 1,4‐cyclohexadienecarboxylates depending on the relative configuration of the products. Starting from myrcene (7‐methyl‐3‐methyleneocta‐1,6‐diene) the reaction sequence afforded the ester precursor of Georgywood with good yields.

Published: May 2010

AbstractBackgroundConsidering that prehypertension is associated with an increase in cardiovascular risk, hypoadiponectinemia seems to be a predictor of hypertension.HypothesisThis study investigated whether adiponectin plasma levels are affected in Brazilian obese prehypertensives compared with those in normotensives and hypertensives.MethodsThe study involved 96 multiethnic obese subjects (mean age = 42.8–11.9 years; BMI = 35.7–7.3 kg/m2). Fasting plasma adiponectin and serum insulin were determined by radioimmunoassay. Insulin resistance was estimated by HOMA‐IR. Blood pressure was recorded using a calibrated automated sphygmomanometer.ResultsAdiponectin concentrations were significantly lower in prehypertensives compared with those in normotensives, but hypertensives exhibited the lowest adiponectin concentrations of all. Regarding the values of HOMA‐IR, both prehypertensives and hypertensives were significantly more insulin resistant when compared with normotensives. When normotensives and prehypertensives were classified according to the 50th percentile of adiponectin (≤ vs > 6.5 mg/ml) a logistic regression was performed to estimate the association of this adipokine with hypertension, the lower the plasma adiponectin values, the greater the association. A multivariate linear regression analysis adjusted for cardiometabolic factors showed that systolic blood pressure increased by 1.612 mm Hg for 1 µg/mL reduction in adiponectin plasma levels (P < 0.01).ConclusionOur findings have shown that hypoadiponectinemia is associated with prehypertension in obese individuals of multiethnic origin.

Swallowing‐induced Atrial Tachyarrhythmia Triggered by Salbutamol: Case Report and Review of the Literature
Authors: Tandeter H. , Kobal S. , Katz A. 
Published: May 2010

AbstractCaseA 49‐year‐old patient experienced chest discomfort while swallowing. On electrocardiogram, episodes of atrial tachyarrhythmia were recorded immediately after swallowing; 24‐hour Holter monitoring recorded several events. The arrhythmia resolved after therapy with atenolol, but recurred a year later. The patient noticed that before these episodes he had been using an inhalator of salbutamol. After stopping the β‐agonist, and after a week with the atenolol, the arrhythmia disappeared.DiscussionSwallowing‐induced atrial tachyarrhythmia (SIAT) is a rare phenomenon. Fewer than 50 cases of SIAT have been described in the literature. This article summarizes all the cases published, creating a comprehensive review of the current knowledge and approach to SIAT. It discusses demographics, clinical characteristics and types of arrhythmia, postulated mechanisms of SIAT, and different treatment possibilities such as medications, surgery, and radiofrequency catheter ablation (RFCA).ConclusionSalbutamol is presented here as a possible trigger for SIAT. Although it is difficult to define causality in a case report, it is logical to think that a β‐agonist like salbutamol (known to induce tachycardia) may be the trigger of adrenergic reflexes originating in the esophagus while swallowing and that a β‐blocker such as atenolol (that blocks the adrenergic activity) may relieve it.

Authors: Wang Cuiping , Yan Jinchuan , Yang Ping , Du Rongzeng , Chen Guanghua 
Published: May 2010

AbstractBackgroundRecently, CD40 polymorphism was found to be associated with acute coronary syndromes. However, few study was involved in the relationship between CD40 polymorphism and the risk of the vulnerable plaque to rupture so far.Materials and MethodsA total of 699 patients who have received coronary angiography were divided into 3 groups according to the morphological division of the plaques: complex lesions (343 cases), smooth lesions (131 cases), and control group (225 cases).The gene polymorphism was measured by the polymerase chain reaction and restriction fragment length polymorphism (PCR‐RFLP) and identified by sequencing.ResultsThe CC genotype and C allele frequency of the CD40 gene in the complex lesions group is significantly higher than in the smooth lesions group and the control group (P < .001), while the TT genotype frequency in the complex lesions group is significantly lower than that of the smooth lesions group and the control group (P < .001). The C allele increased disruption risk of the plaques in the complex lesions group as compared with the smooth lesions group (odds ratio [OR]: 1.697, 95% confidence interval [CI]: 1.273–2.261). No significant differences in genotypes or allele frequencies were found between the smooth lesions group and the control group.ConclusionOur results suggested that CD40 (−1C/T) polymorphism was associated with unstable coronary atherosclerotic plaques. The C allele frequency increased the risk of disruption of the coronary atherosclerotic plaques. Copyright © 2010 Wiley Periodicals, Inc.
