Authors: Elbashir Abdalla A. , Saad Bahruddin , Ali Abdussalam Salhin Mohamed , Saleh Muhammad Idiris , Aboul‐Enein Hassan Y.
Published: September 2008

A capillary electrophoretic (CE) method for the baseline separation of the enantiomers of primaquine diphosphate (PQ) and quinocide (QC) (a major contaminant) in pharmaceutical formulations is proposed. Both components were separated under the following conditions: 50 mm tris phosphate buffer (pH 3.0) containing 15 mm hydroxypropyl‐γ‐cyclodextrin (HP‐γ‐CD) as background electrolyte; applied voltage, 16 kV; capillary temperature, 25°C; detection wavelength, 254 nm; hydrostatic injection, 10 s. The separations were conducted using a 35 cm length and 50 µm i.d. uncoated fused silica capillary column. Under the optimized conditions, the components were successfully separated in about 5 min. Intraday precision of migration time and corrected peak areas when expressed as relative standard deviation ranged from 0.17 to 0.45 and 2.60 to 3.94%, respectively, while the interday precision ranged from 2.59 to 4.20 and 3.15 to 4.21%, respectively. After the validation exercise, the proposed method was applied for the determination of QC impurity in PQ formulations. Copyright © 2008 John Wiley & Sons, Ltd.
Experience in identifying the venous drainage of the adrenal gland during laparoscopic adrenalectomy
Authors: Parnaby Craig N. , Galbraith Norman , O'Dwyer Patrick J.
Published: September 2008

Laparoscopic adrenalectomy (LA) is the procedure of choice for most adrenal tumors. An important part of LA is the early identification and ligation of the adrenal veins. The venous drainage from each adrenal gland is usually via a single vein: the right vein draining into the inferior vena cava (IVC) and the left vein into the left renal vein. Although infrequent, variable venous drainage has been documented. The aim of the study was to clarify if LA identified venous drainage and its variants. Between January 1999 and January 2008, 142 consecutive patients underwent LA. Adrenal vein anatomy was documented on a prospective database. In total, 142 patients underwent 162 LA (right = 62, left = 66, bilateral = 17). All adrenal veins were identified at the time of laparoscopy. For 157 LA, the adrenal venous drainage was constant: right vein drained into the IVC and left vein drained into left renal vein. Five patients had adrenal vein variants: two right veins draining separately into IVC (n = 1), two right veins draining into the IVC and right renal vein (n = 1), and two left veins draining separately into the left renal vein (n = 3). Adrenal vein variants were present in patients with phaeochromocytomas (n = 4) or adrenocortical carcinoma (n = 1). The laparoscopic approach allowed an excellent view of the main adrenal venous anatomy. This has helped confirm the constant nature of the venous drainage and successfully identify variant adrenal veins. Clin. Anat. 21:660–665, 2008. © 2008 Wiley‐Liss, Inc.
Endoscopic anatomy of sphenoid sinus for pituitary surgery
Authors: Unlu A. , Meco C. , Ugur H.C. , Comert A. , Ozdemir M. , Elhan A.
Published: September 2008

Endoscopic endonasal transsphenoidal approach to the sellar region yields an alternative to classical microsurgical approaches. Endoscopes provide images that differ from microscopic view. This study aimed to highlight surgical landmarks and their anatomical relationships for pituitary surgery through endoscopic perspective. Ten sides of five adult cadaveric heads with red‐colored latex injected arteries were evaluated. Endoscopic dissections were performed and measurements were done in the sphenoid sinuses before and after the removal of bony structures in all the aspects. Endoscopic vision of the sellar region enabled a wide panoramic perspective and detailed inspection. The measurements, in general, indicated the variations in the bony structures and soft tissues. The width of the pituitary, which is the distance between the medial margins of the carotid prominences, was measured as 21 ± 2.5 mm and the distance between the medial margin of the carotid prominences at the lower margin of the pituitary was 18 ± 3.1 mm. After the bony structures were removed, further measurements were done. The width of the pituitary, which is the distance between the medial margins of the anterior curvature of the ICA, was measured as 23.2 ± 3 mm, while the distance between the posterior curvature of the ICA was 19.7 ± 4.9 mm. Endoscopic view provided superior detailed visualization of the close relationships between pituitary gland, internal carotid arteries, and optic nerves. This facilitated exact evaluation for variations, which could result in more effective and safe surgery. However, these variations again emphasize the necessity of preoperative radiological evaluation in each case. Clin. Anat. 21:627–632, 2008. © 2008 Wiley‐Liss, Inc.
Anatomical variations of the iliolumbar vein with application to the anterior retroperitoneal approach to the lumbar spine: A cadaver study
Authors: Unruh Kenneth P. , Camp Christopher L. , Zietlow Scott P. , Huddleston Paul M.
Published: September 2008

Objectives of this study include identification of lumbosacral venous variations, designation of a critical area of dissection for surgical exposure, and comparison between both male/female and right/left‐sided anatomy. Attempts were made to provide anatomic nomenclature that accurately describes these structures. Thirty‐eight iliolumbar venous systems in 20 cadavers (11 females/9 males) were dissected. Each system was identified as one of three patterns of variation: common venous trunk (combining ascending lumbar and iliolumbar venous systems) with distal veins, common venous trunk without distal veins, and venous systems without a common venous trunk. Dimensions including distances to the inferior vena cava (IVC) confluence, the obturator nerve, and the lumbosacral trunk, and venous stem length were obtained to aid surgical dissection. Differences between males and females and those between right and left sides were compared. Anterior lumbosacral venous variations could be organized into three groups. A Type 1 venous system (common venous trunk with distal veins) was most common (53% of systems). The anatomical name “lateral lumbosacral veins” adequately describes the anatomical location of these veins and does not assume a direction of venous flow or the lack of individual distal veins. A critical area bordered by the obturator nerve anteriorly, the psoas muscle laterally, the spinal column medially, and sacrum posteriorly within 8.2 cm of the IVC confluence should be defined to adequately dissect the lateral lumbosacral veins. Differences in male and female lateral lumbosacral venous anatomy do not alter surgeon's approach to the anterior lumbar spine. Clin. Anat. 21:666–673, 2008. © 2008 Wiley‐Liss, Inc.

Published: September 2008

Anatomic variations in the insertion of the long head of the biceps tendon and superior labral complex have been described (Erickson et al. [1992] AJR Am. J. Roentgenol. 158:1091–1096; Kreitner et al. [1998] AJR Am. J. Roentgenol. 170:599–605; Mariani et al. [1997] Arthroscopy 13:499–501; Vangsness Jr. et al. [1994] J. Bone Joint Surg. Br. 76:951–954). To the authors' knowledge, there have been only five reported cases of congenital absence of the long head of the biceps tendon. Three of these cases were associated with anterior shoulder instability, one with a superior labral anterior posterior lesion and one simply with shoulder pain. This is the first reported case of congenital absence of the biceps tendon associated with glenoid dysplasia and a posterior labral tear. Clin. Anat. 21:728–732, 2008. © 2008 Wiley‐Liss, Inc.

The increasing demands for new lead compounds in pharmaceutical and agrochemical industries have driven scientists to search for new bioactive natural products. Marine microorganisms are rich sources of novel, bioactive secondary metabolites, and have attracted much attention of chemists, pharmacologists, and molecular biologists. This mini‐review mainly focuses on macrolactins, a group of 24‐membered lactone marine natural products, aiming at giving an overview on their sources, structures, biological activities, as well as their potential medical applications.
The Production and Characterisation of Trichotoxin Peptaibols, by Trichoderma asperellum
Authors: Chutrakul Chanikul , Alcocer Marcos , Bailey Kevin , Peberdy John F.
Published: September 2008

Trichoderma spp. are regularly found as a constituent of the mycoflora of many soils and are noted for their antagonistic activity against bacteria and other fungi. This latter property is the basis for the widespread interest in their use in the biological control of soil‐borne fungal plant pathogens. This antagonism is partly based on their ability to produce an impressive inventory of secondary metabolites. An important group of bioactive metabolites produced by Trichoderma spp. are the non‐ribosomal peptides (NRPs), especially the peptaibols. A virulent antagonistic strain, T. asperellum, which had been used in biological control strategies in Malaysia and previously examined for mycolytic enzyme production, has been studied for its potential for peptaibol production. The present research demonstrated the ability of T. asperellum to produce at least two metabolites which were identified as acid trichotoxin 1704E (Ac‐Aib‐Gly‐Aib‐Leu‐Aib‐Gln‐Aib‐Aib‐Aib‐Ala‐Ala‐Aib‐Pro‐Leu‐Aib‐Iva‐Glu‐Vol) and neutral trichotoxin 1717A (Ac‐Aib‐Gly‐Aib‐Leu‐Aib‐Gln‐Aib‐Aib‐Aib‐Ala‐Aib‐Aib‐Pro‐Leu‐Aib‐Iva‐Gln‐Vol). Addition of free Aib to the culture medium enhanced the production of trichotoxins. Biological activity of these substances was investigated against Bacillus stearothermophilus. The general characteristics of peptaibols, also found in the trichotoxins, include the presence of high proportions of the uncommon amino acid Aib, the protection of the N‐ and C‐termini by an acetyl group and reduction of the C‐terminus to 2‐amino alcohols, respectively, amphipathy and microheterogeneity.

Published: September 2008

Bioassay‐guided fractionation of MeOH extract from fenugreek (Trigonella foenum‐graecum L.) seeds resulted in the isolation of two rat growth‐hormone release stimulators in vitro, fenugreek saponin I (1) and dioscin (9), along with two new, i.e., 2 and 3, and five known analogues, i.e., 4–8. The structures of the new steroidal saponins, fenugreek saponins I, II, and III (1–3, resp.), were determined as gitogenin 3‐O‐β‐D‐xylopyranosyl‐(1→6)‐β‐D‐glucopyranoside, sarsasapogenin 3‐O‐β‐D‐xylopyranosyl‐(1→6)‐β‐D‐glucopyranoside, and gitogenin 3‐O‐α‐L‐rhamnopyranosyl‐(1→2)‐β‐D‐glucopyranoside, respectively. Fenugreek saponin I (1) and dioscin (9) caused ca. 12.5‐ and 17.7‐fold stimulation of release, respectively, of rat growth hormone from rat pituitary cells, whereas gitogenin (5) showed moderate activity. To our knowledge, this is the first study to demonstrate that steroidal saponins stimulate rat growth‐hormone release in rat pituitary cells.

Authors: Remberg Barbara , Sterrantino Anna Freni , Artner Robert , Janitsch Christoph , Krenn Liselotte
Published: September 2008

Opium samples from Afghanistan were analyzed by HPLC for their content of morphine and three further alkaloids (codeine, thebaine, and papaverine). To our knowledge, this is the largest set of authentic opium samples analyzed in one study until now. The purpose was to assess possible correlations between samples and selected external factors, such as region of origin within Afghanistan, year of harvest, or intra‐batch variation. In the investigated samples, a trend towards higher morphine concentrations in opium from the North‐Eastern parts of Afghanistan was observed in the period from 2003 to 2005. More than 75% of the samples contained above 10% of morphine, the overall average was 14.4%.

Published: September 2008

Isolation, chemical characterization, and phytotoxicity of five new oxylipins, together with seven already known related compounds, from Cestrum parqui L' Hérl. is reported. All the structures were elucidated on the basis of their spectral data, especially 1D‐ (1H‐ and 13C‐NMR, DEPT) and 2D‐NMR (COSY, TOCSY, HSQC, HMBC, and NOESY). The configurations of the stereogenic C‐atoms were determined by the Mosher's method. The compounds have been assayed for their phytotoxicity on Lactuca sativa at concentrations ranging between 10−4 and 10−8 M. The results of the phytotoxicity tests on the germination and growth of the test species, obtained by a cluster analysis, showed interesting relationship between the chemical structures of the compounds and their biological effects.

Published: September 2008

The structures of two new cyathane‐type diterpenoids isolated from a liquid culture of Strobilurus tenacellus have been elucidated. The chemical structures of the new compounds 1 and 2 were identified as (12S)‐11α,14α‐epoxy‐13α,14β,15‐trihydroxycyath‐3‐ene and (12R)‐11α,14α‐epoxy‐13α,14β,15‐trihydroxycyath‐3‐ene, respectively, by spectral methods, including HR‐EI‐MS, and 1D‐ and 2D‐NMR techniques. Compounds 1 and 2 show antimicrobial activity against Pseudomonas aeruginosa. In addition, both compounds were also tested for activity against human cancer cells, and 2 showed growth inhibitory activity against YMB and COLO 201 cells.
X‐tended target projection (XTP)—comparison with orthogonal partial least squares (OPLS) and PLS post‐processing by similarity transformation (PLS + ST)
Authors: Kvalheim Olav M. , Rajalahti Tarja , Arneberg Reidar
Published: September 2008

Target projection (TP) also called target rotation (TR) was introduced to facilitate interpretation of latent‐variable regression models. Orthogonal partial least squares (OPLS) regression and PLS post‐processing by similarity transform (PLS + ST) represent two alternative algorithms for the same purpose. In addition, OPLS and PLS + ST provide components to explain systematic variation in X orthogonal to the response. We show, that for the same number of components, OPLS and PLS + ST provide score and loading vectors for the predictive latent variable that are the same as for TP except for a scaling factor. Furthermore, we show how the TP approach can be extended to become a hybrid of latent‐variable (LV) regression and exploratory LV analysis and thus embrace systematic variation in X unrelated to the response. Principal component analysis (PCA) of the residual variation after removal of the target component is here used to extract the orthogonal components, but X‐tended TP (XTP) permits other criteria for decomposition of the residual variation. If PCA is used for decomposing the orthogonal variation in XTP, the variance of the major orthogonal components obtained for OPLS and XTP is observed to be almost the same, showing the close relationship between the methods. The XTP approach is tested and compared with OPLS for a three‐component mixture analyzed by infrared spectroscopy and a multicomponent mixture measured by near infrared spectroscopy in a reactor.

Structures and Solvatochromic Phosphorescence of Dicationic Terpyridyl–Platinum(II) Complexes with Foldable Oligo(ortho‐phenyleneethynylene) Bridging Ligands
Authors: Zhu Ming‐Xin , Lu Wei , Zhu Nianyong , Che Chi‐Ming
Published: September 2008

A series of binuclear organoplatinum(II) complexes, [(tBu3tpy)Pt(CC1,2‐C6H4)nCCPt(tBu3tpy)][ClO4]2 (1–7, n=1, 2, 3, 4, 5, 6, 8; tBu3tpy=4,4′,4′′‐tri‐tert‐butyl‐2,2′:6′,2′′‐terpyridine) with foldable oligo(ortho‐phenyleneethynylene) linkers were prepared and characterized by spectroscopic methods and/or X‐ray crystallographic analyses. In the crystal structures of 3⋅2.5 CH3OH, 5⋅CH3CN, and 6⋅4 CH3CN, each of the bridging ortho‐phenyleneethynylene ligands has a partially folded conformation. In aerated water/acetonitrile mixtures with water percentages larger than 40 %, the emission of complexes 3–7 are red‐shifted and enhanced when compared to those recorded in acetonitrile. The red‐shift in emission energy and enhanced emission intensity can be attributed to the inter‐ and/or intramolecular interactions induced by the addition of water to solutions of the platinum(II) complexes in acetonitrile. Data from dynamic light scattering and transmission electron microscopy studies revealed that these binuclear platinum(II) complexes aggregated into nanosized particles in acetonitrile/water mixtures. Hydrophobic folding of the ortho‐phenyleneethynylene linkers in acetonitrile/water mixtures is postulated.
Protein Nanotubes Comprised of an Alternate Layer‐by‐Layer Assembly Using a Polycation as an Electrostatic Glue
Authors: Qu Xue , Lu Gang , Tsuchida Eishun , Komatsu Teruyuki
Published: September 2008

We present the synthesis and structure of various protein nanotubes comprised of an alternate layer‐by‐layer (LbL) assembly using a polycation as an electrostatic glue. The nanotubes were fabricated by sequential LbL depositions of positively charged polycations and negatively charged proteins into a porous polycarbonate (PC) membrane, followed by release of the cylindrical core by quick dissolution of the template with CH2Cl2. This procedure provides a variety of protein nanotubes without interlayer cross‐linking. The three‐cycle depositions of poly‐L‐arginine (PLA) and human serum albumin (HSA, Mw=66.5 kDa) into the porous PC template (pore diameter, Dp=400 nm) yielded well‐defined (PLA/HSA)3 nanotubes with an outer diameter of 419±29 nm and a wall thickness of 46±8 nm, revealed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) observations. The outer diameter of the tubules can be controlled by the pore size of the template (200–800 nm), whereas the wall thickness is always constant, independent of the Dp value. The (PEI/HSA)3 (PEI: polyethylenimine) nanotubes showed a slightly thin wall of 39±5 nm. CD spectra of the multilayered (PEI/HSA)n film on a flat quartz plate suggested that the secondary structure of HSA between the polycations was almost the same as that in aqueous solution. The three‐cycle LbL depositions of PLA and ferritin (Mw=460 kDa) or myoglobin (Mb, Mw=1.7 kDa) into the porous PC membrane also gave cylindrical hollow structures. The wall thickness of the (PLA/ferritin)3 and (PLA/Mb)3 nanotubes were 55±5 nm and 31±4 nm; it depends on the globular size of the protein (ferritin>HSA>Mb). The individual ferritin molecule was clearly seen in the tubular walls by SEM and TEM measurements.
Why Platinum Catalysts Involving Ligands with Large Bite Angle Are so Efficient in the Allylation of Amines: Design of a Highly Active Catalyst and Comprehensive Experimental and DFT Study
Authors: Mora Guilhem , Piechaczyk Olivier , Houdard Romaric , Mézailles Nicolas , Le Goff Xavier‐Frederic , le Floch Pascal
Published: September 2008

The platinum‐catalyzed allylation of amines with allyl alcohols was studied experimentally and theoretically. The complexes [Pt(η3‐allyl)(dppe)]OTf (2) and [Pt(η3‐allyl)(DPP‐Xantphos)]PF6 (5) were synthesized and structurally characterized, and their reactivity toward amines was explored. The bicyclic aminopropyl complex [Pt(CH2CH2CH2NHBn‐κ‐C,N)(dppe)]OTf (3) was obtained from the reaction of complex 2 with an excess of benzylamine, and this complex was shown to be a deactivated form of catalyst 2. On the other hand, reaction of complex 5 with benzylamine and allyl alcohol led to formation of the 16‐VE platinum(0) complex [Pt(η2‐C3H5OH)(DPP‐Xantphos)] (7), which was structurally characterized and appears to be a catalytic intermediate. A DFT study showed that the mechanism of the platinum‐catalyzed allylation of amines with allyl alcohols differs from the palladium‐catalyzed process, since it involves an associative ligand‐exchange step involving formation of a tetracoordinate 18‐VE complex. This DFT study also revealed that ligands with large bite angles disfavor the formation of platinum hydride complexes and therefore the formation of a bicyclic aminopropyl complex, which is a thermodynamic sink. Finally, a combination of 5 and a proton source was shown to efficiently catalyze the allylation of a broad variety of amines with allyl alcohols under mild conditions.
Mechanism of the Palladium‐Catalyzed Carbohydroxylation of Allene‐Substituted Conjugated Dienes: Rationalization of the Recently Observed Nucleophilic Attack by Water on a (π‐Allyl)palladium Intermediate
Authors: Karlsson Erik A. , Bäckvall Jan‐E.
Published: September 2008

The mechanism of the palladium‐catalyzed oxidative carbohydroxylation of allene‐substituted 1,3‐cyclohexadiene was studied by DFT calculations. All intermediates and transition states of the reaction were identified and their structures were calculated. The calculations confirm the mechanism previously proposed and show that the CC bond‐forming step occurs via insertion of one of the double bonds of 1,3‐cyclohexadiene into a Pdvinyl bond of a vinylpalladium intermediate. This reaction leads to a (π‐allyl)palladium intermediate, and coordination of benzoquinone and a double bond in the molecule to Pd creates a highly reactive cationic π‐allyl complex, which is readily attacked by water according to the calculations.
Origin of Diastereocontrol in the Oxy‐Michael Reactions of δ‐Lactol Anions: A Computational and Experimental Study
Authors: Richardson Robert D. , Hernandez‐Juan Felix A. , Ward John W. , Dixon Darren J.
Published: September 2008

The diastereoselectivity in the alkylation and Michael addition of “naked” 6‐substituted δ‐lactolates has been studied by density functional (B3LYP) calculations with ab initio (MP2) energy refinements. The resulting proposed model for the origins of stereocontrol in this reaction has been tested by experiment. The reactions lead to a high cis diastereoselectivity across the THP ring due to the preference for both the alkoxide and the 6‐substituent to sit equatorial in the alkylation transition structure. In the oxy‐Michael addition of these lactolates to β‐substituted nitroolefins, we propose that the high diastereoselectivity β‐ to the nitro group is a result of a combination of steric, stereoelectronic and solvation factors.
Sonochemical Synthesis under a Magnetic Field: Fabrication of Nickel and Cobalt Particles and Variation of Their Physical Properties
Authors: Abu‐Much Riam , Gedanken A.
Published: September 2008

We report on the variation of the physical properties of nickel and cobalt nanoparticles prepared by using ultrasound irradiation as energy source. First, we describe a sonochemical method for preparing aggregated particles. Second, we interpret the results on the basis of Einstein's theory (1905), which deals with a mathematical expression for the diffusivity of particles into solvents. This theory explains the stability of organosols of nickel and cobalt nanoparticles in polyethylene glycol. Finally, the effect of applying an external magnetic field during sonochemical formation of both aggregated particles and their stable colloids is investigated.

Effect of Overdischarge on Swelling and Recharge Performance of Lithium Ion Cells
Authors: LI Hui‐Fang , GAO Jun‐Kui , ZHANG Shao‐Li
Published: September 2008

Effects of overdischarge on characteristics of lithium ion cells were deeply studied, and experiments have been made to reveal its mechanisms. The results suggest that overdischarge may result in large swelling of cells and degradation of recharge capabilities. The mechanism can be explained as that: a copper foil used as an anode collector will be oxidized to copper ion when deep overdischarge occurs and reduce at the anode in recharging progress, which greatly deteriorates the cell efficiency; solid electrolyte interface (SEI) film is to decompose and reform because of excessive de‐intercalation of lithium ions, and the released gas such as carbon dioxide makes the cell bulge. The experimental results prove that when 20% Li(Ni1/3Co1/3Mn1/3)O2 was added to LiCoO2 cathode materials, the cell swelling rate could be greatly reduced, and the recharge capability would be enhanced much.
Immobilized Palladium on Organic‐inorganic Hybrid Materials: A Novel and Reusable Catalyst for the Copper‐Free Sonogashira Coupling Reaction
Authors: ZHANG Li‐Yuan , WANG Lei
Published: September 2008

The immobilized palladium on organic‐inorganic hybrid materials catalyzing the copper‐free Sonogashira coupling reaction has been described. Terminal alkynes were reacted with aryl iodides and aryl bromides in the presence of 3‐[N,N‐bis(diphenylphosphino)amino]propyl functionalized silica gel immobilized palladium catalyst. The protocol involved the use of ethylene glycol as a solvent, and triethylamine as a base. The reactions generated the corresponding cross‐coupling products in excellent yields. Furthermore, the silica‐supported phosphine palladium complexes and ethylene glycol could be recovered and recycled for six consecutive trials without significant loss of their activity.
