Strong resistance of (tridecafluoro‐1,1,2,2‐tetrahydrooctyl)triethoxysilane (TTS) nanofilm to protein adsorption
Authors: Alluri Chandrakanth , Ji Hai‐Feng , Sit PingFai Sidney 
Published: July 2013

AbstractIn this report, the properties of fluorocarbon‐containing (tridecafluoro‐1,1,2,2‐tetrahydrooctyl)triethoxysilane (TTS) (C14H19F13O3Si) nanofilm coated on silicon surface and its potential to resist protein adsorption were examined. Thickness and wettability of the silicon surface before and after TTS nanofilm coating were examined by ellipsometry and contact angle goniometry, respectively. The same techniques were used to examine protein layer on nonmodified and TTS‐coated silicon surface. In addition, bright‐field optical microscopy and fluorescence spectrophotometry were used to provide visual, qualitative description of adsorbed proteins and the specific signal of fluorescence‐labeled bovine serum albumin (BSA), respectively, on bare and TTS‐coated silicon surface. Single‐component protein solution of four model proteins, namely BSA, human fibrinogen, bovine serum immunoglobulin G, and fibronectin, was prepared, and the adsorption responses of these four proteins on TTS nanofilm were examined, using nonmodified silicon surface as comparison. TTS substantially reduces the adsorption of all four proteins tested. Our results indicate that fluorocarbon‐containing TTS, once coated on surfaces, is an effective molecule for resisting protein adsorption. This will open up potential applications, particularly for silicon‐containing implant devices such as glass.

Published: July 2013

AbstractAn amylase‐producing psychrotroph bacterium was isolated from soil and identified as belonging to the genus Exiguobacterium. A novel cold‐adapted α‐amylase, Amy SH3, was purified from culture medium of this bacterium using acetone precipitation and DEAE‐Sepharose anion‐exchange chromatography. The molecular mass of the enzyme was estimated about 34 kDa using SDS‐PAGE. Biochemical characterization of Amy SH3 revealed that the optimum temperature for maximum activity of Amy SH3 was 37°C. However, Amy SH3 was also active at cold temperatures, showing 13% and 39% activity at 0 and 10°C, respectively. The optimum pH for maximum activity of Amy SH3 was pH 7, whereas the amylase was active over a pH range of 5 to 10. The activity of Amy SH3 was enhanced by Co2+ but decreased by Mg2+, Mn2+, Zn2+, Fe2+, and Ca2+. Amy SH3 was able to retain 76% of its activity in the presence of 0.5% SDS. The Km and Vmax of the enzyme were calculated to be 0.06 mg/mL and 4,010 U/mL, respectively. The cold‐adapted Amy SH3 seems very promising for applications at ambient temperature.

AbstractEvaporation rates play a key role in evaporation crystallization and the drying of crystal products. Raman analysis was used to study the effect of the evaporation rate on the polymorphs of indomethacin at room temperature. The studied solvents were highly volatile ethanol, acetone, and ethyl acetate. The approach was based on a mass transfer model of evaporation, and experimental flux measurements were used for model evaluation. Evaporation rates from porous carriers were also investigated. The studied mesoporous silicon microparticles can be used in oral dosage forms of poorly soluble active pharmaceutical ingredients. Evaporation rates of dimethyl sulfoxide from a pure solvent, from indomethacin solutions, and from solutions containing microparticles were measured at 100 °C. An evaporation rate model of porous particles was used and the predicted results were compared with the experimental results obtained.

Published: July 2013

AbstractThe ruthenium‐catalyzed hydroformylation of 1‐ and 2‐octene to give preferentially the corresponding linear aldehyde is reported. The catalyst system comprising of Ru3(CO)12 and an imidazole‐substituted monophosphine ligand allows for high chemo‐ and regioselectivity. The hydroformylation proceeds with unprecedented rates for a ruthenium‐based catalyst.
Stereocomplementary Routes to Hydroxylated Nitrogen Heterocycles: Total Syntheses of Casuarine, Australine, and 7‐epi‐Australine
Authors: Parmeggiani Camilla , Cardona Francesca , Giusti Leonardo , Reissig Hans‐Ulrich , Goti Andrea 
Published: July 2013

AbstractAddition of lithiated 1‐benzyloxyallene to a D‐arabinose‐derived cyclic nitrone occurred with perfect diastereoselectivity furnishing a bicyclic 1,2‐oxazine derivative, which is an excellent precursor for pyrrolizidine alkaloids hydroxylated at C‐7 with optional configuration at this stereogenic center. Depending on the stage of the NO bond cleavage and ring re‐closure, 7‐hydroxypyrrolizidines with 7R or 7S configuration were obtained, as a result of completely selective addition reactions occurring complementarily at the bottom or top face of the endocyclic CC double bond in six‐ and five‐membered B rings, respectively. Applicability of these stereodivergent routes to obtain polyhydroxy pyrrolizidine alkaloids is demonstrated by the efficient syntheses of casuarine and australine as examples of the two classes of diversely configured 7‐hydroxypyrrolizidine alkaloids. An alternative synthesis of australine and two strategies for the preparation of 7‐epi‐australine are also reported, which demonstrate that the stereoselectivity of hydride reduction of an exocyclic CO double bond is independent of the ring size, occurring preferentially from the top face either in a six‐ or five‐membered ring.
