Hydrogen desorption properties of Li-N-H system (composed of LiH + LiNH2) doped with LiBH4 as catalyst and microwave absorber have been investigated under microwave irradiation. The results showed that pure Li-N-H system can not be heated effectively by microwave irradiation, but it can be rapidly heated up to 500 degrees C within 5 min with 7.6 wt.% LiBH4 addition by a microwave heating with a power of 400 W. Further study indicates that it is Li4BN3H10 generated during the ball milling process that acts as the microwave absorber and catalyst. Li-N-H +7.6 wt% LiBH4 by microwave heating desorbed 4.95 wt.% hydrogen which is 3.6 times more than that of Li-N-H +7.6 wt.% graphite by electric resistance heating at 250 degrees C within 30 min, indicating that the desorption kinetics of Li-N-H system is improved by the combination of the catalytic effect of Li4BN3H10 and microwave irradiation. Furthermore, the isothermal kinetics of Li-N-H with 7.6 wt.% LiBH4 under microwave irradiation were well fitted by Johnson-Mehl-Avrami-Kolmogorov (JMAK) model and the activation energy was 43.9 kJ/mol H-2 which is significantly lower than that under electric resistance heating, demonstrating that the desorption kinetics of Li-N-H with LiBH4 addition could be effectively improved by microwave irradiation.

Two methods were compared to convert ferrocene into N,N-diisopropylferrocenecarboxamide, N,N-diethylferrocenecarboxamide, N,N-dimethylferrocenecarboxamide, and (4-morphohnocarbonyl)ferrocene, namely, deprotometalation followed by trapping using dialkylcarbamoyl chlorides and amide formation from the intermediate carboxylic acid. The four ferrocene-carboxamides were functionalized at C-2; in the case of the less hindered and more sensitive amides, recourse to a mixed lithium-zinc 2,2,6,6-tetramethylpiperidino-based base allowed us to achieve the reactions. Halogen migration using lithium amides was next optimized. Whereas it appeared impossible to isolate the less hindered 3-iodoferrocenecarboxamides, 3-iodo-N,N-diisopropylferrocenecarboxamide proved stable and was converted to new 1,3-disubstituted ferrocenes by Suzuki coupling or amide reduction. DFT calculations were used to rationalize the results obtained.

The development of a greener allylation reagent for alpha-allylation of carbonyl compounds is of great necessity. Here we present allyltrimethylsilane as a novel allylation reagent in the photoredox-catalyzed alpha-allylation of carbonyl compounds such as ketones, esters, and amides. The reaction process shows good functional group tolerance and generates a good yield of the product. The reaction mechanism is a radical-mediated reaction by photo-induced single electron transfer.

A porous silicon rugate filter (pSiRF) insulin biosensor has been constructed and systematically optimised by investigating the effects of specific experimental parameters. The pSiRF biosensor is based on an optical sensing platform using interferometric reflectance spectroscopy (IRS) to monitor insulin binding to a surface-anchored insulin binding aptamer (IBA) within the pores. The aim of this study was to determine the optimal fabrication to elicit the maximum sensor response, lowest limit of detection (LOD) and fastest response time. Thermal hydrosilylation with undecylenic acid was used as a base surface modification, with IBA attached through formation of an amide bond. The following pSiRF fabrication conditions were investigated; porous film thickness and IBA concentration in the conjugation solution. The effect of solution flow speed over the pSiRF during insulin biosensing was also investigated in an effort to improve the performance. The optimised pSiRF biosensor was successfully applied for the detection of insulin secreted from human islets on stimulation with glucose. Finally, as a proof of concept, insulin sensing in the presence of human islets on the pSiRF surface was performed to demonstrate the robust performance of the biosensor and the potential for in-situ insulin biosensing.

Alginate is an abundant natural polysaccharide widely utilized in various biomedical applications. Alginate also possesses numerous hydroxyl and carboxylate functional groups that allow chemical modifications to introduce different functionalities. However, it is difficult to apply various chemical reactions to alginate due to limited solubility in organic solvents. Herein, functional moieties for radical polymerization and cell adhesion were separately conjugated to hydroxyl and carboxylate groups of alginate, respectively, in order to independently control the crosslinking density and cell adhesive properties of hydrogels. Sodium counterions of alginate are first substituted with tetrabutylammonium ions to facilitate the dissolution in an organic solvent, followed by in situ conjugations of (1) cell adhesion molecules (CAM) via carbodiimide-mediated amide formation and (2) methacrylate via ring-opening nucleophilic reaction. The resulting CAM-linked methacrylic alginate was able to not only crosslink different monomers to form hydrogels with varying mechanical properties, but also induce stable cell adhesion to the hydrogels.

Colchicine is the major alkaloid isolated from the plant Colchicum autumnale, which shows strong therapeutic effects towards different types of cancer. However, due to the toxicity of colchicine towards normal cells its application is limited. To address this issue we synthesized a series of seven triple-modified 4-bromothiocolchicine analogues with amide moieties. These novel derivatives were active in the nanomolar range against several different cancer cell lines and primary acute lymphoblastic leukemia cells, specifically compounds: 5-9 against primary ALL-5 (IC50 = 5.3-14 nM), 5, 7-9 against A549 (IC50 = 10 nM), 5, 7-9 against MCF-7 (IC50 = 11 nM), 5-9 against LoVo (IC50 = 7-12 nM), and 5, 7-9 against LoVo/DX (IC50 = 48-87 nM). These IC50 values were lower than those obtained for unmodified colchicine and common anticancer drugs such as doxorubicin and cisplatin. Further studies revealed that colchicine and selected analogues induced characteristics of apoptotic cell death but manifested their effects in different phases of the cell cycle in MCF-7 versus ALL-5 cells. Specifically, while colchicine and the studied derivatives arrested MCF-7 cells in mitosis, very little mitotically arrested ALL-5 cells were observed, suggesting effects were manifest instead in interphase. We also developed an in silico model of the mode of binding of these compounds to their primary target, beta-tubulin. We conducted a correlation analysis (linear regression) between the calculated binding energies of colchicine derivatives and their anti-proliferative activity, and determined that the obtained correlation coefficients strongly depend on the type of cells used.

The apparent molar volumes of tetramethylurea (TMU) in the mixture of N,N-dimethylformamide (DMF) and water (W) have been determined within the temperature range: T = (293.15-308.15) K from density measurements. Based on Redlich-Meyer equation partial molar volumes and by coefficient describing the character of interactions were calculated. The results obtained for TMU showing hydrophobic properties have been compared with the corresponding results for urea that shows hydrophilic properties. This allowed us to analyze the solvation process of the investigated substances as well as to show an opposite behavior of urea in relation to TMU in the mixture DMF+W, particularly in the area of high water content.

Solvent exchange rates provide important information about the structural and dynamical properties of biomolecules. A large number of NMR experiments have been developed to measure such rates in proteins, the great majority of which quantify the buildup of signals from backbone amides after initial perturbation of water magnetization. Here we present a different approach that circumvents the main limitations that result from these classical hydrogen exchange NMR experiments Building on recent developments that enable rapid recording of chemical exchange saturation transfer (LEST) pseudo-3D data sets, we describe a N-15-based CEST scheme for measurement of solvent exchange in proteins that exploits the one-bond N-15 deuterium isotope shift. The utility of the approach is verified with an application to a 236 residue intrinsically disordered protein domain under conditions where it phase separates and a second application involving a mutated form of the domain that does not phase separate, establishing very similar hydrogen exchange rates for both samples. The methodology is well suited for studies of hydrogen exchange in any N-15-labeled biomolecule. A discussion of the merits of the CEST experiment in relation to the popular CLEANEX-PM scheme is presented.

The gold(I)-catalysed cyclization of N-tosyl-protected 5-benzyl-6-((trimethylsilyl)ethynyl)-1,2,3,4-tetrahydropyridines, prepared by the Sonogashira coupling of lactam-derived enol triflates, provides tetrahydrobenzo[g]quinolines whose skeleton represents a recurrent motif in natural compounds. The Au(I)-catalysed reaction is carried out with (C6F5)(3)PAuCl/AgNTf2 as the catalyst system and proceeds via a 6-exo-dig cyclization to form an exocyclic double bond, which eventually isomerises to the aromatic tetrahydrobenzo[g]quinoline. The mode of cyclization is discussed and supported by DFT calculations.
