The Imino Stannylene SnNH Incorporated in a Molecular Tin-Nitrogen Cage and other Tin(II)-Nitrogen Derivatives

The iminostannylene HNSn was successfully incorporated in a molecular cage of composition (Me2RSi-NSn)(3)(HNSn) with group R either being a methyl (1) or vinyl (2) substituent. An X-ray structure analysis reveals that 2 consists of a distorted Sn4N4 cube. The Sn-N(H) bond lengths [2.189(2) angstrom] are in the range for Sn4N4 hetero cubanes. When stored in a toluene solution the clusters 1 and 2 decompose slowly into the symmetric cubanes (Me2RSi-NSn)(4) [R = Me (3), CHCH2 (4)] and an amorphous and insoluble powder of composition HNSn. The decomposition follows a first order rate law as established for 2 with a half life time t(1/2) = 320 d at 20 degrees C. The compounds 1 and 2 can thus be regarded as a result of interaction between three entities {Me2RSi-NSn} and one entity {HNSn}. We also isolated the twistane-like Me2Si(NtBu)(2)Sn(2)NtBu (5) in a crystalline form. The central structure of this molecule, which has almost C-2v symmetry, has a trigonal bipyramid Sn2N3 unit with the nitrogen atoms occupying the equatorial plane. Each nitrogen atom has a tert-butyl ligand and two of the N atoms are further connected by the dimethylsilyl group. There is one nitrogen atom in an almost planar environment (only bonding to tert-butyl and two tin atoms) with a remarkable short Sn-N bond length of 2.048(5) angstrom. Both tin atoms in cage 5 can bond to Cr(CO)(5) to form [Me2Si(NtBu)(2)Sn(2)NtBu][Cr(CO)(5)](2) (6) with an almost linear Cr-Sn center dot center dot center dot Sn-Cr arrangement and Sn-Cr bond lengths of 2.581(1) angstrom (X-ray diffraction).

Intermolecular interaction in the hybrid gel of scallop (Patinopecten yessoensis) male gonad hydrolysates and kappa-carrageenan

Various bond disrupting agents including NaCl, GuHCl, urea, and SDS were introduced to investigate the intermolecular interactions between scallop (Patinopecten yessoensis) male gonad hydrolysates (SMGHs) and kappa-carrageenan (kappa-C), which were monitored by changes in rheological property, water distribution, conformation characterization and microstructure by using rheometer, low field-NMR relaxometry, Fourier transform infrared (FTIR) spectroscopy, cryo-scanning electron microscopy (cryo-SEM), and confocal laser scanning microscopy. The results showed that the bond disrupting agents deteriorated the rheological property of SMGHs/kappa-C in a dose-dependent manner. Indeed, at the same concentration of 2 M, NaCl deteriorated the SMGHs/kappa-C more obviously than GuHCl and urea. In addition, SMGHs/kappa-C with bond disrupting agents possessed higher relaxation times including T-21 and T-23, indicating the migration to free water direction of bound and free water. Moreover, the FITR results showed the red-shift in water regions (amide A and B bands), amide I and II bands, and indicated the breakdown of hydrogen bonds and electrostatic interactions, indicating a disordered structure in SMGHs/kappa-C by various bond disrupting agents. Furthermore, cryo-SEM results showed the change of SMGHs/kappa-C from a homogeneous network to a looser and ruptured one with larger void spaces, and indicated the disrupted and tattered microstructure of SMGHs/kappa-C by various bond disrupting agents. Additionally, SMGHs/kappa-C as well showed less aggregates stained by RITC by bond disrupting agents. These results suggest that electrostatic interactions would be mainly involved in the maintenance of SMGHs/kappa-C gel network. This study could provide theoretical and methodological basis for hydrogel products with modified gel strength and microstructure by understanding the intermolecular interactions in gel system. Practical Application Scallop (Patinopecten yessoensis) male gonads as a high-protein part of scallop, is usually discarded during processing despite its edibility. In recent years, scallop male gonads are regarded as good sources to develop protein matrices due to their high protein content and numerous nutrients. In this study, scallop male gonad hydrolysates (SMGHs) were obtained by trypsin-treated process. The considerable gelation behavior of SMGHs indicated that the SMGHs could be potentially utilized as a novel thickener and additive in production of kamaboko gels, can, sausage and spread with marine flavor.

Catechol-modified poly(oxazoline)s with tunable degradability facilitate cell invasion and lateral cartilage integration

Tissue adhesives play an important role in clinical applications and may aid in the treatment of cartilage defects for improved cartilage integration. However, many fail to satisfy the demand for adequate adhesive strength on wet tissue surfaces and to facilitate sufficient cell migration and extracellular matrix (ECM) deposition at the defect site. Utilizing poly(2-alkyl-2-oxazoline) (POx)-based polymers equipped with mussel-inspired adhesion moieties and combining them with the natural wound sealant fibrinogen, we fabricated an adhesive biosynthethic hydrogel with tunable mechanical properties and improved bonding strength. Degradation of the hydrogels could be adjusted by the ratio of amide to ester linkages of the catecholic functional group at the POx side chain. In an in vitro disc/ring model for lateral cartilage integration, a benefit in long-term integration was observed with enhanced degradation of the adhesive without the expense of bonding strength. Incorporation of degradable ester linkages in the polymer facilitated cell invasion and strong deposition of cartilaginous ECM at the defect site. Overall, the results suggest that the presented injectable adhesive hydrogel, due to its easy tunability, holds great potential for cartilage defect treatment and other medical applications.

Dual Interphase Layers In Situ Formed on a Manganese-Based Oxide Cathode Enable Stable Potassium Storage

Mn-based oxides have attracted extensive attention as electrode materials. However, the irreversible phase transition and Mn2+ dissolution result in their structure instability and performance decay. Here, we report dual interphase layers in situ formed on P2-K0.67MnO2 (P2-KMO) in 6.0 M of potassium bis(fluorosulfonyl)amide in diglyme (KFSI/G2) during charging. It is composed of a solid-electrolyte interphase (SEI) and K-poor spinel interlayer on P2-KMO, which are derived from the simultaneous decomposition of 6.0 M KFSI/G2 and disproportionation of surface Mn3+ They cooperatively enable the reversible phase transition of P2 <-> P ” 2 in the bulk P2-KMO and mitigate Mn loss. This leads to a high capacity retention of 90.5% and a Coulombic efficiency of 100% after 300 cycles. The investigation highlights the significance of interphase chemistry of electrode materials for potassium-ion batteries and beyond.

Improvement of 3D printability of buckwheat starch-pectin system via synergistic Ca2+-microwave pretreatment

Synergistic calcium chloride and microwave heating treatment was applied to improve the rheological properties and printability of a model buckwheat starch-high-methoxy pectin (BP) gel system. Rheological property results suggested that sole microwave heating significantly improved the plasticity, while synergetic treatment significantly decreased the viscosity of the gel. Microwave heating weakened the hydrogen bonding within the gel. On the other hand, synergistic treatment caused an aggregation through cross-linkage between Ca2+ and amide group within the gel; this in turn resulted in the discharge of part of water bound to gel matrix and hence the lower viscosity of the gel. Printing experiments revealed that synergistic pretreatment for 30 s could significantly improve the printing precision of the gel when compared with that of the gel sample steamed for 30 min.

Mesoporous zirconia nanoparticles as drug delivery systems: Drug loading, stability and release

Drug delivery systems have been a milestone in medical research in the last twenty years, still representing a key aspect of innovation and evolution in pharmacokinetics and pharmacodynamics. Among several proposed solutions, inorganic mesoporous materials could be a promising vehicle. Their specific chemical-physical properties make them ideal candidates for the adsorption and loading of active pharmaceutical ingredients (API). Recently, mesoporous zirconia nanoparticles (MZNs) have been described as a novel drug delivery system due to their high surface area and biocompatibility. In this work, we investigated the loading and release efficiencies of a wide range of API on MZNs characterized by suitable pore volume and versatility, focusing on the integrity of the released drugs investigated through solution NMR and E SI-MS techniques. In order to explore the potentialities of MZNs for biomedical applications, we selected ibuprofen, N-acetyl-L-cysteine, vancomycin, gentamicin, nitrofurantoin, and indomethacin as benchmark API characterized by a wide range of polarity, molecular weight and presence of different functional groups. MZNs showed to efficiently load and release most of the API investigated. Long time loadings were also investigated observing that, after more than three months, no side reaction occurred on the released drugs except for intrinsically more labile API like NTF and NAC. MZNs ensured high inertness towards a wide range of functional groups such as aliphatic and aromatic amides, acetals of sugar residues as well as several chiral moieties bearing tertiary stereocenters.

Ruthenium(IV) Intermediates in C-H Activation/Annulation by Weak O-Coordination

Ruthenium(IV) complexes were identified as key intermediates of C-H/O-H activations by weak O-coordination. Thus, the annulations of sulfoxonium ylides by benzoic acids provided expedient access to diversely-decorated isocoumarins with ample scope. Detailed experimental and computational studies provided strong support for a facile BIES-C-H activation, along with cyclometalated ruthenium(IV) intermediates within a versatile ruthenium(II/IV) catalysis regime (BIES=base-assisted internal electrophilic substitution).

Raman spectral imaging of (CHN)-C-13-H-2-N-15-labeled a-synuclein amyloid fibrils in cells

Parkinson’s disease is characterized by the intracellular accumulation of alpha-synuclein (alpha-syn) amyloid fibrils, which are insoluble, beta-sheet-rich protein aggregates. Raman spectroscopy is a powerful technique that reports on intrinsic molecular vibrations such as the coupled vibrational modes of the polypeptide backbone, yielding secondary structural information. However, in order to apply this method in cells, spectroscopically unique frequencies are necessary to resolve proteins of interest from the cellular proteome. Here, we report the use of (CHN)-C-13-H-2-N-15-labeled alpha-syn to study the localization of preformed fibrils fed to cells. Isotopic labeling shifts the amide-I (C-13=O) band away from endogenous C-12=O vibrations, permitting secondary structural analysis of internalized alpha-syn fibrils. Similarly, C-13-H-2 stretches move to lower energies in the cellular quiet region, where there is negligible biological spectral interference. This combination of well-resolved, distinct vibrations allows Raman spectral imaging of a-syn fibrils across a cell, which provides conformational information with spatial context.

Asymmetric Synthesis of Pyrrolizidines, Indolizidines and Quinolizidines via a Double Reductive Cyclisation Protocol

This account describes an overview of the asymmetric syntheses of pyrrolizidines, indolizidines and quinolizidines via a common double reductive cyclisation protocol. The highly diastereoselective conjugate addition of an enantiopure lithium amide to an ,-unsaturated ester incorporating a terminal C=C bond installed the nitrogen-bearing stereogenic centre and was followed by enolate functionalisation to introduce the second olefinic functionality. Alternatively, conjugate addition to the corresponding -alkenyl ,-unsaturated ester followed by -protonation of the intermediate enolate may also be used to access the cyclisation precursor. After oxidation of the two terminal olefinic units to give the corresponding dialdehyde, tandem hydrogenolysis/hydrogenation was employed to efficiently construct the azabicyclic core of each target molecule. This double reductive cyclisation strategy was successfully utilised in the syntheses of 13 azabicyclic alkaloids or closely related analogues. 1 Introduction 2 Asymmetric Syntheses of (-)-Isoretronecanol and (-)-Trachelanthamidine 3 Asymmetric Syntheses of (+)-Trachelanthamidine [(+)-Laburnine], (+)-Tashiromine and (+)- epi -Lupinine 4 Asymmetric Syntheses of (-)-Hastanecine, (-)-Turneforcidine and (-)-Platynecine 5 Asymmetric Syntheses of (-)-Macronecine, (-)-Petasinecine, (-)-1- epi -Macronecine, (+)-1- epi -Petasinecine and (+)-2- epi -Rosmarinecine 6 Conclusion
