Hunt, Andrew P.;Batka, Allison E.;Hosseinzadeh, Marjan;Gregory, Jordan D.;Haque, Halima K.;Ren, Hang;Meyerhoff, Mark E.;Lehnert, Nicolai research published ã€?Nitric Oxide Generation on Demand for Biomedical Applications via Electrocatalytic Nitrite Reduction by Copper BMPA- and BEPA-Carboxylate Complexesã€? the research content is summarized as follows. Intravascular (IV) catheters are essential devices in the hospital that are used to monitor a patient’s blood and for administering drugs or nutrients. However, IV catheters are also prone to blood clotting at the point of insertion and infection by formation of robust bacterial biofilms on their surface. Nitric oxide (NO) is ideally suited to counteract both of these problems, due to its antimicrobial properties and its ability to inhibit platelet activation/aggregation. One way to equip catheters with NO releasing properties is by electrocatalytic nitrite reduction to NO by copper complexes in a multi-lumen configuration. In this work, we systematically investigate six closely related Cu(II) BMPA- and BEPA-carboxylate complexes (BMPA = bis-(2-methylpyridyl)amine; BEPA = bis-(2-ethylpyridyl)amine), using carboxylate groups of different chain lengths. The corresponding Cu(II) complexes were characterized using UV-Vis, EPR spectroscopy, and X-ray crystallog. Using detailed cyclic voltammetry (CV) and bulk electrocatalyic studies (with real-time NO quantification), in aqueous buffer, pH 7.4, we are able to derive clear reactivity relations between the ligand structures of the complexes, their Faradaic efficiencies for NO generation, their turnover frequencies (TOFs), and their redox potentials. Our results show that the complex [Cu(BEPA-Bu)](OAc) is the best catalyst with a high Faradaic efficiency over large nitrite concentration ranges and the expected best tolerance to oxygen levels. For this species, the more pos. redox potential suppresses NO disproportionation, which is a major Achilles heel of the (faster) catalysts with the more neg. reduction potentials.

Hussaini, Sunusi Y.;Haque, Rosenani A.;Haziz, Umie F. M.;Amirul, A. A.;Razali, Mohd. R. research published ã€?Dinuclear silver(I)- and gold(I)-N-heterocyclic carbene complexes of N-alkyl substituted bis-benzimidazol-2-ylidenes with aliphatic spacer: Synthesis, characterizations and antibacterial studiesã€? the research content is summarized as follows. New series of dinuclear Ag(I)-NHC and Au(I)-NHC complexes (NHC = N-heterocyclic carbene) bearing n-alkyl homologous series with propylene spacers were synthesized. Initially, bis-benzimidazolium salts, 1–5 were synthesized via two steps n-alkylation reaction. The salts were then subsequently deprotonated with basic metal source (Ag₂O) using in-situ deprotonation method to obtain the Ag(I)-NHC complexes 6–10, resp. The Au(I)-NHC complexes, 11–15 were synthesized via transmetalation reaction from their resp. Ag(I)-NHC complexes. All compounds were fully characterized by elemental analyses, FT-IR, ¹H and ¹³CNMR spectroscopy. The antibacterial studies of these compounds were evaluated against E. coli and S. aureus using disk diffusion method. The Ag(I)-NHC complexes exhibit better activities with inhibition zone of 11 ± 1-20 ± 1mm and 9 ± 0-16 ± 1mm against E. coli and S. aureus resp., while Au(I)-NHC complexes show inhibition zone of 7 ± 0-14 ± 1mm for both E. coli and S. aureus bacteria. All the resp. benzimidazolium salts were inactive against the bacterial strains. Herein, authors found that the antibacterial activity is enhanced by the degree of bond strength due to the match between the hardness and softness of the metal center (Lewis acid) and NHC moiety (Lewis base). In this point of view, the Ag(I)-C bond was stronger bond to NHC ligand (hard acid-hard base combination) than that of Au(I)-C (soft acid-hard base combination) which resulted the slow release of silver ions for better activity. This is due to the fact that the antibacterial activities of complexes are related with delaying in releasing the metal ions (Ag⁺ and Au⁺) into the cell membrane.

Hwang, Nicky;Sun, Liren;Noe, Daisy;Lam, Patrick Y. S.;Zhou, Tianlun;Block, Timothy M.;Du, Yanming research published ã€?Hepatoselective Dihydroquinolizinone Bis-acids for HBsAg mRNA Degradationã€? the research content is summarized as follows. Chronic hepatitis B (CHB) is characterized by high levels of hepatitis B virus (HBV) surface antigen (HBsAg) in blood circulation. A major goal of CHB interventions is reducing or eliminating this antigenemia; however, there are currently no approved methods that can do this. A novel family of compounds with a dihydroquinolizinone (DHQ) scaffold has been shown to reduce circulating levels of HBsAg in animals, representing a first for a small mol. Reductions of HBsAg were a result of the compound’s effect on HBsAg mRNA levels. However, com. development by Roche of a DHQ lead compound, RG-7834, was stopped due to undisclosed toxicity issues. Herein we report our effort to convert the systemic RG7834 compound to a hepatoselective DHQ analog to limit its distribution to the bloodstream and thus to other body tissues.

A new concept of utilization of particle-polymer hybrids as multifunctional additives for polymer blends was introduced in this study. Graphene oxide particles with short densely grafted polystyrene brushes (GO-g-PS) were prepared by surface-initiated atom transfer radical polymerization (SI-ATRP). Melt rheol. studies revealed that GO-g-PS suppressed the phase separation of miscible poly(Me methacrylate)/poly(styrene-co-acrylonitrile) (PMMA/SAN) blends. The studies suggested specific interactions of GO-g-PS with the PMMA phase and this was confirmed based on calculations of activation energies of segmental relaxations by broadband dielec. spectroscopy (BDS). These unusual interactions of GO-g-PS with PMMA phase were assigned to the specific and precise architecture of the GO-g-PS particles as well as chem. nature of PS polymer brushes. The short chains of PMMA and PS provide miscibility originating from UCST behavior of PMMA/PS blend of short polymer chains. Addnl., BDS also revealed improved charge transport in PMMA/SAN blend in presence of GO-g-PS hybrid.

Hu, Chaolei;Xu, Wenjing;Conrads, Christian Martin;Wu, Jingnan;Pich, Andrij research published �Visible light and temperature dual-responsive microgels by crosslinking of spiropyran modified prepolymers� the research content is summarized as follows. Light-responsive microgels are interesting colloidal systems with potential applications in the biotechnol. and medicine. However, synthesis of light-responsive microgels with high loading of photoswitchable mols. is still very challenging. Herein we developed a new method to synthesize light and temperature dual-responsive spiropyran-modified poly(N-vinylcaprolactam) microgels. The novel and straightforward microgels synthesis route involved: a) synthesis of poly(N-vinylcaprolactam-co-vinylformamide) copolymers via RAFT polymerization followed by the hydrolysis to obtain primary amine groups, b) attachment of carboxyl-modified spiropyran mols. to polymer chains via coupling, and c) crosslinking of spiropyran-modified polymer chains in W/O miniemulsion to form microgels. Via this method, we successfully synthesized poly(N-vinylcaprolactam) microgels containing more than 10 mol% spiropyran. The reversible light responsiveness of the spiropyran-modified copolymers and microgels in aqueous solution, which originates from the spiropyran photoisomerization under irradiation with different wavelengths, was demonstrated by UV-Vis spectroscopy. Spiropyran-modified copolymers demonstrate shift of the lower critical solution temperature (LCST) due to the polarity change of spiropyran mols. under dark, UV and visible light. Surprisingly, dynamic light scattering (DLS) results show that the microgels based on the same copolymers are less affected by UV irradiation Microgels are swollen in darkness when spiropyran mols. are in the polar, merocyanine form, and collapse after irradiation with visible light, due to the transformation of spiropyran to the relatively nonpolar, closed spirocyclic form. In addition, the spiropyran-modified microgels exhibit reversible temperature responsiveness by presenting a volume phase transition in water from a swollen state to a collapsed state with increasing temperature and the transition temperature decreased compared to the pristine microgels due to the hydrophobicity of spiropyran units.

In this study, we synthesized and characterised two benzimidazole-quinoline-based copper complexes, namely, [Cu(btmbq)Br]2 (1) and [Cu(btmbq)Cl]2 (2), (btmbq = 3-(1-(1H-benzotriazol-1-y-l)methyl)-6-bromo-1H-benzoimidazol-2-yl)isoquinoline). Both complexes showed strong antitumor abilities against the colon cancer cell line (HCT116) and low cytotoxicity against the normal liver cell line (L-02). The DNA binding affinity was evaluated using CD and fluorescence spectroscopy, and the Ksv and Kapp values were further quantified, revealing that the complexes bound to DNA in the intercalation mode, and caused oxidative damage to pBR322 DNA. Furthermore, complex 1 interfered with the steady-state balance of redox and Ca2+ in HCT116 cells, as well as induced cell mitochondrial membrane potential (Δψm) collapse, ATP dissipation, ultimately arrested the cell cycle in G2 phase and induced cell apoptosis.

Hu, Pan;Shen, Shaohang;Zhao, Donghua;Wei, Hua;Ge, Jun;Jia, Feiyue;Zhang, Xiangxiang;Yang, Hu research published ã€?The influence of hydrophobicity on sludge dewatering associated with cationic starch-based flocculantsã€? the research content is summarized as follows. Coagulation/flocculation is an extensive and effective pretreatment technol. for improving the sludge dewaterability. A series of hydrophobically associated cationic starch-based flocculants (CS-DMRs) with different degrees of hydrophobicity but similar charge densities were designed and synthesized. The CS-DMRs exhibited excellent sludge dewatering performance. The dewaterability of sludge increased with the hydrophobicity of the CS-DMRs, and the filter cake moisture content (FCMC) and specific resistance to filtration (SRF) could be reduced from 95.47% and 7.09 x 10¹² m/kg to 79.26% and 2.258 x 10¹² m/kg, resp., at a constant pressure of 0.05 MPa after conditioned by the starch-based flocculant with the highest hydrophobicity at its optimal dose. Moreover, due to their amphiphilic structures, CS-DMRs could closely interact with the neg. charged extracellular polymeric substances (EPS), efficiently compress the protein and polysaccharide in EPS, and release the bound water. A second-order polynomial model was proposed according to the phenomenol. theory to quant. analyze the effect of hydrophobicity in these starch-based flocculants on the sludge dewaterability. The structure-activity relationship was built, and the optimal dose and corresponding FCMC could be theor. estimated accordingly. The results were in good agreement with the exptl. results. The dewatering mechanisms were also discussed in detail on the basis of the changes in the FCMC, SRF, capillary suction time, properties of sludge flocs, compression coefficient, microstructures of sludge cakes, EPS fractions and components, and spatial distributions of the proteins and polysaccharides. In addition to charge neutralization, the hydrophobic association effects of CS-DMRs played an important role in the formation of drainage channels and net-like porous structures in the sludge cake to improve its permeability and filterability. This study thus provided a good understanding of the structural effects of the starch-based flocculants on the sludge dewaterability. The results are greatly beneficial to the fabrication and utilization of environment-friendly and high-performance natural polymeric conditioners for sludge treatment.
