Anti-senescence effect and molecular mechanism of the major royal jelly proteins on human embryonic lung fibroblast (HFL-I) cell line

Royal jelly (RJ) from honeybee has been widely used as a health promotion supplement. The major royal jelly proteins (MRJPs) have been identified as the functional component of RJ. However, the question of whether MRJPs have anti-senescence activity for human cells remains. Human embryonic lung fibroblast (HFL-I) cells were cultured in media containing no MRJPs (A), MRJPs at 0.1 mg/ml (B), 0.2 mg/ml (C), or 0.3 mg/ml (D), or bovine serum albumin (BSA) at 0.2 mg/ml (E). The mean population doubling levels of cells in media B, C, D, and E were increased by 12.4%, 31.2%, 24.0%, and 10.4%, respectively, compared with that in medium A. The cells in medium C also exhibited the highest relative proliferation activity, the lowest senescence, and the longest telomeres. Moreover, MRJPs up-regulated the expression of superoxide dismutase-1 (SOD1) and down-regulated the expression of mammalian target of rapamycin (MTOR), catenin beta like-1 (CTNNB1), and tumor protein p53 (TP53). Raman spectra analysis showed that there were two unique bands related to DNA synthesis materials, amide carbonyl group vibrations and aromatic hydrogens. These results suggest that MRJPs possess anti-senescence activity for the HFL-I cell line, and provide new knowledge illustrating the molecular mechanism of MRJPs as anti-senescence factors.

Configurationally flexible zinc complexes as catalysts for rac-lactide polymerisation

Zn(N(SiMe3)(2))(2) was reacted with pyridinemethanol and R,R-N,N-di(methylbenzyl)-2,5-diiminopyrrole (L1H) to afford the dimeric complex (L1)(2)Zn-2(-OR)(2). The complex showed moderate activity in rac-lactide polymerization to heterotactic polymer (P-r = 0.75). 2,4-Di-tert-butyl-6-aminomethyl-phenol ligands with amino = N,N,N,N-tetramethyldiethylenetriamine (L2H) or di-(2-picoly)amine (L3H) were reacted with ZnEt2 to form (L2)ZnEt and with Zn(N(SiMe3)(2))(2) to form the respective amide complexes. All complexes, including (L1)(2)Zn-2(-OR)(2) were characterised by X-ray diffraction studies. (L2)ZnEt was unreactive toward ethanol, but the amide complexes afforded (L2)ZnOEt and (L3)ZnOEt upon reaction with ethanol, which were used in rac-lactide polymerization without isolation. All complexes racemise readily at room temperature and show apparent C-s-symmetry in their NMR spectra. The ethoxide complexes were highly active in lactide polymerization, with (L3)ZnOEt reaching full conversion in 15 min at 0.5 mM catalyst concentration at room temperature. In both cases, introduction of a second donor arm on the central nitrogen introduced a slight bias for isotactic monomer enchainment (P-m = 0.55-0.60), which for (L3)ZnOEt was dependent on catalyst concentration.

Highly Conductive Ionic Liquid Electrolytes for Potassium-Ion Batteries

Potassium-ion batteries (K-ion batteries; KIBs) are attractive as high-voltage, low-cost energy storage devices. Ionic liquids (ILs) are potential candidates as safe and high-performance electrolytes for large-scale devices. Imidazolium-based ILs are known to possess high ionic conductivities and moderate electrochemical stabilities. In this study, we report the physicochemical and electrochemical properties of K[FSA]- [C(2)C(1)im][FSA] (FSA = bis(fluorosulfonyl)amide; C(2)C(1)im = 1-ethyl-3-methylimidazolium) ILs as new electrolytes for KIBs. A phase diagram constructed from differential scanning calorimetry results indicates that the melting point of this IL is below 273 K at compositions of x(K[FSA]) = 0-0.20 (x(K[FSA]) = molar fraction of K[FSA]). The viscosity, ionic conductivity, and density of the IL were measured for x(K[FSA]) = 0-0.20. The ionic conductivity at x(K[FSA]) = 0.20 is 10.1 mS cm(-1) at 298 K, which is comparable to that of typical organic solvent-based KIB electrolytes and higher than that of other ionic liquid electrolytes for KIBs. The electrochemical stability of M[FSA]-[C2C1 im][FSA] (x(M[FSA]) = 0.20; M = K, Na, and Li) ILs was determined by cyclic voltammetry measurements. The K-based IL exhibits the widest electrochemical window of 5.19 V due to the negative redox potential of the K+/K couple. Thus, the K[FSA]-[C2C1 im][FSA] ionic liquid is expected to be a highly conductive KIB electrolyte.

Nickel/Briphos-Catalyzed Direct Transamidation of Unactivated Secondary Amides Using Trimethylsilyl Chloride

Direct transamidation of secondary amides was developed via nickel catalysis. In the presence of trimethylsilyl chloride and manganese, Ni(diglyme)Cl-2 with a Briphos ligand efficiently promoted the transamidation of N-aryl benzamide derivatives with primary amines to afford the corresponding secondary amides in moderate to good yields. Primary amines bearing electron-donating groups gave higher yields of the transamidation products.

H-bonding binary organocatalysis promoted amine-initiated ring-opening polymerizations of lactide from polysarcosine to diblock copolymers

Alcohol-initiated ring-opening polymerization (ROP) of cyclic esters for synthesizing polyesters was well established, but amine-initiated ROP of cyclic esters was rare. A challenge is slow initiation and fast propagation in the amine-initiated ROPs. To address the difficulties, an ionic H-bond donor (iHBD) and H-bond acceptor (HBA) binary organocatalysis in amine-initiated ROP of lactide (LA) was developed. Guanidinium hexahydro-2H-pyrimido [1,2-a] pyrimidin-1-ium [(HppH(2))(+)] and tertiary amine sparteine (SP), cooperatively played the role of iHBD/HBA binary catalysts, efficiently promoted ROP of LA from amine initiators toward polylactide (PLA) and polysarcosine-block-polylactide diblock copolymer (PSar-b-PLA). Benzyl amine and N-methylbenzylamine initiated ROPs of LA under mild conditions produced PLAs with predictable molecular weights (M-n,M-NMR = 2.9-17.1 kg mol(-1)) and narrow dispersities (D-M,D-SEC = 1.13-1.23). Macroinitiator PSar copolymerized with LA under the iHBD/HBA catalysis, producing PSar-b-PLAs with controlled molecular weights (M-n,M-NMR = 5.7-14.8 kg mol(-1)) and low dispersities (D-M,D-SEC = 1.16-1.21). Kinetics and chain extension experiments confirmed that the amine-initiated ROP of LA in presence of (HppH(2))+BE4-/SP was in controlled/living manner. H-1 NMR, C-13 NMR, SEC, and MALDI-ToF MS analyses indicated that the obtained PLA was exclusively initiated from the corresponding amine with amide linkage. An iHBD/HBA binary activation mechanism was proposed.

Synthesis and antimicrobial activities of novel sorbic and benzoic acid amide derivatives

A series of sorbic and benzoic acid amide derivatives were synthesized by conjugating sorbic acid (SAAD, a(l)-a(7)) or benzoic acid (BAAD b(1)-b(6)) with amino acid esters and their antimicrobial activities were investigated against Escherichia coll., Bacillus subtilis and Staphylococcus aureus, mixed bacteria from rancid milk, Saccharomyces cerevisiae, and Aspergillus niger. The antimicrobial activity of sorbic acid amides was better than that of benzoic acid amides. The minimum inhibitory concentrations (MIC) of compound isopropyl N-[1-oxo-2, 4-hexadien-1-yl]-L-phenylalaninate (a(7)) were 0.17 mM against B. subtilis, and 0.50 mM against S. aureus, while the MIC values of sorbic acid were more than 2 mM respectively. Also, compound a(7) displayed pH-independent antimicrobial activity in the range of pH 5.0-9.0 and was effective at pH 9.0. These results demonstrated that the conjugation of sorbic acid with amino acid esters led to significant improvement of in vitro antimicrobial attributes, but little effect was observed for benzoic acid amide derivatives.

Hydrogen bond donor functionalized dioxido-molybdenum(VI) complexes as robust and highly efficient precatalysts for alkene epoxidation

The synthesis of four novel, tridentate aminophenolate ligands HL1-HL4, bearing amide functionalities is reported. Reaction of these ligands with a dioxido molybdenum(VI) precursor led, depending on the choice of solvent, to mononuclear complexes of the type [MoO2L(OMe)] (2, 4, 6) or dinuclear complexes [{MoO2L}(2)(mu-O)] (1, 3, 5, 7), containing one facially, tridentate ONO-ligand per metal center. This synthetic discrimination between dinuclear and mononuclear complexes allows for a comparison between structures and reactivity. Complexes 1-7 were found to be highly active catalysts in the epoxidation of several internal and terminal alkenes. With tent-butyl hydroperoxide (TBHP) as oxidant, precatalyst loadings of 0.0005 mol% (5 ppm) could be realized leading to turnover numbers of up to 110000. The pre-catalysts also allowed for the use of hydrogen peroxide (0.1 mol% precatalyst) as oxidant as well as various alcohols as green solvents, such as ethanol or even tert-butanol (usually an inhibitor of epoxidation).
