Self-Assembly of a Multi-Functional Hydrogel from a Branched Peptide Amphiphile and Its Effects on Bone Marrow Mesenchymal Stem Cells

In this work, a branched peptide amphiphile (B-PA) presenting RGD and IKVAV motifs was fabricated by solid-phase peptide synthesis and self-assembled into a nanofiber hydrogel in which rabbit bone marrow mesenchymal stem cells (BMSCs) were seeded and cultured for seven days. Specifically, 1 wt% B-PA was self-assembled into a nanofiber hydrogel with the addition of culture medium and observed using transmission electron microscopy. The B-PA with a molecular weight of 2191.72 and a purity >95% self-assembled into nanofibers with diameters from 6 to 8 nm and lengths ranging from hundreds of nanometers to several micrometers. BMSCs were acquired from rabbits using differential adherence methods and identified by flow cytometry for cell phenotype. The cells were stained with calcein acetoxymethyl ester/propidium iodide to assess cell viability, CCK-8 to assess cell cytotoxicity and proliferation, and Hochest 33342 to assess cell adhesion. They were also immunofluorescently labeled with microtubule-associated protein-2 (MAP-2), neurofilament protein (NF), and glial fibrillary acidic protein (GFAP) to assess cell transdifferentiation. The B-PA hydrogel provided platform upon which the CD29+/44+ cells adhered and proliferated, and it induced the transdifferentlation of cells into neural cells expressing the markers MAP-2, NF, and GEAR The hydrogel exhibited good cytocompatibility and multiple functions, and may therefore serve as a scaffold for neural tissue engineering.

Triacylglycerol Measurement in HeLa Cells

Lipid droplets store triacylglycerols (triglycerides) and sterol esters to regulate lipid and energy homeostasis. Triacylglycerol measurement is often performed during the investigation of lipid droplet formation and growth. This protocol describes a reliable method using a fluorometric lipid quantification kit to measure triacylglycerols extracted from HeLa cells, which were treated with oleic acid to trigger the formation of lipid droplets. The lipid quantification kit employs a lipid-binding molecule that emits bright fluorescence only when bound to extracted triacylglycerols, whose content can be quantified by a simple fluorescence readout.

New one-pot synthesis of anti-tuberculosis compounds inspired on isoniazid

A library of thirty N-substituted tosyl N’-acryl-hydrazones was prepared with p-toluenesulfonyl hydrazide, methyl propiolate and different aldehydes in a one-pot synthesis via an aza-Michael reaction. The scope of the reaction was studied, including aliphatic, isoprenylic, aromatic and carbocyclic aldehydes. The prepared collection was tested against Mycobacterium tuberculosis H37Rv. Nine analogs of the collection showed Minimum Inhibitory Concentration <= 10 mu M, of which the most active members (MIC of 1.25 mu M) were exclusively E isomers. In order to validate the mechanism of action of the most active acrylates, we tested their activity on a M. tuberculosis InhA over-expressing strain obtaining MIC that consistently doubled those obtained on the wild type strain. Additionally, the binding mode of those analogs on M. tuberculosis InhA was investigated by docking simulations. The results displayed a hydrogen bond interaction between the sulfonamide and Ile194 and the carbonyl of the methyl ester with Tyr 158 (both critical residues in the interaction with the fatty acyl chain substrate), where the main differences on the binding mode relays on the hydrophobicity of the nitrogen substituent. Additionally, chemoinformatic analysis was performed to evaluate in silico possible cytotoxicity risk and ADME-Tox profile. Based on their simple preparation and interesting antimycobacterial activity profile, the newly prepared aza-acrylates are promising candidates for antitubercular drug development.

Selective Synthesis of Benzothiophene-Fused Polycyclic, Eight-Membered N-Heterocycles via Amine-Mediated Three-Component Domino Strategy

A product-selective strategy was used to synthesize benzothiophene-fused polycyclic, eight-membered N-heterocycles via a three-component domino reaction of thioisatins under catalyst-free conditions. The reaction between tryptamine, thioisatin, and bromoacetophenone produced benzothiophene-fused polycyclic compounds. In contrast, using D-tryptophan methyl ester hydrochloride instead of tryptamine afforded benzothiophene-fused eight-membered N-heterocycles. DFT calculations showed that the benzothiophene-fused polycyclic compounds formed via the Pictet-Spengler reaction. However, the ester group in D-tryptophan methyl ester hydrochloride changed the reaction pathway and produced benzothiophene-fused eight-membered N-heterocycles.

Dominant Factor of Bond-Exchange Rate for Catalyst-Free Polyester Vitrimers with Internal Tertiary Amine Moieties

Catalyst-free vitrimers have attracted attention for practical application of the vitrimer concept, which requires fundamental knowledge of physical property tuning. We prepared catalyst-free vitrimers by cross-linking amorphous polyesters bearing COOH side groups with tetraepoxy compounds bearing tertiary amines (4,4′-methylenebis(N,N-diglycidylaniline), abbreviated as Mb-epoxy). The obtained network possessed ester and OH groups, and the amino moieties worked as internal catalysts for trans-esterification-based bond exchange. The competing effect of cross-link density and concentration of amines was investigated for samples with different fractions of Mbepoxy, revealing that cross-link density, which governs chain mobility, was the dominant factor in the determination of bond-exchange rate.

Preparation and characterization of composite quasi-solid electrolytes composed of 75Li(2)S center dot 25P(2)S(5) glass and phosphate esters

Mechanical properties and ionic conductivities of solid electrolytes are important factors influencing the performance of all-solid-state batteries. This study investigates composite quasi-solid electrolytes composed of Li2S-P2S5 glass and a phosphate ester, prepared via planetary ball milling, and the relative densities of the powder-compressed pellets, formed using the composite quasi-solid electrolytes. Dense pellets of the Li2S-P2S5 glass electrolyte are obtained via addition of phosphate esters; the relative densities increase from 90.6% to 93.1%, without the ionic conductivities decreasing, upon addition of a small quantity of tris (2, 2, 2-trifluoroethyl) phosphate to the Li3PS4 glass. The addition of small quantities of phosphate esters to sulfide solid electrolytes is effective in improving the formability of these solid electrolytes.

Conformational Control of the Photodynamics of a Bilirubin Dipyrrinone Subunit: Femtosecond Spectroscopy Combined with Nonadiabatic Simulations

The photochemistry of bilirubin has been extensively studied due to its importance in the phototherapy of hyperbilirubinemia. In the present work, we investigated the ultrafast photodynamics of a bilirubin dipyrrinone subunit, vinylneoxanthobilirubic acid methyl ester. The photoisomerization and photocyclization reactions of its (E) and (Z) isomers were studied using femtosecond transient absorption spectroscopy and by multireference electronic structure theory, where the non-adiabatic dynamics was modeled with a Landau-Zener surface hopping technique. The following picture has emerged from the combined theoretical and experimental approach. Upon excitation, dipyrrinone undergoes a very fast vibrational relaxation, followed by an internal conversion on a picosecond time scale. The internal conversion leads either to photoisomerization or regeneration of the starting material. Further relaxation dynamics on the order of tens of picoseconds was observed in the ground state. The nonadiabatic simulations revealed a strong conformational control of the photodynamics. The ultrafast formation of a cyclic photochemical product from a less-populated conformer of the studied subunit was predicted by our calculations. We discuss the relevance of the present finding for the photochemistry of native bilirubin. The work has also pointed to the limits of semiclassical nonadiabatic simulations for simulating longer photochemical processes, probably due to the zero-point leakage issue.

Oxygen-Rich Bis(trinitroethyl esters): Suitable Oxidizers as Potential Ammonium Perchlorate Replacements

In the area of solid rocket propellants, research efforts are ongoing to find suitable oxidizers as ammonium perchlorate (AP) replacements. On the one hand, AP’s performance data are excellent; on the other hand, AP and its combustion products lead to health and environmental issues. Herein, the nitraminodiacetic acid bis(2,2,2-trinitroethyl ester) (NABTNE) is presented as a green AP alternative and is compared to the bis(trinitroethyl ester) of malonic acid (MaBTNE). Simple syntheses based on economic starting materials furnished both compounds, with NABTNE having a positive oxygen balance (according to CO), a density of 1.84 g cm(-3) (@T = -118 degrees C), and a decomposition point of 180 degrees C. The density of MaBTNE (delta = 1.81 g cm(-3) @T = -147 degrees C) and the thermal stability (T-dec = 157 degrees C) are also advantageous. NABTNE as a moderately sensitive and the most promising derivative was shown to be of good stability toward long-term storage. Moreover, mixtures for a potential application in solid rocket formulations were calculated using EXPLOS (V 6.03).
