Polyglycerol polyricinoleate (PGPR, E-476) is a powerful water-in-oil emulsifier 1–5 used to manufacture stable pan release agents for the bakery industry and to stabilize low fat margarine systems with high water content. However, its main application is in the chocolate and confectionery industry,6,7 since it improves the flow properties of chocolate and vegetable fat coatings by lowering the...

Poly(glycerol sebacate) methacrylate (PGS-M) has tunable mechanical properties, making it suitable for soft tissue engineering.

Water-soluble perylene tetracarboxylic acid bisimides (PBIs) with terminally linked polyglycerol dendrons of four different generations have been synthesized. These PBI dyes reveal a strong dendritic effect, enabling outstanding fluorescence quantum yields in water up to almost 100% for the highest dendron generation.

The industry under consideration uses chiefly the phthalate plasticizers: predominantly dibutyl phthalate (DBP) and higher alkyl phthalates (DAP-789); periodically dioctyl phthalate (DOP), diisooctyl phthalate (DIOP), and benzyl butyl phthalate (BBP). Some formulations contain small amounts of one of the sebacates (dibutyl sebacate, DBS, or dioctyl sebacate, DOS) or adipates (dibutyl adipate, D...

In this study, the feasibility of using copper oxide (CuO) as an interface for the coupling of liquid chromatography (LC) and Fourier-transform infrared (FTIR) spectroscopy was investigated. CuO exhibits low absorption in the 4000 to 1000 cm-1 FTIR spectral region. In addition, LC-FTIR using CuO as the interface was extended to the analysis of sample mixtures containing benzamide and dioctyl se...

The current epidemic of infections caused by antibiotic-resistant gram-positive bacteria requires the discovery of new drug targets and the development of new therapeutics. Lipoteichoic acid (LTA), a cell wall polymer of gram-positive bacteria, consists of 1,3-polyglycerol-phosphate linked to glycolipid. LTA synthase (LtaS) polymerizes polyglycerol-phosphate from phosphatidylglycerol, a reactio...

An elastomeric scaffold containing poly(glycerol sebacate) and hydroxypropyl-?-cyclodextrin was developed for soft tissue engineering.

A pharmacologically active agent was easily extracted by aqueous or organic solvents from laboratory plastic tubes (Falcon Blue Max) and has been chemically identified as bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate. This compound (approximately 12 micrograms per tube approximately 25 nmol) blocked 1,4-dihydropyridine-sensitive 45Ca2+ uptake into GH3 cells with an IC50 value of 3.6 microM, inh...

Polyglycerol monolaurates are generally recognized as safe food additives and commonly used emulsifiers. In this study, the antimicrobial effect of four polyglycerol on two Gram-positive bacteria (Staphylococcus aureus Bacillus subtilis) Gram-negative (Escherichia. coli Pseudomonas aeruginosa) were investigated. The minimum inhibitory concentration (MIC) diglycerol monolaurate (PG2ML), triglyce...

Hydrogels and nanogels have emerged as promising materials for biomedical applications owing to their large surface area tunable mechanical chemical properties. Their is well suited bioconjugation, whilst the interior porous network can be utilized transport of valuable biomolecules. The use biocompatible hydrophilic building blocks/linkers preparation hydrogels not only avoids undesired side e...
