New Enhanced Neuroprotective Properties of Undecylenic Acid

Here is an interesting article on the enhanced neuroprotective effects of undecylenic acid.

Undecylenic acid, a synthetic unsaturated fatty acid obtained from castor oil is a well-known potent antifungal agent. In 2012, scientists from Korea found that undecylenic acid has the ability to inhibit µ-Calpain activity, a factor responsible for neurological disorders like Alzheimer’s disease.  This showed the neuroprotective effects of Undecylenic acidundecylenic acid.

Now scientists from Poland have done an experiment to improve the efficiency of neuroprotective effects of undecylenic acid by targeting it using polyelectrolyte coated nanocapsules. Core shell nanocapsules were prepared using nanoemulsification and the layer by layer technique. The average size of nanocapsules was around 80nm and the concentration was 2.5×1010 particles/ml. The nanocapsules were coated with either polycation or polyanion layers.

Biocompatibility of the synthesized nanocarriers was evaluated in SH-SY5Y human neuroblastoma cell line using cell viability/toxicity assays.

Results showed that nanocapsules coated with PLL and PGA were non-toxic to the human neuroblastoma cell line, thereby showing its potential to be used as a carrier of undecylenic acid.  Further research showed that nanoencapsulated form of undecylenic acid was biocompatible and more effective against staurosporine-induced damage in lower concentrations than those of the same drug added directly to the culture medium.

This shows that undecylenic acid could be more effective in nanoencapsulated form against neurological disorders.

Pure Polyurethane and Castor Oil Based Polyurethane: Synthesis and Characterization

Scientists from Malaysia performed an experiment to compare the physico-chemical properties of high performance polyurethane prepared using pure poly propylene glycol (PPG) and that prepared from PPG and castor oil.castor oil polyurethane

Characterization studies indicated the presence of large -CH stretching in castor oil mixed polyurethane with larger oxidative thermal stability over pure PPG polyurethane. The tensile properties were found to be almost comparable showing that mixed polymers can be used in future to overcome environmental and economic crisis.

Synthesis and Characterization of Castor Oil Based Hybrid Polymers and Their Polyurethane-Urea/Silica Coatings

Scientists performed an experiment to synthesize castor oil based hybrid polymers castor oil polyurethaneand their polyurethane urea-silica coatings. New acrylated alkoxysilane castor oil (AASCO) with hydrolysable –Si–OCH3 was synthesized from CO, maleic anhydride and 3-(Trimethoxysilyl) propyl methacrylate via free radical copolymerization method.

Characterization studies showed that castor oil modified silane based hybrid coatings had better mechanical, viscoelastic properties.

In-Situ Epoxidation of Castor Oil Using Heterogeneous Acidic Ion-Exchange Resin Catalyst (IR-120) for Bio-Lubricant Application

Scientists from India conducted an experiment to prepare castor oil epoxide using castor oilheterogeneous acidic ion-exchange resin catalyst (IR-120) for biolubricant application. Epoxidation reaction was carried out at 60°C using IR-120 as a catalyst, acetic acid as an oxygen carrier and hydrogen peroxide as an oxygen donor.

Characterization analysis showed that castor oil epoxide could be used as a potential biolubricant basestock in hydraulic lubricant application.

Production of Oriented Strand Board (OSB) with Schizolobium amazonicum and Castor Oil Based Polyurethane Resin

Researchers from Brazil performed an experiment to evaluate the feasibility of OSB Castor oilpanel production Parica (Schizolobium amazonicum) wood particles bonded by castor oil based polyurethane resin. Three different resin contents (8%, 10% and 12%) were evaluated.

Results showed that panels produced with 8% of resin content were best as they were compatible with norm requirements and used less resin in the manufacturing process. Thus Parica wood and castor oil based polyurethane resin in the OSB panels production is feasible.

Electroactive Polyurethane/Siloxane Derived From Castor Oil as a Versatile Cardiac Patch

Scientists from Italy conducted an experiment to synthesize electroactive polyurethane/siloxane films from castor oil for use as a cardiac patch. The electroactive films containing aniline tetramer were prepared through sol gel reaction of trimetcastor oil polyurethanehoxysilane functional intermediate polyurethane prepolymers obtained from castor oil and polyethylene glycol.

Physicochemical, mechanical and electrical conductivity of samples were evaluated and correlated with their structural characteristics. Results showed that the prepared films were compatible with proliferation of C2C12 and had the potential to enhance myotube formation even without electrical stimulation.

Toughening of Poly(L-Lactide) by Polyester-Urethane Networks Based on Castor Oil-Modified Ɛ-Caprolactone Oligomers

Scientists from Japan conducted an experiment to increase the toughness of poly(L-lactide) (PLLA) with the help of polyester urethane networks obtained from castor oil based oligomers.  Hydroxy-terminated castor oil-modified ɛ-castor oilcaprolactone oligomers (CO-CLOns) were prepared by ring opening polymerizations of ɛ-caprolactone initiated with castor oil. It was then allowed to react with poly(L-lactide) which produced semi-interpenetrating polymer networks composed of TDI-bridged CO-CLOn networksand PLLA.
