Novel polyoxazolines polymer drug delivery platform

17.05.2011
Oral and parenteral drug administration dominate the drug delivery market. The global market for oral drug delivery enhanced products was estimated to be worth around US$51 billion in 2009. Parenteral drug delivery is the second largest segment of the drug delivery market. It is presently valued at US$27 billion and is expected to reach US$51 billion by 2015 driven primarily by the launch of new biologics; the uptake of novel delivery platforms and the utilisation of controlled-release systems . Solubilization of hydrophobic drugs continues to be a key issue for drug delivery. The current invention relates to superior solubilization of hydrophobic drugs in aqueous solution through use of a novel amphiphilic polymer based on polyoxazolines with PEG-like properties (stealth effect, non-toxic, rapid renal clearance). The novel polyoxazoline polymers were used by inventors from the Technical University Munich for solubilizing several hydrophobic drugs from different compound classes like taxanes, cyclic

polypeptdes, protease inhibitors and polyene antibiotics by means of defined polymeric micelles. The resulting micelles were small (rh up to 30 nm), had a narrow size distribution (PD up to 0.12) and both a high loading capacity of up to 45% w/w and a high loading efficiency of more than 80%. Solubility was increased up to multiple thousand folds for the compounds tested. Lyophilization was possible without use of a cryo-protectant. Cytotoxicity studies showed no toxicity up to 20 mg/ml polymer. Animal studies for micelles loaded drugs showed at least similar effect with regard to tumor inhibition compared to commercial available drug products.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
