Cone snails and plants used to develop oral drug for pain

18.04.2008
Molecules from cone snail venom and African plants are being used by Queensland researchers as a blueprint to develop an oral drug to treat chronic pain.

Professor David Craik and Dr Richard Clark from the Institute for Molecular Bioscience have received $218,275 from the National Health and Medical Research Council (NHMRC) to aid in translating their research into a product available for Australians to use.

Studies on the molecule they have developed have shown that it is effective in relieving neuropathic pain in animals.

“Neuropathic pain is one of the most severe forms of chronic pain, and very difficult to treat,” Dr Clark said.

“Regular pain occurs when the nervous system is stimulated by, for example, an injury, whereas neuropathic pain occurs when the nervous system itself is damaged.”

“Current treatments in neuropathic pain only provide meaningful relief for one in three patients, and all of the current market-leading drugs have serious side effects, as well as taking up to three weeks to begin to take effect.”

Peptides (small proteins) from cone snail venom have attracted recent attention from scientists, as they can target receptors with a high degree of accuracy, thus eliminating severe side effects.

But peptides also degrade rapidly in the body. Professor Craik and Dr Clark have overcome this problem by engineering a circular peptide, using a circular protein backbone discovered by Professor Craik and found in plants such as violets.

The NHMRC Development grant will allow the researchers to further test their molecule to fully establish its therapeutic potential.

“Successful outcomes from this project will provide additional confirmation of the suitability of our molecule as a treatment for neuropathic pain,” Dr Clark said.

“Armed with these data, we will be able to secure a commercial partner and develop this molecule into a tablet for sufferers of chronic pain.”

Im Focus: Megakaryocytes act as „bouncers“ restraining cell migration in the bone marrow

Scientists at the University Würzburg and University Hospital of Würzburg found that megakaryocytes act as “bouncers” and thus modulate bone marrow niche properties and cell migration dynamics. The study was published in July in the Journal “Haematologica”.

Hematopoiesis is the process of forming blood cells, which occurs predominantly in the bone marrow. The bone marrow produces all types of blood cells: red...

Im Focus: Artificial neural network resolves puzzles from condensed matter physics: Which is the perfect quantum theory?

For some phenomena in quantum many-body physics several competing theories exist. But which of them describes a quantum phenomenon best? A team of researchers from the Technical University of Munich (TUM) and Harvard University in the United States has now successfully deployed artificial neural networks for image analysis of quantum systems.

Is that a dog or a cat? Such a classification is a prime example of machine learning: artificial neural networks can be trained to analyze images by looking...

Im Focus: Extremely hard yet metallically conductive: Bayreuth researchers develop novel material with high-tech prospects

An international research group led by scientists from the University of Bayreuth has produced a previously unknown material: Rhenium nitride pernitride. Thanks to combining properties that were previously considered incompatible, it looks set to become highly attractive for technological applications. Indeed, it is a super-hard metallic conductor that can withstand extremely high pressures like a diamond. A process now developed in Bayreuth opens up the possibility of producing rhenium nitride pernitride and other technologically interesting materials in sufficiently large quantity for their properties characterisation. The new findings are presented in "Nature Communications".

The possibility of finding a compound that was metallically conductive, super-hard, and ultra-incompressible was long considered unlikely in science. It was...

Im Focus: Modelling leads to the optimum size for platinum fuel cell catalysts: Activity of fuel cell catalysts doubled

An interdisciplinary research team at the Technical University of Munich (TUM) has built platinum nanoparticles for catalysis in fuel cells: The new size-optimized catalysts are twice as good as the best process commercially available today.

Fuel cells may well replace batteries as the power source for electric cars. They consume hydrogen, a gas which could be produced for example using surplus...
