New therapy for heart failure

15.10.2008
During heart failure the body reacts to the production of the hormone aldosterone. Too much aldosterone can stiffen and damage the muscles of the heart.

Dutch researcher Luc Roumen has optimised compounds that inhibit the production of this hormone and looked at their optimum dosage. The compounds were manufactured by the companies Schering-Plough and SyMO-Chem BV and a drug patent has been applied for.

Luc Roumen has developed a new therapy for the prevention of heart failure. The idea is to administer a drug that blocks the enzyme responsible for the production of aldosterone, namely cytochrome P450 11B2. The related enzyme 11B1 is involved in the production of other important hormones. Roumen searched for a highly selective drug that would only block 11B2, but not 11B1, to ensure a minimum of side effects when the drug is administered.

Computer simulation
Roumen examined the three-dimensional structure of both enzymes using computer simulations and was able to analyse the dynamic behaviour of the enzymes and a number of candidate drugs. This provided valuable information about the interactions preferred by the 11B2 enzyme. By optimising the interactions between the enzyme and a potential drug it was then possible to develop a number of very active and selective compounds. These can later be used as medicines.
Patent
The compounds developed were synthesised by the companies Schering-Plough (formerly Organon BV) and SyMO-Chem BV. The potential of the compounds was tested on cell cultures and rat models by Maastricht University. This collaboration resulted in valuable feedback, which could be used for verification of the computer models. A patent application has been made for a drug that reacted positively both in cell culture and in the rat models. The results are being documented by Maastricht University and Schering-Plough.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
