New drug could reduce tissue damage after heart attack

27.04.2006


A study led by UCL (University College London) scientists has designed a new drug that inhibits the adverse effects of C reactive protein (CRP), a protein that contributes to tissue damage in heart attacks and strokes. The findings, published in the journal Nature, suggest that targeting CRP may produce both immediate and long-term clinical benefits following a heart attack.



CRP is normally present at trace levels in the blood but its concentration increases sharply in almost all diseases including trauma, infection, strokes and chronic illnesses such as rheumatoid arthritis and Crohn’s disease. CRP levels also rise dramatically after a heart attack. Patients with the greatest and most persistent increases in CRP concentration suffer higher mortality, and CRP is always deposited in and around the damaged heart tissue.

Inflammation contributes significantly to the extent of heart attack damage and this can be exacerbated by CRP. The UCL team has previously shown that human CRP increases the severity of damage in experimental models of heart attack and stroke. This first identified CRP as a valid therapeutic target. The present collaborative study has now rationally designed a potent small molecule inhibitor of CRP.


The new compound, bis(phosphocholine)-hexane, is bound by CRP, inhibits all CRP functions in the test tube, and blocks the tissue damaging effect of CRP in an experimental heart attack model.

Professor Mark Pepys, of the UCL Centre for Amyloidosis and Acute Phase Proteins, whose work on CRP has been supported by the Medical Research Council since 1979, says: “Although heart attacks are responsible for about one third of all deaths in developed countries, most patients survive a first heart attack. However, if they have a large scar, patients go on to develop heart failure which is eventually fatal. Reducing the immediate damage is thus critically important.

“We had previously invented a new mechanism of drug action for small molecules bound by target proteins. Coupled with knowledge of the structure and properties of CRP, we were able to design the CRP inhibitor."

“We now propose to develop a CRP inhibitor as rapidly as possible for testing in patients with heart attacks."

“The drug would be given as soon as patients arrived in hospital. If effective, it would reduce the amount of damage in the heart, thus limiting both early mortality and the size of the scar left in the heart."

“Provided adequate support is available, it should be possible to undertake clinical trials of CRP inhibition within a couple of years. If the treatment proves safe and effective, we also aim to investigate its effectiveness in strokes."

“It is likely that CRP contributes to tissue damage in a range of diseases in which CRP levels are greatly increased, and the inhibition of CRP may thus find broad application in medicine.”

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
