Studies find existing and experimental drugs active against MERS-coronavirus

20.05.2014

A series of research articles published ahead of print in the journal Antimicrobial Agents and Chemotherapy have identified a number of existing pharmaceutical drugs and compounds under development that may offer effective therapies against Middle East Respiratory Syndrome (MERS).

In the first study, researchers screened a library of 290 pharmaceutical drugs, either FDA-approved or in advanced clinical development for antiviral activity against the MERS coronavirus (MERS-CoV) and severe acute respiratory syndrome coronavirus (SARS-CoV) in cell culture. They found 27 compounds that were active against both viruses including some cancer drugs and antipsychotics.

"Repurposing of approved pharmaceutical drugs for new indications presents an attractive alternative to the normal paradigm of huge library screening against a specific viral enzyme," says author Matthew Frieman of the University of Maryland Medical School. "Given development times and manufacturing requirements for new products, repurposing of existing drugs is likely the best solution to rapidly identify therapeutics for outbreaks due to emerging viruses."

Researchers from the National Institutes of Health, the United States Army Medical Research Institute of Infectious Diseases and Zalicus Inc., Cambridge MA, were also involved in the study. A copy of the manuscript can be found online at http://bit.ly/asmtip0514e.

In the second study, researchers collaborating in the European antiviral research program SILVER used a similar methodology to screen a library of 348 FDA-approved drugs for anti-MERS-CoV activity in cell culture. They identified four compounds that inhibited MERS-CoV, SARS-CoV and Human Coronavirus 229E at relatively low concentrations. Two of the compounds were also identified by the U.S. study: the antimalarial drug chloroquine and the antipsychotic chlorpromazine.

"Although their therapeutic potential (alone or in combination) remains to be assessed in animal models, our findings may offer a starting point for treatment of patients infected with zoonotic coronaviruses like MERS-CoV," says corresponding author Eric Snijder of Leiden University Medical Center, the Netherlands. Researchers from the Rega Institute for Medical Research in Leuven, Belgium and the Erasmus Medical Center in Rotterdam, the Netherlands were also involved in the study.

The third and final study finds that an experimental compound, previously shown to block SARS-CoV replication, can inhibit replication of two other coronaviruses, MERS-CoV and mouse hepatitis virus.

"This study shows that it is possible to target multiple coronaviruses through broad-spectrum inhibitors," says corresponding author Stefan Sarafianos of the Bond Life Sciences Center at the University of Missouri, an author on the study. "This compound could serve as a lead for the development of effective broad-spectrum anti-coronavirus drugs."

Researchers from the University of Maryland Medical School and the University of Pennsylvania School of Medicine also contributed to the research. The manuscript can be found online at http://bit.ly/asmtip0514g.

Antimicrobial Agents and Chemotherapy is a publication of the American Society for Microbiology (ASM). The ASM is the largest single life science society, composed of over 39,000 scientists and health professionals. Its mission is to advance the microbiological sciences as a vehicle for understanding life processes and to apply and communicate this knowledge for the improvement of health and environmental and economic well-being worldwide.

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
