"We want to accelerate the discovery of new compounds that can be turned into effective drugs," said Professor Tony Maxwell from the John Innes Centre, a key player in "More Medicines for Tuberculosis", a new European research project.
Two billion people are currently infected with TB and three million die every year. TB causes more deaths than any other infectious disease. Rates are increasing, especially in sub-Saharan Africa, where people with HIV are particularly vulnerable. It is also associated with intravenous drug use and increased rates may be linked to immigration.
"The bacterium is difficult to get at," said Professor Maxwell. "It is slow growing, spends a lot of time hidden in cells before it makes itself known, and has very tough cell walls of its own."
Treatment is relatively long term, requiring a drug regime over four to six months. Non-compliance is a problem, exacerbating the challenge caused by resistant strains.
"Drug discovery research for tuberculosis is dependent on academic labs and no single lab can do it", said Professor Maxwell.
Scientists from 25 labs across Europe will collaborate on the new project including some groups in the US and India.
The John Innes Centre scientists will focus on compounds that target DNA gyrase, a target that they have already established as effective and safe. They will receive compounds from European collaborators including AstraZeneca. They will screen those that knock out DNA gyrase. Their research will continue on those compounds that are effective both against the target (DNA gyrase) and the bacterium.
Working on new compounds to hit known targets, rather than compounds that may struggle to access bacterial cells or that may have unknown effects in humans, will provide a quicker route to clinical trials.
"Finding new antibiotics that work is only the first step," warns Professor Maxwell.
The next stage will be to determine how exactly the antibiotic compound operates and whether it has a hope of working in a clinical environment.
One group of compounds under study at JIC are naphthoquinones, originally extracted from plants including the toothbrush tree, Euclea natalensis.
The John Innes Centre is an institute of the BBSRC.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
