Research could lead to new drugs for major diseases

11.06.2012
Researchers at the University of Gothenburg, Sweden, are working to develop substances that can prevent parasites, bacteria and fungi from producing essential proteins, research that could, in the long term, lead to new drugs for several major diseases.

The World Health Organization (WHO) has announced that aminoacyl-tRNA synthetases – a type of enzyme – are important targets for the development of new drugs for several major diseases such as cancer, various parasitic diseases and bacterial and fungal infections.

These enzymes are involved in the production of proteins (protein synthesis) in all organisms. Their job is to ensure that the right amino acid is linked to the growing protein chain. These enzymes are essential for all living organisms.

Challenging research field
Researchers at the University of Gothenburg are currently undertaking basic research in this challenging field. The aim is to prevent the enzyme from producing proteins in bacteria, parasites or fungi, without stopping it from functioning in the human body.

"We're collaborating with researchers in several countries," says researcher Itedale Namro Redwan. "Our role has been to design and to synthesise substances that can be used for the development of drugs against parasitic diseases."

Looking for an effective substance
The enzymes' job of ensuring that the right amino acid is linked to the growing protein chain works in the same way in all types of cell, be they human or parasitic.

"The real challenge is identifying substances that act on enzymes in the parasite alone, without affecting the human enzymes at the same time," says Itedale Namro Redwan, who is making substances that can prevent bacterial and parasitic enzymes from functioning, but do not affect human enzymes. If this proves possible, it will help in the development of drugs for several major diseases.

"One of our main objectives has been to produce potent and selective substances that can be used to gain understanding of how these enzymes work. A greater understanding of their function would contribute to the development of medication for diseases like elephantitis."

Could prevent major diseases
Elephantitis, also known as filiaris, affects more than 120 million people in the developing world, and is caused by a worm that lives in the infected person's lymphatic vessels.

The potentially active molecules are being designed using computer-based molecular modelling techniques, with the resulting molecules subsequently synthesised via various chemical reactions.

"One of the best things about being a medicinal chemist is getting to plan a synthetic pathway that'll result in a specific substance, starting the reaction and then realising that the reaction's has worked," says Itedale Namro Redwan. "Better still is finding out that the molecule has performed as expected in a biological test."

The activity of the synthesised substances is assessed by partners through biological testing on, for example, aminoacyl-tRNA synthetase isolated from E. coli or filiaris parasites.

The thesis "Design and Synthesis of Potential Aminoacyl-tRNA Synthetase Inhibitors" has been successfully publicly defended at the University of Gothenburg on 11 May 2012.

Im Focus: It’s All in the Mix: Jülich Researchers are Developing Fast-Charging Solid-State Batteries

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.

The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
