The breakthrough is another major step forward on the journey to develop a commercially viable drug version based on teixobactin -- a natural antibiotic discovered by US scientists in soil samples in 2015 which has been heralded as a "gamechanger" in the battle against antibiotic resistant pathogens such as MRSA and VRE.

Scientists from the University of Lincoln, UK, have now successfully created a simplified, synthesised form of teixobactin which has been used to treat a bacterial infection in mice, demonstrating the first proof that such simplified versions of its real form could be used to treat real bacterial infection as the basis of a new drug.

Team - Lincoln - Library - Versions - Teixobactin

The team at Lincoln developed a library of synthetic versions of teixobactin by replacing key amino acids at specific points in the antibiotic's structure to make it easier to recreate. After these simplified synthetic versions were shown to be highly potent against superbug-causing bacteria in vitro -- or test tube -- experiments, researchers from the Singapore Eye Research Institute (SERI) then used one of the synthetic versions to successfully treat a bacterial infection in mice.

As well as clearing the infection, the synthesised teixobactin also minimised the infection's severity, which was not the case for the clinically-used antibiotic, moxifloxacin, used as a control study. The findings are published in the Journal of Medicinal Chemistry.

People - Drug - Infections - Year - Development

It has been predicted that by 2050 an additional 10 million people will succumb to drug resistant infections each year. The development of new antibiotics which can be used as a last resort when other drugs are ineffective is therefore a crucial area of study for...
