REpotentiating BEta Lactam antibiotics (REBEL)
Resistance against β-lactam antibiotics is a serious health issue. Often it is caused by bacteria producing enzymes capable of inactivating these antibiotics, β-lactamases. This can be prevented by combining the antibiotic with a compound able to inhibit the bacterial enzyme.
Aim
The aim of this project was to find new β-lactamase inhibitors. To achieve this a large botanical extract library was screened for β-lactamase inhibitory activity, and several inhibiting compounds were isolated and identified. Further research on these compounds is needed to determine their suitability for medicinal application, and ultimately to effectively fight β-lactam resistant bacteria.
Results
Besides the discovery of several compounds with beta-lactamase inhibitory activity, the project has yielded a number of useful bioassays. Also techniques and work-flows were developed for the isolation and identification of bio-active compounds from complex mixtures.
