Researchers Streamline Molecular Assembly Line to Design, Test Drug Compounds
Researchers from North Carolina State University have found a way to fine-tune the molecular assembly line that creates antibiotics via engineered biosynthesis. The work could allow scientists to improve existing antibiotics as well as design new drug candidates quickly and efficiently.
Bacteria – such as E. coli – harness biosynthesis to create molecules that are difficult to make artificially.
“We already use bacteria to make a number of drugs for us,” says Edward Kalkreuter, former graduate student at NC State and lead author of a paper describing the research. “But we also want to make alterations to these compounds; for example, there’s a lot of drug resistance to erythromycin. Being able to make molecules with similar activity but improved efficacy against resistance is the general goal.”
