A team of scientists from The Scripps Research Institute has successfully reengineered an important antibiotic to kill the deadliest antibiotic-resistant bacteria. The compound could one day be used clinically to treat patients with life-threatening and highly resistant bacterial infections.
“[These results] have true clinical significance and chart a path forward for the development of next generation antibiotics for the treatment of the most serious resistant bacterial infections,” said Dale L. Boger, who is Richard and Alice Cramer Professor of Chemistry at The Scripps Research Institute and senior author of the new study. “The result could not be predicted. It really required the preparation of the molecule and the establishment of its properties.”
The compound synthesized is an analogue of the well-known commercial antibiotic vancomycin, an antibiotic of last resort, which is used only after treatment with other antibiotics has failed.
The new analogue was prepared in an elegant total synthesis, a momentous achievement from a synthetic chemistry point of view. “In addition to the elegantly designed synthesis,” said Jian Xie, postdoctoral fellow in Boger’s group and first author on the publication, “I am exceedingly gratified that our results could have the potential to be a great service to mankind.”
