Scientists have identified polyketide natural product biosynthetic machinery, enabling the creation of novel therapeutic compounds. This advancement allows for the production of altered structural analogues, particularly in the antibiotic field.

Area of Science:

  • Biochemistry
  • Natural Product Chemistry
  • Medicinal Chemistry

Background:

  • Polyketide natural products are a rich source of therapeutics, including antibacterials, anticancer agents, antifungals, and cholesterol-lowering drugs.
  • Significant progress in identifying the biosynthetic machinery for polyketide natural products has occurred over the last decade.

Purpose of the Study:

  • To explore the potential of manipulating polyketide biosynthetic machinery.
  • To generate novel structural analogues of polyketide natural products not accessible through traditional synthetic methods.

Main Methods:

  • Identification and characterization of polyketide biosynthetic enzymes and pathways.
