Implication

Isolation of novel polyketides shows strong antibacterial activity against Vibrio harveyi, highlighting potential for marine-derived compounds.

Key Points

  • To characterize new polyketides from Talaromyces indigoticus and evaluate their antibacterial properties.
  • Isolation of polyketides from rice culture medium extract
  • Use of comprehensive spectroscopic analysis for structure determination
  • Application of single-crystal x-ray diffraction for structural confirmation
  • Conducted antibacterial activity tests against various bacterial strains
  • Isolated talaroindiones A-C and identified two known diphenyl ether derivatives
  • Compound 4 showed broad-spectrum antibacterial activity, especially against Vibrio harveyi
  • Vibrio harveyi exhibited a minimum inhibitory concentration (MIC) of 2 µg/mL against compound 4
