ABSTRACT
Indanomycins are a class of secondary metabolites of microorganisms with a trans-tetrahydroindan (indane) ring. These compounds generally have good antibacterial, insecticidal and antitumor biological activities, which have caused wide interest for medicinal chemists and biologists. This review summarizes the research progress of the discovery, biological activity, chemical synthesis and biosynthesis of indanomycin compounds since 1979 and provides scientific reference for the research and development of indanomycin antibiotics.
ABSTRACT
Erythromycin A is a clinically important macrolide antibiotic with broad-spectrum activity. Its biosynthesis involves the formation of the 14-membered skeleton catalyzed by polyketide synthases, and the modification steps such as hydroxylation, glycosylation and methylation. Based on the understanding of the biosynthetic mechanism, it is reliable to genetically manipulate the erythromycin A-producing strain for production improvement and structure modification. In this paper, we reviewed the progress regarding erythromycin A in high-producing strain construction and chemical structure derivation, to provide insights for further development.
