The expansive library of jadomycins

The jadomycin family of natural products were discovered from Streptomyces venezuelae ISP5230 in the 1990s. Subsequent identification of the biosynthetic gene cluster along with synthetic efforts established that incorporation of an amino acid into the polyaromatic angucycline core occurs non-enzymatically. Over two decades, the precursor-directed biosynthetic potential of the jadomycins has been heavily exploited, generating a library approaching seventy compounds. This review compiles the jadomycins isolated and characterized to date; these include jadomycins incorporating proteinogenic and non-proteinogenic amino acids, semi-synthetic derivatives, biosynthetic shunt products, compounds isolated in structural gene deletion studies, and deoxysugar sugar variant jadomycins produced by deletion or heterologous expression of sugar biosynthetic genes.
