Jadomycin

Chemical compound

A jadomycin is a natural product produced by Streptomyces venezuelae ISP5230 (ATCC10712), the organism which is most well known for making the antibiotic chloramphenicol. The name jadomycin is applied to a family of related angucyclines which are distinguished by the E ring, which is derived from an amino acid. The amino acid incorporation which forms the E-ring is a chemical reaction, rather than enzymatic, an uncommon occurrence in biosynthesis. As such a number of jadomycins incorporating different amino acids have been discovered. Jadomycin A was the first compound of this family to be isolated and constitutes the angucylic backbone with L-isoleucine incorporated into the E-ring. A related analog, jadomycin B, is modified by glycosylation with a 2,6-dideoxy sugar, L-digitoxose. Jadomycins have cytotoxic and antibacterial properties.
