Infobox references

Kendomycin is an antitumor macrolide antibiotic first isolated from the bacteria Streptomyces violaceoruber.^[2] It has potent activity as an endothelin receptor antagonist and anti-osteoporosis agent.^[3] It also has strong cytotoxicity against various tumor cell lines.^[2]

Total synthesis

Because of its potent biological activities, kendomcyin has attracted interest as a target of total synthesis. The first total synthesis of kendomycin was accomplished by Lee and Yuan in 2004.^[4] The total number of syntheses stands at 6 ^{[5][6][7][8][9]}
