The rewards for studying natural products continue to be great. Each of the five structures on the cover has a storied past, and several have bRo5 scaffolds (Doak et al., Chem. 2014, 21, 1115–1142). C 15H 22O 5: Artemisinin (aka qinghaosu), discovered by Tu Youyou (Institute of Chinese Materia Medica, Beijing) from the plant Artemisia annua L., was the basis for half of the 2015 Nobel Prize in Physiology or Medicine. Currently, artemisinin is used to treat malaria induced by Plasmodium infections. This compound can now be produced by semisynthesis from artemisinic acid obtained by culturing genetically engineered yeast (Paddon and Keasling, Nat. 2014, 12, 355–367).

C 15H 21NO 6: Domoic acid is a marine-derived neurotoxin first discovered as a human health problem in 1987 by causing amnesic shellfish poisoning. It is biosynthesized in high yields when strains of Pseudo-nitzschia multiseries, a cosmopolitan marine diatom, are in association with marine bacteria (Kobayashi et al., Fish. 2009, 75, 771–776).
C 37H 67NO 13: Erythromycin is a venerable antibiotic used to treat a number of bacterial ailments, including respiratory tract infections, skin infections, chlamydia infections, and syphilis. It was discovered in 1949 at Lilly by culturing a strain of Streptomyces erythreus (now Saccharopolyspora erythraea), isolated from soil samples obtained in the Philippines by A. Many labs are investigating the erythromycin polyketide synthase gene cluster. C 39H 43N 3O 11S: Cyclosporin A is a powerful immunosuppressant therapeutic from the soil-derived fungus Tolypocladium inflatum and is broadly used in surgical transplantation. Its mechanism of action involves modulation of the immune system by interfering with T-cell growth. The presence of multiple N-Me groups plus a single R-amino acid residue are signatures for its biosynthetic production by a non-ribosomal route. C 62H 111N 11O 12: Ecteinascidin 743 (aka: ET-743, or Yondelis) is isolated from Ecteinascidia turbinata, a tunicate, and biosynthesized by a consortium of organisms (Rath et al., ACS Chem. Javelin Cs300 Cash Register User Manual.
2011, 6, 1244–1256). It was approved in the European Union (2007) for the treatment of advanced soft tissue sarcoma and in the U.S. (2015) for the treatment of liposarcoma. The trail for its discovery began in the 1960s through the U.S. National Cancer Institute's campaign to collect and bioscreen marine organisms.
In summary, the prospects for future outcomes based on natural products will continue to be substantial because less than 15% of the world's biodiversity has been explored for biologically active molecules.
