Reference Reading

1. Constitution and absolute stereochemistry of the antibiotic sarubicin A
K Eckardt, D Tresselt, W Ihn, M Kajtár, J Angyán, L Radics, M Hollósi J Antibiot (Tokyo). 1983 Aug;36(8):976-9. doi: 10.7164/antibiotics.36.976.
By spectral (UV-VIS, IR, NMR, MS and CD) methods the quinone antibiotics sarubicin A and U-58,431 were shown to have identical constitution and stereochemistry. Chiroptical data and their theoretical analysis have settled the common absolute configuration as 5S, 6R, 8R, 10R.
2. Fermentation, isolation, characterization and structure of antibiotic U-58,431
L Slechta, C G Chidester, F Reusser J Antibiot (Tokyo). 1980 Sep;33(9):919-23. doi: 10.7164/antibiotics.33.919.
A new antibiotic U-58,431 has been isolated from the fermentation broth of Streptomyces helicus DIETZ and LI, sp. n. (UC-5837) and the structure of this antibiotic, namely, 6-amino-3,4,5,8-tetrahydro-4,9-dihydroxy-3-methyl-5,8-dioxo-1,4-ethano-1H-2-benzopyron-7-carboxamide has been determined by X-ray crystallography. The antibiotic inhibits a variety of Gram-positive and Gram-negative bacteria in vitro. However, it is toxic to mice and does not protect experimentally infected animals when administered at the maximum tolerated dose.
