Reference Reading
1. Sarubicin b, a new quinone antibiotic, isolated from the fermentation broth of a streptomyces strain
K Eckardt, D Tresselt, W Ihn, G Bradler, G Reinhardt J Antibiot (Tokyo). 1982 Dec;35(12):1638-40. doi: 10.7164/antibiotics.35.1638.
Sarubicin B, isolated from the culture filtrate of a Streptomyces strain JA 2861, is a new quinone antibiotic. The compound was isolated as an orange crystalline powder, mp 282 approximately 284 degrees C. In vitro sarubicin B was found to inhibit Gram-positive bacteria. It was not active against Gram-negative microorganisms.
2. Sarubicinols A-C, Cytotoxic Benzoxazoles from a Streptomyces
Han Wang, Huan Qi, Shao-Yong Zhang, Wen-Shuai Song, Li-Qin Zhang, Wen-Sheng Xiang, Ji-Dong Wang J Nat Prod. 2022 Apr 22;85(4):1167-1173. doi: 10.1021/acs.jnatprod.1c00820. Epub 2022 Feb 25.
A chemical investigation of Streptomyces sp. Hu186 afforded two known quinone antibiotics, sarubicin A (1) and sarubicin B (2), together with three unusual variants, sarubicinols A-C (3-5), and two new 1,4-naphthoquinone metabolites, sarubicin B1 (6) and sarubicin B2 (7). Compounds 3-5 possess a rare 2-oxabicyclo [2.2.2] substructure and a benzoxazole ring system. Their structures were elucidated using 1D and 2D nuclear magnetic resonance and high-resolution electrospray ionization mass spectrometry data. The absolute configurations of the side-chain moieties in 4 and 5 were solved by electronic circular dichroism calculations. Compounds 1-7 showed moderate cytotoxic activity against four tumor cell lines.
