Reference Reading

1. Two sulfur-containing ansamycin antibiotics from Streptomyces albolongus
S Tanida, S Shinagwa, M Takizawa, T Takahashi, S Harada, T Hasegawa Experientia. 1986 Oct 15;42(10):1167-70. doi: 10.1007/BF01941296.
Two sulfur-containing ansamycin antibiotics were isolated from the culture broth of Streptomyces albolongus C-46366; the major one was identical with awamycin and the minor one was a new ansamycin antibiotic, ansathiazin. Their structures were elucidated from their reactions and spectroscopic analyses. These antibiotics were active against gram-positive bacteria, acid-fast bacteria and a protozoan.
2. A new antitumor antibiotic, awamycin
I Umezawa, H Oka, K Komiyama, K Hagiwara, S Tomisaka, T Miyano J Antibiot (Tokyo). 1983 Sep;36(9):1144-9. doi: 10.7164/antibiotics.36.1144.
A new antibiotic, awamycin, was isolated from the culture broth of Streptomyces sp. No. 80-217. It appeared to belong to the quinone indicator group from results of physicochemical studies and has the empirical formula C38H49NO12S. This antibiotic possessed antibacterial and antitumor activities against Gram-positive bacteria and experimental murine tumors. The antibiotic also showed direct cytotoxic activity against HeLa cells in vitro.
