Studies on the isotetracenone antibiotics. III. A new isotetracenone antibiotic, grincamycin.
A complex of new isotetracenone group antibiotics was isolated from the cultured broth of Streptomyces sp. 2238-SVT4. It consisted of four related compounds, designated hatomarubigins A, B, C and D,

Three new antibiotics were obtained from the culture filtrate of an actinomycete identified as Streptomyces violaceolatus, and were named kerriamycins A, B and C, respectively. The structures of
Capoamycin, a New Isotetracenone Antibiotic
A new antibiotic was obtained from the cultured broth of an actinomycete identified as Streptomyces capoamus, and has been named capoamycin. The structure of capoamycin was elucidated by NMR spectral

Kerriamycins A, B and C, New Isotetracenone Antibiotics
TLDR
Three new antibiotics were obtained from the culture filtrate of an actinomycete identified as Streptomyces violaceolatus, and were named kerriamycins A, B and C, respectively, which inhibited the growth of Gram-positive bacteria and prolonged the survival periods of mice bearing Ehrlich ascites carcinoma.
