IV. Hatomarubigins A, B, C and D, new isotetracenone antibiotics effective against multidrug-resistant tumor cells.\nA 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, whose structures were elucidated by NMR spectral analysis including a variety of 2D techniques. They enhanced the cytotoxicity of colchicine against multidrug-resistant tumor cells.","tracks":[{"project":"PubmedHPO","denotations":[{"id":"T1","span":{"begin":527,"end":532},"obj":"HP_0002664"}],"attributes":[{"subj":"T1","pred":"source","obj":"PubmedHPO"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"PubmedHPO","color":"#e2ec93","default":true}]}]}}
