Abstract
Streptomyces echinoruber sp. nov. produces several red pigments. The major component, rubrolone, has been identified as 8(R),9(R),10(S),10a(R)-tetrahydro-9,10,10a,11-tetrahydroxy-3,8-dimethyl-1-propyl-6aH(S)-pyrano[2",3":5',4]furo[2',3':5,6]azuleno[2,3-c]pyridine-5,13-dione (1) by single crystal X-ray analysis of a suitable derivative. A second pigment, B, is probably structurally closely related.
摘要
新种棘红链霉菌产生多种红色色素。主要成分鲁布罗酮，通过对一种合适衍生物的单晶X射线分析，已被鉴定为8(R),9(R),10(S),10a(R)-四氢-9,10,10a,11-四羟基-3,8-二甲基-1-丙基-6aH(S)-吡喃并[2",3":5',4]呋喃并[2',3':5,6]薁并[2,3-c]吡啶-5,13-二酮(1)。第二种色素B在结构上可能与之密切相关。
