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, 1Oa, 11-tetrahydroxy-3, 8-dimethyl-l-propyl-6aH(S)-pyrano[2'', 3'': 5', 4]furo[2', 3': 5, 6]azuleno[2, 3-c]pyridine-5, 13-di one (1) by single crystal X-ray analysis of a suitable derivative. A second pigment, B, is probably structurally closely related.
Streptomyces echinoruber sp.其主要成分鲁勃罗龙已被鉴定为 8(R),9(R),10(S),10a(R)-四氢-9,10,1Oa,11-四羟基-3,8-二甲基-l-丙基-6aH(S)-吡喃并[2'',3'':5',4]呋喃并[2',3':5,6]氮杂并[2,3-c]吡啶-5,13-二酮 (1) 的合适衍生物的单晶 X 射线分析。第二种色素 B 可能在结构上与之密切相关。
