The novel natural product xyloallenoide A, isolated from the marine mangrove endophytic fungus from the South China Sea, and its diastereoisomer xyloallenoide A1, which contain N‐methyl‐substituted amino acids, were synthesized. The absolute configurations of the amino acid units of xyloallenoide A were finally confirmed to be L‐Lys, Me‐D‐Val, and Me‐L‐Ala. This report represents a practical and attractive
合成了从南海的海洋红树林内生真菌中分离得到的新型天然产物xyloallenoide A及其非对映异构体xyloallenoide A1,其中包含N-甲基取代的氨基酸。xyloallenoide A的氨基酸单元的绝对构型最后确认为大号-Lys,ME- d -Val,和ME-大号-Ala。该报告代表了一种合成N-甲基取代的环三肽的实用且有吸引力的替代方法。在初步生物测定,合成xyloallenoide A显示对KB(边缘活动IC 50 = 9.6μ中号)和KBv200细胞细胞(IC 50= 10.3μ中号),和xyloallenoide A1反对KB和KBv200细胞的细胞无效。
