explore the chemical constituents of Caribbean marine invertebrates, a family of 13 new diterpene glycosides, pseudopterosins P-Z (1-11) and seco-pseudopterosins H (12) and I (13), have been isolated from the organic extracts of two collections of the sea whip Pseudopterogorgia elisabethae procured near the Colombian Southwestern Caribbean Sea. The structures of compounds 1-13, including absolute stereochemistry
作为一项正在进行的探索加勒比海无脊椎动物化学成分的计划的一部分,已从加勒比海中分离出13个新的二萜糖苷,拟蝶呤PZ(1-11)和seco-pseudopterosins H(12)和I(13)家族。在哥伦比亚西南加勒比海附近采购的两种海鞭Pseudopterogorgia elisabethae的有机提取物。在全面的光谱分析,化学转化,比旋光和TLC色谱分析的基础上,提出了化合物1-13的结构,包括绝对立体化学。伪蝶呤Q(2)在体外抑制了由大肠杆菌脂多糖(LPS)激活的大鼠新生小胶质细胞生成的血栓烷B2(TXB2)(IC50 = 4.7 microM)和超氧阴离子(O2-)(IC50 = 11.2 microM)。相反,拟蝶呤P(1),U(6),V(7),W(8)和X(9)以及山co假单胞菌素H(12)和I(13)对TXB2和O2-的释放均显示出最小的影响。此外,一些新化合物还显示出强大的抗结核,抗病毒,抗疟疾和抗癌活性。
