摘要

从海绵 Plakinastrella sp.的有机提取物中纯化出了两种环过氧化物，即 plakortides V (1) 和 W (2)。通过对 R- 或 S-MTPA Mosher 酯的 1H NMR 光谱数据进行比较分析，确定了 1,2-二恶烷分子的三个立体中心的绝对构型为 3R,4S,6S。在 NCI-60 细胞毒性试验中，化合物 1 和 2 对 LOX IMVI（黑色素瘤）、UO-31（肾癌）和 HL-60 (TB)（白血病）细胞株具有很强的细胞毒性活性。

Structure elucidation, absolute configuration, and biological evaluation of cyclic peroxides from the sponge Plakinastrella sp.

Two cyclic peroxides, plakortides V (1) and W (2) were purified from the organic extract of the sponge Plakinastrella sp. Their planar structures were established based on extensive NMR and MS analysis and the absolute configurations of the three stereogenic centers of the 1,2-dioxane moiety were determined to be 3R,4S,6S by comparative analysis of the ¹H NMR spectral data of the R- or S-MTPA Mosher esters. Compounds 1 and 2 exhibited potent cytotoxic activity against LOX IMVI (melanoma), UO-31 (renal), and HL-60 (TB) (leukemia) cell lines in the NCI-60 cytotoxicity assay.
