摘　　要：对采自中国南海西沙群岛的简易扁板海绵(Plakortis simplex)进行化学成分研究,运用LC-MS法结合HPLC法高效追踪分离和富集其萜酚类化合物,并采用MTT法和荧光素酶双报告基因检测法分别检测萜酚类化合物的抗肿瘤活性和抗炎活性。结果表明,从该海绵的正丁醇萃取物中共富集和分离了8个已知的萜酚类化合物,分别为Plakordiol A(1)、Plakordiol B(2)、Plakordiol C(3)、Plakordiol D(4)、(7R,10R)-Hydroxycurcudiol(5)、(7R,10S)-Hydroxycurcudiol(6)、(7R*,10R*)-Abolene(7)和(7R*,10S*)-Abolene(8),为4对差向异构体。在20μmol/L浓度下,8个萜酚类化合物均对人乳腺癌细胞MCF-7表现出一定的细胞毒活性,其中Plakordiol A(1)和Plakordiol C(3)对9-顺视黄酸诱导的RXRα的转录具有一定的抑制活性,与模型组相比存在显著差异(P<0.05或P<0.01),而Plakordiol D(4)促进9-顺视黄酸激活RXRα的转录活性,与模型组相比存在显著差异(P<0.01);Plakordiol A(1)可抑制TNF-α诱导的NF-κB的激活,且与模型组相比存在显著差异(P<0.05)。The chemical composition of Plakortis simplex collected from Xisha Islands in the South China Sea was studied.The terpene phenolic compounds from Plakortis simplex were tracked and enriched efficiently by LC-MS combined with HPLC.The antitumor and anti-inflammatory activities of terpene phenolic compounds were detected by MTT assay and luciferase double reporter gene assay respectively.The results showed that eight known terpene phenolic compounds,Plakordiol A(1),Plakordiol B(2),Plakordiol C(3),Plakordiol D(4),(7R,10R)-Hydroxycurcudiol(5),(7R,10S)-Hydroxycurcudiol(6),(7R*,10R*)-Abolene(7)and(7R*,10S*)-Abolene(8),which were four pairs of differential isomers,were enriched and isolated from the n-butanol extract of the sponge.All the compounds showed cytotoxicity against human breast cancer MCF-7 cells at the concentration of 20 mmol/L.Plakordiol A(1)and Plakordiol C(3)showed inhibitory activity against the transcription of RXRαinduced by 9-cis-retinoic acid,with significant differences compared to the model group(P<0.05 or P<0.01).While Plakordiol D(4)promoted the transcriptional activity of RXRα,with significant differences compared with the model group(P<0.01).Plakordiol A(1)inhibited the activation of NF-κB induced by TNF-αand had significant differences compared to the model group(P<0.05).
