目的 研究中国南海海绵Luffariella sp.的次生代谢产物及生物活性。方法 利用硅胶柱色谱、C-18反相柱色谱,半制备HPLC等方法对海绵提取物进行分离纯化,通过核磁共振、质谱、紫外、红外等波谱学技术,并结合文献理化数据,确定化合物的结构。对分离得到的化合物进行了NF-κB抑制活性评价实验。结果 分离鉴定了6个含α、β-不饱和γ–内酯环的二倍半萜类化合物,结构确定为Hippolide H (1)、Hippolide F (2)、Hippolide G (3)、Hippolide E (4)、6Z-neomanoalide (5)、6E-neomanoalide (6)。在NF-κB抑制活性评价实验中,化合物1、4、6 具有较好的NF-κB抑制活性。结论 南海海绵Luffariella sp.可代谢具有NF-κB抑制活性的二倍半萜类化合物。 |
English Summary: |
Objective To investigate the chemical constituents and bioactivity of the South China Sea sponge Luffariella sp. Methods The compounds were isolated and purified by using silica gel column chromatography, C-18 ODS and semi-preparative HPLC chromatography. Their structures were identified by 1D and 2D NMR、MS、UV、IR and comparison with the date of literatures. They were performed an NF-κB inhibitory activity evaluation test. Results Six sesterterpenoids with α、β–unsaturated–γ–lactone ring were isolated from the sponge. Their structures were identified as Hippolide H (1)、Hippolide F (2)、Hippolide G (3)、Hippolide E (4)、6Z-neomanoalide (5)、6E-neomanoalide (6). In the evaluation of NF–κB inhibitory activity, compounds 1, 4 and 6 showed good NF–κB inhibitory activity. |
