摘要:

探究半边旗Pteris semipinnata 的化学成分及抗人类免疫缺陷病毒-1(HIV-1)活性。采用硅胶、MCI GEL CHP 20P、YMC GEL ODS-A-HG、Sephadex LH-20 凝胶柱色谱及重结晶等手段进行分离纯化,通过1H NMR、13 C NMR 和 ESI-MS 等波谱方法鉴定化合物的结构,通过HIV-1 蛋白酶测试盒对单体化合物进行体外抗HIV-1 活性评估。从黔产半边旗甲醇提取物中分离得到18 个化合物,分别鉴定为11β-hydroxy-15-oxo-ent-kauran-16-en-19-oic acid(1)、9-hydroxy-15-oxo-ent-kauran-16-en-19-oic acid(2)、11β-hydroxy-15-oxo-ent-kauran-19-oic acid(3)、7β-hydroxy-11β,16β-epoxyent-kauran-19-oic acid(4)、7β,9-dihydroxy-15-oxo-ent-kauran-16-en-19,6β-olide(5)、7β-hydroxy-15-oxo-ent-kauran-16-en- 19,6β-olide(6)、11β-hydroxy-15-oxo-ent-kauran-16-en-19-oic acid-19-β-D-glucoside(7)、9-hydroxy-15-oxo-ent-kaur-16-en- 19-oly-β-D-glucoside(8)、β-谷甾醇(9)、β-胡萝卜苷(10)、芹菜素(11)、5-葡萄糖芹菜苷(12)、香叶木素-7-O-β-D-葡萄糖苷(13)、琥珀酸(14)、1,21-二十一烷二醇(15)、正二十五烷(16)、正二十八烷(17)和熊果酸(18)。化合物8、11 ~ 17 为首次从半边旗中分离得到。活性筛选结果显示,化合物1、2、7、8 对HIV-1 蛋白酶均有一定的抑制活性,IC50 分别为2. 01 ± 0. 23、3. 61 ± 0. 56、3. 15 ± 0. 32、6. 82 ± 1. 02 μmol/ L,具有潜在抗HIV 活性。

Abstract:

This study aims to investigate the chemical constituents and anti-human immunodeficiency virus-1 (HIV-1) activity of Pteris semipinnata. The chemical constituents were isolated by silica,MCI GEL CHP 20P,YMC GEL ODS-A-HG,Sephadex LH-20 GEL column chromatography,and further purified by recrystallization. Their structures were determined on the basis of spectroscopic data ( 1H NMR,13C NMR,ESI-MS). The in vitro anti-HIV-1 activity of the monomeric compounds was evaluated by HIV-1 protease test kit. Eighteen compounds were isolated from methanol extracts of P. semipinnata,and they were identified as 11β-hydroxy-15-oxo-ent-kauran-16-en-19-oic acid (1),9-hydroxy-15-oxo-ent-kauran-16-en-19-oic acid (2),11β-hydroxy-15-oxo-ent-kauran-19-oic acid (3),7β-hydroxy-11β,16β-epoxy-ent-kauran-19-oic acid (4),7β,9-dihydroxy-15-oxo-ent-kauran-16-en-19,6β-olide (5),7β-hydroxy-15-oxo-ent-kauran-16-en-19,6β-olide (6),11β-hydroxy-15- oxo-ent-kauran-16-en-19-oic- acid-19-β-D-glucoside (7),9-hydroxy-15-oxo-ent-kauran-16-en-19-oly-β-D-glucoside (8),β- sitosterol (9), apigenin-5-O-β-D-glucopyranoside (10), apigenin (11), diosmetin 7-O-β-D-glucoside (12), daucosterol (13),1,21-heneicosanediol (14),pentacosane (15),succinic acid (16),n-octacosane (17),ursolic acid (18). Among them,compound 8,11-17 were isolated from of this species for the first time. The bioactivity results showed that compounds 1, 2,7 and 8 had relatively high anti-HIV-1 activities with IC50 values of 2. 01 ± 0. 23,3. 61 ± 0. 56,3. 15 ± 0. 32,6. 82 ± 1. 02 μmol/ L,respectively.
