Ten isoprenylated flavonoids were isolated from 95% ethanol extraction of Artocarpus heterophyllus, with a combination of various chromatographic approaches, including ODS, MCI, CHP-20 P, Sephadex LH-20 and high performance liquid chromatography. On the basis of physic-chemical characters and spectroscopic data analysis, these compounds were identified as artoheteroid E (1), cycloheterophyllin (2), artelastoxanthone (3), artoindonesianin Q (4), cudraflavone C (5), 8-(γ, γ-dimethylallyl)-5, 2', 4'-trihydroxy-7-methoxyflavone (6), kuwanon T (7), 6-(3-methylbut-2-enyl) apigenin (8), 5, 7, 2', 4'-tetrahydroxy-6-(3-methylbut-3-enyl) flavone (9), albanin A (10). Among them, compound 1 is a new one, while compounds 2-4 were isolated for the first time from the plant of Artocarpus heterophyllus. All isolated compounds were screened for their inhibitory abilities against cathepsin K. Of them, compounds 3-5, 7 and 10 showed inhibitory effects with the IC50 values of 0.9, 1.6, 4.5, 24.5 and 63.5 μmol·L-1, respectively.

采用ODS、MCI、Sephadex LH-20、半制备HPLC等柱色谱技术对波罗蜜(桑科波罗蜜属)根的95%乙醇提取物进行了化学成分研究。从中分离得到了10个异戊烯基黄酮类成分,根据理化性质和波谱数据鉴定为artoheteroid E(1)、cycloheterophyllin(2)、artelastoxanthone(3)、artoindonesianin Q(4)、柘树黄酮C(5)、8-(γγ-dimethylallyl)-5,2',4'-trihydroxy-7-methoxyflavone(6)、桑皮酮T(7)、6-(3-methylbut-2-enyl)apigenin(8)、5,7,2',4'-四羟基-6-异戊烯基黄酮(9)和albanin A(10)。其中化合物1为新化合物,2~4为首次从该植物中分离得到。所有的化合物进行了抑制组织蛋白酶K(cathepsin K,CatK)活性筛选,其中化合物3~5710对CatK具有不同程度的抑制作用,其IC50值分别为0.9、1.6、4.5、24.5、63.5μmol·L-1

Ten isoprenylated flavonoids were isolated from 95% ethanol extraction of Artocarpus heterophyllus, with a combination of various chromatographic approaches, including ODS, MCI, CHP-20 P, Sephadex LH-20 and high performance liquid chromatography. On the basis of physic-chemical characters and spectroscopic data analysis, these compounds were identified as artoheteroid E (1), cycloheterophyllin (2), artelastoxanthone (3), artoindonesianin Q (4), cudraflavone C (5), 8-(γ, γ-dimethylallyl)-5, 2', 4'-trihydroxy-7-methoxyflavone (6), kuwanon T (7), 6-(3-methylbut-2-enyl) apigenin (8), 5, 7, 2', 4'-tetrahydroxy-6-(3-methylbut-3-enyl) flavone (9), albanin A (10). Among them, compound 1 is a new one, while compounds 2-4 were isolated for the first time from the plant of Artocarpus heterophyllus. All isolated compounds were screened for their inhibitory abilities against cathepsin K. Of them, compounds 3-5, 7 and 10 showed inhibitory effects with the IC50 values of 0.9, 1.6, 4.5, 24.5 and 63.5 μmol·L-1, respectively.

波罗蜜(Artocarpus heterophyllus Lam.)为桑科波罗蜜属植物, 以其硕大的果实而著称, 又名“树婆罗”、“牛肚子果”、“蜜冬瓜”等, 主要分布于亚洲的热带及亚热带地区, 在我国东南和华南的福建、台湾、广东、广西及海南等省多有栽培。《本草纲目》载, 波罗蜜“甘微酸, 平, 无毒”, 具有“止渴解烦, 醒酒, 益气”的功效[1]。波罗蜜的幼果、树汁、叶、树皮在当地民间入药, 用于消肿解毒、跌打损伤、肺热咳嗽、产妇无乳汁、食欲不振、饮酒过度等[2]。国内外对波罗蜜的化学成分研究表明, 其主要含有黄酮[3]、二苯乙烯[4]、2-芳基苯并呋喃[5]等酚性成分, 具有细胞毒[6]、抗炎[7]、抗氧化[8]、抗中性粒细胞呼吸爆发[9]以及抑制酪氨酸酶[10]的活性。组织蛋白酶K (cathepsin K, CatK)是治疗骨质疏松症的一个新型靶点, 近年来证明其抑制剂对骨质疏松症有明显的治疗效果[11, 12]。本课题组前期发现波罗蜜的乙醇提取物对组织蛋白酶K具有一定的抑制效果, 并从中分离一些活性单体[13, 14]。作为该工作的延续, 本课题组继续对波罗蜜的乙醇提取物进行分离, 获得了10个异戊烯基取代的黄酮类化合物(图 1), 分别鉴定为artoheteroid E (1)、cycloheterophyllin (2)、artelastoxanthone (3)、artoindonesianin Q (4)、柘树黄酮C (5)、8-(γ, γ-dimethylallyl)-5, 2', 4'-trihydroxy-7-methoxyflavone (6)、桑皮酮T (7)、6-(3-methylbut-2-enyl) apigenin (8)、5, 7, 2', 4'-四羟基-6-异戊烯基黄酮(9)和albanin A (10)。其中, 化合物1为新化合物, 化合物2~4为首次从该植物中分离得到。所有分离的化合物进行了抑制CatK活性筛选, 其中, 化合物3~5710对CatK具有不同程度的抑制作用, 其IC50值分别为0.9、1.6、4.5、24.5、63.5 µmol·L-1
化合物1为黄色无定形粉末(丙酮)。HR-ESI-MS给出准分子离子峰m/z 449.161 1 [M-H]- (计算值为449.160 6), 确定其分子式为C26H26O7。红外光谱(IR)显示其结构中存在羟基(3 447 cm-1)、甲基(2 927 cm-1)、羰基(1 654 cm-1)、苯环(1 610 cm-1)等特征信号峰。紫外光谱(UV)显示在262、315及371 nm处有特征性吸收。1H NMR谱(表 1)显示了一个与羰基螯合的羟基δH 13.20 (1H, s, HO-5); 2个间位耦合芳香质子信号δH 6.27 (1H, br s, H-6)和6.69 (1H, br s, H-8);一组典型的γ, γ二甲基烯丙基侧链取代基的质子信号δH 3.33 (2H, d, J = 7.1 Hz, H-16)、5.19 (1H, t, J = 7.1 Hz, H-17)、1.76 (3H, s, H-19)和1.67 (3H, s, H-20)[15, 16]; 一个ABX自旋耦合体系δH 2.35 (1H, t, J = 15.4 Hz, Ha-11)、3.19 (1H, dd, J = 15.2, 7.1 Hz, Hb-11)和3.38 (1H, dd, J = 15.5, 7.1 Hz, H-12);两个甲基δH 1.35 (3H, s, H-14)和1.64 (3H, s, H-15);一个甲氧基δH 4.01 (3H, s, MeO-4')。化合物11H NMR谱数据与已知化合物artoheteroid C (图 1)[13]非常相似。两者氢谱差异主要体现在:化合物1的H-3'信号消失, 而多出了一组归属于γ, γ-二甲基烯丙基的质子信号。这提示, 化合物1的C-3'位发生了一个γ, γ-二甲基烯丙基型的侧链取代。分析113C NMR数据(表 1)并利用HMQC谱对其碳信号进行归属, 支持了这个推测:与artoheteroid C相比, 化合物1多出了5个碳信号δC 23.7 (C-16)、123.8 (C-17)、131.4 (C-18)、17.9 (C-19)和25.9 (C-20), 这是γ, γ-二甲基烯丙基型异戊二烯取代基的典型碳信号。化合物1的HMBC谱(图 2)显示, H-16与C-2'、C-3'、C-4'的相关, H-17与C-3'的相关。这进一步证实了γ, γ-二甲基烯丙基侧链取代位于C-3'。甲氧基质子信号δH 4.01与C-3'的HMBC相关证明了甲氧基取代在C-4'位。化合物1具有旋光活性, 比旋光值{[α]D25-3.5 (c 0.1, MeOH)}与来自同种植物的artoheteroid C的比旋光值{[α]D25-2.4 (c 0.3, MeOH)}[13]相近, 提示他们的C-12具有相同的立体构型R。因此, 化合物1鉴定为图 1所示的结构, 它是一个新的异戊烯基黄酮, 命名为artoheteroid E。
对所有分离的化合物进行了组织蛋白酶K活性评价。如表 2所示, 化合物3~5710显示不同程度的抑制作用。观察这些活性化合物的结构可发现初步的构效规律: B环上C-2'/C-5' (34)或C-2'/C-4' (5, 7, 10)的二游离酚羟基取代及C环C-3位置的异戊烯基取代对于活性是必须的; B环2', 5'-二羟基取代型化合物(34)的活性强于2', 4'-二羟基取代型化合物(5710)。
