  Inhibitory Effects of Constituents from Cynomorium songaricum and Related Triterpene Derivatives on HIV-1 Protease.

  摘要：

  从锁阳（Cynomorium songaricum RUPR.）茎的CH2Cl2和MeOH提取物中，分离得到了熊果酸及其丙二酸氢化物，它们是人类免疫缺陷病毒1型（HIV-1）蛋白酶的抑制剂，其半数抑制浓度（IC50）分别为8和6微摩尔。在合成的各种相关三萜二羧酸半酯中，对于熊果酸、齐墩果酸和白桦脂酸等三萜类化合物，抑制活性倾向于按草酰、丙二酰、琥珀酰和戊二酰半酯的顺序增加。其中，戊二酰半酯显示出最强的抑制作用，IC50为4微摩尔。从锁阳茎的水提取物中，还发现了由表儿茶素构成扩展单元的黄烷-3-醇聚合物，它们也是HIV-1蛋白酶的强效抑制剂。

  Anticancer Activity of 3-O-Acylated Betulinic Acid Derivatives Obtained by Enzymatic Synthesis

  摘要：

  一种简便高效的策略通过酶合成方法制备了白桦酸的各种酐酯。该方法涉及在有机溶剂中使用酐作为酰化剂，通过脂肪酶催化白桦酸的酰化反应。采用了固定在丙烯酸树脂上的南极假丝酵母脂肪酶（Novozym 435）作为生物催化剂。通过这一步骤成功获得了几种3-O-酰基白桦酸衍生物。随后，评估了白桦酸及其3-O-酰化衍生物对人肺腺癌（A549）和人卵巢癌（CAOV3）细胞系的体外抗癌活性。3-O-戊二酰白桦酸、3-O-乙酰白桦酸和3-O-琥珀酰白桦酸对A549癌细胞系的IC50值小于10微克/毫升，并且显示出比白桦酸更强的细胞毒性。在卵巢癌细胞系中，所有制备的白桦酸衍生物的细胞毒性均弱于白桦酸。

  lupane-type triterpenoic acid derivatives were synthesized and evaluated for their inhibitory activity against HIV-1 replication in acutely infected H9 cells, based on the fact that betulinic acid (1) and dihydrobetulinic acid (9) were identified as anti-HIV agents. Among the derivatives, 3-O-(3',3'-dimethylsuccinyl)-betulinic acid (3) and 3-O-(3',3'-dimethylsuccinyl)-dihydrobetulinic acid (11) both demonstrated

  From CH2Cl2 and MeOH extracts of the stems of Cynomorium songaricum RUPR. (Cynomoriaceae), ursolic acid and its hydrogen malonate were isolated as inhibitors of human immunodeficiency virus type 1 (HIV-1) protease, with 50% inhibitory concentrations (IC50) of 8 and 6 μM, respectively. Amongst various synthesized dicarboxylic acid hemiesters of related triterpenes, inhibitory activity tended to increase in the order of oxalyl, malonyl, succinyl and glutaryl hemiesters, for triterpenes such as ursolic acid, oleanolic acid and betulinic acid. The most potent inhibition was observed for the glutaryl hemiesters, with an IC50 of 4 μM.From the water extract of the stems of C. songaricum, flavan-3-ol polymers, consisting of epicatechin as their extender flavan units, were also found to be potent inhibitory principles against HIV-1 protease.

  An easy and efficient strategy to prepare betulinic acid esters with various anhydrides was used by the enzymatic synthesis method. It involves lipase-catalyzed acylation of betulinic acid with anhydrides as acylating agents in organic solvent. Lipase from Candida antarctica immobilized on an acrylic resin (Novozym 435) was employed as a biocatalyst. Several 3-O-acyl-betulinic acid derivatives were successfully obtained by this procedure. The anticancer activity of betulinic acid and its 3-O-acylated derivatives were then evaluated in vitro against human lung carcinoma (A549) and human ovarian (CAOV3) cancer cell lines. 3-O-glutaryl-betulinic acid, 3-O-acetyl-betulinic acid, and 3-O-succinyl-betulinic acid showed IC50<10 μg/ml against A549 cancer cell line tested and showed better cytotoxicity than betulinic acid. In an ovarian cancer cell line, all betulinic acid derivatives prepared showed weaker cytotoxicity than betulinic acid.
