    Development of Oleanane-Type Triterpenes as a New Class of HCV Entry Inhibitors
    摘要:
    Development of hepatitis C virus (HCV) entry inhibitors represents an emerging approach that satisfies a tandem mechanism for use with other inhibitors in a multifaceted cocktail. By screening Chinese herbal extracts, oleanolic acid (OA) was found to display weak potency to inhibit HCV entry with an IC50 of 10 mu M. Chemical exploration of this triterpene compound revealed its pharmacophore requirement for blocking HCV entry, rings A, B, and E, are conserved while ring D is tolerant of some modifications. Hydroxylation at C-16 significantly enhanced its potency for inhibiting HCV entry with IC50 at 1.4 mu M. Further modification by conjugation of this new lead with a disaccharide at 28-COOH removed the undesired hemolytic effect and, more importantly, increased its potency by similar to 5-fold (54a, IC50 0.3 mu M). Formation of a triterpene dimer via a linker bearing triazole (70) dramatically increased its potency with IC50 at similar to 10 nM. Mechanistically, such functional triterpenes interrupt the interaction between HCV envelope protein E2 and its receptor CD81 via binding to E2, thus blocking virus and host cell recognition. This study establishes the importance of triterpene natural products as new leads for the development of potential HCV entry inhibitors.

    摘要:
    流感病毒是一种主要的人类病原体,会导致每年的流行病和偶发的大流行病。近来,已显示植物来源的五环三萜烯通过有效防止病毒体附着于宿主细胞而充当高效的抗病毒剂。在本报告中,我们将唾液酸与齐墩果酸(OA)(具有广泛的抗病毒进入活性的天然产物),以及其他三个类似物棘皮酸(EA),熊果酸(UA)和桦木酸(BA)共轭。合成了总共24种具有不同接头的共轭唾液酸和五环三萜衍生物,并评估了其在MDCK细胞培养物中对A / WSN / 33(H1N1)流感病毒的抗病毒活性。最有效的化合物的IC 50为41.2μM。添加时间,血凝抑制(HI),表面等离振子共振(SPR)和分子对接测定表明,化合物20a通过阻止流感病毒血凝素(HA)蛋白与宿主细胞结合而充当流感病毒进入抑制剂。

    Dipsacus asperoides, were found to have anti‐HCV entry properties. The major issue for members of this type of triterpene is their low water solubility. In this study, a series of new water‐soluble triazole‐bridged β‐cyclodextrin (CD)–pentacyclic triterpene conjugates were synthesized via click chemistry. Thanks to the attached β‐CD moiety, all synthesized conjugates showed lower hydrophobicity (Alog P) than
    在我们以前的研究中,发现从双歧双曲霉中分离出的齐墩果酸(OA)和棘皮囊藻酸(EA)具有抗HCV进入特性。这类三萜成员的主要问题是其低溶性。在这项研究中,通过点击化学合成了一系列新的溶性三唑桥连的β-环糊精(CD)-五环三萜共轭物。由于连接了β-CD部分,所有合成的缀合物均显示出较低的疏性(Alog  P)比其母体化合物。几种缀合物表现出中等的抗HCV进入活性。除过O-甲基化的β-CD-五环三萜共轭物外,基于对HeLa,HepG2,MDCK和293T细胞进行的alamarBlue分析,所有其他共轭物均未显示细胞毒性。更有趣的是,这些缀合物的溶血活性在引入β-CD后消失了。容易获得结合了β-CD和五环三萜类化合物性质的结合物,可能会提供一种获得新型抗HCV进入抑制剂的方法。

In our continuing efforts to identify novel potential anti-HCV entry inhibitors, a series of water-soluble triazole-bridged α-cyclodextrin-pentacyclic triterpene conjugates were easily synthesized with moderate to good yields. These novel compounds were fully identified and characterized by 1D and 2D NMR spectroscopy

Modification of C-4 of sialic acid can lead to derivatives with potent anti-influenza activities, such as Zanamivir. Herein, we described the synthesis of novel C-4 modified sialic acid derivatives by conjugation with naturally derived pentacyclic triterpenes, an active ingredient of traditional Chinese medicine
