  Design and discovery of flavonoid-based HIV-1 integrase inhibitors targeting both the active site and the interaction with LEDGF/p75

  摘要：

  HIV integrase (IN) is an essential enzyme for the viral replication. Currently, three IN inhibitors have been approved for treating HIV-1 infection. All three drugs selectively inhibit the strand transfer reaction by chelating a divalent metal ion in the enzyme active site. Flavonoids are a well-known class of natural products endowed with versatile biological activities. Their beta-ketoenol or catechol structures can serve as a metal chelation motif and be exploited for the design of novel IN inhibitors. Using the metal chelation as a common pharmacophore, we introduced appropriate hydrophobic moieties into the flavonol core to design natural product-based novel IN inhibitors. We developed selective and efficient syntheses to generate a series of mono 3/5/7/3'/4'-substituted flavonoid derivatives. Most of these new compounds showed excellent HIV-1 IN inhibitory activity in enzyme-based assays and protected against HIV-1 infection in cell-based assays. The 7-morpholino substituted 7c showed effective antiviral activity (EC50 = 0.826 mu g/mL) and high therapeutic index (TI > 242). More significantly, these hydroxyflavones block the IN-LEDGF/p75 interaction with low-to sub-micromolar IC50 values and represent a novel scaffold to design new generation of drugs simultaneously targeting the catalytic site as well as protein-protein interaction domains.

• An Efficient Method for the Glycosylation of Isoflavones
  作者：Nawaf Al-Maharik、Nigel P. Botting

  DOI：10.1002/ejoc.200800803

  日期：2008.11

  A new efficient, high-yielding glycosylation procedure is described for isoflavones, which employs 2,2,2-trifluoro-N-(p-methoxyphenyl)acetamidates as the glycosyl donors. This methodology was used to prepare the 7-O-glycosides of the three main isoflavones, daidzein, genistein and glycitein. The isoflavones were protected with hexanoyl groups which improved their solubility in organic solvents and

  异黄酮植物雌激素因其正面和负面的健康益处而受到当前的关注。然而，关于它们的吸收、代谢和生物利用度，仍有许多悬而未决的问题。该领域的研究需要获取异黄酮 7-O-葡萄糖苷（在植物中发现的形式）和 7-O-葡萄糖醛酸苷（它们是重要的哺乳动物代谢物）的样本。描述了一种新的高效、高产的异黄酮糖基化程序，它采用 2,2,2-三氟-N-（对甲氧基苯基）乙酰胺作为糖基供体。该方法用于制备三种主要异黄酮、黄豆苷元、染料木黄酮和黄豆黄素的 7-O-糖苷。异黄酮用己酰基保护，这提高了它们在有机溶剂中的溶解度并提高了反应效率。然后采用相同的方法合成类似的 7-O-葡糖苷酸。新的合成将为进一步的生物学研究提供大量这些化合物。(© Wiley-VCH Verlag GmbH & Co.

  A series of flavone-7-phosphoramidate derivatives were synthesized and tested for their antiproliferative activity in vitro against human hepatoma cell line HepG2 and human normal hepatic cell line L-O2. Compound 8d, 16d and 17d, incorporating the amino acid alanine, exhibited high inhibitory activity on HepG2 cell line with IC50 values of 9.0 mu mol/L, 5.5 mu mol/L and 6.6 mu mol/L. The introduction of acyl groups played a pivotal role in the selective inhibition toward human hepatoma HepG2 cells, except for compound 8a, 9a and 16b. Compound 8d, 16d and 17d could significantly induce G2/M arrest in HepG2 cells. Specially, Compound 16d could lead early apoptosis in HepG2 cells. (C) 2016 Elsevier Masson SAS. All rights reserved.
