  Discovery of 4,6-bis(benzyloxy)-3-phenylbenzofuran as a novel Pin1 inhibitor to suppress hepatocellular carcinoma via upregulating microRNA biogenesis

  摘要：

  Peptidyl-prolyl cis-trans isomerase NIMA-interacting 1 (Pin1) participates in diverse cancer-associated signaling pathways, playing an oncogenic role in multiple human cancers, including hepatocellular carcinoma (HCC). Our recent works clarify that Pin1 modulates miRNAs biogenesis by interacting with ERK-phosphorylated exportin-5 (XPO5) and changing XPO5 conformation, giving a potential target for HCC treatment. Herein, we discover 4,6-bis(benzyloxy)-3-phenylbenzofuran (TAB29) as a novel Pin1 inhibitor that targets Pin1 PPIase domain. TAB29 potently inhibits Pin1 activity with the IC50 value of 874 nM and displays an excellent selectivity toward Pin1 in vitro. Cell-based biological evaluation reveals that TAB29 significantly suppresses cell proliferation of HCC cells through restoring the nucleus-to-cytoplasm export of XPO5 and upregulating mature miRNAs expression. Collectively, this work provides a promising small molecule lead compound for Pin1 inhibition, highlighting the therapeutic potential of miRNA-based treatment for human cancers.

  通过铜催化的 Friedel-Crafts 烷基化反应对映选择性合成氮-氮联芳基阻转异构体

  摘要：

  含有基序的氮-氮键在天然产物和生物活性化合物中无处不在。然而，由围绕 N-N 键的受限旋转引起的阻转异构在很大程度上被忽视了。在这里，我们描述了一种通过 Cu-双恶唑啉催化的 Friedel-Crafts 烷基化反应对 N-N 联芳基阻转异构体进行首次对映选择性合成的方法。通过去对称化和动力学拆分，以高产率高效制备了多种轴向手性 N-N 双氮杂杂环化合物，并具有优异的对映选择性。加热实验表明轴向手性双氮杂杂环产物具有高旋转势垒。

  suggested betaine as a common intermediate in alcoholic solution. Further reaction then involves rearrangement to give the vinyloxyphosphonium species (and hence the Perkow product) or protonation followed by dealkylation to give the α-hydroxyphosphonate. Evidence for the possible formation of dehalogenated ketone via solvolysis of the α-hydroxyphosphonium intermediate is also presented.
