  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.

  Neoflavonoids as Inhibitors of HIV-1 Replication by Targeting the Tat and NF-κB Pathways

  摘要：

  已经制备并在体外评估了28种新黄酮类化合物对HIV-1的活性。抗病毒活性是在感染了带有荧光素酶报告基因的病毒克隆的MT-2细胞上进行评估的。HIV转录和Tat功能的抑制在稳定转染了HIV-LTR和Tat蛋白的细胞上进行测试。七种4-苯基色烯-2-酮衍生物显示出HIV转录抑制活性，但只有苯基色烯-2-酮10同时抑制了NF-κB并显示出抗Tat活性。化合物10、14和25在<25 μM的浓度下抑制了两种靶标中的HIV复制。这些合成的4-苯基色烯-2-酮的测定可能有助于研究此类化合物的抗HIV活性的某些方面，并可能作为设计更好抗HIV化合物的框架，从而导致潜在的抗HIV治疗药物的出现。

  Twenty-eight neoflavonoids have been prepared and evaluated in vitro against HIV-1. Antiviral activity was assessed on MT-2 cells infected with viral clones carrying the luciferase reporter gene. Inhibition of HIV transcription and Tat function were tested on cells stably transfected with the HIV-LTR and Tat protein. Seven 4-phenylchromen-2-one derivatives showed HIV transcriptional inhibitory activity but only the phenylchrome-2-one 10 inhibited NF-κB and displayed anti-Tat activity simultaneously. Compounds 10, 14, and 25, inhibited HIV replication in both targets at concentrations <25 μM. The assays of these synthetic 4-phenylchromen-2-ones may aid in the investigation of some aspects of the anti-HIV activity of such compounds and could serve as a scaffold for designing better anti-HIV compounds, which may lead to a potential anti-HIV therapeutic drug.
