  Discovery of Naturally Occurring Aurones That Are Potent Allosteric Inhibitors of Hepatitis C Virus RNA-Dependent RNA Polymerase

  摘要：

  We have identified naturally occurring 2-benzylidenebenzofuran-3-ones (aurones) as new templates for non-nucleoside hepatitis C virus (HCV) RNA-dependent RNA polymerase (RdRp) inhibitors. The aurone target site, identified by site-directed mutagenesis, is located in thumb pocket I of HCV RdRp. The RdRp inhibitory activity of 42 aurones was rationally explored in an enzyme assay. Molecular docking studies were used to determine how aurones bind to HCV RdRp and to predict their range of inhibitory activity. Seven aurone derivatives were found to have potent inhibitory effects on HCV RdRp, with IC(50) below 5 mu M and excellent selectivity index (inhibition activity versus cellular cytotoxicity). The most active aurone analogue was (Z)-2-((1-butyl-1H-indo1-3-yl)methylene)-4,6-dihydroxybenzofuran-3(2H)-one (compound 51), with an IC(50) of 2.2 mu M. Their potent RdRp inhibitory activity and their low toxicity make these molecules attractive candidates as direct-acting anti-HCV agents.

  isoflavones, aurones have not been extensively explored as pancreatic lipase inhibitors. In this work, we studied the pancreatic lipase inhibitory potency of synthetic aurone derivatives. Thirty-six compounds belonging to four series (4,6-dihydroxyaurone, 6-hydroxyaurone, 4,6-dialkoxyaurone, and 6-alkoxyaurone) were designed and synthesized. Their in vitro inhibitory activities were determined by spectrophotometric

  橙酮是黄酮类化合物的一个小亚类。与查尔酮、黄酮和异黄酮等其他亚类不同，橙酮作为胰腺脂肪酶抑制剂尚未得到广泛研究。在这项工作中，我们研究了合成Aurone衍生物的胰腺脂肪酶抑制效力。设计并合成了属于四个系列（4,6-二羟基黄酮、6-羟基黄酮、4,6-二烷氧基黄酮和6-烷氧基黄酮）的36个化合物。通过分光光度法测定其体外抑制活性，并与槲皮素和奥利司他进行比较。具有长链（6-10 个碳）烷氧基取代基的烷氧基橙酮衍生物显示出更大的效力。其中，相对于槲皮素（IC50为86.98±3.859μM）和奥利司他（IC50为0.0334±0.0015μM），4,6-二烷氧基橙酮8表现出最高的抗胰腺脂肪酶活性（IC50为1.945±0.520μM）。荧光猝灭测量证实了烷氧基黄酮衍生物对胰腺脂肪酶的亲和力。动力学研究表明，8 通过竞争机制抑制脂肪酶（Ki 为 1.288 ± 0.282 µM）。分子对接结果阐明了
