  Design and synthesis of novel pyranone-based insulin sensitizers exhibiting in vivo hepatoprotective activity

  摘要：

  使用噻唑烷二酮（TZD）类胰岛素增敏剂治疗后会出现严重的肝脏和心血管并发症，这极大地阻碍了以 TZD 为基础、具有高亲和力和选择性结合的过氧化物酶体增殖物激活受体激动剂新药的开发。本研究旨在设计新的降糖药物，通过部分脂肪生成促进胰岛素敏感性，并显示出有益的保肝活性。研究结果表明，在筛选出的 40 个化合物中，3 个新型吡喃酮类化合物在 10 μM 剂量下可促进 3T3-L1 细胞系中的前脂肪细胞分化为脂肪细胞。这些化合物具有胰岛素增敏作用，能显著增加葡萄糖摄取量，并能逆转胰岛素抵抗。与标准保肝剂水飞蓟素相比，剂量为 20 毫克/千克-1 的这些化合物能明显防止硫代乙酰胺诱导的血清生化肝毒性变化，还能改善瑞士小鼠急性肝损伤后肝组织的组织病理学改变。

  Imaging and Quantitative Detection of Lipid Droplets by Yellow Fluorescent Probes in Liver Sections of Plasmodium Infected Mice and Third Stage Human Cervical Cancer Tissues

  摘要：

  与脂质异常相关的疾病的诊断和预后是极其重要的领域。在此方向上，通过结合存在于生物膜中的磷脂磷脂酰乙醇胺的乙醇胺头部基团，设计并合成了基于荧蒽的黄色荧光探针（FLUN-550、FLUN-552、FLUN-547）。由于其独特光物理特性和水溶性，这些探针成功用于前脂肪细胞和利什曼原虫前鞭毛体中脂滴的染色。此外，利用荧光探针FLUN-550和FLUN-552，我们成功成像并定量检测了恶性疟原虫耐多药小鼠肝切片中脂质过量积累（3至4倍）以及第三阶段人宫颈癌组织切片中的脂质积累（1.5至2倍），相较于正常组织。据我们所知，这是首次报道用于成像和定量检测人宫颈癌组织中脂滴的黄色荧光探针。这些新型黄色荧光脂质探针（FLUN-550和FLUN-552）在宫颈癌患者的诊断中展现出巨大潜力。

  The present invention relates to novel donor-acceptor fluoranthenes of the general formula I which can be used potentially in developing fluorescent probes, and a process of preparing said novel compounds. More particularly, the present invention relates to amine or alkoxy group as donor and nitrile group as an acceptor attached to the fluoranthene skeleton, processes for preparing the said compounds and their uses as fluorescent probes in chemical and biological sciences such as cell imaging applications, diagnostics, fluorescent tags and other useful applications. The compounds are prepared by reacting 2H-pyran-2-ones in isolated or rigid conformations with cyclic ketones containing methylene carbonyl moiety in the presence of a base in an organic solvent.

  The diagnosis and prognosis of the disease associated with lipid irregularity are areas of extreme significance. In this direction, fluoranthene based yellow fluorescent probes (FLUN-550, FLUN-552, FLUN-547) were designed and synthesized by conjugating the ethanolamine headgroup of the phospholipid phosphatidyl-ethanolamine present in biological membranes. Owing to unique photophysical properties and aqueous compatibility, these probes were successfully employed for staining lipid droplets (LDs) in preadipocytes and Leishmania donovani promastigotes. Furthermore, using the fluorescent probes FLUN-550 and FLUN-552 we successfully imaged and quantitatively detected the excess accumulation of lipids in a liver section of Plasmodium yoelii MDR infected mice (3- to 4-fold) and the tissue sections of third stage human cervical cancer patients (1.5- to 2-fold) compared to normal tissues. To the best of our knowledge, this is the first report of yellow fluorescent probes for imaging and quantitative detection of LDs in human cervical cancer tissues. These new yellow fluorescent lipid probes (FLUN-550 and FLUN-552) showed great potential for diagnosis of cervical cancer patients.

  Serious hepatic and cardiovascular complications after treatment with the thiazolidinedione (TZD) class of insulin sensitizers have significantly retarded the advancement of new TZD-based peroxisome proliferator-activated receptor agonists that bind with high affinity and selectivity. The aim of the present study is to design new antihyperglycemic agents that promote insulin sensitivity through partial adipogenesis as well as demonstrate beneficial hepatoprotective activity. The results indicated that among forty screened compounds, three of the novel pyranones at a dose of 10 μM increased the preadipocyte differentiation into adipocytes in 3T3-L1 cell lines. They showed an insulin-sensitizing effect by significantly increasing the glucose uptake and exhibited insulin resistance reversal. These compounds at a dose of 20 mg kg−1 significantly protected against thioacetamide-induced hepatotoxic changes in the serum biochemistry as compared to standard hepatoprotectant silymarin and also ameliorated the histopathological alterations in the liver tissues after acute liver injury in Swiss mice.
