  呋喃喹啉衍生物的新合成

  摘要：

  7-acyloxyquinolin-2-one 和 7-acyloxy-2-chloroquinoline 衍生物及其类似物的 Fries 重排为呋喃喹啉衍生物合成的新途径提供了有用的中间体。介绍 首先，已知呋喃香豆素、补骨脂素和当归衍生物具有很高的光生物活性。然而，它们也表现出一些负面的副作用。例如，紫外光下呋喃香豆素的高活性提供了 DNA 交联，从而可能导致癌症疾病。已经发现，内酯环中除氧原子外还含有其他杂原子的呋喃香豆素类似物没有这些副作用。因此，呋喃喹啉衍生物（尤其是呋喃喹啉-2-one 衍生物）作为呋喃香豆素类似物备受关注。文献中有一些呋喃喹啉-2-一衍生物合成 5 ' 6 的方案。在研究呋喃香豆素杂类似物制备的新方法时，我们发现乙酰氧基喹啉衍生物的 Fries 重排是获得最终呋喃喹啉的关键中间体的有用反应。我们早先已经成功地在许多呋喃香豆素的合成中使用了 Fries 重排。例如，用过量的氯化铝处理

  methylbenzofuro[4,5-c]-2,6-naphthyridin-5(6H)-ones were synthesized, first building the pyridine nucleus on the appropriated quinolin-2-ones, and then condensing the furan ring on the preconstituted benzonaphthyridinones. The benzo[c][2,6]naphthyridinic nucleus was also interesting for its known pharmacological properties, as well as intermediate for the synthesis of natural product analogues.

  A new series of hybrid 2-Quinolinone derivatives were synthesized and structurally proved using spectral and elemental analyses data. All the prepared compounds were tested for their in vitro cytotoxic activity against MCF-7 cell line. Compounds 6 and 8 showed potent anticancer activity, which were comparable to Doxorubicin as reference compound. While compound 3 was comparable to cisplatin. Cell cycle analysis of compounds 6 and 8 showed cell cycle arrest at S and G2/M phases of the cycle and induced apoptosis at pre-G1 phase. DNA synthesis inhibitory activity demonstrated that compound 6 showed equipotent activity to Doxorubicin. The extent of apoptosis was also determined using Annexin V-FITC assay. In addition, compounds 6 and 8 increase the activation of effector caspase 3 by four fold more than untreated control. On the other hand, the localization of compounds 3, 6 and 8 were found in the nucleus.

  We have studied earlier a membrane bound novel enzyme Acetoxy Drug: protein transacetylase identified as Calreticulin Transacetylase (CRTAase) that catalyzes the transfer of acetyl groups from polyphenolic acetates (PAs) to the receptor proteins and thus modulating their biological activities. In this communication, we have reported for the first time that acetoxy quinolones are endowed with antiplatelet action by virtue of causing CRTAase catalyzed activation of platelet Nitric Oxide Synthase (NOS) by way of acetylation leading to the inhibition of ADP/Arachidonic acid (AA)-dependent platelet aggregation. The correlation of specificity of platelet CRTAase to various analogues of acetoxy quinolones with intracellular NO and consequent effect on inhibition of platelet aggregation was considered crucial. Among acetoxy quinolones screened, 6-AQ (4-methyl-2-oxo-1,2-dihydroquinolin-6-yl acetate/6-acetoxyquinolin-2-one, 22) was found to be the superior substrate to platelet CRTAase and emerged as the most active entity to produce antiplatelet action both in vitro and in vivo. 6-AQ caused the inhibition of cyclooxygenase-1 (Cox-1) resulting in the down regulation of thromboxane A2 (TxA2) and the inhibition of platelet aggregation. Structural modi. cation of acetoxy quinolones positively correlated with enhancement of intracellular NO and antiplatelet action. (C) 2010 Elsevier Ltd. All rights reserved.
