  Synthesis, docking and in vitro anticancer evaluation of some new benzopyrone derivatives

  摘要：

  The synthesis of some new 3-alkyl-7-hydroxy-4-methyl-8-substituted-1H-benzopyran-2-ones, 6-alkyl-7-methyl-2-substituted amino-5H-pyrano[6,5-e] benzoxazol-5-ones, 7-alkyl-8-methyl-3-substituted-2,6-dihydropyrano[6,5-f]-1,4-benzoxazin-6-ones, 7,8-disubstituted-3-ethyl-4-methyl-1H-benzopyran-2-ones and 3-alkyl-4-methyl-7-substituted-1H-benzopyran-2-ones were described. Fourteen compounds were selected by National Cancer Institute (NCI), Bethesda, and evaluated for their in vitro anticancer activity in the full NCI 60 cell lines panel assay by a single dose test. Compounds 4a, 18a, 18b and 23a were found to be broad-spectrum antitumors showing effectiveness toward numerous cell lines that belong to different tumor subpanels. Furthermore, docking studies were undertaken to gain insight into the possible binding mode of these compounds with the binding site of the casein kinase II (CK2) enzyme which is involved in cell survival and proliferation through a number of downstream effectors.

  of their resistance to antimicrobial agents are alarming issues worldwide and consistent efforts are being made to develop efficient antimicrobial agents. In this perspective, a series of novel ammonium and amide derivatives of pyranocoumarin and coumarin were synthesized and evaluated for their antimicrobial activity. Among them, six compounds exhibited significant activity against gram-positive bacteria

  A series of 7‐(2‐oxoalkoxy)coumarins have been synthesized by conjugating substituted 7‐hydroxycoumarins with different chloroketones. The anti‐inflammatory properties of 7‐(2‐oxoalkoxy)coumarins were studied in LPS‐induced inflammatory response in J774 macrophages. Western blot was used to determine the expression of iNOS and COX‐2, NO was determined by measuring its metabolite nitrite by Griess reaction

  通过将取代的7-羟基香豆素与不同的氯酮缀合，可以合成一系列7-（2-氧代烷氧基）香豆素。在L774诱导的J774巨噬细胞的炎症反应中研究了7-（2-氧代烷氧基）香豆素的抗炎特性。用Western印迹法测定iNOS和COX-2的表达，通过Griess反应测定其代谢产物亚硝酸盐测定NO，通过ELISA测定IL-6。在100μM的浓度下，有17种被研究的化合物抑制NO和IL-6的产生超过50％。最佳抑制剂的IC 50值对于化合物12为21μM/ 24μM（NO / IL-6），对于化合物20为30μM/ 10μM（NO / IL-6）。主要结果是，被7-（2-氧代烷氧基）取代可改善大多数研究的7-羟基香豆素的抗炎特性。
