  Antimitotic Activity of 5-Hydroxy-7-methoxy-2-phenyl-4-quinolones

  摘要：

  We report the synthesis of 5-hydroxy-7-methoxy-2-phenyl-4-quinolones and their biological activity as antitumor agents. These molecules were initially evaluated for their ability to induce cell cycle arrest in the G2/M phase. Compounds that showed significant G2/M cell cycle arrest were tested for antiproliferative activity using both the MTT assay and the NCI in vitro 60 cell line human tumor screen. The 5-hydroxy-7-methoxy-2-phenyl-4-quinolone (3a) and 2-(3-fluorophenyl)-5-hydroxy-7-methoxy-4-quinolone (3f) were the most active in the cell cycle arrest test whereas 3f was found to be the most active in the MTT assay. In terms of structural requirements, we found that the presence of a 5-hydroxyl group, a 7-methoxy group, and an unsubstituted N1 were essential for the antimitotic activity. In accordance with the literature, a fluoro group at the 3'- or 2'-position and a methoxy or a chloro group at the 3'-position were found to be highly advantageous for both the cell cycle arrest and the antiproliferative activities.

  Copper-Mediated Selective C–H Activation and Cross-Dehydrogenative C–N Coupling of 2′-Aminoacetophenones

  摘要：

  Isatins were obtained by cross-dehydrogenative C-N annulation and dealkylative C-N annulation of 2'-N-aryl/alkylaminoacetophenones and 2'-N,N-dialkylaminoacetophenones respectively in the presence of Cu(OAc)(2)center dot H2O/NaOAc/air. However, on reaction with CuBr, 2'-N-benzylaminoacetophenones underwent selective oxidation of an a-methylene group of amine rather than the 2-acetyl group to provide corresponding benzamides exclusively. Base played an important role in selective oxidation by lowering the temperature and time.

• α-Glucosidase inhibition of 6-hydroxyflavones. Part 3: Synthesis and evaluation of 2,3,4-trihydroxybenzoyl-containing flavonoid analogs and 6-aminoflavones as α-glucosidase inhibitors

  The SAR studies suggested that the C-ring of baicalein (1) was not necessary for the activity, and validated the importance of 2,3,4-trihydroxybenzoyl structure of 1. Thus, a series of 2,3,4-trihydroxybenzoyi-containing flavonoid analogs were investigated for the alpha-glucosidase inhibitory activity. The results indicated that 5,6,7-trihydroxy-2-phenyl-4-quinolone (2) and 5,6,7-trihydroxyflavanone (4) showed the comparable activity to 1, while 3,5,6,7-tetrahydroxyflavone (7), 5,6,7-trihydroxyisoflavone (8), and 6-hydroxygenistein (9) showed moderate alpha-glucosidase inhibitory activity. In addition, it was found that 6-amino-5,7-dihydroxyflavone (16) was a more potent and specific rat intestinal alpha-glucosidase inhibitor than 1, and showed the comparable activity to acarbose. This is the first report on mammalian intestinal alpha-glucosidase inhibitory activity of 6-aminoflavones. Kinetic studies revealed that 16 inhibited both sucrose- and maltose-hydrolyzing activities of rat intestinal alpha-glucosidase uncompetitively/ (C) 2004 Elsevier Ltd. All rights reserved.

  The syntheses of a diverse set of 2-aryl-4-quinolone derivatives were achieved by exposing corresponding acylated 2'aminoacetophenones to microwave irradiation in the presence of NaOH. The microwave accelerated cyclizations were complete within 10-22 min at 120 degrees C giving 57-95% isolated yields. (c) 2006 Elsevier Ltd. All rights reserved.
