  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

  摘要：

  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 one-step cyclocondensation of substituted isoflavones with cyanothioacetamide in the presence of sodium hydroxide gave an array of 3-cyano-5,6-diaryl pyridine-2(1H)-thiones in good yields. The procedure involves base-mediated ring opening of the isoflavones and subsequent Knoevenagel condensation between the 1,3-dicarbonyl intermediate generated from the isoflavones and cyanothioacetamide, followed

  The 2,3-diarylpyrimido[1,2-a]benzimidazole derivatives were prepared by one-step cyclocondensation of 2-aminobenzimidazole with isoflavone in methanol. Single-crystal diffraction analysis was performed for 2-(2-hydroxyl-4-isopropoxy-phenyl)-3-phenylpyrimido[1,2-a]benzimidazole. The fluorescence properties of the fused 2, 3-diarylpyrimido[1, 2-a]benzimidazole were evaluated.
