  新型色酮类似物对白介素5抑制活性的合成与评价

  摘要：

  合成了一系列新的色酮类似物，并评估了其对白介素5的抑制活性。其中化合物5-环己基甲氧基-3-（4-羟基苄基）-4 H- 铬-4--4-酮（6a，在30μM时抑制率为98％，IC 50 <3.0μM）和5-环己基甲氧基-3-（羟甲基）- 4 H -chromen-4-one（8a，30μM时抑制84％，IC 50 = 7.6μM）表现出最强的活性。具有抑制IL-5抑制活性的色酮类似物的结构要求可以概括为：（i）疏水基团（在环A的第5位的环己基甲氧基）的重要性，（ii）具有较小氢键基团的环B的要求具有给电子性，例如在第4位的酚羟基和（iii）1-4n铬烯环的平面性。

  Identification of novel chromenone derivatives as interleukin-5 inhibitors

  摘要：

  A series of (E)-5-alkoxy-3-(3-phenyl-3-oxoprop-1-enyl)-4H-chromen-4-ones (4) and (E)-5-alkoxy-3-(3-hydroxy-3-phenylprop-1-enyl)-4H-chromen-4-ones (5) were synthesized and evaluated for their IL-5 inhibitory activity. Propenone analogs 4 possess some of the structurally important characteristics of isoflavone 2 and chalcone 3 previously known as potent IL-5 inhibitor. However, the inhibitory activity of 4 was weak and therefore this structural hybridization appears to be ineffective for the design of IL-5 inhibitor. Meanwhile the potent activity profile of compounds 5 was discovered. This enhanced activity of 5 compared to 4 could be due to the effective location of hydroxyl group of allylic alcohol moiety of 5 in the 3D structure. The electron withdrawing substituents at position 4 of phenyl ring of 5 enhances the activity possibly due to an increase in the strength of hydrogen bonding property of hydroxyl group of allylic alcohol moiety.

  A novel family of 3-((4-oxo-4H-chromen-3-yl)methyl)-4H-chromen-4-one (bis-chromone) derivatives were designed, synthesized and studied for their anti-cancer activity using the XTT assay for the growth inhibition against various human cancer cells. Among them, 3-((5-(cyclohexylmethoxy)-4-oxo-4H-chromen- 3-yl)methyl)-7-methoxy-4H-chromen-4-one and 3-((5-(cyclohexylmethoxy)-4-oxo-4H-chromen- 3-yl)methyl)-7-hydroxy-4H-chromen-4-one showed micromolar level of in vitro anti-proliferative activity against human cancer cell lines. The SAR studies indicated bis-chromone as a basic scaffold to design anticancer agents. The 5-cyclohexylmethoxy on the first chromenone ring and electron donating group such as CH3, OCH3 or hydrogen bonding group (OH) on the other chromenone ring of bis-chromone increased the activity. However, saturation of one of chromenone to chromanone in bis-chromones decreased the activity. (C) 2014 Elsevier Ltd. All rights reserved.
