A novel series of chromone analogs were synthesized and evaluated for their inhibitory activity against interleukin-5. Among them compounds 5-Cyclohexylmethoxy-3-(4-hydroxybenzyl)-4H-chromen-4-one (6a, 98% inhibition at 30 μM, IC50 < 3.0 μM) and 5-Cyclohyxylmethoxy-3-(hydroxymethyl)-4H-chromen-4-one (8a, 84% inhibition at 30 μM, IC50 = 7.6 μM) showed most potent activity. The structural requirement
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。
