substituted-flavone derivatives have been synthesized from the lead compounds and were screened against 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging and α-glucosidase inhibitory properties. The resulting activity profiles of these flavone derivatives were compared for degree of similarity to the profile of 1–3. Most of the synthesized derivatives displayed potent activities when compared
出于药理作用的天然产物研究已经产生了具有有趣的生物医学特性的多种结构独特的先导化合物,但是这些分子的天然作用通常仍然是未知的。在本研究中,已从先导化合物合成了一系列苄基取代的黄酮衍生物,并针对1,1-二苯基-2-吡啶并肼基(DPPH)自由基清除和α-葡萄糖苷酶抑制性质进行了筛选。比较了这些黄酮衍生物的活性分布与1 – 3的相似程度。与母体化合物相比,大多数合成衍生物都显示出强大的活性。仅在苯环上含有4-羟基取代基和3-甲氧基的化合物中才能观察到DPPH自由基清除活性的最大潜力。尽管苯环上的2和4羟基取代似乎对肠道α-葡萄糖苷酶抑制活性至关重要。
