series of twenty 1-(4/6-substitutedbenzo[]thiazol-2-yl)-3-(phenyl/substitutedphenyl)indeno[1,2-]pyrazol-4(1)-ones was achieved by the reaction of 2-(benzoyl/substitutedbenzoyl)-(1)-indene-1,3(2)-dione and 2-hydrazinyl-4/6-substitutedbenzo[]thiazole in presence of freshly dried ethanol and glacial acetic acid under reflux conditions in good yields. The newly synthesized derivatives were well characterized
一系列二十种 1-(4/6-取代苯并[]噻唑-2-基)-3-(苯基/取代苯基)茚并[1,2-]吡唑-4(1)-酮的环保简便合成是通过2-(苯甲酰基/取代苯甲酰基)-(1)-茚-1,3(2)-二酮和2-肼基-4/6-取代苯并[]噻唑在新鲜干燥的乙醇和冰醋酸存在下反应实现的酸在回流条件下收率良好。使用不同的物理和光谱技术(FTIR、1H NMR、13C NMR 和 HRMS)对新合成的衍生物进行了很好的表征。所有化合物均被评估其β-淀粉酶和葡萄糖扩散抑制活性。其中,化合物 和 表现出更好的 β-淀粉酶抑制活性,与标准药物阿卡波糖(IC 值为 103.60±2.15 µg/mL)相比,IC 值分别为 92.99±1.94 µg/mL 和 95.41±3.92 µg/mL。衍生物和标准参考阿卡波糖 (2.76±0.55 µg/mL) 表现出良好的葡萄糖扩散抑制作用,其值分别为 2.25±1.16 µg/mL
