Pyrano[3,2-c]pyranone is an important structural motif present in many natural products exhibiting diverse biological activities. Two series of carbohydrate fused pyrano[3,2-c]pyranone derivatives (n = 20) were efficiently synthesized starting from 2-C-formyl galactal and 2-C-formyl glucal, reacting with various 4-hydroxycoumarins in a very short reaction time (10 min) under microwave assisted conditions
吡喃并[3,2- c ]吡喃酮是存在于表现出多种生物活性的许多天然产物中的重要结构基序。从2- C-甲酰基半乳糖和2- C-甲酰基葡糖开始,高效合成了两个系列的碳水化合物稠合的吡喃并[3,2- c ]吡喃酮衍生物(n = 20),可在很短的时间内与各种4-羟基香豆素反应微波辅助条件下的时间(10分钟)。这些合成的吡喃并[3,2- c ]吡喃酮的抗癌活性通过针对MCF-7(乳腺癌),MDA-MB-231(乳腺癌)和HepG2(肝)癌细胞系的细胞分析进行了详细测定。新合成的吡喃并[3,2- c筛选]吡喃酮对MCF-7,MDA-MB-231和HepG2细胞系的细胞活力和抗增殖活性。化合物12,13和14有选择地显示出高的生长抑制能力对MCF-7细胞用半最大抑制浓度(IC 50)为19.9,分别14.5和10.9μM值。化合物12,13,14,15和19分别抑制MDA-MB-231细胞(乳腺)的生
