efficient approach has been developed for the synthesis of naturally occurring prenylated chalcones viz. kanzonol C ( 1 ), stipulin ( 2 ), crotaorixin ( 3 ), medicagenin ( 4 ), licoagrochalcone A ( 5 ) and abyssinone D ( 6 ) along with the pyranochalcones paratocarpin C ( 7 ), anthyllisone ( 8 ) and 3- O -methylabyssinone A ( 9 ). The key step of the synthesis is a Claisen–Schmidt condensation. Subsequently
摘要已开发出一种有效的方法来合成天然存在的烯丙基查耳酮。坎佐诺尔C(1),链球菌素(2),Crotaorixin(3),药物元素素(4),利加格查尔酮A(5)和Abyssinone D(6)以及吡喃丙酮副棕榈素C(7),蒽醌(8)和3- O。 -甲基杜鹃花A(9)。合成的关键步骤是克莱森-施密特缩合反应。随后,在脂多糖(LPS)诱导的RAW-264.7巨噬细胞中研究了它们的抗炎作用。在合成的查耳酮中,化合物5(IC 50 = 10.41μmol/ L),化合物6(IC 50 = 9.65μmol/ L)和化合物8(IC 50 = 15.34μmol/ L)表现出显着的活性,没有细胞毒性。化合物9(IC 50 = 4.5μmol/ L)表现出最大(83.6%)一氧化氮(NO)抑制作用,但显示出轻微的细胞毒性。
