of functionalized aurones has been accomplished via the reaction of benzofuran-3(2H)-one with a range of benzaldehydes in the presence of a mild base EDDA under ultrasound. A number of aurones were synthesized (within 5–30 min) and the molecular structure of a representative compound determined by single crystal X-ray diffraction study confirmed Z-geometry of the C–C double bond present within the
在超声波下,在温和的碱EDDA存在下,苯并呋喃3(2 H)-one与一系列苯甲醛的反应已实现了功能化金氧烷的改进合成。合成了许多金氧化合物(在5-30分钟内),通过单晶X射线衍射研究确定的代表性化合物的分子结构证实了分子中存在的C-C双键的Z-几何形状。某些合成的化合物在体外显示出对两种癌细胞系具有SIRT1抑制作用以及抗增殖特性。化合物3a [(Z)-2-(5-溴-2-羟基亚苄基)苯并呋喃-3(2 H)-一]被确定为SIRT1的有效抑制剂(IC 50 = 1μM),这显示p53乙酰化的剂量依赖性增加,导致细胞凋亡的诱导。
