反式-查耳酮 MSDS1,3-Diphenyl-2-propen-1-one
在氮气下，将[Ni（dmpymt）2] 6（5 mol％Ni），KOH（1.0 mmol），苯甲醇（1.5 mmol）和1-苯基乙醇（1.0 mmol）与甲苯（2.5 mL）/ t-BuOH（0.5 mL）加入50毫升Schlenk试管中，将试管置于70°C油浴中，在缓慢，稳定的氮气流中搅拌混合物36小时，将混合物冷却至室温，加水（10毫升）。 用CH2Cl2（3×10 mL）萃取水溶液，用无水Na2SO4干燥合并的萃取液，除去溶剂，在短时间快速柱色谱上纯化粗产物得到反式-查耳酮。
trans-Chalcone competitively inhibits porcine pancreatic α-amylase with a Ki of 48 μM. trans-Chalcone (30.23-98.03 μM; 24 hours) induces cell cycle arrest and apoptosis in MCF-7 cells. trans-Chalcone (30.23-98.03 μM; 24 hours) reduces the expression of the apoptosis-related protein Bcl-2 and induces the expression of the CIDEA gene. trans-Chalcone (58.25 μM; 6, 24 hours) has greater inhibition of Bcl-2, induction of APAF1 and BAX, and strong induction of CIDEA in 24 hours. trans-Chalcone (24 hours) inhibits MCF-7 cell viability (IC 20 =30.23 μM; IC 50 =58.25 μM; IC 80 =98.03 μM). trans-Chalcone (48 h) has IC 50 s of 41.53 μM and 48.41 μM for MCF-7 and 3T3 cell lines, respectively. trans-Chalcone exhibits a pronounced cytotoxicity activity.
