4-羟基查耳酮 用途与合成方法
| Target | Value |
|
NF-κB
() |
4'-Hydroxychalcone (20-40 μM ; 2 hours) inhibits TNFα-induced (20 ng/mL; 6 hours) NF-kB pathway activation in a dose-dependent manner.
4'-Hydroxychalcone (0.1-25 μM ; 8 hours) inhibits proteasome activity in a dose-dependent manner but has no effect on IKK activity.
4'-Hydroxychalcone inhibits TNFα-dependent degradation of IkBα and subsequently prevents p50/p65 nuclear translocation leading to 4'-Hydroxychalcone-inhibited expression of NF-kB target genes.
4'-Hydroxychalcone affects cancer cell viability but has no significant effect on non-transformed cell viability.
Cell Viability Assay
| Cell Line: | K562 cells, Jurkat cells, U937 cells, PBMCs |
| Concentration: | 5 μM, 10 μM, 20 μM, 24 μM, 28 μM, 32 μM, 40 μM, 60 μM |
| Incubation Time: | 24 hours |
| Result: | Affected cancer cell viability but has no significant effect on non-transformed cell viability. |
Western Blot Analysis
| Cell Line: | Jurkat cells |
| Concentration: | 60 μM (followed by TNFα 20 ng/mL ) |
| Incubation Time: | 2 hours |
| Result: | Inhibited TNFα -dependent degradation of IkBα and prevents p50/p65 nuclear translocation. |
4'-Hydroxychalcone has hepatoprotective activity against Acetaminophen induced hepatotoxicity in mice.
| Animal Model: | Male albino mice(5-30 g) |
| Dosage: | 25 mg/kg, 50 mg/kg, 100 mg/kg |
| Administration: | Oral administration, 12h intervals, 4 doses |
| Result: | Significantly reduced the mortality rate induced by Acetaminophen (1 g/kg). |

向反应瓶中加入对羟基苯乙酮（1 mmol）和苯甲醛（表2中2 mmol；表3中1 mmol），以及Mo10V2/SiO2催化剂（负载量为40 wt%，其中Mo10V2占19-32.5 wt%，ICP分析结果显示Mo含量略低于制备时的化学计量预期，具体为0.06 g，即0.010 mol/mol Mo10V2相对于底物酮）。将混合物在50℃下搅拌反应适当时间。反应进程通过薄层色谱（TLC）监控，使用正己烷/乙酸乙酯（10:4，v/v）作为洗脱剂。反应完成后，向反应混合物中加入乙醚（2×10 mL），过滤分离催化剂。催化剂经洗涤干燥后可重复使用。滤液经减压浓缩除去溶剂后，通过柱色谱分离得到纯的1-(4-羟基苯基)-3-苯基丙-2-烯-1-酮。
