補骨脂乙素性質、用途與生產工藝
Isobavachalcone (Corylifolinin) 來源于補骨脂,是一種 Akt 信號通路的有效抑制劑,可誘導人類癌細胞凋亡 (以 IC50 值為 7.92 μM 抑制 OVCAR-8 癌細胞生長),具有抗癌和抗增殖活性。Isobavachalcone 還能誘導 OVCAR-8 細胞中活性氧的產生。
IC50: 7.92 μM (OVCAR-8 cell)
Isobavachalcone (6.0-48.0 μM; 72 hours; OVCAR-8, PC3, A549, MCF-7, L-02 and HUVEC cells) treatment inhibits the proliferation of human cancer cells. Isobavachalcone inhibits PC3, A549, MCF-7, L-02 and HUVEC cells growth with IC50 values of 15.06 μM, 32.2 μM, 28.29 μM, 31.61 μM and 31.3 μM, respectively.
Isobavachalcone (0-18 μM; 6 hours; OVCAR-8 and PC3 cells) treatment results in a concentration-and time-dependent down-regulation of the Ser-473 phosphorylation of Akt and GSK3b phosphorylation.
Isobavachalcone (0-18 μM; 72 hours; OVCAR-8 and PC3 cells) treatment causes apoptosis via caspase- and ROS-involved mitochondrial pathway.

生產方法
以化合物(CAS: 1449202-18-9)為原料合成1-(2,4-二羥基-3-(3-甲基-2-丁烯-1-基)苯基)-3-(4-羥基苯基)丙-2-烯-1-酮的一般步驟如下:
通用方法:
1. 在0℃下,將化合物13(100 mg,0.22 mmol)溶于甲醇(2 mL)中,緩慢加入1N鹽酸水溶液(1 mL)。
2. 將反應混合物加熱至50℃,維持該溫度反應6小時。
3. 反應完成后,將混合物冷卻至室溫,隨后在真空條件下除去甲醇。
4. 加入乙酸乙酯(10 mL)進行萃取,分離有機層和水層。
5. 水層用乙酸乙酯(2×10 mL)進一步萃取,合并所有有機層。
6. 有機層用無水硫酸鎂干燥,過濾后真空濃縮,得到粗產物。
7. 粗產物通過硅膠快速色譜法純化,洗脫劑為正己烷/乙酸乙酯(15:1),得到目標產物巴伐利亞酮(53 mg,收率75%),為黃色固體。
注:該方法同樣適用于以化合物22(100 mg,0.22 mmol)為底物制備化合物1,反應條件與上述相同,最終得到化合物1(53 mg,收率75%),為黃色固體。
