金合欢素性质、用途与生产工艺
-
植物来源
金合欢 （Acacia farnesiana (Linn.) Willd.） (Mimosa) 豆科。灌木，高2-4米；枝具刺，刺长可达1-2厘米。二回羽状复叶，羽片4-8对，每羽片具小叶10-20对，小叶片线状长椭圆形。头状花序腋生，直径1.5厘米，常多个簇生。荚果圆柱形，长3-7厘米，直径8-15毫米。种子多数，黑色。 花极香，供提取香精。 刺灌术或小乔木，二回羽状复叶，头状花序簇生于叶腋，盛开时，好像金色的绒球一般。
- 生物活性 Acacetin (5,7-Dihydroxy-4'-methoxyflavone) 是一种口服有效的类黄酮，来自 Tephroseris kirilowii (Turcz.) Holub。Acacetin 停在 PI3Kγ 的 ATP 结合口袋中。Acacetin 导致癌细胞周期停滞，并诱导细胞凋亡和自噬。Acacetin 具有有效的抗癌和抗炎活性，有用于疼痛相关疾病研究的潜力。

体外研究
Acacetin (5,7-Dihydroxy-4'-methoxyflavone; 10-200 μM; 24 hours) decreases cell viabilities in a dose-dependent manner. Acacetin has little effect on human normal glial cell line HEB and non-tumorigenic epithelial cell line MCF-10A.
Acacetin (50-150 μM; 24 hours) causes G2/M cell cycle arrest and induces apoptosis and autophagy.
Acacetin (50-150 μM; 24 hours) leads to decreases in levels of PI3Kγ-p110, p-AKT, p-mTOR, p-p70S6K, and p-ULK in a dose-dependent manner.
Cell Viability Assay
Cell Line: Breast cancer MCF-7 cells, hepatocellular carcinoma SMMC-7721 cells, lung adenocarcinoma A549 cells, esophageal carcinoma Eca109 cells Concentration: 10, 20, 40, 60, 80, 100, 150, 200 μM Incubation Time: 24 hours Result: Decreased cancer cell viabilities in a dose-dependent manner.
Had IC 50 values of 82.75 μM, 103.9 μM, 157.4 μM, 54.7 μM in MDA-MB-231, MCF-7, A549, Eca109 cells, respectively.Cell Cycle Analysis
Cell Line: MDA-MB-231 cells Concentration: 50, 100, 150 μM Incubation Time: 24 hours Result: Resulted in increase in percentage of cells at G2/M phase and decrease in percentage of cells at G1 and S phase in a dose-dependent manner. Apoptosis Analysis
Cell Line: MDA-MB-231 cells Concentration: 50, 100, 150 μM Incubation Time: 24 hours Result: Induced apoptosis. Cell Autophagy Assay
Cell Line: MDA-MB-231 cells Concentration: 50, 100, 150 μM Incubation Time: 24 hours Result: Induced autophagy.
Resulted in marked increases in EGFP-LC3 puncta formation and a dose-dependent accumulation of LC3-II.Western Blot Analysis
Cell Line: MDA-MB-231 cells Concentration: 50, 100, 150 μM Incubation Time: 24 hours Result: Resulted in decrease in levels of Bcl-2 and Bcl-xL and increase in levels of p53.
Led to decreases in levels of PI3Kγ-p110, p-AKT, p-mTOR, p-p70S6K, and p-ULK in a dose-dependent manner.
Had little or no effect on expression of PI3Kα, PI3Kβ, PI3Kδ, p-ERK, p-p38, and p-JNK. -
