我们之前报道了从牡丹皮中分离的丹皮酚的抗血管生成活性。在本研究中,我们研究了丹皮酚肟(PO,丹皮酚衍生物)对人脐静脉内皮细胞(HUVEC)中碱性成纤维细胞生长因子(bFGF)介导的血管生成(包括肿瘤血管生成)的负面影响以及HT-1080纤维肉瘤细胞系中的促生存活性。我们发现 PO (IC50 = 17.3 µg/ml) 显着抑制 bFGF 诱导的细胞增殖,这是通过较高浓度的丹皮酚实现的(IC50 超过 200 µg)。 PO 治疗以剂量依赖性方式阻断 bFGF 刺激的迁移和体外毛细血管分化(管形成)。此外,PO 能够破坏体内新血管形成。有趣的是,PO (25 µg/ml) 降低了 HT-1080 纤维肉瘤细胞的细胞活力,但不降低 HUVEC 的细胞活力。 12.5 µg/ml PO 处理降低了 HT-1080 细胞中磷酸化 AKT 和 VEGF 表达(细胞内和细胞外)的水平。免疫荧光成像分析一致表明,PO 处理减弱了 HT-1080 细胞中的 AKT 磷酸化。综上所述,这些结果表明 PO 抑制 HUVEC 中 bFGF 诱导的血管生成,并降低 HT-1080 细胞中 PI3K、磷酸化 AKT 和 VEGF 的水平。
We previously reported the anti-angiogenic activity of paeonol isolated from Moutan Cortex. In the present study, we investigated the negative effect of paeonol oxime (PO, a paeonol derivative) on basic fibroblast growth factor (bFGF)-mediated angiogenesis in human umbilical vein endothelial cells (HUVECs) (including tumor angiogenesis) and pro-survival activity in HT-1080 fibrosarcoma cell line. We showed that PO (IC50  = 17.3 µg/ml) significantly inhibited bFGF-induced cell proliferation, which was achieved with higher concentrations of paeonol (IC50 over 200 µg). The treatment with PO blocked bFGF-stimulated migration and in vitro capillary differentiation (tube formation) in a dose-dependent manner. Furthermore, PO was able to disrupt neovascularization in vivo. Interestingly, PO (25 µg/ml) decreased the cell viability of HT-1080 fibrosarcoma cells but not that of HUVECs. The treatment with PO at 12.5 µg/ml reduced the levels of phosphorylated AKT and VEGF expression (intracellular and extracelluar) in HT-1080 cells. Consistently, immunefluorescence imaging analysis revealed that PO treatment attenuated AKT phosphorylation in HT-1080 cells. Taken together, these results suggest that PO inhibits bFGF-induced angiogenesis in HUVECs and decreased the levels of PI3K, phospho-AKT and VEGF in HT-1080 cells.
