摘要: 目的 ·基于 THP-1-HIF-1α-HER-Luciferase高通量筛选模型,对化合物的抗动脉粥样硬化( atherosclerosis,AS)活性进行筛选,并对有效化合物的抗 AS功能进行验证。方法 ·利用不同浓度( 1、10和 100 μg/mL)的 200种化合物预处理 THP-1-HIF-1α-HERLuciferase细胞 2 h,再低氧培养 24 h,收集细胞并检测荧光素酶活性,通过荧光素酶活性的变化评价化合物抗 AS活性。利用有效化合物预处理单核巨噬细胞 THP-1和 U937,再经氧化低密度脂蛋白( oxidized low density lipoprotein,OX-LDL)诱导 24 h,通过油红染色观察泡沫细胞形成,实时荧光定量 PCR(real-time quantitative PCR,qPCR)检测缺氧诱导因子 1α(hypoxia-inducible factor 1α, HIF-1α)的 mRNA含量,蛋白印迹法( Western blotting)检测 HIF-1α的蛋白表达,并分析有效化合物的抗 AS活性。结果 · 200种化合物中,有 11种化合物能够有效抑制由低氧引起的 THP-1-HIF-1α-HER-Luciferase细胞内荧光素酶活性升高(均 P<0.05);其中,化合物 C14抑制作用最为显著。THP-1和 U937细胞由 OX-LDL诱导 24 h可出现泡沫化,化合物 C14对其预处理 2 h则能够明显抑制由 OX-LDL引起的单核细胞泡沫化。qPCR和 Western blotting检测显示,OX-LDL诱导 THP-1和 U937细胞 24 h可明显增强胞内 HIF-1α mRNA含量及其蛋白的表达( P<0.05),而 C14预处理则能梯度依赖地抑制由 OX-LDL诱导的胞内 HIF-1α mRNA含量及其蛋白表达的增强( P<0.05)。结论 ·抗 AS化合物的高通量筛选模型 THP-1-HIF-1α-HER-Luciferase具有较高的可靠性,化合物 C14具有良好的抗 AS活性特征。

Abstract: Objective · To screen the anti-atherosclerosis (AS) activity of the compoundsusing THP-1-HIF-1α-HER-Luciferase high-throughput model, and to verify the anti-AS function of the effective compounds. Methods · THP-1-HIF-1α-HER-Luciferase cells were pretreated with different concentrations of compounds (1, 10, and 100 μg/mL) for 2 h, then cultured under hypoxia for 24 h. Luciferase activity of cells was detected and compounds with anti-AS activity were screenedluciferase activity evaluation. THP-1 and U937 cells were pretreated with effective compounds, and then induced for 24 hoxidized low density lipoprotein (OX-LDL). The formation of foam cells was observedoil red staining. The mRNA level of hypoxia-inducible factor 1α (HIF-1α) was detectedreal-time quantitative PCR (qPCR). HIF-1α protein was detectedWestern blotting. Anti-AS activity of effective compounds were evaluated. Results · Among the 200 compounds, 11 compounds could significantly inhibit the increase of luciferase activity in THP-1-HIF-1α-HER-Luciferase cells inducedhypoxia (all P<0.05), and compound numbered 14 (C14) had the most significant inhibitory effect. THP-1 and U937 cells formed foam cells induced for 24 hOX-LDL. However, cells were pretreated with C14 for 2 h, which could significantly inhibit the formation of foam cells inducedOX-LDL. Cells were induced for 24 hOX-LDL, which could significantly increase the of HIF-1α mRNA and protein (all P<0.05), while cells pretreated with C14 could significantly inhibit the increase of HIF-1α mRNA and protein in a gradient-dependent manner (all P<0.05). Conclusion · THP-1-HIF-1α-HER-Luciferase high-throughput model can be reliability used in screening of compounds with anti-AS activity. C14 has the good anti-AS activity characteristics.
