Girinimbine is a carbazole alkaloid isolated from the stem bark and root of Murraya koenigii. Here we report that girinimbine is an inhibitor of angiogenic activity both in vitro and in vivo. MTT results showed that girinimbine inhibited proliferation of human umbilical vein endothelial cells, while results from endothelial cell invasion, migration, tube formation, and wound healing assays demonstrated significant time- and dose-dependent inhibition by girinimbine. A proteome profiler array done on girinimbine-treated human umbilical vein endothelial cells showed that girinimbine had mediated regulation of pro-angiogenic and anti-angiogenic proteins. The anti-angiogenic potential of girinimbine was also evidenced in vivo in the zebrafish embryo model wherein girinimbine inhibited neo vessel formation in zebrafish embryos following 24 hours of exposure. Together, these results showed that girinimbine could effectively suppress angiogenesis, suggestive of its therapeutic potential as a novel angiogenesis inhibitor.
柯楠碱是一种从印度楝的茎皮和根中分离出来的咔唑生物碱。在此我们报告,柯楠碱在体外和体内均为血管生成活性的抑制剂。MTT结果显示,柯楠碱抑制人脐静脉内皮细胞的增殖,而内皮细胞侵袭、迁移、管腔形成和伤口愈合试验的结果表明,柯楠碱具有显著的时间和剂量依赖性抑制作用。对经柯楠碱处理的人脐静脉内皮细胞进行的蛋白质组分析阵列显示,柯楠碱介导了促血管生成和抗血管生成蛋白的调节。柯楠碱的抗血管生成潜力在斑马鱼胚胎模型中也得到了证实,在该模型中,暴露24小时后,柯楠碱抑制了斑马鱼胚胎中的新血管形成。总之,这些结果表明,柯楠碱可以有效抑制血管生成,提示其作为一种新型血管生成抑制剂的治疗潜力。
