摘 要:目的利用斑马鱼模型考察中药单体靛玉红(Ind)及其衍生物的抑制血管生成活性及其量效关系,并为斑马鱼模型在新药构效关系研究中的应用提供实验依据。方法选用TG(VEGFR2:GFP)系血管荧光转基因斑马鱼作为筛选模型,分别用Ind及其衍生物靛玉红-3’-单肟(IMO)、6-溴-靛玉红-3’-单肟(BIO)处理斑马鱼胚胎,以节间血管数作为指标,考察药物对斑马鱼胚胎抑制血管生成的影响。结果在相同的剂量下,Ind、IMO与BIO抑制斑马鱼节间血管(ISV)生成的作用依次增强,三者都显示明显的量效关系。Ind、IMO与BIO的半数有效剂量(EC50),分别为89.10,5.188和2.686μmol.L 1。结论在靛玉红母体结构改造中,随着C-3’位肟化以及C-6位溴原子的引入,溶解性明显改善,其抑制血管生成活性也逐渐增强。OBJECTIVE To investigate the antiangiogenesis derivatives using zebrafish model which will contribute to the effect and dose-effect relationship of indirubin(Ind) and its structure-activity relationship of new drugs. METHODS Intersegmental vessel number(ISV) in transgenic line VEGFR2: GFP zebrafish was used to evaluate angiogenesis inhibition effect after indirubin(Ind), its derivatives indirubin-Y-monoxime(IMO) and (2'Z,YE)-6-Bromoindirubin-3'-oxime(BIO) treated zebrafish embryos. RESULTS At the same dose, BIO showed the strongest effect of antiangiogenesis, followed by IMO and Ind. The inhibition effects of three compounds were obviously dose-dependent. Furthermore, the median effective -1 concentration(EC50) of Ind, IMO and BIO were 89.10, 5.188 and 2.686 μmol-L , respectively. CONCLUSION After addition of oximido at the C-3' and bromine at the C-6 in the structure of Ind, the solubility of IMO and BIO obviously increased and their antiangiogenesis effect enhanced simultaneously.
