degranulation is IC50=0.0106±0.001 μmol.L-1, histamine release was IC50=0.0192±0.005 μmol.L-1 and β-hexosaminidase release was IC50=0.0455±0.002 μmol.L-1 in vitro. At the same time, in vivo biological activities assay results showed that have a good Histamie induce bronchospasm effect with relatively long duration and good protective effect in vivo, among which the protective effect of compound 5k was 79
在这项研究中,通过用苄基胺对先导化合物进行结构修饰,并利用通过生物等位体形成进行修饰和用烷基进行修饰的原理,获得了一系列新型的乙二胺化合物。在体外实验中,生物学活性表明目标化合物具有抑制肥大细胞脱粒并释放组胺和β-氨基己糖苷酶的特性,例如化合物5c,5g,5k,5l和5o,尤其是化合物5k对肥大细胞脱粒的抑制作用。是IC 50 = 0.0106±0.001μmol.L -1,组胺释放是IC 50= 0.0192±0.005μmol.L -1和β氨基己糖苷酶释放是IC 50 = 0.0455±0.002μmol.L -1 体外。同时,体内生物活性测定结果表明,组胺具有较好的组胺诱导支气管痉挛作用,作用时间相对较长,在体内具有良好的保护作用,其中化合物5k的保护作用为79.74±0.30%,化合物5c,5g,5k,5l和5o可抑制组胺引起的毛细血管通透性增加。
