of dalbergin have been described via the introduction of cyclic amine, ester and amide groups. Among the twenty-three prepared novel analogues of dalbergin, compound 4d (EC50 2.3μM) showed significantly increased proliferation as assessed by alkaline phosphatase activity and mineralization in calvarial osteoblast cells in vitro. Compound 4d, at a dose of 1.0mg/kg body weight exhibited the significant
通过引入环胺基,酯基和酰胺基,已经描述了黄柏苷羟基的化学修饰。在二十三个制备的达伯格素新类似物中,化合物4d(EC502.3μM)显示出通过碱性磷酸酶活性和体外颅骨成骨细胞中的矿化作用而显着增加的增殖。剂量为1.0mg / kg体重的化合物4d显示出显着的骨保护作用。在相同剂量的体内试验中,与对照组相比,其成骨基因表达RunX2(〜4倍),ALP(〜5倍),OCN(〜4倍)和COL1(〜4倍)显着增加。
