化合物XW630对成骨细胞的作用

Effects of the New Compound XW630 on Osteoblast *

为探讨新合成化合物ＸＷ６３０对成骨细胞的作用，采用噻唑蓝比色法（ＭＴＴ）法和碱性磷酸酶（ＡＬＰ）测定法观察了ＸＷ６３０对体外培养的成熟大鼠头盖骨成骨细胞的增殖和ＡＬＰ的表达，并用抗酒石酸磷酸酶染色法观察ＸＷ６３０对体外培养的破骨细胞形成的影响。结果显示：ＸＷ６３０有刺激成骨细胞增殖，提高ＡＬＰ活性及抑制甲状旁腺素促进破骨细胞形成的作用，从而表明ＸＷ６３０有可能成为治疗骨质疏松症的有效药物。

This study aimed to observe the influence of the new compound XW630 on the proliferation of osteoblast, ALP action, and the forming of osteoclast. The MTT method and the alkaline phosphatase method were adopted to investigate the influence of XW630 on ALP action and the proliferation of osteoblast cultured from grown rat's skull. The Tartrate resistant acid phosphatase dyeing method was used to observe the influence of XW630 on forming of cultured osteoclast in vitro. The result showed that, when XW630 concentration was 10 -6 10 -8 mol/L, it obviously enhanced the proliferation of osteoblast and improved the activity of ALP, and it evidently provented PTH from stimulating the forming of osteoclast. It is concluded that XW630 is obviously effective for stimulating the proliferation of cultivated osteoblast in vitro and for inhibiting the forming of osteoclast.
