A series of 3,4-diarylbenzopyran based amide derivatives was synthesized and evaluated for osteogenic activity in in vitro and in vivo models of osteoporosis. Compounds 17a, 21b–c and 22a–b showed significant osteogenic activity in osteoblast differentiation assay. Among the synthesized compounds, 22b was identified as lead molecule which showed significant osteogenic activity at 1 pM concentration
合成了一系列基于3,4-二芳基苯并吡喃的酰胺衍生物,并在骨质疏松症的体外和体内模型中评估了其成骨活性。化合物17a,21b–c和22a–b在成骨细胞分化试验中显示出显着的成骨活性。在合成的化合物中,鉴定出的铅分子22b在成骨细胞分化试验中浓度为1 pM时和在雌激素缺乏的balb / c小鼠模型中剂量为1 mg kg -1体重时显示出显着的成骨活性。体外骨矿化和成骨标记基因的表达vizBMP-2,RUNX-2,OCN和1型胶原蛋白进一步证实了22b的成骨潜力。小鼠颅骨成骨细胞(MCOs)中雌激素受体α和β(ER-α和ER-β)的基因表达研究表明,可能22b通过优先激活雌激素受体β发挥成骨功效。22b的体内药代动力学,雌激素性和急性毒性研究表明,它具有良好的生物利用度,分别在1 mg kg -1的剂量和高达1000 mg kg -1体重的剂量时没有子宫雌激素性。
