therapeutic agents for the treatment of low bone mass. To enrich our understanding of SAR and based on our previously concluded structure–effect relationship, 23 derivatives were prepared in this work. The synthesis, up-regulating activities on BMP-2 expression, and bone loss prevention efficacies of these compounds in rats with glucocorticoid-induced osteoporosis are presented. The bone histology of
BMP途径是设计用于治疗低骨量的治疗剂的有希望的新目标。为了丰富我们对SAR的理解,并基于我们先前得出的结构效应关系,在这项工作中准备了23种衍生物。提出了这些化合物在糖皮质激素诱导的骨质疏松症大鼠中的合成,上调其BMP-2表达的活性以及预防骨丢失的功效。通过光学显微镜评估所测试的大鼠的骨组织学表明,化合物1,21,35,和与模型组相比,38显著增加了小梁,以及与治疗的组的小梁8A与雷洛昔芬和阿法骨化醇相似。该化合物显示出发展为同化剂的潜力。
