An efficient protocol for the synthesis of β-trifluoroethoxydimethyl selenides was achieved under mild reaction conditions, and 39 compounds were prepared. All compounds were evaluated for their abilities to inhibit RANKL-induced osteoclastogenesis, compound 4aa exhibited the most potent activity. Further investigations revealed that 4aa could inhibit F-actin ring generation, bone resorption, and osteoclast-specific
在温和的反应条件下实现了β-三氟乙氧基二甲基硒化物的有效合成方案,并制备了39种化合物。评估了所有化合物抑制 RANKL 诱导的破骨细胞生成的能力,化合物4aa表现出最有效的活性。进一步的研究表明, 4aa可以在体外抑制 F-肌动蛋白环的生成、骨吸收和破骨细胞特异性基因表达。蛋白质印迹分析表明,化合物4aa消除了 RANKL 诱导的丝裂原激活蛋白激酶和 NF-kB 信号通路。此外, 4aa还对MC3T3-E1前成骨细胞的成骨细胞产生显着影响。体内实验表明,化合物4aa可显着改善卵巢切除 (OVX) 小鼠模型中的骨质流失。此外,表面等离子体共振实验结果表明4aa可能与RANKL结合。总的来说,上述研究结果表明,化合物4aa作为潜在的RANKL抑制剂,通过调节破骨细胞分化的抑制和成骨细胞分化的刺激来避免OVX引发的骨质疏松症。
