discover modified salicylanilides and 3-phenyl-2H-benzo[e][1,3]oxazine-2,4(3H)-dione derivatives as potential antiosteoclastogenic agents. Their inhibitory effects on RANKL-induced osteoclastogenesis from RAW264.7 cells were evaluated by TRAP stain assay. The most potent compounds, 1d and 5d, suppressed RANKL-induced osteoclast formation and TRAP activity dose-dependently. The cytotoxicity assay on RAW264
抑制破骨细胞形成是防止炎症性骨吸收和治疗骨疾病的潜在策略。在目前的工作,目的是为了发现改性水杨和3-苯基-2- ħ苯并[ ë ] [1,3]恶嗪-2,4-(3 ħ) -二酮衍生物作为潜在antiosteoclastogenic剂。通过TRAP染色法评估了它们对来自RAW264.7细胞的RANKL诱导的破骨细胞形成的抑制作用。最有效的化合物1d和5d抑制RANKL诱导的破骨细胞形成和TRAP活性呈剂量依赖性。对RAW264.7细胞的细胞毒性试验表明,这些化合物对破骨细胞骨吸收的抑制作用并非源于其细胞毒性。此外,这两种化合物均下调了RANKL诱导的细胞核中的NF-κB和NFATc1,抑制了破骨细胞生成过程中与破骨细胞生成相关的标记基因的表达,并阻止了破骨细胞的骨吸收,但并未损害MC3T3-E1中成骨细胞的分化。因此,这些改性的水杨酰苯胺和3-苯基-2 H-苯并[ e ] [1,3]恶嗪-2,4(3
