-benzo[e][1,3]oxazine-2,4(3H)-dione derivatives were synthesized and evaluated for their inhibitory effects on osteoclast activities by using TRAP-staining assay. Among the tested compounds, 3d and 3h exhibited more potent osteoclast-inhibitory activities than the lead compound NDMC503 (a ring-fused structure of NDMC101), as reported in our previous study. Both 3d and 3h exhibited two-fold increase
合成了一系列新型的6-(2,4-二氟苯基)-3-苯基-2 H-苯并[ e ] [1,3]恶嗪-2,4(3 H)-二酮衍生物,并对其抑制作用进行了评估TRAP染色法测定破骨细胞的活性 在我们之前的研究中报道,在测试的化合物中,3d和3h表现出比先导化合物NDMC503(NDMC101的环稠合结构)更强的破骨细胞抑制活性。两个3D和3H表现出活性增加两倍相比NDMC503。此外,我们的生物学结果表明3d和3h能抑制RANKL诱导破骨细胞形成有关的标记基因,如NFATc1的,的c-fos,TRAP和组织蛋白酶K。值得注意的是,在窝形成试验中,3d可以显着减弱破骨细胞的骨吸收活性。因此,这项研究可能会提供一类新的铅结构,作为潜在的抗吸收剂,有待进一步开发。
