Osteoporosis is a disorder in which bone mass decreases and is responsible for many degenerative bone diseases. The excessive formation and activity of osteoclasts results in pathological disorders of the bone. Receptor Activator of Nuclear Factor κB Ligand (RANKL) is regarded as a key regulator of osteoclast activity and as a new therapeutic target for treating osteoporosis. Herein, we have synthesized several new small molecules and tested their inhibition activity on RANKL-induced osteoclast formation. The active compounds 2c and 4d showed inhibitory activity against RANKL-induced osteoclast differentiation (IC50 = 1.56 and 2.20 μM, respectively). The most active compound 2c prevented LPS-induced osteoclastogenesis in vivo. These data imply that the compound may be the potential candidate for a new therapeutic drug for treatment of bone resorption-associated diseases.
骨质疏松是一种骨量减少的疾病,导致多种退行性骨病的发生。破骨细胞的过度形成和活跃性会导致骨骼的病理性紊乱。核因子κB配体受体激活因子(RANKL)被认为是破骨细胞活性的关键调节因子,也是治疗骨质疏松的新疗法靶点。在此,我们合成了几种新型小分子,并测试了它们对RANKL诱导的破骨细胞形成的抑制活性。活性化合物2c和4d对RANKL诱导的破骨细胞分化表现出抑制活性(IC50分别为1.56和2.20 μM)。最活跃的化合物2c在体内防止了LPS诱导的破骨细胞生成。这些数据表明,该化合物可能是治疗与骨吸收相关疾病的新型候选药物。
