been made to inhibit RANKL. For example, marketed monoclonal antibody drug Denosumab could inhibit the maturation of osteoclasts by binding to RANKL. This study is an original approach aimed at discovering small-molecule inhibitors impeding RANKL/RANK protein interaction. We identified compound 34 as a potent and selective RANKL/RANK inhibitor by performing structure-based virtual screening and hit optimization
靶向RANKL / RANK提供了开发新颖的治疗方法来治疗骨代谢疾病的可能性。为了抑制RANKL已经做出了多种努力。例如,市售的单克隆抗体药物Denosumab可以通过与RANKL结合来抑制破骨细胞的成熟。这项研究是旨在发现阻碍RANKL / RANK蛋白相互作用的小分子抑制剂的原始方法。通过执行基于结构的虚拟筛选和命中优化,我们确定了化合物34为有效的选择性RANKL / RANK抑制剂。34对RANKL / RANK相互作用的破坏有效抑制了RANKL诱导的破骨细胞生成和骨吸收。破骨细胞标记基因的表达也受到34的抑制。此外,34显着阻断了NFATc1 / c-fos途径。因此,
