approaches targeting IL-15. This study is an original approach aimed at discovering small-molecule inhibitors impeding IL-15/IL-15R interaction. A pharmacophore and docking-based virtual screening of compound libraries led to the selection of 240 high-scoring compounds, 36 of which were found to bind IL-15, to inhibit the binding of IL-15 to the IL-2Rβ chain or the proliferation of IL-15-dependent cells or
白介素(IL)-15是一种多效细胞因子,在结构上接近IL-2,并与之共享IL-2β和γ受体(R)亚基。通过促进NK,NK-T和CD8 + T细胞的活化和增殖,IL-15在先天和适应性免疫中起着重要的作用。而且,高水平的IL-15表达与炎性和自身免疫性疾病的关联导致了针对IL-15的各种拮抗方法的发展。这项研究是旨在发现阻碍IL-15 / IL-15R相互作用的小分子抑制剂的原始方法。对化合物库进行药效学和基于对接的虚拟筛选导致选择了240种高得分化合物,其中36种被发现与IL-15结合,从而抑制IL-15与IL-2Rβ链的结合或增殖IL-15依赖性细胞或两者兼有。
