BC-LI-0186 是一种有效的选择性亮氨酰-tRNA 合成酶 (LRS; LeuRS) 和 Ras 相关的 GTP 结合蛋白 D (RagD) 相互作用的抑制剂 (IC50=46.11 nM)。 BC-LI-0186 竞争性结合 LRS 的 RagD 相互作用位点 (Kd=42.1 nM)，并影响 LRS-Vps34、LRS-EPRS、RagB-RagD 结合、mTORC1 复合物形成或 12 种激酶的活性。 BC-LI-0186 可以有效抑制癌症相关的 MTOR 突变体的活性和雷帕霉素耐药癌细胞的生
Potent and high affinity leucyl-tRNA synthase (TRS)/Ras-related GTP-binding protein D (RagD) interaction inhibitor (IC50 = 46.1 nM; Kd = 42.1 nM for binding to LRS). Inhibits mTOR complex 1 activity by blocking binding to LRS without affecting catalytic activity. Inhibits leucine-induced translocation of LRS to the lysosome.
