BC-LI-0186 is a potent and selective inhibitor of Leucyl-tRNA synthetase (LeuRS) and Ras-related GTP-binding protein D (RagD) interaction (IC50=46.11 nM). It competitively binds to the RagD interacting site of LRS (Kd=42.1 nM). At the same time, it has effects on LRS-Vps34, LRS-EPRS, RagB-RagD association, mTORC1 complex formation, or the...
