Biochem/physiol Actions

BC-LI-0186 is a selective blocker of Leucyl-tRNA synthetase (LRS; LeuRS) and Ras-related GTP-binding protein D (RagD) interaction (IC50 = 46.11 nM) by competing against RagD for LRS VC domain binding (KD = 42.1 nM) without affecting LRS-Vps34, LRS-EPRS, RagB-RagD association, mTORC1 complex formation or the activities of 12 kinases. BC-LI-0186 inhibits Leu-dependent LRS lysosomal membrane localization (10 μM), RagD GTPase and mTORC1 activation (IC50 = 81.4 nM against Leu-induced S6K phosphorylation), but not ARF1 activation, AKT S473 phosphorylation, Glu- or Arg-dependent S6K phosphorylation, nor the cytosolic and mitochondrial LRS catalytic activities. BC-LI-0186 effectively suppresses the growth of rapamycin-resistant MCT116 MM cancer cells with mTOR-S2035I mutation both in cultures (GI50 = 42.03) and in mice in vivo (by 40% in 2 wks; 20 mg/kg/day i.p.).

Leucyl-tRNA synthetase (LRS) plays major roles in providing leucine-tRNA and activating mechanistic target of rapamycin complex 1 (mTORC1) through intracellular leucine sensing. mTORC1 activated by amino acids affects the influence on physiology functions including cell proliferation, protein synthesis and autophagy
Jong Hyun Kim et al.
Nature communications, 8(1), 732-732 (2017-10-01)
Leucyl-tRNA synthetase (LRS) is known to function as leucine sensor in the mammalian target of rapamycin complex 1 (mTORC1) pathway. However, the pathophysiological significance of its activity is not well understood. Here, we demonstrate that the leucine sensor function for mTORC1
