Home Cell Cycle DNA/RNA Synthesis inhibitor BC-LI-0186 For research use only.

BC-LI-0186

BC-LI-0186 is a selective blocker of Leucyl-tRNA synthetase (LRS, LeuRS) and Ras-related GTP-binding protein D (RagD) interaction (LRS-RagD interaction) (IC50 = 46.11 nM) by competing against RagD for LRS VC domain binding (KD = 42.1 nM), thereby inhibiting lysosomal localization of LRS and mTORC1 activity. It also effectively suppresses the activity of cancer-associated mTOR mutants and the growth of rapamycin-resistant cancer cells.

Targets
Leucyl-tRNA synthetase [1]
(in surface plasmon resonance (SPR) analysis)		 Leucyl-tRNA synthetase [1]
(in chemical inhibition assay of the LRS–RagD interaction)

In vitro
In vitro

BC-LI-0186 binds to the RagD interacting site of LRS, thereby inhibiting lysosomal localization of LRS and mTORC1 activity. BC-LI-0186 also effectively suppresses the activity of cancer-associated MTOR mutants and the growth of rapamycin-resistant cancer cells.[1]
Cell Research Cell lines Human colon cancer cells, Human pancreatic cancer cells, Human breast cancer cells, Human ovary cancer cells, Human glioblastoma cells
Concentrations 0-20 μM
Incubation Time 15 min
Method

Cells are starved for 90 min in the leucine-free medium and then in the serum-free media for 15 min, or 1.5 h, or 6 h. And the cell lysates are analyzed with the corresponding antibodies.
In Vivo
In vivo

BC-LI-0186 (intraperitoneal injection; 50 mg/kg; alone or combines with cisplatin alone; 2 weeks; bid for 5 days per week) exhibits antitumor effects and significantly reduces tumor size compared with treatment with vehicle in an LSL K-ras G12D lung cancer animal model.[1]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
