Description of Lck-IN-5

Lck-IN-5 (example C10) is a potent and selective lymphocyte-specific protein tyrosine kinase ( LCK ) inhibitor. Lck-IN-5 selectively disrupts the interaction between the SH3 domain of LCK and the RK motif of CD3ε, thereby impairing LCK recruitment to the TCR. Lck-IN-5 modulates the activity of CD3ε-containing CAR and TRuC T cells, attenuating cytokine production and promoting a central-memory-like phenotype associated with enhanced persistence. Lck-IN-5 can be used for autoimmune diseases and graft-versus-host disease research [1].

Calculation results:

Working concentration: mg/ml;

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 saline, 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.
3. All of the above co-solvents are available for purchase on the GlpBio website.
