Biological Activity

Description LFM-A13 is a specific Bruton's tyrosine kinase (BTK) inhibitor with IC50 of 2.5 μM, >100-fold selectivity over other protein kinases including JAK1, JAK2, HCK, EGFR,and IRK.
Targets
BTK [1]
(cell-free assay)
1.4 μM(Ki)
In vitro
In vitro

In BCL-1 cells, NALM-6 cells, or normal BALB/c splenocytes, LFM-13 inhibits the enzymatic activity of BTK in BCL-1 cells without affecting the BTK protein expression levels [2] In human neutrophils, LFM-A13 decreases the tyrosine phosphorylation induced by fMet-Leu-Phe and inhibits the production of superoxide anions and the stimulation of adhesion, chemotaxis, and phospholipase D activity. [3]

In Vivo
In vivo

In BALB/c mice bearing BCL-1 leukemia, combination of LFM-A13 (50 mg/kg/day i.p.) and the standard triple-drug VPL prolongs the median survival time. [2] In primary myeloma-bearing SCID-rab mice, LFM-A13 inhibits osteoclast activity, prevents myeloma-induced bone resorption and suppresss myeloma growth. [4]

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.
