LFM-A13 is a novel and potent inhibitor of BTK, JAK2, PLK with anticancer effects. It inhibits recombinant BTK, Plx1 and PLK3 with IC50s of 2.5 μM, 10 μM and 61 μM.
| Targets |
Plx1 (IC50 = 10 μM); PLK3 (IC50 = 61 μM); BRK (IC50 = 267 μM); BMX (IC50 = 281 μM); FYN (IC50 = 240 μM); Hepatocyte growth factor receptor kinase (Met) (IC50 = 215 μM (IC50); BTK (IC50 = 2.5 μM)

| ln Vitro |
LFM-A13 (100 μM; 4 h) inhibits Epo-induced phosphorylation of EpoR, JAK2, BTK, STAT5 and ERK1/2 in R10 cells [2]. LFM-A13 (100 μM; transfected 48 h) inhibits COS cells. LFM-A13 effectively inhibits Plx1 with an IC50 of 10 μM. It also inhibits BRK, BMX, FYN and Met with an IC50 of 267 respectively.Cell lines : PTK1 cell concentration: 100 μM Incubation time: 2 h Results: Significantly inhibited cycle progression. 281, 240 and 215 μM[3].

| ln Vivo |
LFM-A13 (10 or 50 mg/kg; intraperitoneal injection) revealed dose-dependent anti-tumor effects in the MMTV/Neu treatment regimen [3]. FM-A13 (50 mg/kg; three times a week; intraperitoneal injection) can reduce DMBA-induced mammary gland growth in mice via modulating a number of cell cycle, persistence and associated variables [4].

| Enzyme Assay |
For HCK kinase assays, we used HCK-transfected COS-7 cells. The cloning and expression of HCK in COS-7 cells has been described previously. The pSV7c-HCK plasmid was transfected into 2 × 106 COS-7 cells using LipofectAMINE, and the cells were harvested 48 h later. The cells were lysed in Nonidet P-40 buffer, and HCK was immunoprecipitated from the whole cell lysates with an anti-HCK antibody.[1]
LFM-A13, or alpha-cyano-beta-hydroxy-beta-methyl-N-(2,5-dibromophenyl)propenamide, was shown to inhibit Bruton's tyrosine kinase (Btk). Here we show that LFM-A13 efficiently inhibits erythropoietin (Epo)-induced phosphorylation of the erythropoietin receptor, Janus kinase 2 (Jak2) and downstream signalling molecules. However, the tyrosine kinase activity of immunoprecipitated or in vitro translated Btk and Jak2 was equally inhibited by LFM-A13 in in vitro kinase assays. Finally, Epo-induced signal transduction was also inhibited in cells lacking Btk. Taken together, we conclude that LFM-A13 is a potent inhibitor of Jak2 and cannot be used as a specific tyrosine kinase inhibitor to study the role of Btk in Jak2-dependent cytokine signalling.[2] |

| Animal Protocol |
Animal/Disease Models: MMTV/neu transgenic mouse model [3]
Doses: 50 or 100 mg/kg Route of Administration: intraperitoneal (ip) injection; twice a day, 5 days a week. Experimental Results: Reduce the formation of mammary gland tumors in mice. Animal/Disease Models: DMBA-induced breast cancer mouse model [4] Doses: 50 mg/kg (or combined with paclitaxel (10 mg/kg; intraperitoneal (ip) injection once a week)) Route of Administration: intraperitoneal (ip) injection; weekly 3 Experimental Results: Inhibition of DMBA-induced mammary tumor incidence, average tumor number, average tumor weight and size in balb/c (Bagg ALBino) mouse. Dramatically diminished the expression of PLK1, cyclin D1, CDK-4, P53 and Bcl-2, but increased the expression of p21, IκB, Bax and caspase 3 in mice. |

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
