IC50: 0.7 nM (BTK)[1]

ln Vitro |
BTK inhibition is a successful strategy against cancers of the B cell[1]. With an IC50 value of 2.6 nM, BTK-IN-15 (compound 42) exhibits inhibitory activity against TMD8[1]. With 0.05% and 44% of the control, respectively, BTK-IN-15 (1 μM; 1 h) shows notable selectivity to BTK over EGFR kinase[1]. BTK-IN-15 (0-1 mM; 72 h) has an IC50 value of 1.7 nM and demonstrates strong anti-proliferative action against the human mantle cell lymphoma cell line (REC-1)[1]. BTK-IN-15 (0-1 mM; 2 h) has an IC50 value of 1.49 nM[1], which inhibits BTK auto-phosphorylation. BTK-IN-15 (0–100 nM; 48 h) stops the cell cycle at the G1 phase, and in TMD8 (0–1 mM; 72 h), it causes apoptosis[1]. Low cardiotoxicity is shown by BTK-IN-15's low hERG channel activity (IC50=4.38 μM)[1].

ln Vivo |
At a dosage of 50 mg/kg in mice, BTK-IN-15 (compound 42) (12.5-50 mg/kg; po; twice daily; 21 d) suppresses tumor growth (TGI = 104%)[1]. In mice, BTK-IN-15 (300, 400, and 500 mg/kg; po; twice daily; 14 d) exhibits no effect on body weight when compared to control[1]. It is biologically safe. Mice treated with BTK-IN-15 (10 mg/kg; po) exhibit a high oral bioavailability of 40.98%[1].

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.
