In vitro
BMS-3 (Compound 2) exhibits a dose-dependent decrease in A549 human lung cancer cell viability by inducing mitotic arrest, characterized by enhanced total nuclear DNA intensity and histone H3 phosphorylation following a 24-hour exposure. It effectively inhibits these cells with an EC50 value of 154 nM[1]. Additionally, BMS-3 elucidates the role of LIMK1 in Cofilin phosphorylation; inhibition of p-LIMK by BMS-3 (1-50 μM) leads to a notable reduction in p-Cofilin levels after a 10-minute incubation under capacitating conditions, with a marked decrease in actin polymerization levels compared to the DMSO controls. Furthermore, under capacitating conditions, mouse sperm exposure to escalating concentrations of BMS-3 (0, 1, 10, and 50 μM) for 90 minutes significantly diminishes the percentage of sperm undergoing acrosomal exocytosis upon Progesterone stimulation[2], highlighting BMS-3's potential in affecting sperm functionality.
Kinase Assay
The protein kinase domains of human LIMK1 and LIMK2 are expressed as glutathione S-transferase fusion proteins using the Bac-to-Bac system in Sf9 cells. Compounds 1 to 6 (e.g., BMS-3) are assayed for inhibition of LIMK1 and LIMK2 protein kinase activity by radioactive phosphate incorporation into biotinylated full-length human destrin. Reactions are done with a concentration series of compound in 25 mM HEPES, 100 mM NaCl, 5 mM MgCl2, 5 mM MnCl2, 1 μM total ATP, 83 μg/mL biotinylated destrin, 167 ng/mL glutathione S-transferase-LIMK1, or 835 ng/mL glutathione S-transferase-LIMK2 in a total volume of 60 μL at room temperature for 30 min (LIMK1) or 60 min (LIMK2). Reactions are terminated by addition of 140 μL of 20% TCA/100 mM sodium pyrophosphate, and the precipitates are harvested onto GF/C unifilter plates. The radioactivity incorporated is determined using a TopCount after addition of 35 μL Microscint scintillation fluid[1]

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
