4、549 humanlung cancer cells. BMS-3 inhibits A549 human lung cancer cells with EC50 value of 154 nM 1. BMS-3 isused to demonstrate the direct participation of LIMK1 in the phosphorylation of Cofilin. Inhibition of p-LIMKwith 1-50 M of BMS-3 results in a dose-dependent decrease of p-Cofilin after 10 mi

5、n incubation incapacitating conditions. As a control, sperm are also incubated for 10 min under non-capacitating conditionswhich result in low levels of p-Cofilin. In the presence of 1 or 50 M of BMS-3, actin polymerization levels aresignificantly lower compared to controls (DMSO). Mouse sperm are i

6、ncubated under capacitating conditionsfor 90 min in the presence or absence of increasing concentrations of p-LIMK inhibitor BMS-3 (0, 1, 10 and50 M). The increasing concentrations of BMS-3 result in a strong decrease on the percentage of sperm thatundergoes acrosomal exocytosis after stimulation wi

7、th 20 M of Progesterone 2.PROTOCOLKinase Assay 1 The protein kinase domains of human LIMK1 and LIMK2 are expressed as glutathione S-transferase fusionproteins using the Bac-to-Bac system in Sf9 cells. Compounds 1 to 6 (e.g., BMS-3) are assayed for inhibitionof LIMK1 and LIMK2 protein kinase activity

8、 by radioactive phosphate incorporation into biotinylated full-lengthhuman destrin. Reactions are done with a concentration series of compound in 25 mM HEPES, 100 mMNaCl, 5 mM MgCl2, 5 mM MnCl2, 1 M total ATP, 83 g/mL biotinylated destrin, 167 ng/mL glutathione S-transferase-LIMK1, or 835 ng/mL glut

9、athione S-transferase-LIMK2 in a total volume of 60 L at roomtemperature for 30 min (LIMK1) or 60 min (LIMK2). Reactions are terminated by addition of 140 L of 20%TCA/100 mM sodium pyrophosphate, and the precipitates are harvested onto GF/C unifilter plates. Theradioactivity incorporated is determin
