4、onmuscle myosin IIA andIIB with IC50 values ranging from 0.5 to 5 M. Smooth muscle myosin is only poorly inhibited (IC50=80 M)1. Blebbistatin does not compete with nucleotide binding to the skeletal muscle myosin subfragment-1. Theinhibitor preferentially binds to the ATPase intermediate with ADP an

5、d phosphate bound at the active site,and it slows down phosphate release. It blocks the myosin heads in a products complex with low actin affinity2. In culture-activated hepatic stellate cells, blebbistatin is found to change both cell morphology andfunction. Stellate cells become smaller, acquire a

6、 dendritic morphology and have less myosin IIA-containingstress fibres and vinculin-containing focal adhesions. Blebbistatin impairs silicone wrinkle formation, reducescollagen gel contraction and blocks endothelin-1-induced intracellular Ca2+ release. It promotes wound-induced cell migration 3.体内研究

7、 Blebbistatin dose-dependently and completely relax both KCl- and carbachol-induced rat detrusor andendothelin-1-induced human bladder contraction. Pre-incubation with 10 M blebbistatin attenuatescarbachol responsiveness by 65% while blocking electrical field stimulation-induced bladder contractionr

At day 3, medium is replaced by serum-free mediumand cells are starved overnight, treated with or without blebbistatin (25 M) for 2 h followed by stimulationwith platelet-derived growth factor
