BTS (N-Benzyl-p-toluenesulfonamide) is a potent and selective inhibitor of skeletal muscle myosin II subfragment 1 (S1) ATPase activity, with an IC50s of ~5 μM for actin- and Ca2+-stimulated myosin S1 ATPase. BTS specifically inhibits the contraction of fast skeletal muscle fibers.
BTS (2-12 μM) inhibits the Ca2+-stimulated ATPase activity of myosin S1 in the absence of actin, with an IC50 of ~5 μM[1]. BTS (2-20 μM) reversibly inhibits the gliding motility rate of heavy meromyosin (HMM)[1]. BTS (100 μM) releases myosin from actin in the presence of ADP[1]. BTS (0-20 μM) reversibly inhibits isometric Ca2+-activated tension in skinned skeletal muscle fibres from rabbit and frog, with IC50s of ~3 μM and 1 μM, respectively[1].
