| 背景说明 | 2,3-Butanedione monoxime是一种肌球蛋白 ATP 酶 (myosin ATPase) 抑制剂。2,3-Butanedione monoxime也是一种骨骼肌肌球蛋白 II（myosin-II）的非竞争性抑制剂。2,3-Butanedione monoxime诱导肌质网 Ca2+ 释放。 |
| 生物活性 | Biacetyl monoxime (Diacetyl monoxime)， a myosin ATPase inhibitor， is a skeletal and cardiac muscle contraction inhibitor. Biacetyl monoxime is also a well-characterized non-competitive inhibitor of chemical and motile activity of skeletal muscle myosin-II. Biacetyl monoxime induces sarcoplasmic reticulum Ca2+ release[1-3]. |
| In Vitro | Biacetyl monoxime(50 mM，2 and 4 h)disrupts the localization of the Golgi apparatus，but not that of the endoplasmic reticulum[1].Biacetyl monoxime(0-30 mM)induces SR Ca2+ release(no efflux inhibitors)in a concentration-dependent manner，with a maximal reduction of 72% of SR Ca2+ at pCa 6.0.Biacetyl monoxime acts as a chemical phosphatase，which has led to speculation that dephosphorylation of key Ca2+ channel proteins may be involved in its inhibition of contraction[2].Biacetyl monoxime does not inhibit the ATPase activity of two different myosin-I isoforms，myosin-V，or myosin-VI[3]. |
