Description Tirasemtiv (CK-2017357)(CK 2017357) is a small-molecule fast-skeletal-troponin activator, with a potential treatment for muscle weakness and neuromuscular dysfunction.
In vitro Tirasemtiv 是一种快速骨骼肌肌钙蛋白激活剂,通过增敏肌原纤维对钙的反应来发挥作用;这种机制能够在神经输入减少时,放大肌肉对神经肌肉输入的响应,产生更大的力量。Tirasemtiv 选择性地增敏快速骨骼肌肌钙蛋白对钙(Ca2+)的反应,并减缓了快速骨骼肌调节性肌钙蛋白复合体释放Ca2+的速率[1]。
In vivo 单次剂量的Tirasemtiv显著提高了携带B6SJL-SOD1 g93A基因的ALS功能缺陷雌性转基因小鼠的亚最大等长力量、前肢握力、格子悬挂时间和旋转木马表现。此外,经Tirasemtiv处理的B6SJL-SOD1 g93A雌鼠的膈肌力量和潮气量显著增加。在达到25%缺陷里程碑时,接受载体处理的B6SJL-SOD1 g93A小鼠前肢握力为49.6±4.6g。Tirasemtiv使握力增加38%,达到68.6±8.1g(p<0.05,单尾t检验)。以大约20分钟间隔给予Tirasemtiv剂量2, 2, 2, 和4 mg/kg,以实现累积剂量10 mg/kg。对数剂量与反应关系的回归分析表明,Tirasemtiv显著增加了荒漠型及B6SJL-SOD1 g93A中期小鼠的肌力(WT p<0.0001; 中期 p=0.0028)。在疾病的后期阶段,与基线相比,小鼠显示出因Tirasemtiv处理而肌肉功能增强的趋势(p=0.064)[1]。
