The identification and optimization of the first activators of fast skeletal muscle are reported. Compound was identified from high-throughput screening (HTS) and subsequently found to improve muscle function via interaction with the troponin complex. Optimization of for potency, metabolic stability, and physical properties led to the discovery of tirasemtiv (), which has been extensively characterized in clinical trials for the treatment of amyotrophic lateral sclerosis.
首次报道了快速骨骼肌的首批激活剂的鉴定和优化。化合物通过高通量筛选（HTS）被鉴定出来，随后发现其通过与肌钙蛋白复合物相互作用来改善肌肉功能。对该化合物的效力、代谢稳定性和物理性质进行优化后，发现了替拉西泮（tirasemtiv），它在治疗肌萎缩侧索硬化症的临床试验中已得到广泛表征。
