Product Data
Biological target:
Reldesemtiv is a selective, orally active and next-generation fast skeletal muscle troponin activator (FSTA). Reldesemtiv selectively activates fast skeletal myofibrils with an EC50 of 3.4 μM.
In vitro activity:
While not specific to reldesemtiv, this article review both repurposed drugs and small-molecule compounds discovered, one being reldesemtiv, following medicinal chemistry optimization for the potential treatment of spinal muscular atrophy. Reference: J Med Chem. 2016 Nov 23;59(22):10067-10083. https://pubmed.ncbi.nlm.nih.gov/27490705/
In vivo activity:
Reldesemtiv substantially increases exercise performance in rats exhibiting heart failure-mediated skeletal myopathy. These results suggest that the modulation of skeletal muscle function by a fast skeletal troponin activator may be a useful therapeutic in heart failure-associated exercise intolerance. Reference: J Pharmacol Exp Ther. 2015 Apr;353(1):159-68. https://pubmed.ncbi.nlm.nih.gov/25678535/
