EDG-5506 (Sevasemten) is a potent, selective, orally active inhibitor of fast skeletal muscle myosin, inhibits fast myofibril ATPase from rabbit psoas muscle with IC50 of 0.2 uM.
EDG-5506 is inactive against cardiac and slow bovine masseter skeletal myofibrils with an IC50 greater than 100 uM.
EDG-5506 is also a potent inhibitor of other mixed fast myosin myofibrils (mouse gastroc IC50 0.4 uM, 21% IIa, 15% IIx, 56%IIb; mouse TA IC50 0.4 uM, mixed IIa, IIx, IIb suggesting equal potency against all fast skeletal myosin proteins.
EDG-5506 inhibits the enzymatic activity of fast skeletal S1 from rabbit psoas but not porcine ventricular cardiac S1 or the more unrelated smooth muscle S1 with an IC50 of 0.11 uM and >100 uM, respectively.
EDG-5506 effectively reduces dye uptake in ex vivo lengthening contraction of mdx EDL muscle using a membrane-impermeable dye.
EDG-5506 protects skeletal muscle in mdx and DBA/2 mdx mice in vivo, with no effect on body or muscle weight.
EDG-5506 lowers disease biomarkers and improves physical function in duchenne muscular dystrophy (DMD) dogs.
