L-Aminocarnityl-succinyl-leucyl-argininal-diethylacetal
C-101, also called Myodur, is developed for the treatment of Duchenne’s muscular dystrophy (DMD) which is a morbid genetic disease that can lead to death in late adolescence due to accelerated skeletal muscle breakdown. C-101 includes a carnitine carrier molecule and a leupeptin analogue, a known calpain inhibitor. Calpain is the primary protease that degrades skeletal muscle.
