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.

C-101 targets muscle cells by using a carnitine carrier molecule and inhibits calpain by attaching a leupeptin analogue onto the carrier. Leupeptin has been studied extensively in a variety of animal models and was shown to be an effective means of slowing or delaying muscle wasting. Carnitine is a compound present in skeletal muscle involved in the transfer of fatty acids across mitochondrial membranes. In C-101, the carnitine carrier molecule directs the leupeptin analogue into targeted cells where it inhibits the up-regulation of calpain. Therefore, by targeting a calpain inhibitor to muscle cells, it is believed that C-101 will prevent the degradation and promote the preservation of functional muscle.
Investigated for use/treatment in muscular dystrophy.
