  • Patent number: 10961273
    Abstract: Disclosed are methods of making elamipretide (MTP-131), a peptide compound with therapeutic potential for treating various mitochondrial myopathies. The synthesis of the peptide can be achieved via the use of N-carboxyanhydride-modified amino acid residues, which increases the efficiency of the synthetic process and the purity of the peptide product generated.
