DDC and neurodegenerative disease: The proteins found in Nosustrophine regulate several cellular pathways, some of them related to neurodegenerative diseases such as Huntington’s disease (actin, calpain and tubulin), AD (presenilins), and Parkinson’s disease (dopamine receptor-mediated signaling pathway with proteins such as aromatic L-amino acid decarboxylase, catechol-O-methyl transferase, monoamine oxidase, protein kinase A and dopamine and cAMP-regulated phosphoproteins) (Figure 1C).
