Within the brain, DSIP is particularly abundant in the hypothalamus, hippocampus, and limbic regions, where it interacts with multiple peptide and non-peptide mediators, including corticotropin-like intermediate peptide (CLIP), adrenocorticotrophic hormone (ACTH), melanocyte-stimulating hormone (MSH), and melanin-concentrating hormone (MCH)
Thiols (such as sulfur bearing compounds ALA, NAC, DMSA, DMPS, Glutathione) cause different reactions usually due to slow SUOX function and other downstream metabolic issues in the processing of the sulfites
Additionally, peptides that have been lyophilized must be kept at low temperatures in order to avoid degradation during the reconstitution process
Notably 16 , devoid of a macrocyclic ring system in the N-terminal is not selective and inhibits both IRAP and AP-N activity, suggesting that introduction of proper conformational constrains in the N-terminal by macrocyclization improves selectivity (Axn et al., 2007)
