[Leu144,Arg147]-PLP (139-151) is a mutated fragment of the myelin proteolipid protein (PLP), featuring substitutions of tryptophan to leucine and histidine to arginine at positions 144 and 147, respectively. Immunizing mice with this peptide (50 µg) mixed in complete Freund’s adjuvant (CFA) elevates IL-4 levels in the spleen. While it suppresses Th1 cell activation in vitro, it does not do so in vivo; instead, it promotes the development of regulatory T cells. Preimmunization with [Leu144, Arg147]-PLP (139-151) postpones the onset of experimental autoimmune encephalomyelitis (EAE) triggered by encephalitogenic peptides from PLP (178-191), myelin oligodendrocyte glycoprotein (MOG) (92-106), or myelin basic protein (MBP) in mice.

C111 Peptide is a peptide.

Tiger17, a cyclic peptide derivative of tigerinin-RC1 and tigerinin-RC2—antimicrobial peptides from the crab-eating frog (F. cancrivora) skin secretions—enhances HaCaT keratinocytes and human skin fibroblasts proliferation at 5 to 20 µg/ml concentrations, and promotes HaCaT cell migration at 20 µg/ml. Additionally, Tiger17 augments RAW 264.7 macrophages' recruitment and secretion of TGF-β1 and IL-6. When topically applied at 20 µg/ml, it accelerates wound closure and re-epithelialization in a mouse model of full-thickness dermal wounds.

Protirelin (Thyroliberin) is a tripeptide that stimulates the release of thyrotropin and prolactin.

Pro-Adrenomedullin(153-185),human, (C143H224N42O43), a peptide with the sequence H2N-SLPEAGPGRTLVSSKPQAHGAPAPPSGSAPHFL-OH, MW= 3219.6. Adrenomedullin (AM) is a ubiquitously expressed peptide initially isolated from phaechromyctoma in 19931. AM was initially identified as a vasodilator, some have cited this as the most potent endogenous vasodilatory peptide found in the body2. Differences in opinion regarding the ability of AM to relax vascular tone arises from the differences in the model system used3. Other effects of AM include increasing the tolerance of cells to oxidative stress and hypoxic injury and angiogenesis. AM is seen as a positive influence in diseases such as hypertension, myocardial infarction, chronic obstructive pulmonary disease and other cardiovascular diseases, whereas it can be seen as a negative factor in potentiating the potential of cancerous cells to extend their blood supply and cause cell proliferation.
