Oleoyl-Gly-Lys-(m-PEG11)-NH2 is a PEG-lipid compound that features an oleoyl amide linked to a glycine-lysine dipeptide, with a methoxy PEG11 chain attached at the C-terminus of lysine. The primary amine of lysine facilitates reactions with carboxylic acids, NHS esters, and carbonyl groups. The PEG linker enhances water solubility.

[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.

Body Protection Compound 157 (BPC 157) is a pentadecapeptide derived from BPC, identified in gastric juice, exhibiting diverse biological activities. At 2 µg/ml, BPC 157 enhances primary rat tendon fibroblast cell migration and F-actin formation. Furthermore, doses of 0.01 and 10 µg/kg, intraperitoneally (i.p.), mitigate paw swelling, bone erosion, and mononuclear cell infiltration in the joints of rats with rheumatoid arthritis induced by complete Freund's adjuvant (CFA). It also diminishes gastric ulcer size in rats caused by indomethacin, aspirin, or diclofenac at these doses. Additionally, BPC 157 reduces catalepsy duration and tremor severity in a mouse model of Parkinson's disease triggered by MPTP.

'N'-Boc-N-(Gly-Oleoyl)-Lys is an alkyl chain-derived proteolysis targeting chimera (PROTAC) linker, suitable for PROTAC synthesis [1].

Levitide is a neurohormone-like peptide which is from the skin of Xenopus laevis.

Troponin I is a cardiac and skeletal muscle protein useful in the laboratory diagnosis of a heart attack. Troponin I is a part of the troponin protein complex, where it binds to actin in thin myofilaments to hold the actin-tropomyosin complex in place.

Felypressin (Octapressin) is a synthetic analog of LYPRESSIN with a PHENYLALANINE substitution at residue 2. Felypressin is a vasoconstrictor with reduced antidiuretic activity.

Felypressin acetate (PLV-2) is an agonist of vasopressin 1 and acts on all arginine vasopressin receptors 1AS. Felypressin acetate can be used in dental procedures.

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.
