Ribosomal protein L3 peptide (202-222) is a peptide with the sequenceH2N-Met-Ser-His-Arg-Lys-Tyr-Glu-Ala-Pro-Arg-His-Gly-His-Leu-Gly-Phe-Leu-Pro-Arg-Lys-Arg-amide, MW=2573.

[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.

Immunoglobulin M heavy chain (IGHM) fragment [Homo sapiens] is a fragment (Gly-Val-Ala-Leu-His-Arg-Pro-Asp-Val-Tyr-Leu-Leu-Pro-Pro-Ala-Arg) on the human immunoglobulin micro heavy chain. Immunoglobulins (Ig) are the antigen recognition molecules of B cell

Arg-Gly-Asp-Ser acetate is an integrin binding sequence that directly and specifically bind pro-caspase-8, pro-caspase-9 and pro-caspase-3, while it does not bind pro-caspase-1. Arg-Gly-Asp-Ser acetate inhibits integrin receptor function.

Myelin Basic Protein (MBP) (68-82), guinea pig, is a peptide with the sequence Tyr-Gly-Ser-Leu-Pro-Gln-Lys-Ser-Gln-Arg-Ser-Gln-Asp-Glu-Asn and represents a fragment of myelin basic protein (MBP).

Arg-Gly-Asp-Ser (TFA) is an integrin-binding sequence that inhibits integrin receptor function by specifically and directly binding to pro-caspase-8, pro-caspase-9, and pro-caspase-3, without interacting with pro-caspase-1 [1].

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.

Tanurmotide is a bioactive chemical.

R 715, a bradykinin B1 receptor antagonist, inhibits contractions in isolated human umbilical cords that express bradykinin B1 receptors (pA2 = 8.49). When administered at doses of 200, 400, and 600 µg/kg, R 715 enhances latency to tail withdrawal in the tail-flick test for diabetic neuropathy mouse models induced by streptozotocin (STZ), signaling potential analgesic properties. Furthermore, at a 1 mg/kg per day dosage, it mitigates symptoms in a mouse model of experimental autoimmune encephalomyelitis (EAE) induced by MOG35-55 antigen peptide, such as reducing hind limb weakness and paralysis, improving gait symmetry, and decreasing spinal inflammation, neuron demyelination, and lesion monocyte invasion. Additionally, R 715 at 0.01 nmol/animal, administered intracerebroventricularly (i.c.v.), lowers mean arterial blood pressure and increases heart rate in spontaneously hypertensive rats, indicating cardiovascular effects.
