Vilon peptide was developed in the 1990s by researchers at the Institute of Immunology in Moscow, Russia. The development of Vilon was part of a broader research program aimed at developing novel immunomodulatory peptides. The researchers were particularly interested in peptides that could regulate the activity of T-cells, a type of white blood cell that plays...

Liraglutide peptide is a synthetic analog of glucagon-like peptide-1 (GLP-1), and it was developed to activate the GLP-1 receptor, increasing insulin secretion, decreasing glucagon secretion, and slowing gastric emptying.  Liraglutide has the following sequence: H-His-Ala-Glu-Gly-Thr-Phe-Thr-Ser-Asp-Val-Ser-Ser-Tyr-Leu-Glu-Gly-Gln-Ala-Ala-Lys(γ-Glu-palmitoyl)Glu-Phe-Ile-Ala-Trp-Leu-Val-Lys-Gly-Arg-Gly-OH. The modification in Liraglutide peptide is the addition of a fatty acid chain (palmitic acid) to the amino acid lysine, in position 26 of...

Modified GRF (1-29) is a peptide hormone that is also known as CJC-1295 without DAC (Drug Affinity Complex). It is a synthetic analog of growth hormone-releasing hormone (GHRH) and is designed to increase natural production of growth hormone. Similarly to other GHRH analogs, it appears to work by binding to the growth hormone-releasing hormone receptor in...

ARA-290 peptide is a small, synthetic peptide is a derivative of erythropoietin (EPO), a hormone that is considered to stimulate the production of red blood cells. However, unlike EPO, ARA-290 does not appear to affect erythropoiesis and has been suggested to exhibit tissue-protective characteristics. In this article, we will explore what ARA-290 peptide is, how...

Sermorelin Acetate, a synthetic peptide, was developed to function as an analog of a naturally occurring hormone called growth hormone-releasing hormone (GHRH). While GHRH has 44 amino acids, Sermorelin peptide is truncated down to 29 amino acids. Sermorelin peptide is also known as the Growth Hormone Releasing Factor (1-29) or GRF (1-29). Sermorelin is the...

Peptides consist of chains of amino acids that may play a crucial role in many biological processes. One such peptide, MOTS-c (mitochondrial ORF of the 12S rRNA type-c), has recently emerged, found in mitochondria, which is considered the powerhouse of the cell. This peptide is encoded in the mitochondrial genome and appears to be able...

Ipamorelin, also known as NNC 26-0161, is a pentapeptide with the amino acid sequence Aib-His-D-2-Nal-D-Phe-Lys-NH2. Researchers suggest it may induce a peak in growth hormone (GH) synthesis by the pituitary gland via activating the growth hormone secretagogue receptors (GHS-Rs). In this respect, Ipamorelin is classified as a growth hormone secretagogue (GHS). It appears mimic the...

BPC-157 is a pentadecapeptide made of 15 amino acids and bears the sequence Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val, and a molecular formula of C62H98N16O22. This is a fully synthetic peptide with a sequence not known to occur in nature. However, it is often termed a “gut peptide,” as it is suggested to have similar structure and properties to other...

  Scientists have created IGF-1 LR3 peptides by modifying the amino acid sequence of IGF-1. The new peptide has similar potential but possibly higher potency and improved stability. The LR3 in the name describes the two modifications to the IGF-1 molecule. Long R3 IGF-1, or IGF-1 LR3, is an analog of insulin-like growth factor 1...
