collagen 1

This is a peptide inhibitor of collagen fibrillar matrix assembly.

Collagen type IV alpha1 (531-543) is a protein that in humans is encoded by the COL4A1 gene on chromosome 13. It is ubiquitously expressed in many tissues and cell types. COL4A1 is a subunit of type IV collagen and plays a role in angiogenesis.

Angiotensin II human TFA is a potent vasoconstrictor in the renin-angiotensin system that regulates blood pressure through interactions with AT1R and AT2R receptors. It activates sympathetic nerve activity, promotes aldosterone synthesis and renal function, induces proliferation of vascular smooth muscle cells, and enhances type I and III collagen production in fibroblasts, leading to vascular and myocardial thickening and fibrosis. It also triggers apoptosis and promotes capillary formation, making it suitable for establishing models of cardiac hypertrophy, hypertension, and abdominal aortic aneurysm.

GRGESP, a collagen gel contraction inhibitor, impedes human fibroblast spreading within collagen gels and significantly reduces gel contraction, making it a valuable agent for research in connective tissue morphogenesis [1].

H-Pro-Gly-Pro-OH, a collagen-derived matrikine, traditionally acts as a neutrophil chemoattractant, guiding these cells to target locations to orchestrate localized repair responses. Additionally, this compound initiates the transcription of neurotrophins and their receptor genes following cerebral ischemia [1] [2].

YYRADDA, a polypeptide, enhances collagen production within the skin's extracellular matrix, thus improving skin appearance and aiding the repair of damaged skin [1].

Vitronectin, a multifunctional glycoprotein found in blood and the extracellular matrix, interacts with glycosaminoglycans, collagen, plasminogen, and the urokinase-receptor, in addition to stabilizing the inhibitory conformation of plasminogen activation inhibitor-1. It is utilized in research related to wound healing and tumor progression [1].

Tetrapeptide-4 is a peptide commonly incorporated into skincare formulations for its anti-aging benefits, which include diminishing wrinkles and fortifying collagen, elastin, and fibronectin [1].

Osteostatin, derived from parathyroid hormone-related protein (PTHrP) 107-111, has demonstrated properties conducive to bone repair in animal models presenting with bone defects and exhibits efficacy in mitigating bone erosion associated with inflammatory arthritis. Additionally, it possesses the capacity to inhibit both collagen-induced arthritis and direct osteoclastic bone resorption, marking its potential utility in inflammation and immunology research [1] [2] [3] [4].

H-Gly-Pro-Hyp-OH is a potent and orally available anti-photoaging collagen peptide that attenuates inflammation and reduces MMP-1 and MMP-3 levels; attenuates H2O2-induced aging of dermal fibroblasts; restores cortisol-mediated inhibition of type I collagen and GR activation and (TGF)-β signaling signaling, among other things; and improves the hydration of human skin, elasticity and anti-wrinkle properties.

Endotrophin (Mus musculus), a cleavage product of collagen 6 (Col6), induces upregulation of profibrotic and proinflammatory genes [1].

Caprooyl-tetrapeptide-3 acetate, employed for diminishing fine lines and wrinkles, enhances collagen VII and laminin-5 expression in corticoid-induced skin aging models [1].

Angiotensin II human acetate is a key vasoconstrictor peptide in the renin-angiotensin system. It regulates blood pressure by binding to AT1R and AT2R receptors, stimulates the sympathetic nervous system, promotes aldosterone synthesis and renal function, induces vascular smooth muscle cell proliferation and collagen synthesis, leading to vascular and myocardial hypertrophy and fibrosis, while also promoting apoptosis and endothelial capillary formation. It is commonly used to induce hypertension and cardiac hypertrophy models.

PalMitoyl Tripeptide-1 affects the synthesis of collagen, fibronectin and hyaluronic acid in human skin fibroblasts and can be used to prepare anti-aging cosmetics.

PalMitoyl Tripeptide-1 hydrochloride (PalMitoyl Tripeptide-1 hydrochloride (147732-56-7 Free base)) has effects on the synthesis of collagen, fibronectin and hyaluronic acid in human skin fibroblasts, and can be used in the preparation of anti-aging cosmetics.

Tetrapeptide-11 is the reaction product of Acetic Acid and tetrapeptide-11, containing leucine, proline, and tyrosine residues. It boosts cell growth, Syndecan-1, and Collagen XVII synthesis. Tetrapeptide-11 has a face and body anti-wrinkle and anti-aging
