Adrenomedullin , human

Adrenomedullin (AM) (22-52), human acetate is an antagonist of calcitonin generelated peptide receptor in the hindlimb vascular bed of the cat and an adrenomedullin receptor.

Adrenomedullin (22-52) is a C-terminal fragment of adrenomedullin (1-52) . In vitro, adrenomedullin (22-52) reduces basal corticosterone production in a mixture of rat adrenocortical and adrenomedulllary cells. It also reverses increases in ACTH-stimulated corticosterone production induced by adrenomedullin (1-52). Adrenomedulin (22-52) (0.5 and 5 μg/kg/min) has no effect on basal regional cerebral blood flow but reverses increases in regional cerebral blood flow induced by rat adrenomedullin in rats. Unlike adrenomedullin (1-52), adrenomedullin (22-52) has no effect on mesenteric arterial perfusion pressure in cats.

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.

Adrenomedullin (13-52) is a truncated form of adrenomedullin (1-52) . It induces nitric oxide-dependent relaxation of and inhibits release of angiotensin II and endothelin-1 from isolated rat aorta. In vivo, adrenomedullin (13-52) decreases mean arterial pressure (MAP) in spontaneously and renal hypertensive rats in a dose-dependent manner. Adrenomedullin (13-52) (10-3,000 ng per animal) reverses increases in lobar arterial pressure induced by U-46619 in a dose-dependent manner in cats but has no effect on basal lobar arterial pressure or systemic arterial pressure. It also potentiates inflammatory edema and neutrophil accumulation in rats.

Adrenomedullin (16-31), human TFA, a fragment containing amino acid residues 16-31 of human adrenomedullin (hADM), demonstrates significant CGRP1 receptor affinity and exhibits pressor activity in the rat systemic vascular bed while lacking this effect in cats [1].

Adrenomedullin (AM) (1-52), human (TFA), is an NH2-terminal truncated adrenomedullin analogue that influences cell proliferation and angiogenesis in cancer.

Adrenomedullin (AM) (1-52), human, is a 52-amino acid peptide that modulates cellular proliferation and angiogenesis in cancer.

Adrenomedullin (AM) (22-52), human [22-52-Adrenomedullin human], TFA, is a C-terminal truncated analogue of adrenomedullin and acts as an adrenomedullin receptor antagonist.

Adrenomedullin (ADM) is a 52-aa hypotensive peptide. Adrenomedullin (ADM) has structural similarity with amylin.

Adrenomedullin (16-31), human, is an amino acid residues 16-31 fragment of human adrenomedullin (hADM).

Adrenomedullin (13-52) is a 40 amino acid peptide with one intramolecular disulfide bridge, Adrenomedullin (13-52) is a high affinity ligand for the adrenomedullin receptor.

Adrenomedullin (AM) (1-12), human, is a peptide with the sequence Tyr-Arg-Gln-Ser-Met-Asn-Asn-Phe-Gln-Gly-Leu-Arg. Adrenomedullin (AM) (1-12), human, was initially identified as a vasodilator, and as such, it has the ability to relax vascular tone. Other

Adrenotensin (human) (Pro-ADM-153-185 (human)), a 153-185 fragment of the Adrenomedullin precursor peptide, is a 52-amino acid peptide from the CGRP superfamily that plays a diverse role in vasodilation [1].

PAMP-12(human, porcine) TFA, a significant constituent of immunoreactive (ir)-PAMP, derives from the adrenomedullin precursor and functions as a potent hypotensive peptide involved in cardiovascular regulation [1].
