[β-Ala]-[Lys(5-TAMRA)]-acid

The renin angiotensin system (RAS) consists of many angiotensin peptides involved in regulating functions such as blood pressure, cardiovascular function and energy balance. RAS activity is elevated in obesity and RAS is widely studied in relation to lifestyle-related diseases.Angiotensin 1-7 (Ang-(1-7)) is a component of the RAS. Ang-(1-7) is produced by angiotensin-converting enzyme 2 (ACE2), from the angiotensin II (Ang-II) peptide, as well as by prolylendopeptidase (PEP) and neutral endopeptidase (NEP) which produce Ang1 7 directly from angiotensin I (Ang-I).Ang-(1-7) broadly opposes Ang-II actions. Ang-(1-7) has vasodilatory and anti-oxidative effects, and exerts protective actions in hypertension, diabetes, and other cardiovascular disorders, Ang-(1-7) therefore represents a promising therapeutic target for cardiovascular and metabolic diseases. Ang (1-7) exerts its actions via its G-protein-coupled receptor, Mas. This novel arm of the RAS has effects that counterbalance those mediated by the classical ACE/Ang-II pathway.The C-terminal proline fro this peptide is in the D enantiomer.

Galanin (1-30) is an endogenous neuropeptide with endocrine, metabolic and behavioural effects. Galanin has a role in intestinal smooth muscle contraction, insulin and somatostatin release, and synaptic neurotransmission.Galanin is widely distributed in the central nervous, peripheral, and endocrine systems. Galanin's overarching function is as an inhibitory, hyper-polarizing neuromodulator for classical neurotransmitters like acetylcholine and serotonin. Galanin interacts with 3 receptor subtypes, GalR1-3 G protein-coupled receptors inserted into the plasma membrane. GalR1 is believed to activate a Gβγ pathway to regulate MAPK activation. GalR2 can also activate the MAPK pathway, but unlike GalR1, there is detectable inositol phosphate production. GalR3 is associated with the G alpha i/o pathway receptor activation leads to a cellular influx of K+. Each receptor has been associated with neurological diseases such as GalR3 and epilepsy.Galanin protects against various physiological insults in vitro, including excitotoxicity and β-amyloid toxicity. Changes in galanin have been widely studied concerning Alzheimer's disease, and galaninergic neurons are spared in late-stage Alzheimer's relative to non-galaninergic neurones.Galanin (1-30) has been used as an agonist for the GalR2 receptor in vitro for calcium mobilisation assays to understand the role Galanin/GalR2 play in multiple sclerosis.An N-terminal cysteine residue has been included on the galanin (1-30) peptide to allow ease of site-specific conjugation to various molecules.

Optimal peptide substrate for kallikrein-related peptidase 14 (KLK14). In its intact state this peptide is not fluorescent, however when this substrate peptide is cleaved by KLK14, Rhodamine 110 is released and thus fluorescence can then be detected. This peptide therefore allows for the quantification of KLK14 peptidase activity. KLK14 is most abundant in the skin, with lower levels in breast and prostate and may form part of the protease cascade responsible for maintaining the epidermal barrier. Aberrant KLK14 proteolytic activity is linked to several skin pathologies. Overexpression of KLK14 seen in several hormone-dependent cancers, including prostate, colon, ovarian, and breast, correlating with higher risk of disease progression. Therefore KLK14 is a potential point of therapeutic intervention in a variety of pathologies.Contains rhodamine 110 group, a widely used red fluorescent tag. The terminal carboxylic acids in this peptide have been activated by the addition of the p-tosyl moiety, allowing for easy addition of functional groups or further peptide residues.
