<p>Ac-Phe-Lys-OH is a synthetic peptide that mimics the lysine side chain of L-lysine. It has been shown to be cytotoxic to cancer cells and cardiac cells, with the formation rate of Ac-Phe-Lys-OH being dependent on the concentration of glycolaldehyde. The reaction yield for Ac-Phe-Lys-OH is also dependent on creatine kinase activity. Acetylation of Ac-Phe-Lys-OH reduces its cytotoxicity and increases its solubility in water.</p>

<p>Angiotensin I/II (3-8) H-Val-Tyr-Ile-His-Pro-Phe-OH is a peptide that has physiological effects and is used as a drug. It is an active analogue of the peptide hormone angiotensin II, which regulates blood pressure and fluid volume. Angiotensin I/II (3-8) H-Val-Tyr-Ile-His-Pro-Phe-OH binds to angiotensin receptors and stimulates the release of calcium ions from cytosolic stores in cells, leading to increased muscle contractions and vasoconstriction. This drug may also have effects on dopamine levels in the brain, locomotor activity, and biochemical properties such as enzyme activity or protein binding.br&gt;<br>Angiotensin I/II (3-8) H-Val-Tyr-Ile-His Pro Phe OH has been shown to reduce the level of dopamine</p>

<p>H-Leu-Pro-Pro-OH is a synthetic tripeptide that has been shown to increase endothelial function in humans. The peptide is thought to work by increasing nitric oxide production and by inhibiting angiotensin II production. H-Leu-Pro-Pro-OH also reportedly increases uptake of glucose in the intestine and decreases blood pressure. In placebo-controlled, crossover studies, H-Leu-Pro-Pro-OH increased plasma concentrations of angiotensin I and II, suggesting that it may be a potent inhibitor of angiotensin converting enzyme (ACE).</p>

<p>Z-Phe-Cit-AMC is a fluorescent substrate for the enzymes cysteine and peptide aminopeptidases. It has been synthesized by conjugating 7-amino-4-methylcoumarin with L-phenylalanine. The product is useful in assays to measure the activity of these enzymes, which are involved in protein digestion and wound healing. Z-Phe-Cit-AMC can be hydrolyzed by bromelain, ficin, or papain and it can be used as a substrate for enzyme reactions.</p>
