H-Gly-Gly-Glu-OH is a hydrolysate of the proteasome peptide. It has reversed-phase and liquid chromatography properties, which make it a useful biochemical tool for the analysis of proteins. The carboxylate group at the end of H-Gly-Gly-Glu-OH can be used as an isopeptide to determine the sequence of peptides that are synthesized by a prokaryotic or eukaryotic cell. H-Gly-Gly-Glu-OH can also be used to cleave ligation products in order to analyse them.

H-Pro-Ser-Hyp-Gly-Asp-Trp-OH is a cyclic hexapeptide with a high activity against platelets. It is an antagonist of the cyclic RGD sequence, which is present in fibrinogen, fibronectin, vitronectin and other proteins. This peptide binds to the n-terminal residue of these proteins and prevents them from binding to their receptors on the surface of platelets. H-Pro-Ser-Hyp-Gly-Asp-Trp-OH has been shown to be specific for human platelets and does not bind to erythrocytes or leukocytes.

4-Iodo-1-methyl-1H-imidazole is a trifluoroethylamine that inhibits the activity of tyrosine kinases. It binds to the active site of tyrosine kinase and prevents the binding of ATP, preventing phosphorylation and activation of downstream substrates. 4-Iodo-1-methyl-1H-imidazole has been shown to inhibit the proliferation of tumor xenografts in mice, as well as inhibiting headgroup binding and cellular proliferation in vitro. This agent also has a nanomolar range and high selectivity for protein kinases, which may make it suitable for therapeutic purposes.

Z-Phe-Leu-OH is a protease inhibitor that belongs to the group of peptidyl-protease inhibitors. It inhibits the activity of a wide range of proteases and is specifically active against carboxypeptidases A and B. Z-Phe-Leu-OH has been shown to be specific for these enzymes, with no inhibitory activity against other proteases such as aminopeptidases, serine proteases, or metalloproteases. The amino acid composition of this protease inhibitor is different from other inhibitors that have been studied in detail. This agent was found to be more effective than phenylmethylsulfonyl fluoride (PMSF) at inhibiting carboxypeptidase A and B.
Z-Phe-Leu-OH has been shown to be an acidic compound with a pKa of 5.5; however, it does not react with chloromethyl ketone

H-Trp-Ala-OH is a synthetic amino acid that has been used as an analytical reagent. The compound has shown antihypertensive activity in animal studies and can be used to prepare samples for chromatography or spectrophotometry. H-Trp-Ala-OH is soluble in water, but not in ethanol or ether. It has a neutral pH, and the carbonyl group makes it spontaneously fluorescent.

Guanidine is a guanidinium cation that is used in the treatment of autoimmune diseases, cancer, and aspartyl receptor activity. Boc-guanidine is an efficient method for the synthesis of guanidine. It has been shown to be effective in treating inflammatory diseases and neutral pH conditions. Boc-guanidine inhibits glycogen synthase kinase-3 (GSK3) and membrane interactions, which are associated with a number of human disorders. It also has antimicrobial properties against marine microorganisms.

supplied as the trifluoroacetate salt.

FA-Ala-Phe-NH2 is a synthetic, hydrophobic peptide that mimics the structure of a spermatozoal regulatory protein. It has been shown to be an irreversible metal chelator and is used as a substrate in assays for metalloendopeptidases. In vitro studies have also shown that this peptide interacts with lectins and can inhibit the binding of spermatozoa to egg zona pellucida.

Trt-Cys(Trt)-OH is a selective dicyclohexyl carbodiimide reagent for the synthesis of amides from carboxylic acids. It is used as an intermediate in the synthesis of glutathione and other nitrogen-containing compounds. Trt-Cys(Trt)-OH reacts with hydrochloric acid to form a salt, which can be saponified to release the desired product. The hydrochloric acid converts the ester into a carboxylic acid, while the amine group on the glycine reacts with the carboxylic acid to form an amide. Trityl is also produced during this reaction, which can be removed by reduction with hydrogen gas and palladium on charcoal.

H-Asp-Arg-Val-Tyr-Ile-His-Pro-Phe-His-Leu-Val-Ile-His (Daprodinam) is a peptide that binds to the response element in the promoter region of the gene encoding for the LDL receptor. Daprodinam inhibits atherosclerosis and has been shown to have an inhibitory effect on angiotensinogen production, which leads to decreased blood pressure. Daprodinam also has inhibitory properties against toll like receptor 4, which is involved in inflammatory bowel disease.

Z-Phe-Leu-Ala-OH is a homologous protein that has been shown to have proteolytic activity. It has a neutral pH and is stable in the presence of metal ions. This enzyme is structurally similar to subtilisin, with a sequence of residues containing two histidine residues, which are important for stability. The kinetic parameters of this enzyme were determined by analyzing its activity under different conditions and at different temperatures. The mutant Z-Phe-Leu-Ala-OH was found to be more active than the wild type at high temperature, but less active at low temperature, suggesting that the protein could be used as an industrial catalyst in food processing or chemical production.

Bosentan is a potent inhibitor of the uptake of organic anions. It is used in the treatment of pulmonary arterial hypertension and has been shown to be effective against pravastatin-resistant HIV protease inhibitors, such as saquinavir, quinidine, and rosuvastatin. Bosentan inhibits uptake by binding to the transporter protein at a site that does not overlap with the binding site for organic anion substrates. This leads to a change in kinetic parameters for substrates, such as pravastatin and saquinavir. The binding site on bosentan may also be elucidated through monolayer experiments with efflux transporters.

Endogenous heptapetide which causes vasodilation and has anti-hypertensive properties.

8-Phenyltheophylline (8PT) is an adenosine receptor agonist that is used as a bronchodilator for the treatment of asthma. It has been shown to increase the intracellular calcium concentration in hl-60 cells and in rat papillary muscles. 8PT also has locomotor activating effects, which are thought to be due to its ability to block potassium channels in the hippocampal formation. These effects may be related to ATP-sensitive potassium channels, which have been shown to be sensitive to ATP in untreated mice. 8PT also has anti-arrhythmic properties, which may be due to its ability to inhibit sodium channels and its effect on heart rate and contractility.
