7-Methyluric acid is a purine derivative that is excreted in the urine. This compound can be used to measure the metabolic rate of an individual. 7-Methyluric acid reacts with caffeine to produce methylxanthines and uric acid, which are then measured by chromatographic methods. In order to measure the metabolic rate, a known amount of caffeine is given orally to Sprague-Dawley rats for a period of time, followed by measurement of 7-methyluric acid in their urine samples. The results show that the metabolic rate increases linearly with time.

Acetyl-L-phenylalanine ethyl ester is a substrate analogue that competes with the natural substrate, L-phenylalanine, for binding sites on the enzyme. The acetyl group of acetyl-L-phenylalanine ethyl ester reacts with the amino acid residues of L-phenylalanine to form covalent linkages. This prevents the enzyme from catalyzing reactions involving L-phenylalanine and other substrates. Acetyl-L-phenylalanine ethyl ester binds to cytochalasin B and inhibits its ability to bind to actin filaments, thus inhibiting cell growth. The high salt concentration in this experiment allows for separation of the protein from other cellular components by sephadex g-100 chromatography. Kinetic studies have been done on human serum albumin, which is a protein that can bind acetyl-L-phenylalanine ethl ester with a

L-Tyrosine hydrochloride is a pharmaceutical preparation that has been used clinically in the treatment of infectious diseases, cancer, and autoimmune diseases. Tyrosine is an amino acid with a hydroxyl group on its side chain. Tyrosine can be synthesized from phenylalanine by hydroxylation of the phenolic group and decarboxylation of the carboxylic acid group. It is also a precursor to catecholamines and other important biological molecules. L-Tyrosine hydrochloride is used as an intermediate in the production of monoclonal antibodies for use in cancer research. In addition, it has been shown to be an effective inhibitor of virus replication when combined with ester hydrochloride, which prevents the release of progeny virus particles from infected cells.

Z-NH-PEG5-CH2CH2COOH is a PEG compound with two different functional groups (also known as heterobifunctional). Unlike homobifunctional PEG compounds (same functional group on both ends), this type of compounds are more versatile as have two different anchor points. Z-NH-PEG5-CH2CH2COOH is used as a linker and spacer to add a PEG moiety, via pegylation (a bioconjugation technique) to proteins, peptides, oligonucleotides, small molecules and nanoparticles.

H-Pro-AMC hydrobromide salt is an enzyme that belongs to the family of proteases. H-Pro-AMC hydrobromide salt has been shown to have carboxypeptidase activity, which cleaves peptides at the C terminus of a single amino acid. It has also been shown to interact with other enzymes and proteins, such as recombinant proteins and enzymes from the ubiquitin-proteasome system. This enzyme's ability to cleave peptides at the C terminus of a single amino acid makes it useful for protein sequencing. H-Pro-AMC hydrobromide salt has also been sequenced and found to share homology with other proteases, such as subtilisin E.

H-Phe-Leu-Glu-Glu-Leu-OH is a synthetic vitamin B6 derivative that has been shown to be effective in treating infectious diseases. It inhibits the synthesis of proteins by inhibiting the carboxylase enzyme, which is involved in the reaction mechanism of amino acid metabolism. This drug also has a redox potential that is higher than that of other drugs and can react with coumarin derivatives to form quinones, which can inhibit protein synthesis. H-Phe-Leu-Glu-Glu-Leu-OH has been shown to be more effective than vitamin B6 in preventing stachyose accumulation and increasing body mass index. The drug also has an epoxidase activity that can lead to an increased production of reactive oxygen species, which may have antioxidant properties. H-Phe-Leu-Glu-Glu-Leu OH also contains a signal peptide and decarboxylated form

Z-D-Lys(Boc)-OH is a synthetic peptidomimetic that has been shown to selectively kill cancer cells. Z-D-Lys(Boc)-OH binds to the lysine residue on the target cell surface, which is not present in normal cells. This binding inhibits serine protease activity and disrupts the synthesis of peptides, which are essential for cellular function. The electron microscopic images show that this compound causes an enhancement of biological function in human pathogenic chlamydia.

Proinsulin C-Peptide is a subunit of insulin. It is produced by proteolytic cleavage of proinsulin and has been used as a diagnostic agent for pancreatic beta cell function. Proinsulin C-Peptide encompasses the amino acids from 55 to 89 in the sequence of insulin. It can be used as a diagnostic agent for type 1 diabetes mellitus, which is characterized by an autoimmune destruction of beta cells, and other diseases such as multiple myeloma and non-Hodgkin's lymphoma that are associated with decreased levels of proinsulin C-Peptide.

1,2,3,4-Tetrahydro-4,6-dihydroxy-2-methyl-isoquinoline is a useful building block in the synthesis of various compounds such as pharmaceuticals and pesticides. It is an intermediate for the preparation of other valuable chemicals such as the antihistamine diphenhydramine, which is used to treat allergies. Tetrahydroisoquinoline can also be used as a reagent to synthesize other chemical compounds. This compound has been used in research as well as commercial applications. Tetrahydroisoquinoline is also a versatile scaffold that can be modified to produce different derivatives with different properties.

3-Fluoro-4-methylaniline is a synthesized compound that is used to produce anti-cancer agents. It is an amide and has anti-cancer properties. 3-Fluoro-4-methylaniline also binds to DNA and inhibits the synthesis of proteins in cancer cells. The binding constants for ligands are found to be high. 3-Fluoro-4-methylaniline can also bind with DNA through intercalation or hybridization, which prevents transcription of RNA from DNA, thereby inhibiting protein synthesis. This results in cell death by apoptosis.

1-Methylimidazole-2-sulfonyl chloride is a synthetic estrogen that is used for the treatment of estrogen deficiency in women. It has been shown to increase plasma estradiol levels and reduce plasma testosterone levels. This drug is not active at physiological levels, but was found to have biological relevance when administered at higher doses. 1-Methylimidazole-2-sulfonyl chloride has been found to be effective in the treatment of cancer in humans, with a specific effect on breast cancer cells.

D-(+)-2-Chlorophenylglycine is a synthetic, chiral aldehyde that serves as an industrial solvent. It is used to produce other organic compounds and has been shown to cause environmental pollution. D-(+)-2-Chlorophenylglycine is also used in the synthesis of thiourea and organocatalysts. This compound is synthesized from quinidine and enantiomeric (D or L) thionyl chloride, which are both manufactured on an industrial scale. The stereoselective process for D-(+)-2-chlorophenylglycine involves the use of a chiral catalyst.

L-glutamic acid is a nonessential amino acid that is used as a food additive. L-glutamic acid is found in the form of sodium salt, called monosodium glutamate (MSG), and is used to enhance the flavor of foods. L-glutamic acid has been shown to be essential for the growth of certain bacteria, such as corynebacteria. The l-glutamic acid gene can be found in corynebacteria and corynebacterium glutamicum. It has been shown that l-glutamic acid can be synthesized by these organisms under conditions of low magnesium concentration, high pH, and high temperature.
