Glutaric acid is a dinucleotide phosphate that exists in two forms: the alpha form, which has a high phase transition temperature and is insoluble in water; and the beta form, which has a low phase transition temperature and is soluble in water. Glutaric acid can be used as an analytical reagent to identify the type of nucleotides present in samples. It can also be used as an experimental solvent for other compounds that are not soluble in water. The toxicity of glutaric acid has been studied extensively and found to be low. This compound does not appear to have any adverse effects on human health or animals at doses up to 1g/kg body weight. Glutaric acid has been shown to have anti-infectious properties by inhibiting the growth of bacteria, fungi, and viruses. The effectiveness of glutaric acid against infectious diseases appears to depend on its ability to block protein synthesis by inhibiting enzymes such as glutathione reductase

4-Nitrophenylacetone is a hypoglycemic agent that is used for the treatment of diabetes mellitus. It has been shown to be effective in vivo and in vitro studies at low concentrations. The mechanism of action is not well understood, but it may have effects on insulin sensitivity and the release of insulin from pancreatic beta cells, as well as an effect on the liver. 4-Nitrophenylacetone has been shown to have organocatalytic properties that allow it to catalyze acylation reactions with acetanilides or amides. This reaction produces iminium ion intermediates that can be hydrolyzed by water to form a variety of products, including carboxylic acids, amides, and nitriles.

DL-Threonine (or 2-amino-3-hydroxybutanoic acid), is an essential, non-protein amino acid naturally occurring in the human body and it is involved in many biological processes. DL-threonine takes part in the conversion of glycogen into the glucose pathway, supports muscle tissue maintenance and growth, and plays a key role in regulating levels of other amino acids. In addition, DL-threonine helps to provide protection against heat, reduce tiredness and lowers blood pressure. It is an important source of energy for the liver and has been shown to be effective in stimulating liver function, as well as, to have a protective effect against various diseases, including hepatitis and cirrhosis. The liver uses DL-Threonine to produce other amino acids and helping in protein synthesis, such as insulin. The human body can produce DL-threonine from serine by threonine synthase, but not enough to meet the body's needs and thus it must be obtained from food sources or supplements. DL-Threonine can be found in many foods including meat, eggs, soybeans, and dairy products. It can chelate metal cations to improve the absorption of minerals from supplements, which is used in fertilizers for agriculture.

3,4-Dimethylcinnamic acid is a plant-derived compound that has been shown to have anti-inflammatory properties. It inhibits the production of prostaglandins by inhibiting cyclooxygenase activity and reducing the production of pro-inflammatory eicosanoids. 3,4-Dimethylcinnamic acid also blocks the synthesis of leukotrienes and thromboxanes, which are involved in inflammation as well as allergic reactions and asthma. 3,4-Dimethylcinnamic acid is used to treat skin conditions such as psoriasis, eczema, or dermatitis. This compound can be obtained from plants like Dracaena fragrans (also known as Madagascar dragon tree) or ethnomedicine sources such as the African shrub Anthranilic acid. 3,4-Dimethylcinnamic acid can be synthesized by cross coupling with alkyl halides, ultraviolet irradiation of anthranils with uv

Bromocresol green is a dye that is used in biological assays to measure the kinetics of fluorescence. It is a type of tryptophan-releasing compound that releases a yellowish-green light when it absorbs light at wavelengths between 350 and 450 nm. Bromocresol green has been quantified by measuring the intensity of the fluorescence emission as a function of time. This can be done visually or using an instrument called a fluorometer, which detects changes in light intensity over time. Bromocresol green can be used to detect the presence of amino acid residues in proteins through protonation reactions with their tryptophan residues and subsequent quenching with acetonitrile. The bromocresol green dye is also used in lithographic printing, where it serves as an acceptor for electrons from an arene (aromatic hydrocarbon). This process generates energy for lithography and also provides contrast between regions with different electron densities.

4'-(Trifluoromethyl)acetophenone is a phosphatase inhibitor that has been shown to have inhibitory activity against chemokines.

Kinetic studies have demonstrated that this reaction is reversible in solution at room temperature.

1-(4-Nitrophenyl)glycerol has been shown to inhibit the growth of Gram-positive bacteria, including Streptococcus faecalis, and Gram-negative bacteria, including Pseudomonas aeruginosa. It is also used as a sample preparation for antimicrobial resistance testing.

(3-Hydroxyphenyl)acetic acid methyl ester is an allosteric inhibitor of the serotonin transporter (SERT), which is a target enzyme for many drugs. It has inhibitory activity against 5-HT1A receptors, and other targets that have not yet been elucidated. This compound has been shown to react with coumarin derivatives to form reaction products. The molecular modelling of this drug shows that its uptake is inhibited by the presence of acids, such as hydrochloric acid, in the environment. The rate of reaction between (3-hydroxyphenyl)acetic acid methyl ester and serotonin has been determined experimentally using kinetic data. Molecular modeling predicts that this compound will bind tightly to the SERT protein via hydrogen bonding interactions with amino acids in the binding site.

Acetyl-L-tyrosine amide is an analog of L-tyrosine that is used as an active substance in the field of uv absorption. Acetyl-L-tyrosine amide reacts with sodium hydroxide to form a soluble salt, which has been shown to have binding constants that are comparable to those of human serum. This compound also has fluorescence properties and can be used for the determination of neutral pH. The reaction products formed between acetyl-L-tyrosine amide and sodium hydroxide are hydrolyzed by acids and yield a molecule with rotameric properties. These rotameric properties can be modeled using a protein model without affecting the stability or function of the protein.

5-Methyl-2-nitrophenol is a phytotoxic chemical that is used as a synthetic intermediate in organic chemistry. It has been shown to have a high bioconcentration factor and can be found in wastewater.

It also has pharmacological properties, which may be due to its derivates that are isolated from these plants. HTMC shows no adverse effects on humans when taken orally at doses up to 1 g/day for 28 days.
