(S)-3',5'-Bis(trifluoromethyl)-1-phenethanol is a choline derivative that is used in the treatment of liver cancer. It has been shown to increase the permeability of cell membranes and to suppress the growth of tumor cells by inhibiting protein synthesis. (S)-3',5'-Bis(trifluoromethyl)-1-phenethanol can be used as a surfactant and a hydrophobic solvent for optimization of reaction parameters. This chemical also has been shown to be active against Gram-positive bacteria such as Staphylococcus aureus and Enterococcus faecalis, but not against Gram-negative bacteria such as Escherichia coli or Pseudomonas aeruginosa. The mechanism of this effect is mediated by chloride ions that act as bioreductive agents on cellular membranes, leading to increased permeability and cell death.

2,4,4’-Trichlorobiphenyl is a polychlorinated biphenyl congener. It has been shown to have an adverse effect on the central nervous system, causing neurotoxicity. 2,4,4’-Trichlorobiphenyl has been used as a model system for the study of the effects of environmental toxins on mitochondrial membrane potential and lipid peroxidation. 2,4,4’-Trichlorobiphenyl binds to fatty acids in mitochondria and inhibits fatty acid β-oxidation. The inhibition of fatty acid oxidation leads to increased levels of protocatechuic acid in the serum and liver tissue. 2,4,4’-Trichlorobiphenyl has also been found to be toxic to aquatic organisms such as fish and shrimp at low concentrations.

All-trans-retinol is a form of vitamin A that is found in many animal tissues and some plant oils. It acts as a hormone, binding to the retinoic acid receptors (RARs) in the nucleus and activating gene transcription. All-trans-retinol has been shown to be effective against hyperproliferative diseases such as cancer, both by inducing apoptosis and by inhibiting cell growth. All-trans-retinol may also have therapeutic potential for other diseases, such as intestinal cancers and prostatic hypertrophy. This compound has been shown to induce messenger RNA (mRNA) production in cells that express RARs.

a,O-Dimethyl serotonin is a monoamine compound that is synthesized by the enzymatic decarboxylation of 5-hydroxytryptophan. It has been shown to increase dopamine levels and inhibit the enzyme activity of serotonin in mice. This drug also binds to 5-ht2 receptors and induces the release of serotonin from nerve cells. A linear calibration curve was obtained using bufotenin as a standard. This drug has been used in analytical toxicology for determining the uptake of serotonin into human lung tissue and its effect on 5-ht1a receptors. In addition, a study was conducted with perennial ryegrass to determine whether this drug inhibits plant toxin synthesis. The results showed that it did not have an inhibitory effect on plant toxins and may even promote their synthesis.

4-Nitrophenyl anthranilate is a potent inhibitor of serine protease. It is synthesized by reacting an anthranilate with an hydroxyl group in the presence of ultraviolet light, and can be used as a fluorescent probe. 4-Nitrophenyl anthranilate binds to the active site of serine protease, and prevents the hydrolysis of proteins by blocking the cleavage of peptide bonds at the carboxylic acid termini. This compound has been shown to inhibit human serum albumin and cell nuclei in vitro. The reaction mechanism for this compound is unknown, but it is believed that it may involve a photo-induced electron transfer mechanism.

Codeine Impurity F is a biochemical that is an impurity of codeine. Codeine Impurity F is a byproduct of the enzymatic reaction with morphine and the bacterial strain Pseudomonas putida. Codeine Impurity F has been shown to inhibit the growth of gram-negative bacteria, including Escherichia coli and Salmonella enterica, by binding to cellular membranes and inhibiting their function. It also binds to RNA in vitro and prevents translation of mRNA from its ribosome complex. The hydroxyl group on Codeine Impurity F binds to aluminium ions, which may interfere with the absorption of other drugs such as ampicillin or tetracycline. This impurity has been shown to have an effect on biological products such as immunoglobulins and albumin.

1-(Aminomethyl)naphthalene is a hydrogen bond-forming molecule that has high values of hydrochloric acid. This compound reacts with sodium carbonate to form glycoside derivatives, which have been shown to display light emission. 1-(Aminomethyl)naphthalene can be used in the synthesis of oxytocin and toll-like receptor ligands, as well as other chemical reactions. The carbonyl group found in this molecule is responsible for the reactivity and stability of this compound.

Bromocresol purple sodium salt is a dye that emits light when it is irradiated with light of a particular wavelength. It has been used to detect amniotic fluid contamination in the laboratory and as an absorber in polymer films. Bromocresol purple sodium salt absorbs ultraviolet and visible light, which causes it to emit red light. The molecules of bromocresol purple sodium salt are long-chain triazoles, which absorb water vapor and emit infrared radiation. This property can be used to detect the presence of alkali metals. The luminescent property of bromocresol purple sodium salt can be enhanced by adding an alkali metal, such as potassium or lithium chloride, to the solution where it is dissolved.
