(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-Oxo-3-hydroxy-N-methyl-N-propyl D-lysergamide (2OMD) is a metabolite of the drug lysergic acid diethylamide (LSD). It can be detected in urine, blood, and saliva.

This compound can also be found in some foods and beverages as a result of its presence as a natural component or from contamination during processing. !-- END-->

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

1-Phenylcyclohexanol (1-PC) is an organic compound that is used as a reagent in the synthesis of other compounds. It is a colorless liquid with a pleasant odor. 1-PC has been shown to have synergic effects when reacted with various types of oxidizing agents, such as magnesium and boron trichloride. The reaction products are cyclohexanol, dehydration, and modifiers. When 1-PC reacts with phenylcyclohexene, it forms the antigen hemiketal.

2-Methyl pentanoic acid is a coordination complex that is synthesized by the condensation of propionyl chloride and 2-methylpentanoyl chloride. It has been shown to have anticancer activity against human cervical cancer cells, inhibiting the growth of cells in culture. The mechanism of action may be due to its ability to inhibit the production of mitochondrial proteins, leading to cell death. 2-Methyl pentanoic acid also has a strong affinity for fatty acids and can be used as an inhibitor of fatty acid synthase, which is an enzyme that catalyzes the synthesis of long chain fatty acids in mitochondria. 2-Methyl pentanoic acid can also be used as a treatment for seizures caused by divalproex sodium and isovaleric acid. It inhibits the production of 3-hydroxyisovaleric acid, which is responsible for these seizures, through competitive inhibition with valine at the 3 position on the enzyme's active site.

N-Methyl-5H-dibenzo[a,d]cycloheptene-5-propylamine hydrochloride (NMBPD) is a drug with anti-inflammatory properties that belongs to the class of tricyclic antidepressants. It has been shown to have synergistic effects with synthetic matrix in vitro. This drug also has receptor activity and can be used to treat infectious diseases such as HIV and tuberculosis. NMBPD is excreted in the urine, which can lead to kidney fibrosis. The drug is metabolized by α1-acid glycoprotein, which may be related to its potential adverse effects on the liver and kidneys. The analytical method for quantification of NMBPD includes gas chromatography with mass spectrometry detection (GC/MS).

Z-NH-PEG8-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-PEG8-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.

2-Hydroxy-4-methylquinoline is an organic compound that has a chelate ring. It is soluble in deionized water and reacts with metal ions to form a fluorescent product.
