1,2,3,4-Butanetetracarboxylic acid is a chemical compound that has been synthesized from e. coli and laboratory preparation methods. It is an active agent against bacteria that can be prepared by hydrochloric acid and has shown a high yield for the production of this compound. 1,2,3,4-Butanetetracarboxylic acid has antibacterial activity and is also effective against fungi such as Trichophyton mentagrophytes. It inhibits the growth of bacteria by binding to their cell wall and preventing them from using their cell wall for synthesis. This compound also has antifungal activity due to its inhibition of fungal cell wall synthesis. 1,2,3,4-Butanetetracarboxylic acid crystallizes in a monoclinic crystal system with space group C2/c. The unit cell dimensions are: a = 9.632 Å;

Applications A metabolite of the PAH micropollutant Fluorene (F462002) with potential mutagenic effects. It is used as biomarkers to evaluate exposure to PAHs and environmental tobacco smoke in general population. References Gmeiner, G. et al.: J. Chrom. B Anal. Technol. Biomed.

Octyl isocyanate is a non-steroidal anti-inflammatory drug that belongs to the class of isocyanates. The biological activity of octyl isocyanate has been studied extensively, and it has been shown to inhibit the polymerase chain reaction (PCR). Octyl isocyanate also inhibits the growth of bacteria in vitro through metal chelation and polymyxin B., which are antibiotics that bind metal ions and disrupt bacterial cell membranes. Octyl isocyanate has been shown to be reactive in vivo, leading to autophagy and necrosis.

1,4-Bis-(diphenylphosphino)butane is a coordination compound that contains a bicyclic heterocycle. The compounds are made up of phosphorus and nitrogen atoms which are arranged in a tetrahedral geometry. It has photochemical properties and can be used to inhibit the growth of myeloid leukemia cells. The complexes bind to amines and form stable complexes with hydroxyl groups, so they are also able to cross mitochondrial membranes. This compound has been shown to bind to copper ions in x-ray crystal structures. 1,4-Bis-(diphenylphosphino)butane binds more strongly to ethylene diamine than it does to aryl halides such as chloroethane or phenylethane. Activation energies for the binding of 1,4-bis-(diphenylphosphino)butane with ethylene diamine have been found by measuring the free energy change for its formation from

Diazepam (also known as Valium) is a benzodiazepine drug used to treat anxiety disorders, muscle spasms, alcohol withdrawal symptoms, and other conditions. Diazepam is a tranquilizer that works by slowing down the activity of the central nervous system. It may also be used to control seizures, prevent certain types of muscle spasms, treat insomnia and relieve anxiety before surgery. Diazepam has been shown to have an affinity for nicotinic acetylcholine receptors in rat brains. This drug can work by blocking these receptors and preventing the transmission of impulses between neurons. Diazepam is marketed in many countries as an anxiolytic agent under trade names such as Valium and Librium. The clinical use of diazepam should be limited because it has been shown to cause birth defects in animal studies when given at high doses or during pregnancy.

4-Phenyl-2-butanol is a monoclonal antibody that is used in the treatment of human immunodeficiency virus (HIV). It is an aromatic hydrocarbon that binds to amines and reacts with malonic acid, which has monophenolase activity. The resulting product, dimethyl malonate, reacts with unsaturated ketones to form diphenols. The reaction solution also contains chloride yields, which are generated by the conversion of amines to their corresponding chlorides. 4-Phenyl-2-butanol has been shown to have enantiopure properties for the synthesis of fatty acids and other compounds containing unsaturated ketones.
