APIs for research and impurities

11-(1-Piperazinyl)dibenzo[b,f][1,4]thiazepine hydrochloride is a drug product that is used as an impurity standard in the manufacture of 11-aminoundecanoic acid. It is also used to study the metabolism of this compound. This drug product is not intended for use in humans or animals.

4-(Diethylboranyl)pyridine is a nucleophilic, anticoagulant drug. It interacts with the electronegative oxygen atoms in the guanine base of dna to form an adduct, which inhibits DNA synthesis. The hexameric cavity of 4-(Diethylboranyl)pyridine contains boron and nitrogen atoms, which are important for its activity. 4-(Diethylboranyl)pyridine also has antibacterial effects against gram-positive bacteria by inhibiting bacterial protein synthesis. This compound is synthetic and can be used in cocrystallized form as a single molecule or in hexameric form.

6-Bromo-1-hydroxypyrene is a natural metabolite of the aromatic hydrocarbon benzo[a]pyrene. It has been used as an analytical standard for HPLC and GC analyses, and as a research and development (R&D) drug product in pharmacopoeia. 6-Bromo-1-hydroxypyrene has been shown to have anti-inflammatory activities in mouse skin. It also inhibits liver microsomal cytochrome P450 enzymes, suggesting that it may be useful in the treatment of disorders such as Alzheimer's disease.

Applications Antihypertensive.

Applications An β2-adrenergic agonist. Bronchodilator; tocolytic. References Schuster, B., et al. Arzneim.-Forsch., 19, 1905 (1969), Gerris, J., et al.: Eur. J. Clin. Pharmacol., 18, 443 (1980), Heel, R.C., et al.: Drugs, 15, 3 (1978),

Tilnoprofen arbamel is a synthetic drug with antipyretic and analgesic properties, which is made in the laboratory. It is a metabolite of tilnoprofen that has been synthesized to meet the pharmacopoeia standards for purity. Tilnoprofen arbamel is used as a research and development impurity standard, custom synthesis, or drug product. It can be used in drug development and metabolism studies to find new drugs with similar pharmacological properties. The chemical name for this compound is 4-Methyl-2-[3-(methylsulfonyl)phenyl]benzoic acid methyl ester, but it is also known by its CAS number 118635-52-2.
