6-Benzoyl-2,3-dihydro-1H-pyrrolizine-1-carboxylic acid, racemic is a drug product that is used as an analytical standard in the development of new drugs. It is also used to study the metabolism of drugs. 6BPDC has been shown to inhibit bacterial growth by binding to DNA and RNA, thereby preventing transcription and replication. This metabolite can be synthesized in the laboratory.

Applications Clothiapine-d8, is the labeled analogue of Clothiapine (C588550), a atypical antipsychotic of the dibenzothiazepine chemical class. It has shown efficacy in treatment-resistant schizophrenic patients. Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package References Schmutz, J., et al.: Helvetica Chimica Acta 50, 245 (1967); Geller, V., et al.: Schizophrenia Research 80 (2-3), 343 (2005);

Applications Labelled abalogue of Maleic Hydrazide, a compound used in plant growth regulator formulations. References Calliera, M. et al.: Pest Manag. Sci., 62, 1168 (2006); Berrada, H., et al.: Food Control. 21, 36 (2010); Nougadere, A. et al.: Food Chem. Toxicol., 49, 1484 (2011);

Applications Roscovitine is a potent and selective inhibitor of cyclin-dependent kinases (CDKs). Roscovitine has been found to produce apoptosis in treated cancerous cells of non-small cell lung cancer (NSCLC) and other cancers. Studies show that Roscovitine displays increased anti-mitotic activity at the G1/S and G2/M phases of the cell cycle. Roscovitine maybe useful in the treatment of non-small cell lung cancer (NSCLC), leukemia, HIV infection, herpes simplex infection, and the mechanisms of chronic inflammation disorders.

Applications Nebivolol Hydrochloride is a highly selective β1-adrenoceptor antagonist. References Van de Water, A., et al.: J. Cardiovasc. Pharmacol., 11, 552 (1988), De Cree, J., et al.: Angiology, 41, 95 (1990);

10-Oxo mirtazapine is a metabolite of the antidepressant drug mirtazapine. It is an impurity in the HPLC standard for mirtazapine and has been shown to be pharmacologically active in animal models. 10-Oxo mirtazapine has also been found to be an impurity in other drugs, such as fluoxetine hydrochloride, but it is not known if it has any activity.

Applications Dopamine D2-receptor antagonist. An antipsychotic. References Lavelle, C., et al.: J. Pharmacol., 5, 58 (1974), Morel, D., et al.: Sem. Hop., 59, 2337 (1983), Kamizono, A., et al.: Biol. Pharm. Bull., 16, 1121 (1993),

Tirofiban impurity 8 is an analytical standard for HPLC. It is a research-grade, high purity, impurity standard for the drug product. Tirofiban impurity 8 is a metabolite of tirofiban that has been shown to be pharmacologically active in animal models and in vitro. Tirofiban impurity 8 has a natural or synthetic origin and its CAS number is 2250244-25-6.

Applications Butyrophenone derivative having neuroleptic activity, used as an antipsychotic.
