General description
Desalkylflurazepam, also known as N-desalkyl-2-oxoquazepam, is a long-acting metabolite of the benzodiazepine drug flurazepam. Flurazepam is sold unde the trade names Dalmane and Dalmadorm for the treatment of mild to moderate insomnia. This Certified Spiking Solution® is suited for use in LC/MS or GC/MS applications for clinical toxicology, forensic analysis or urine drug testing.
Application
- Pharmacokinetic profiling: Research on flurazepam metabolites, including Desalkylflurazepam, utilizes high-performance liquid chromatography for detailed pharmacokinetic studies in rats, providing essential data for understanding drug behavior and metabolism (Lau et al., 1987).
- Neuroscience tool: Desalkylflurazepam is applied in neuroscience research to understand the dynamics of benzodiazepine binding on living cells, utilizing small ligands in fluorescence correlation spectroscopy, a method pivotal for real-time molecular interactions study (Hegener et al., 2002).
- Drug testing applications: The compound is used in the development of analytical techniques like ultra-high-performance liquid chromatography-mass spectrometry (UHPLC-MS/MS) for the detection of benzodiazepines in hair, useful in workplace drug testing and forensic science (Ramírez Fernández et al., 2015).
- Toxicological analysis: Desalkylflurazepam serves as a reference standard in forensic toxicology to facilitate the rapid determination of benzodiazepines and their metabolites in biological samples, crucial for accurate and swift diagnostic purposes (Jeong et al., 2015).
- Immunosorbent assay applications: This benzodiazepine metabolite is instrumental in examining cross-reactivity of psychoactive substances in enzyme-linked immunosorbent assay (ELISA) techniques, enhancing drug testing capabilities in clinical settings (Cieri et al., 2024).

The potency of several new benzodiazepines as inhibitors of [3H]flunitrazepam binding was investigated in membranes from rat cerebellum or hippocampus. It was found that quazepam and two of its metabolites have a higher affinity for benzodiazepine receptors in cerebellum than

The absorption, metabolism, and excretion of quazepam, a new benzodiazepine hypnotic, was investigated in six normal male volunteers after oral administration of 25 mg 14C-quazepam in solution. Quazepam was well absorbed. Plasma radioactivity peaked (324.6 ng quazepam eq/ml) 1.75 hr

Previous metabolic studies have established that two major metabolites, 2-oxoquazepam and N-desalkyl-2-oxoquazepam, are present in plasma after dosing with quazepam, a new benzodiazepine hypnotic. The excretion of quazepam, 2-oxoquazepam, and N-desalkyl-2-oxoquazepam into human breast milk was studied in four lactating

Pharmacodynamic effects of ethyl 7-chloro-2,3-dihydro-5-(2-fluorophenyl)-2-oxo-1H-1,4- benzodiazepine-3-carboxylate (CM6912), a new benzodiazepine derivative, and its main metabolites (CM6913 = M1, CM7116 = M2) on the peripheral systems were investigated in several species of animals. In pentobarbital-anesthetized rabbits, CM6912 and M2 (1 or
