Mass spectrometry based fragmentation patterns of nitrosamine compounds

Abstract: Rationale Nitrosamines are a class of mutagenic substances that can display high carcinogenic potential. New chemical entities may have the potential to form unique nitrosamines specific to the drug substance. It is therefore essential to understand the gas‐phase fragmentation behavior of nitrosamine compounds to enable the development of analytical methods to characterize novel nitrosamine compounds. Methods The gas‐phase fragmentation behavior of eight model nitrosamine compounds representing the common subs… Show more

“…The current N -nitrosamine risk assessment approach in the pharmaceutical industry consists of paper-based evaluation of synthetic routes and subsequent GC-MS and/or LC-MS analysis of drug substances and drug products considered to be under risk for N -nitrosamine contamination. The current instrumental analytical methods that can quantify N -nitrosamines in levels below ppm region are time-consuming and expensive, require highly skilled personnel, and require development of the specific analytical method for each individual N -nitrosamine and each drug product.…”

“…This database comprises a total of 27,944 nitrosamines collected from various sources: safety assessments of pharmaceutical regulatory agencies, commercial suppliers, and in-silico-generated structures. Fragmentation rules were coded from the literature and in-house sources and the whole database was fragmented accordingly (more details on the two databases are provided in the Supporting Information).…”

“…In addition, analytical techniques such as HPLC, LC-MS/MS, HR-MS/MS, and GC-MS/MS should be developed for the testing and analysis in detecting and avoiding NMI in herbal products. All herbal products should be tested for the presence of NMI before they are released to the market, and regular testing should be conducted to ensure that NMI does not form over time during the storage of the herbal products [71][72][73][74][75] (▶Fig. 1).…”
