Formation of N-nitrosodimethylamine During the storage of Ranitidine reagent powders and tablets

By Danielle

Temperature-dependent formation of N-nitrosodimethylamine during the storage of ranitidine reagent powders and tablets

The purpose of this study was to elucidate the effect of high-temperature storage on the stability of ranitidine, specifically with respect to the potential formation of N-nitrosodimethylamine (NDMA), which is classified as a probable human carcinogen.
Commercially available ranitidine reagent powders and formulations were stored under various conditions, and subjected to LC-MS/MS analysis. When ranitidine tablets from two different brands (designated as tablet A and tablet B) were stored under accelerated condition (40°C with 75% relative humidity), following the drug stability guidelines issued by the International Conference on Harmonisation (ICH-Q1A), for up to 8 weeks, the amount of NDMA in them substantially increased from 0.19 to 116 ppm and from 2.89 to 18 ppm, respectively.
  • The formation of NDMA that exceeded the acceptable daily intake limit (0.32 ppm) at the temperature used under accelerated storage conditions clearly highlights the risk of NDMA formation in ranitidine formulations when extrapolated to storage under ambient conditions.
  • A forced-degradation study under the stress condition (60°C for 1 week) strongly suggested that environmental factors such as moisture and oxygen are involved in the formation of NDMA in ranitidine formulations.
  • Storage of ranitidine tablets and reagent powders at the high temperatures also increased the amount of nitrite, which is considered one of the factors influencing NDMA formation. These data indicate the necessity of controlling/monitoring stability-related factors, in addition to controlling impurities during the manufacturing process, in order to mitigate nitrosamine-related health risks of certain pharmaceuticals.

Bifunctional Reagents for Formylglycine Conjugation: Pitfalls and Breakthroughs

Formylglycine-generating enzymes specifically oxidize cysteine within the consensus sequence CxPxR to C α -formylglycine (FGly). This non-canonical electrophilic amino acid can subsequently be addressed selectively via bioorthogonal Hydrazino- iso -Pictet-Spengler (HIPS) or Knoevenagel ligation to attach payloads like fluorophores or drugs to proteins, while obtaining a defined payload-to-protein ratio. However, disadvantages of these conjugation techniques include the need of a large excess of conjugation building block, comparably low reaction rates and limited stability of FGly-containing proteins.
  • Therefore, functionalized clickable HIPS and tandem Knoevenagel building blocks were synthesized, conjugated to small proteins (DARPins) and subsequently linked to strained alkyne-containing payloads for protein labeling. This procedure allowed the selective bioconjugation of one or two DBCO-carrying payloads with nearly stoichiometric amounts at low concentrations.
  • Furthermore, an azide-modified tandem Knoevenagel building block enabled the synthesis of branched PEG-linkers and the conjugation of two fluorophores, resulting in an improved signal-to-noise ratio in live cell fluorescence imaging experiments targeting the EGF-receptor.

Buzz about RT-qPCR: An RT-qPCR formulation for SARS-CoV-2 detection using reagents produced at Georgia Institute of Technology

Widespread testing for the presence novel coronavirus SARS-CoV-2 in patients remains vital for controlling the COVID-19 pandemic prior to the advent of an effective treatment.
  • The early testing shortfall in some parts of the US can be traced to an initial shortage of supplies, expertise and/or instrumentation necessary to detect the virus by quantitative reverse transcription polymerase chain reaction (RT-qPCR). Here we show that academic biochemistry and molecular biology laboratories equipped with appropriate expertise and infrastructure can produce the RT-qPCR assay and backfill pipeline shortages.
  • The Georgia Tech COVID-19 Test Kit Support Group synthesized multiplexed primers and probes and formulated a master mix composed of enzymes and proteins produced in-house. We compare the performance of our in-house kit to a commercial product used for diagnostic testing and describe implementation of environmental testing to monitor surfaces across various campus laboratories for the presence of SARS-CoV-2.

Design and scalable synthesis of novel N-alkyl-hydroxylamine reagents for the direct, Fe-catalyzed installation of medicinally relevant amines

Secondary and tertiary alkylamines are privileged substance classes which are often found in pharmaceuticals and other biologically active small molecules. Herein, we report their direct synthesis from alkenes through an aminative difunctionalization reaction enabled by iron catalysis.

A family of ten novel hydroxylamine-derived aminating reagents were designed for the installation of several medicinally relevant amine groups, such as methylamine, morpholine and piperazine, through the aminochlorination of alkenes.

The methodology displays an excellent functional group tolerance, and a broad scope of alkenes was converted to the corresponding products, including several drug-like molecules. Besides aminochlorination, the installation of other functionalities through aminoazidation, aminohydroxylation and even intramolecular carboamination reactions, is demonstrated, further highlighting the broad potential of these new reagents for the discovery of novel amination reactions.
