LC-ESI-MS/MS reveals the formation of reactive intermediates in brigatinib metabolism: elucidation of bioactivation pathways

Brigatinib (BGB) is a newly approved anaplastic lymphoma kinase (ALK) inhibitor. On April 28, 2017, BGB was approved by the U.S. FDA for the treatment of metastatic anaplastic lymphoma kinase-positive non-small cell lung cancer. The toxicity profile of BGB includes nausea, fatigue, diarrhea, elevated lipase, dyspnoea, hypertension, hypoxia, pneumonia, elevated amylase, pulmonary embolism, elevated ALT, hyponatraemia and hypophosphatemia. Using LC-MS/MS, we investigated the in vitro phase I metabolism of for BGB in rat liver microsomes (RLMs). In the in vitro metabolism of BGB, iminium reactive intermediates were trapped by potassium cyanide forming a stable complex that can be characterized by LC-MS/MS. Four BGB in vitro phase I metabolites were identified. In vitro phase I metabolic pathways were N-dealkylation, alpha hydroxylation and alpha oxidation. Additionally, three iminium reactive metabolites were found and the bioactivation mechanisms were proposed. A piperidine ring was found to be responsible for BGB bioactivation. The presence of these three reactive metabolites may be the main reason for BGB side effects. A literature review showed no previous article reported the in vitro phase I metabolism study of BGB or structural identification of the formed reactive metabolites.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 201341-05-1, you can contact me at any time and look forward to more communication. Product Details of 201341-05-1.

Deconstructive fluorination of cyclic amines by carbon-carbon cleavage

Deconstructive functionalizations involving scission of carbon-carbon double bonds are well established. In contrast, unstrained C(sp(3))-C(sp(3)) bond cleavage and functionalization have less precedent. Here we report the use of deconstructive fluorination to access mono-and difluorinated amine derivatives by C(sp(3))-C(sp(3)) bond cleavage in saturated nitrogen heterocycles such as piperidines and pyrrolidines. Silver-mediated ring-opening fluorination using Selectfluor highlights a strategy for cyclic amine functionalization and late-stage skeletal diversification, establishing cyclic amines as synthons for amino alkyl radicals and providing synthetic routes to valuable building blocks.

Metabolomics analysis of nitrogen-containing metabolites between two Dendrobium plants

Nitrogen-containing compounds especially alkaloids are important medicinal ingredients in caulis dendrobii plants. Using solid-phase extraction coupled with liquid chromatography tandem mass spectrometry and multivariate data analysis methods, metabolic profiling of the nitrogen-containing compounds was established to distinguish Dendrobium huoshanense and Dendrobium officinale. Hundreds of nitrogen-containing compounds from the two caulis dendrobii were purified by the MCX cartridges. Some compounds were identified by high-resolution tandem mass spectrometry technology. Together with multivariate data analysis methods, comparative analysis of the metabolic profiling from two caulis dendrobii was conducted. A total of 133 nitrogen-containing compounds were identified, including amino acids, pyrrolidines, tropanes, pyrimidines, purines, indoles, piperidines, guanidines, quinolines, isoquinolines and terpenoids. Metabolic profiling analysis showed that the composition and contents of these chemical components were significantly different between D. huoshanense and D. officinale. Moreover, some components were species-specific, distributed in the two caulis dendrobii, such as pilosine, ternatusine, etc. Because alkaloids are mainly derived from amino acids via multistep biochemical reactions, the correlation analysis suggested that amino acids were partially associated with several types of components and significantly correlated with certain alkaloids. Arginine was extremely correlated with guanidines. Pyrimidines, purines and niacin-nicotinamide metabolic intermediates were associated with three independent networks. The results further enriched the chemical components currently identified from caulis dendrobii and provided a technical reference for detecting nitrogen-containing compounds in other medicinal plants.

Catalytic Asymmetric Construction of Halogenated Stereogenic Carbon Centers by Direct Vinylogous Mannich-Type Reaction

A catalytic asymmetric vinylogous Mannich-type reaction of gamma-halo-alpha,beta-unsaturated N-acylpyrazoles and N-Boc-aldimines was disclosed, which afforded an array of halogenated (F-, Cl-, and Br-) allylic stereogenic carbon centers in high yields with good to high regio-, diastereo-, and enantioselectivities. The brominated product served as a suitable electrophile for common S(N)2 nucleophilic substitution and copper mediated S(N)2′ allylic alkylation with metal reagents. The utility of present methodology was demonstrated by the asymmetric synthesis of a common intermediate toward the synthesis of two chiral 2,3-disubstituted piperidine pharmaceuticals.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 201341-05-1. SDS of cas: 201341-05-1.

Synthesis and Evaluation of a New Acryloyl-Based Copolymer as Kinetic Hydrate Inhibitor for Sour Gas Environments

Blockage of gas flow lines by gas hydrates is a major problem in the oil and gas industry, which leads to severe safety issues and causes economic losses. Kinetic hydrate inhibitors (KHIs) are water-soluble polymers that are employed to circumvent this problem due to their effectiveness at low dosage, which makes logistics (transport, storage, and pumping) less costly particularly in offshore operations. However, some of the currently available KHI polymers have subcooling constraints against class I hydrates in high sour gas conditions, which limit their utilization. In this Article, we report a new KHI copolymer synthesized from N-acryloyl pyrrolidine and N-acryloyl piperidine monomers. Detailed characterization and compatibility studies were carried out using a variety of techniques and tests. The rocking cell test demonstrated the new formulation’s effectiveness to a high subcooling temperature of 8.5 degrees C at 140 bar of a gas mixture containing a high concentration of CO2 and H2S. The performance of the copolymer was investigated at 2% and 3% dosage, where the increased dosage of copolymer showed a higher subcooling temperature. Collectively, these results set a stage for the design, development, and evaluation of a new type of polymers as an effective KHI.

Newly designed pyridine and piperidine based Ionic Liquids: Aggregation behavior in ESI-MS and catalytic activity in C – C bond formation reactions

Material preparation using Ionic Liquids (ILs) as a catalyst was frequently related to the supramolecular aggregation behavior. Hence, understanding the aggregation behavior of ILs is very significant from basic and applied aspects. The present work suggested an efficient and green protocol for the synthesis of pyridine and piperidine based ILs with different phenoxide as anions. Furthermore, the supramolecular polymeric aggregation due to non-covalent interactions between cations and anions of these ILs were investigated through Electrospray Ionization Mass Spectrometry (ESI-MS). Moreover, assessment of the suitability of these ILs as catalyst has been done in the presence of potassium carbonate for base-catalysed-carbon carbon bond formation reactions i.e. case of Knoevenagel and Claisen-Schmidt Condensation. The obtained products were characterized by spectroscopic methods such as H-1 NMR,C-13 NMR, ESI-MS and UV. The results revealed that the desire products were obtained in excellent yield (up to 98%). Selective ILs which contain electron with drawing group in anions such as m-nitro phenoxide ion, exhibited remarkable catalytic activity in Condensation reaction. In addition to this, ESI-MS of ILs showed that peak distributions prominently exhibited for each aggregate, a decrease in ion abundance occurred. (C) 2018 Elsevier B.V. All rights reserved.
