General description

4-Nitrobenzoyl chloride reacts with triphenylphosphonium salt to synthesize benzofurans (potential positron emission tomography (PET) tracers) by the intramolecular Wittig reaction.It has been used for the derivatisation of Adiol (Androstenediol, an endogenous proliferation agent of prostate cancer).

Application

<ul>
<li><strong>Automated Synthesis of [11C]PiB:</strong> 4-Nitrobenzoyl chloride is utilized in the automated synthesis of [11C]PiB, a radiopharmaceutical for PET imaging of amyloid, highlighting its role in enhancing neuroimaging techniques (Singh et al., 2024).</li>

A novel series of benzofuran derivatives as potential positron emission tomography (PET) tracers targeting amyloid plaques in Alzheimer's disease (AD) were synthesized and evaluated. The syntheses of benzofurans were successfully achieved by an intramolecular Wittig reaction between triphenylphosphonium salt and

The dynamics of enzyme-catalyzed glutathione conjugation was studied by electrospray quadrupole/time-of-flight (Q-TOF) mass spectrometry with a nanospray interface. After incubation of human glutathione S-transferase A1-1 (GT) with glutathione (GSH) and an electrophilic substrate, electrospray indicated the presence of enzyme/product adducts

Conjugation of xenobiotics with glutathione occurs commonly within the liver, and these glutathione conjugates are then preferentially excreted into bile. We have characterized this excretory process using primary cultured hepatocytes (24 h). 1-Chloro-2,4-dinitrobenzene rapidly entered the cells and formed a
