Synthesis of Cysteine–Fluorophore Conjugates by Visible‐Light‐Promoted Thiol–Ene Coupling Using Organic Photocatalysts

European Journal of Organic Chemistry, EarlyView.
Cysteine–fluorophore conjugates were efficiently prepared through a visible‐light‐driven thiol–ene approach employing solely organic photocatalysts. The reaction proceeds under mild, metal‐free conditions. The fluorophore scope includes mono‐ and dialkene‐functionalized naphthalene, naphthalimide, and aromatic diimide derivatives.

The Preparation of Novel Fluorenes Inspired by Hipposudoric Acid

Helvetica Chimica Acta, EarlyView.
In this research we report on the design and synthesis of a series of fluorene‐based derivatives loosely inspired by the tricyclic framework of hipposudoric acid. Preparation of sixteen novel N‐alkylated derivatives was accomplished via a series of concise one‐step amide N‐alkylation reactions.

New Hydrazone Derivatives Featuring Isatin and Piperazine Moieties: Synthesis, Cytotoxicity Evaluation, and Molecular Modeling Studies

Journal of Applied Toxicology, EarlyView.
ABSTRACT In this study, ten novel compounds (IPH1–IPH10) were designed by integrating three pharmacophores (isatin, piperazine, and hydrazone) commonly found in the molecular structures of anticancer agents. The target molecules were obtained by the reaction of in‐house prepared 4‐(4‐(pyridin/pyrimidin‐2‐yl)piperazin‐1‐yl)benzohydrazide with various ...

Mycotoxin management in the cereal supply chain: Advanced detection, detoxification, and smart packaging strategies

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Mycotoxins remain a persistent threat to the safety and quality of cereal grains and other agricultural products, and their impact on human health continues to raise global concerns. In many situations, the practices traditionally used to control these toxins are no longer sufficiently effective. They can be costly, difficult to implement on a

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).
