Investigations Into the Human Metabolism of Trestolone (7α‐Methyl‐19‐Nortestosterone)

Drug Testing and Analysis, EarlyView.
As the known metabolites of 7α‐methyl‐19‐nortestosterone (MENT), M1 and M2, suffer from chromatographic issues under routine doping control conditions, the human metabolism of MENT was reinvestigated. From the numerous new metabolites detected, especially, M5 and M10 were identified as the most promising candidates to be implemented into routine ...

Occurrence and Human Health Implications of Legacy Organochlorine Pesticides and Their Metabolites in Fruits and Vegetables of Bangladesh

Food Safety and Health, EarlyView.
Multiple OCP isomers and/or metabolites along with their parent compounds were detected in commonly consumed fruits and vegetables of Bangladesh, possibly attributed to both recently and historically applied OCPs. However, all the detected values were below 0.01 mg/kg, indicating no potential human health risks through dietary intake. ABSTRACT Globally,

Colorimetric and Fluorimetric Multiple Metal Ion Sensing Using Naphthalene‐Based Schiff Base

Helvetica Chimica Acta, EarlyView.
A naphthalene‐based Schiff base can detect different metal ions by fluorimetry and colorimetry. The coordination compounds of different metal ions are studied by single‐crystal X‐ray diffraction and their properties investigated in solution. ABSTRACT A novel Schiff base ligand functionalized with a naphthalene moiety has been developed as colorimetric ...

Achieving superior therapeutic effects on methicillin‐resistant Staphylococcus aureus infection via simple sulfonation process for preparing zwitterionic photosensitizer

Interdisciplinary Medicine, EarlyView.
The sulfonated zwitterionic photosensitizer (PYSO3) is synthesized by reacting maleic anhydride derivatives with 4‐aminopyridine to form PY, followed by sulfonation with 1,4‐butane sultone. It exhibits both photothermal and photodynamic properties, enabling effective eradication of MRSA and biofilms, as well as promoting wound healing in mice ...

A personal 360° view of applications of ‘biomimetic’ molecular recognition

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract Molecular recognition between biological molecules has formed the basis for innumerable applications in biotechnology for the last seven decades or so. Techniques such as affinity chromatography, solid‐phase and aqueous two‐phase extraction, affinity precipitation, biomimetic catalytic systems, biosensors and molecular imprinting all exploit ...

Bio‐Inspired, Zwitterionic Copolymers with Amphiphilic Character

Macromolecular Rapid Communications, EarlyView.
Zwitterionic copolymers based on arginine‐derived monomers are produced by xanthate‐supported photo‐iniferter reversible‐addition‐fragmentation chain‐transfer polymerization. Experiments in relevant conditions show that the designed (co)polymers hardly interact with biologically relevant proteins and enzymes such as bovine serum albumine (BSA), fetal ...

Poly(O‐Propargyl‐N‐Amino Carbamate), a Reactive Polymer to Underpin Biomedical Applications of Poly(acetylene)s

Macromolecular Rapid Communications, EarlyView.
We report here a new methodology to prepare functional poly(acetylene)s under aqueous conditions. This methodology is underpinned by poly(O‐propargyl‐N‐amino carbamate) (P1), a reactive poly(acetylene) carrying acyl hydrazines. Thus, P1 reacts with aldehydes to give functional poly(acetylene)s, including cationic, hydrophobic, and sugar‐loaded poly ...
