Linear and Two‐Dimensional Infrared Spectroscopy of the Multifunctional Vibrational Probe, 3‐(4‐Azidophenyl) Propiolonitrile. Deperturbing a Fermi Triad by Isotopic Substitution

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Linear infrared spectroscopy combined with isotope labeling and density functional theory unravels the origin of a Fermi triad in a multifunctional vibrational chromophore. Ultrafast 2DIR‐spectroscopy reports directly on the dynamics and the intramolecular vibrational energy flow pathways in the isotopically deperturbed system. Abstract Infrared probes

Synthesis of New N,N´‐Diarylureas and their Theoretical Study as Cannabinoid‐1 Receptor Inhibitors

ChemPlusChem, Accepted Article.
A series of new N,N′‐diarylureas is reported as potential cannabinoid‐1 (CB‐1) receptor inhibitors. The synthesis of the new N,N′‐diarylureas was achieved from the reaction of two substituted anilines with the aid of triphosgene. One aniline carries a pyrazol‐1‐yl or 1H‐1,2,3‐triazolyl or 2H‐1,2,3‐triazolyl propan‐2‐one group at position‐3, while the ...

Anthraquinone Sulfonates as Water‐Soluble Photocatalysts: Synthetic Applications and Perspectives

ChemPhotoChem, EarlyView.
The development of photochemistry in water is rapidly advancing, and the demand for water‐soluble photocatalysts is increasing. Accordingly, anthraquinone sulfonates are interesting options for the activation of organic molecules through H‐atom transfer, proton‐coupled electron transfer, or the generation of reactive oxygen species.

En Route Toward Sustainable Polycarbonates via Large Cyclic Carbonates

ChemSusChem, EarlyView.
The use of safe carbonylating agents, allowed by a suitable (bio)catalytic systems, affords the sustainable and green synthesis of large‐ring cyclic carbonates by reaction of renewables such as bio‐based diols. These carbonates are prone to ring‐opening polymerization paving the way for the production of circular aliphatic polycarbonates.

Dynamic Morphological Transformation and Self‐Assembly of DNA‐Functionalized Cellulose Nanocrystal Building Blocks

ChemSusChem, EarlyView.
We present a simple strategy for dynamic rod‐to‐sphere‐to‐rod morphological transformation and DNA‐mediated self‐assembly of cellulose nanocrystal building blocks into slab‐like architectures in colloidal states. Our approach opens a sustainable, scalable pathway toward biocompatible self‐assembly architectures that may address critical challenges in ...

A Workflow to Achieve Saturation of Fluorophore‐Conjugated Monoclonal Antibodies for Robust Comparison of Biomarker Expression

Cytometry Part A, EarlyView.
ABSTRACT Antibody titration is an important step in every cytometric workflow, with the goal being to determine antibody concentrations that ensure highly reproducible results. When aiming to compare antigen expression between samples using mean or median fluorescence intensity (MFI), reagents should be used at a saturating concentration so that ...

A 20‐color 21‐antigen flow cytometric assay for disease monitoring of T‐cell lymphoblastic leukemia

Cytometry Part B: Clinical Cytometry, EarlyView.
Abstract T‐lineage acute lymphoblastic leukemia (T‐ALL) is an aggressive neoplasm of immature T cells. Flow cytometry plays a critical role in the diagnosis and management of the disease. It is used to establish the abnormal immature T‐cell phenotype and to distinguish the early T‐cell precursor (ETP)‐ALL from more mature types at diagnosis.

Studies on the Stability and Microbial Biotransformation of Five Deschloroketamine Derivatives as Prerequisite for Wastewater‐Based Epidemiology Screening

Drug Testing and Analysis, EarlyView.
Microbial biotransformation and stability of deschloroketamine derivatives and their metabolites in WW by incubating parent compounds, rat urine, or rat feces showed that deschloroketamine parents and Phase I metabolite were still detectable and that Phase II metabolites decreased in peak areas.

Cost Minimized Immunoaffinity Purification of EPO and Its Analogs in Doping Control—A Step‐by‐Step Protocol for Human Urine and Blood

Drug Testing and Analysis, EarlyView.
A cost minimized immunoaffinity protocol was developed, which allows the direct purification of ERAs from human urine. After slight modification, the protocol is also applicable to serum and plasma and is fully compliant with WADA TD2024EPO. Compared to commercial EPO‐purification kits, the material costs are significantly lower.
