Evaluation of antifungal and antimycotoxigenic activity of selected natural antioxidants against Fusarium culmorum: in vitro and in planta assays

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Fusarium culmorum causes Fusarium head blight (FHB) in cereals, leading to significant yield losses and contamination with type B trichothecene mycotoxins such as deoxynivalenol (DON) and its acetylated derivatives 3‐ADON and 15‐ADON.

Diacetylene‐Functionalized Glycan Mimetics for Receptor‐Mediated Cluster Imprinting in Model Membranes

open access: yesMacromolecular Rapid Communications, EarlyView.
Diacetylene‐containing glycan mimetics cluster upon selective lectin binding in GUVs. Subsequent irradiation leads to the formation of fluorescent polymer clusters, while non‐clustered glycan mimetics remain unaffected in the membrane. ABSTRACT The glycocalyx, a dense layer of glycoproteins and glycolipids on eukaryotic cells, is essential for cellular

Design, Synthesis, Cytotoxicity Assessment, and Molecular Docking of Novel Triazolopyrimidines as Potent Cyclin‐Dependent Kinase 4 Inhibitors

open access: yesChemistryOpen, EarlyView.
A novel series of 1,5‐dihydro‐[1,2,4]triazolo[4,3‐a]pyrimidines (5a–g) is synthesized and evaluated as potential CDK4 inhibitors. Compounds 5c and 5d exhibit strong cytotoxicity toward HepG2 and MCF‐7 cells with IC50 ≈ 1–2 µM, comparable to doxorubicin.
