MODELS OF AMPHOTERICIN MEMBRANE CHANNEL BASED ON CONCERTED INTERMOLECULAR =C-H…O INTERACTIONS [PDF]

Annals of Mechnikov's Institute, 2012
To study the possibility for amphotericin to form membrane channel via intermolecular interactions mimicing the association mode of polyene macrolides in crystal structures we have built two channel models in vacuo: amphotericin B octamer and hexamer ...

Antioxidants in Plant‐Based Food Matrices: From Structure–Activity and Degradation Kinetics to Formulation Design

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 4, July 2026.
ABSTRACT Plant‐based antioxidants are widely incorporated into foods to retard oxidative deterioration and to deliver health‐related benefits. Yet, their in‐product and in vivo performance frequently diverges from predictions based on solution‐phase chemical assays, because matrix interactions, processing history, and host metabolism reshape both ...

Characterization of the biosynthetic gene cluster of the polyene macrolide antibiotic reedsmycins from a marine-derived Streptomyces strain

Microbial Cell Factories, 2018
Background Polyene antibiotics are important as antifungal medicines albeit with serious side effects such as nephrotoxicity. Reedsmycin (RDM) A (1), produced by marine-derived Streptomyces youssoufiensis OUC6819, is a non-glycosylated polyene macrolide ...

Bioconjugation Strategies for Revealing the Roles of Glycerophospholipids in Cells

ChemBioChem, Volume 27, Issue 11, 15 June 2026.
Glycerophospholipids are the main class of phospholipids, essential for membrane structure, compartmentalization, and cellular signaling. To study their roles, innovative probes and advanced bioconjugation strategies have been developed, including by de novo lipid synthesis and bioorthogonal conjugation chemistry.

Mechanically Assisted PO, PN, and PS Bonds Formation

Advanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
We present a general mechanochemical strategy for constructing PO, PN, and PS bonds via solvent‐free reactions of phosphoryl chlorides with O‐, N‐, and S‐nucleophiles. The method operates under mild conditions, shows broad substrate scope, and affords phosphates, phosphoramidates, and thiophosphates efficiently, providing a sustainable platform for ...

Charge Transport through Polyene Self-Assembled Monolayers from Multiscale Computer Simulations

, 2008
We combine first-principles density-functional theory with matrix Green’s function calculations to predict the structures and charge transport characteristics of self-assembled monolayers (SAMs) of four classes of systems in contact with Au(111 ...
