Quinoa Protein Concentrate as a Platform for the Protection and Controlled Delivery of Resveratrol and Tocopherol

open access: yesSustainable Food Proteins, Volume 4, Issue 2, June 2026.
Graphical abstract illustrating the development of quinoa protein (QP) nanocarriers for the encapsulation of resveratrol (RSV) and tocopherol (TOC). ABSTRACT The objective of this work was to generate and characterize complexes of quinoa proteins (QP) with either resveratrol (RSV) or tocopherol (TOC) whose dimensions fell into the nanoscale.

Allylsilanes in the synthesis of three to seven membered rings: the silylcuprate strategy

open access: yesBeilstein Journal of Organic Chemistry, 2007
Addition of low order phenyldimethylsilylcyanocuprates to allenes followed by "in situ" reaction of the intermediate silylcuprate with electrophiles ("the silylcuprate strategy") provides new routes for the synthesis of functionalised allylsilanes, which

Exploring 6‐Hydroxy‐3‐Aryl/Heteroarylcoumarins as Promising Candidates Against Trypanosoma cruzi

open access: yesChemMedChem, Volume 21, Issue 9, 14 May 2026.
New therapies are urgently needed for Chagas disease, and screening of 6‐hydroxy‐3‐aryl/heteroarylcoumarin derivatives identified highly selective compounds with potent activity against T. cruzi. In particular, derivative 1f showed submicromolar trypomastigote potency, dual‐stage activity, and inhibition of amastigote‐to‐trypomastigote differentiation,

Nucleobase Stacking Sustained by Pt−Pt Interactions

open access: yesChemistryEurope
This article reports the use of metal–metal interactions as a way to induce nucleobase stacking in a dinucleotide chain. We synthetized and study a series of C,N‐cyclometallated platinum(II) binuclear complexes derived from 6‐phenylpurine dinucleotide 1 ...

Highly Versatile Hydrogenative Functionalizations of Phthalimides Catalyzed by an Ag‐Alumina Zeolite Nanocomposite: One‐Pot Synthesis of 3‐Substituted Isoindolinones

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
Heterogeneous‐catalyzed selective and versatile hydrogenative functionalizations of phthalimides have been developed for the first time. By using a solid nanocomposite formed by [Ag/Al2O3] material in combination with [H‐BETA] zeolite as cocatalyst, a broad range of 3‐functionalized isoindolinones have been accesed in one‐pot from phthalimides, H2 and ...

Structural Features and Reaction Profile of an Evolved Unspecific Peroxygenase From Candolleomyces Aberdarensis

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
Fungal unspecific peroxygenases (UPOs) are promiscuous heme‐containing enzymes that selectively oxyfuntionalize C‐H bonds. Structural and enzymatic reaction studies of an evolved UPO mutant from Candolleomyces (Psathyrella) aberdarensis (PabUPO‐I) reveal how the heme channel architecture dictates the regioselectivity towards alkanes, fatty acids and ...

Tuning the Twist by Molecular Design: A New Strategy for Hexabenzocoronene‐Containing Helical Twistacene

open access: yesChemistry – A European Journal, Volume 32, Issue 17, 5 May 2026.
An efficient Scholl–based strategy enables precise control of the C–C bond to access the first hexabenzocoronene–containing helical twistacene (NG2). The resulting nanographene shows pronounced helical distortion, high stability, enhanced solubility, and promising redox and optoelectronic properties.
