Intrinsic specificity of a ‘core’ TIP60 acetyltransferase complex in Drosophila

open access: yesThe FEBS Journal, Volume 293, Issue 11, Page 3259-3273, June 2026.
The intrinsic substrate selectivity of the Drosophila TIP60‐core acetyltransferase was determined using synthetic nucleosome arrays. Targeted mass spectrometry revealed site‐specific acetylation of histones H2A, H2A.V, and H4, uncovering distinct acetylation rates and patterns across individual lysines.

{Silk@Hyaluronic‐Acid} Hybrids: Efficient Antioxidants Against DPPH● With Resilience Against ●OH

open access: yesApplied Research, Volume 4, Issue 3, June 2025.
Three hybrid materials were synthesized and fully characterized, SFd@GLA, SFd@GLAM, and GLA@SFd@GLAM. All three hybrid materials demonstrated reusability against DPPH radicals, 10 cycles of reusability. Against OH radicals they exhibit a protective lattice and again reusability. ABSTRACT Antiradical, antioxidant agents are of great importance in health,

Α {Silk@Gallic‐Acid} hybrid material with controllable antioxidant hydrogen‐atom‐transfer activity

open access: yesApplied Research, Volume 3, Issue 5, October 2024.
A silk@gallic acid hybrid material was synthesized and fully characterized. It shows antioxidant activity and long‐term reusability. It is demonstrated SFd@GA can be employed for at least 15 cycles retaining up to 98% of its HAT efficiency. Abstract Silk fiber, often acclaimed as the pinnacle of textile materials, finds contemporary applications in the

Visible‐Light‐Driven Germyl Radical Generation via EDA‐Catalyzed ET–HAT Process

open access: yesChemistry – A European Journal, Volume 30, Issue 41, July 19, 2024.
Facile generation of germyl radical was achieved by using photo‐excited electron transfer (ET) in an electron donor‐acceptor (EDA) complex to drive hydrogen atom transfer (HAT) from germyl hydride (R3GeH). Using catalytic amounts of commercially available thiol and benzophenone derivatives, the ET‐HAT cycle smoothly proceeds upon blue‐light irradiation

TBADT‐Mediated Photocatalytic Stereoselective Radical Alkylation of Chiral N‐Sulfinyl Imines: Towards Efficient Synthesis of Diverse Chiral Amines

open access: yesChemistry – A European Journal, Volume 30, Issue 24, April 25, 2024.
This article presents a photocatalytic method for the stereoselective radical alkylation of chiral sulfinyl imines. It utilizes non‐prefunctionalized radical precursors and TBADT as a direct HAT photocatalyst, yielding diverse chiral amines with excellent diastereoselectivity under mild conditions.

C‐Centered radical intermediates for C(sp3)‐H bonds functionalization: An emerging approach towards alkyl thiocyanates

open access: yesEuropean Journal of Organic Chemistry, Volume 27, Issue 8, February 26, 2024.
This Review focuses on the recent strategies developed for the thiocyanation of C(sp3)−H bonds via the formation of a C‐centered radical intermediate. These approaches have provided easy access to original thiocyanate products of high interest. Abstract Organic thiocyanates are an important class of compounds because they are present in several ...

Visible‐Light‐Driven Cyclizations

open access: yesAdvanced Synthesis &Catalysis, Volume 366, Issue 4, Page 635-697, February 20, 2024.
Abstract In recent years, the interest to develop cyclizations promoted by visible light has been gaining a lot of attention due to its sustainability aspect. In this review, we summarize the most important advances in this period by describing the methods used to generate different ring sizes, while focusing on the mechanistic details of these ...
