We report the rational design and synthesis of C2-modified DGJ analogues to improve the selective inhibition of human GALA over other glycosidases. We prepare these analogues using a concise route from non-carbohydrate materials and demonstrate the most selective inhibitor 7c (∼100-fold) can act in Fabry patient cells to drive reductions in levels of the disease-relevant glycolipid Gb3.

Various photoactive molecules contain motifs built on aza-aromatic heterocycles, although a detailed understanding of the excited state photophysics and photochemistry in such systems is not fully developed. To help address this issue, the non-adiabatic dynamics operating in azanaphthalenes under hexane solvation was studied following 267 nm excitation using ultrafast transient absorption spectroscopy. Specifically, the species quinoline, isoquinoline, quinazoline, quinoxaline, 1,6-naphthyridine, and 1,8-naphthyridine were investigated, providing a systematic variation in the relative positioning of nitrogen heteroatom centres within a bicyclic aromatic structure.

Renewable electricity-driven electrochemical reduction of CO2 offers a promising route for production of high-value ethanol. However, the current state of this technology is hindered by low selectivity and productivity, primarily due to limited understanding of the atomic-level active sites involved in ethanol formation. Herein, we identify that the interfacial oxygen vacancy-neighboring Cu (Ov-Cu) pair sites are the active sites for CO2 electroreduction to ethanol.

Background: The multifunctional cytokine interleukin-6 (IL-6) plays a pivotal role in chronic and acute inflammatory responses, underscoring the importance of accurately determining IL-6 levels for early diagnosis, prevention, and treatment of inflammation.
Results: This study developed a versatile and innovative single-particle surface-enhanced Raman spectroscopy (SERS) sensing platform for the precise and sensitive quantification of IL-6 in complex samples using a novel one-pot synthesized, silver ions-doped three-dimensional porous gold microparticles (PGMs) with abundant hot spots for robust SERS enhancement. By rationally designing rich cytosine-Ag-cytosine base pairs between IL-6 aptamers and complementary chains on the PGMs, we harnessed the SERS-enhancing effect to achieve highly sensitive and specific IL-6 quantification within a wide range of 10 to 10 mg/mL and a limit of detection (LOD) of 0.

Electrolysis of seawater for hydrogen (H) production to harvest clean energy is an appealing approach. In this context, there is an urgent need for catalysts with high activity and durability. RuO electrocatalysts have shown efficient activity in the hydrogen and oxygen evolution reactions (HER and OER), but they still suffer from poor stability.

Epigenetic dysregulation plays a pivotal role in the initiation and progression of various cancers, influencing critical processes such as tumor growth, invasion, migration, survival, apoptosis, and angiogenesis. Consequently, targeting epigenetic pathways has emerged as a promising strategy for anticancer drug discovery in recent years. However, the clinical efficacy of epigenetic inhibitors, such as HDAC inhibitors, has been limited, often accompanied by resistance.
