Pharmacogenetic CYP2B6 variants affect steroid hormone metabolism in human breast cancer cells

British Journal of Clinical Pharmacology, EarlyView.
Common genetic CYP2B6 variants correlate with adverse breast cancer outcome. The oestrogen metabolites estriol and 16‐epiestriol, which are formed downstream of CYP2B6‐catalysed 16α/β‐hydroxytestosterone, may be linked to elevated breast cancer risk and might increase due to the demonstrated CYP2B6 variants‐related metabolic shifts.

Porous Carbon Materials for Carbon Dioxide Capture

Carbon Energy, EarlyView.
This work aims to address the current status and challenges associated with the regulation of pore structures, as well as the influence of pore structures on CO2 capture. Systematic quantitative analysis of structure–property relationships, combined with machine learning approaches, can effectively evaluate the contributions of structural ...

Aromatization and isomerization of 1-hexene over alkali-treated HZSM-5 zeolites: Improved reaction stability

, 2008
The HZSM-5 zeolites with micro-mesopore hierarchical porosity have been prepared by the post-synthesis of alkali treatment, and tested in the aromatization and isomerization reactions of 1 -hexene in a continuous flow fixed bed.

Oxidative Fast Pyrolysis Enabling Autothermal Production of Porous Functionalized Biochar and Anhydrosugar/Phenol‐Rich Bio‐Oil From Biomass

Carbon Energy, EarlyView.
Oxidative fast pyrolysis of biomass enables autothermal production of value‐added products. ABSTRACT Oxidative fast pyrolysis can potentially overcome the heat‐supply bottleneck of conventional fast pyrolysis by enabling autothermal operation while also tailoring product quality through controlled oxygen addition.

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

Mild N‑Arylation of Sulfoximines With (Hetero)aryl Chlorides Enabled by α‐Methylnaphthyl‐tBuBrettPhos Palladium Triflate

Chemistry – A European Journal, EarlyView.
A readily accessible, air‐ and moisture‐stable palladium precatalyst, [Pd(1‐MeNAP)(tBuBrettPhos)]OTf, enables the direct N‐arylation of NH‐sulfoximines with (hetero)aryl chlorides under exceptionally mild conditions ideal for late‐stage diversification of drug‐like scaffolds.

Tetrazine Ligation in Living Systems: Beyond Fast Kinetics to Effective Bioorthogonality

Chemistry – A European Journal, EarlyView.
Rapid reaction kinetics (k2) alone do not ensure successful tetrazine ligation in living systems. This review introduces ‘effective orthogonality’—focusing on chemical survival, availability, and encounter—as a practical framework. We highlight how bottlenecks shift from cellular sinks to in vivo delivery limits, offering design strategies for reliable
