Pathways for Intramolecular Relaxation in S1 Benzene [PDF]

open access: yes, 1990
Sub-Doppler spectra of various one- and two-photon vibronic bands of benzene are discussed and analysed to determine the pathways of intramolecular relaxation for S1 benzene. New results are presented for the 14011011622 band of C6H6 and the 1401102 band

Binuclear Copper‐Dependent Oxidative Enzymes Involved in Fungal Natural Product Modifications

open access: yesJournal of the Chinese Chemical Society, EarlyView.
This article summarizes recent biochemical characterizations of a new enzyme family named by the authors as binuclear copper‐dependent oxidative enzymes (BiNCOs). Found in fungal natural product biosynthesis, BiNCOs catalyze diverse CH functionalization reactions, including C(sp3)H halogenation, C(sp3)H hydroxylation, C(sp3)O macrocyclization, and ...

Biomolecular Interaction Prediction in the Pre‐ and Post‐AlphaFold Era: The 8th CAPRI Evaluation

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT We report on the 8th CAPRI Evaluation period, capturing the assessment of CAPRI Rounds 47 to 55 (excluding the CASP and COVID‐related Rounds), which have witnessed the transition to AI‐driven prediction tools such as AlphaFold and related alternatives. The prediction Rounds in this evaluation are characterized by a high level of difficulty due

Oxaziridines: Versatile Reagents in Modern Organic Synthesis

open access: yesThe Chemical Record, EarlyView.
Being capable of transferring an O atom and N‐group/atom, oxaziridines are considered multitasking agents. These are employed for diverse organic transformations, such as epoxidation of olefins, α‐ and γ‐hydroxylation/amination of carbonyl compounds, oxidation of sulfides, [3+2]cycloaddition with unsaturated systems.

Discovery of industrially relevant oxidoreductases [PDF]

open access: yes, 2020
Oxidoreductases are a family of enzymes that have a role in various reduction, oxidation, and oxyfunctionalization reactions. They cleave chemical bonds to facilitate electron transfer from a reduced organic substrate (donor) to another chemical compound

Non‐canonical PKG1 regulation in cardiovascular health and disease

open access: yesBritish Journal of Pharmacology, EarlyView.
It is well established that the cyclic GMP‐dependent protein kinase I (PKG1) is canonically activated by cyclic guanosine monophosphate (cGMP), enabling its regulation of vascular tone, cardiac function and smooth muscle homeostasis. However, diverse non‐canonical stimuli of PKG1 have also been identified.

Inter- and Intramolecular Aryl-Aryl-Interactions in Partially Fluorinated Ethylenedioxy-Bridged Bisarenes [PDF]

open access: yes, 2020
Several ethylenedioxy-bridged bisarenes with a variety of type and number of aryl groups were synthesized to study non-covalent dispersion-driven inter- and intramolecular aryl-aryl-interactions in the solid state and gas phase.

Pretreatment of keratinocytes with Galactomyces ferment filtrate (GFF) promotes stress resiliency in an in vitro oxidative stress model

open access: yesInternational Journal of Cosmetic Science, EarlyView.
GFF pretreatment enhances keratinocyte protection against oxidative stress by mitigating stress‐induced biomolecular changes and gene expression dysregulation. GFF‐pretreated keratinocytes maintain healthy epidermal biology post‐stress, preserving mitochondrial function and proliferative capacity.
