Asian Journal of Organic Chemistry, EarlyView.meso‐Free porphyrinoids are recognized as a versatile platform for further functionalization and oligomerization. The synthesis and characteristic features of such meso‐free porphyrinoids are reviewed. Abstract meso‐Unsubstituted (meso‐free) porphyrins have been an effective platform for creating versatile peripherally functionalized porphyrins and ...

Hydrogen Binding Energy Is Insufficient for Describing Hydrogen Evolution on Single‐Atom Catalysts
Angewandte Chemie, EarlyView.The research introduces a refined volcano model that incorporates both ΔGH* and ΔGHO*, addressing the limitations of traditional H models by factoring in HO* adsorption effects. Furthermore; the subquestion was discussed: Whether the metal site in SACs is the only active site?

Longitudinal Metabolomics in Amyotrophic Lateral Sclerosis Implicates Impaired Lipid Metabolism
Annals of Neurology, EarlyView.Objective Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by altered metabolome and energy homeostasis, manifesting with body mass index changes and hypermetabolism—both prognostic of disease progression and survival.

ChemBioChem, Volume 23, Issue 23, December 5, 2022., 2022 Fifteen new dinuclear arene‐ruthenium (II)‐BODIPY conjugates were synthesized. Despite a fluorescence quenching effect, these conjugates can be used as fluorescent tracers. Their antiparasitic activity but also their toxicity against healthy human foreskin fibroblasts (HFFs) was reduced compared to the parent ruthenium compounds.

Advances and Challenges in Low‐Temperature Upcycling of Waste Polyolefins via Tandem Catalysis
Angewandte Chemie, EarlyView.This review presents an overview of recent advances in mild catalytic transformations of polyolefins, emphasizing the kinetic and thermodynamic interplay between endothermic C─C bond cleavages and the exothermic formation of new C─H, C─C, and C─O bonds.

Advanced NanoBiomed Research, EarlyView.This study demonstrates that combination of phosphosensitizer‐conjugated chitosan nanoparticles and ferroptosis inducer RSL3 increases cell death in mesenchymal breast cancer cells. Data suggests that this is attributed to variations in ferroptosis‐related protein expression, lipid peroxydation and mitochondrial function.

Oxidative Rearrangements of the Alkaloid Intermediate Geissoschizine
Angewandte Chemie, EarlyView.19E‐geissoschizine is a key precursor in the biosynthesis of monoterpene indole alkaloids such as strychnine, ibogaine, and vinblastine. Using enzymatic assays and gene silencing, three CYPs were identified from C. roseus that oxidize this compound to four alkaloid scaffolds: strychnos, sarpagan, akuammiline, and mavacurane. Mutational analysis reveals
