Dietary Ergothioneine as a Novel Anti‐Aging Nutraceutical: Mechanisms, Bioavailability, and Future Perspectives

open access: yesFood Frontiers, Volume 7, Issue 3, May 2026.
ABSTRACT Ergothioneine (EGT), a natural thiol derivative, has gained attention as a geroprotective nutraceutical. Preclinical research shows EGT scavenges free radicals, maintains mitochondrial integrity, slows telomere erosion, and regulates proteostasis via autophagy and senescent cell clearance.

Photocatalytic Cross‐Coupling of Phenols and Heteroaryl Halides With Machine Learning‐Guided Reaction Prediction

open access: yesAngewandte Chemie, Volume 138, Issue 16, 13 April 2026.
Photocatalytic cross‐coupling: A redox‐neutral photochemical method enables direct C(sp2)─C(sp2) bond formation between phenols and heteroaryl halides using an organic dye and base. Complementary radical generation allows efficient cross‐coupling in up to 91% yield. Mechanistic studies, DFT, HTE, and machine learning rationalize and predict reactivity,

Matsupexole: A novel nonergot dopamine receptor agonist with sustained efficacy in a rat model of Parkinson's disease and limited off‐target activity

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 10, Page 2518-2532, May 2026.
Background and Purpose Dopamine receptor agonists, particularly targeting the dopamine D2L receptor (D2LR), have been used to treat Parkinson's disease (PD). However, valvular heart disease and somnolence, mainly caused by activating the serotonin 5‐HT2B receptor (5‐HT2BR) and dopamine D3 receptor (D3R), respectively, currently challenge their clinical
