T‐Shaped 8‐Aryl(ethynyl)‐Substituted Psoralens With Tunable Charge‐Transfer Absorption

European Journal of Organic Chemistry, Volume 29, Issue 8, 25 February 2026.
Starting from 8‐methoxypsoralen, new 8‐arylated and 8‐alkynylated psoralen derivatives are accessible by cross‐coupling. These T‐shaped π‐expanded chromophores are luminescent and photophysics reveal a highly polar excited state with tunable charge‐transfer character.

Novel Antifungal Scaffold Targeting Tubulin Overcomes Sclerotinia Sclerotiorum Resistance

Advanced Science, Volume 13, Issue 8, 9 February 2026.
Addressing pesticide resistance, novel chromone‐acylhydrazone hybrids targeting fungal tubulin are synthesized. Compound G24 potently inhibited S. sclerotiorum (EC50 = 0.21µg mL−1) and demonstrated enhanced field performance via microencapsulation, offering a sustainable strategy against resistance and for global food security.

Isoflavonoids and Epigenetic Modulation: Therapeutic Insights for Cancer Treatment

Chemistry &Biodiversity, Volume 23, Issue 2, February 2026.
Venn diagram illustrating the epigenetic roles of three phytochemical groups—flavonoids, isoflavonoids, and pterocarpans. ABSTRACT Isolavonoides represent the second largest subgroup of flavonoids and have an influence on critical molecular pathways and restore cellular homeostasis, through the reprogramming of epigenetic regulatory mechanisms.
