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.

Mycobacterial F420H2-Dependent Reductases Promiscuously Reduce Diverse Compounds through a Common Mechanism

Frontiers in Microbiology, 2017
An unusual aspect of actinobacterial metabolism is the use of the redox cofactor F420. Studies have shown that actinobacterial F420H2-dependent reductases promiscuously hydrogenate diverse organic compounds in biodegradative and biosynthetic processes ...
