Iron Catalyzed Aryl–Aryl Kumada Cross‐Coupling: A Mechanistic and Computational Investigation

Angewandte Chemie, EarlyView.
Despite intense interest, the mechanism of iron‐catalyzed aryl–aryl cross‐coupling remains poorly understood. Combining Mössbauer spectroscopy, kinetics analysis, and DFT computations these studies reveal a novel Fe(I)/Fe(II)/Fe(III) catalytic for aryl–aryl cross‐coupling mediated by an Fe(II) PCNHCP Pincer complex. These findings close a key knowledge

Biphenyls, a new class of compound that inhibits plateletactivating factors.

Chemical and Pharmaceutical Bulletin, 1990
Honokiol (1), a constituent of Magnoliae cortex, and related synthetic biphenyls inhibited the platelet aggregation induced by a few aggregating agents. In particular, compounds 3, 5, and 10 had an inhibitory effect on platelet activating factor (PAF), which provides a new class of PAF inhibitor.

Record‐High Performance Hyperfluorescent OLEDs Achieved via Electronic Structure Control of Chlorine‐Diversified MR‐TADF Emitters

Advanced Science, EarlyView.
A late‐stage diversification strategy for the benchmark MR‐TADF emitter ω‐DABNA enables precise electronic structure control via chlorine‐activated functionalization. The resulting derivatives achieve tunable emission from 523 to 533 nm with record‐high EQE1000 up to 34.0% and excellent color purity (CIEy = 0.70–0.73), establishing a versatile platform

ROR-γ drives androgen receptor expression and represents a therapeutic target in castration-resistant prostate cancer. [PDF]

, 2016
The androgen receptor (AR) is overexpressed and hyperactivated in human castration-resistant prostate cancer (CRPC). However, the determinants of AR overexpression in CRPC are poorly defined.
