The anion radicals of stilbenes in the collisionless isolated phase were synthesized by electron attachment, and their dynamics were observed in real time on the femtosecond time scale. The observed coherent vibrational motion (approximately 42 cm(-1)) and the primary bond-twisting dynamics (approximately 650 fs) for the D2 state are on a vastly different time scale from that reported (approxim...

Currently, no drug is effective in delaying the cognitive impairment of Alzheimer’s disease, which ranks as one top 10 causes death worldwide. Hydroxylated stilbenes are active compounds that exist fruit and herbal plants. Piceatannol (PIC) gnetol (GNT), have extra hydroxyl group comparison to resveratrol (RSV), rhapontigenin (RHA) isorhapontigenin (isoRHA), were metabolized from PIC vivo conta...
