Conversion of D-phenylalanine to L-phenylalanine in humans.
Nippon Eiyo Shokuryo Gakkaishi, 1988 健康な女子2名にD-Phe-d5を8mg/kg体重, 他の必須アミノ酸および低タンパク質食とともに経口負荷し, 1, 4, 8時間後に採血した。血漿中の遊離フェニルアラニンをHPLCによりDL分割し, L画分について, Phe-d5/Phe-d0モル比をGC-MS-MIDにより測定した。この結果から, 血漿中のD-Phe-d5および, これから変換したL-Phe-d5の量を, 血漿中に天然に存在しているL-Phe-d0とのモル比として算出した。負荷後の血漿中のD-Phe-d5/L-Phe-d0モル比の最低は負荷1時間後の0.38 (被験者S: 0.16, T: 0.60の平均値), 最高は負荷4時間後の0.78 (S: 0.72, T: 0.84) であった。-Phe-d5/L-Phe ...

Advanced Science, EarlyView.Comparative genomics of Gondwana‐diverged Pila and Pomacea reveals parallel evolution of aerial oviposition. Convergent chromosomal rearrangements reshape regulatory landscapes within topologically associating domains. Lineage‐specific gene family expansions and viral‐derived perivitelline proteins (PV1) underpin desiccation resistance.

Multimodal Imaging Reveals Rapid Catecholamine Uptake and Release by Neutrophils
Advanced Science, EarlyView.We show that immune cells (neutrophils) synthesize, uptake, and store catecholamine neurotransmitters such as dopamine or adrenaline. They also release them in response to specific stimuli (serotonin), which we directly visualize using fluorescent nanosensors. We further demonstrate that catecholamines affect neutrophil functions (NETosis) and platelet

Evaluation of Taste and Hypoglycemic Activities of Phenylalanine Derivatives by Introducing Various Organic Compounds [PDF]
, 1991 Ｌ体およびＤ体のフェニルアラニンのＮ端に種々有機酸を導入した誘導体，およびＣ端にアルコールおよびアミンを導入した誘導体を合成した。合成した全サンプルについて，中間生成物を含めて呈味試験を行なったが，目的とする甘味あるいは塩から味は得られず，苦味あるいは酸味のものがほとんどだった。 さらにその一部について，ラットを用いた経口投与での血糖値抑制効果を測定したが，Perilloyl-Phe-OMe, Z-Val-Gly-OH及びBoc-Phe-D-Glucosamineのいずれからも，むしろ ...

Phenylalanine iminoboronates as new phenylalanine hydroxylase modulators
RSC Adv., 2014 Herein we report the discovery of new modulators of human phenylalanine hydroxylase (hPAH) inspired by the structure of its substrate and regulatorl-phenylalanine.

Advanced Science, EarlyView.Foliar spraying of CS‐CDs can form a film on the leaves of Brassica rapa, effectively reducing the enrichment and absorption of PS in the leaves, while increasing the biomass and nutrient content of the plants. In addition, CS‐CDs can also enrich the interfoliar microbial community and activate the plant's own defense metabolic pathways.
