2-(Allylthio)pyrazine (2-AP), which is effective in suppressing constitutive and inducible cytochrome P450 2E1 expression, exhibits hepatoprotective and chemopreventive effects. The radioprotective effects of 2-AP were examined in animals in association with the expression of microsomal epoxide

We demonstrate that the recently developed extended multi-state complete active space second-order perturbation theory (XMS-CASPT2) [Shiozaki et al., J. Chem. Phys., 2011, 135, 081106] provides qualitatively correct potential energy surfaces for low-lying excited singlet states of pyrazine, while
Characteristics and properties of metal-to-ligand charge-transfer excited states in 2,3-bis(2-pyridyl)pyrazine and 2,2'-bypyridine ruthenium complexes. Perturbation-theory-based correlations of optical absorption and emission parameters with electrochemistry and thermal kinetics and related Ab initio calculations.

A series of 2-(3-arylureido)pyridines and 2-(3-benzylureido)pyridines were synthesized and evaluated as potential modulators for amyloid beta (Aβ)-induced mitochondrial dysfunction in Alzheimer's disease (AD). The blocking activities of forty one small molecules against Aβ-induced mitochondrial
Chemical screening identifies an extract from marine Pseudomonas sp.-PTR-08 as an anti-aging agent that promotes fission yeast longevity by modulating the Pap1-ctt1+ pathway and the cell cycle.

Aging is a degenerative process characterized by progressive deterioration of cellular components, ultimately resulting in mortality, in which massive accumulation of reactive oxygen species (ROS) and advanced glycation end products (AGEs) are implicated as crucial factors. At the same time, natural

Transient absorption anisotropy is a well-established technique in time-resolved liquid phase spectroscopy. Here, we show how the technique is applied in the gas phase for time-resolved photoelectron spectroscopy and what type of additional information can be obtained as compared to other
