2,3,4,5,6-Pentafluoro-trans-cinnamic acid
The title compound, C9H3F5O2, crystallizes as O-H⋯O hydrogen-bonded carb-oxy-lic acid dimers that, together with C-H⋯F inter-actions and O⋯F [2.8065 (13) and 2.9628 (13) Å] and F⋯F [2.6665 (11), 2.7049 (12) and 2.7314 (12) Å] contacts, form a sheet-like structure. The sheets are stacked via short π-π inter-actions [centroid-centroid distance = 4.3198 (11) Å]. An intra-molecular C-H⋯F inter-acti...
متن کاملEffects of trans-Cinnamic Acid on Expression of the Bean Phenylalanine Ammonia-Lyase Gene Family.
Using DNA probes specific for the three members of the bean (Phaseolus vulgaris L.) phenylalanine ammonia-lyase (PAL) gene family, we have studied the effects of the product of the PAL reaction, trans-cinnamic acid (CA), on the appearance of individual PAL transcripts in suspension cultured bean cells. Concentrations of CA in excess of 10(-4) molar inhibited appearance of elicitor-induced trans...
متن کاملEthanol fermentation in an immobilized cell reactor using Saccharomyces cerevisiae.
Fermentation of sugar by Saccharomyces cerevisiae, for production of ethanol in an immobilized cell reactor (ICR) was successfully carried out to improve the performance of the fermentation process. The fermentation set-up was comprised of a column packed with beads of immobilized cells. The immobilization of S. cerevisiae was simply performed by the enriched cells cultured media harvested at e...
متن کاملChloroperoxidase-catalyzed halogenation of trans-cinnamic acid and its derivatives.
Several 2,3-unsaturated carboxylic acids, such as trans-cinnamic acid and its derivatives, were found to be halogenated by chloroperoxidase of Caldariomyces fumago in the presence of hydrogen peroxide and either Cl- or Br-. Cinnamic acid, 4-hydroxycinnamic acid, 4-methoxycinnamic acid, and 3,4-dimethoxycinnamic acid were suitable substrates of chloroperoxidase, and were converted to 2-halo-3-hy...
متن کاملEffect of Trans-cinnamic Acid on Cognitive Deficit, Cell Density of CA1/CA3 Regions, and Cholinergic Activity of Hippocampus in Trimethylettin Model of Alzheimer's Disease
Introduction: Trimethyltin (TMT) intoxication is associated with damage to the cholinergic system in the hippocampus. The aim of this study was to evaluate the effect of trans-cinnamic acid on cognitive deficit and cell damage in CA1/CA3 regions of the hippocampus, as well as measure the activity of acetyl choline esterase (AChE) in the hippocampus of a rat model of Alzheimer’s disease (AD). Ma...
