Antioxidant phenylacetic acid derivatives from the seeds of Ilex aquifolium.
Reversed-phase preparative HPLC analysis of the methanol extract of the seeds of Ilex aquifolium afforded two antioxidant phenylacetic acid derivatives, 2,4-dihydroxyphenylacetic acid (1) and 2,4-dihydroxyphenylacetic acid methyl ester (2). The structures were determined by spectroscopic methods. In the DPPH assay for antioxidant activity, the IC(50) values of 1 and 2 were 1.50 x 10(-3) and 2.5...
متن کاملDirect amidation of non-activated phenylacetic acid and benzylamine derivatives catalysed by NiCl2
This paper describes an eco-friendly and efficient direct amidation of benzylamine and phenylacetic acid derivatives in the presence of 10 mol% NiCl2 as catalyst without any drying agent. For the different phenylacetic acid and benzylamine derivatives, the direct catalysed amidation gave moderate-to-excellent yields in toluene. The steric and electronic effects of substituent groups on the phen...
متن کاملThe bacterial oxidation of phenylacetic acid.
The bacterial oxidation of aromatic compounds closely related in chemical structure may proceed by different pathways. Thus, while the main features of the breakdown of mandelic acid are established, those of phenylacetate are not, except insofar as it is known to follow a different route (Stanier, 1950). The divergencies may possibly indicate a difference in the mode of ring fission; and since...
متن کاملVery Low Pressure Pyrolysis of Phenylacetic Acid
Recent reviews on the thermochemistry of organic radicals in the gas phase,'*2 have pointed out the necessity of a reassessment of the heat of formation of the hydroxycarbonyl radical and the corresponding bond-dissociation energy Ed in formic acid. Based on a re-evaluation of the early work of Back and S e h ~ n , ~ McMillen and Golden,' have recommended A,H('CO,H) = -209.2 kJ mol-'; however, ...
متن کاملProduction of phenylacetic acid by anaerobes.
We tested 388 strains of anaerobes from 17 genera for the production of phenylacetic acid. The compound was found in only two genera (Bacteroides and Clostridium) but not within all the species of these genera.
