The title compound, C(10)H(11)NO(5), is of inter-est with respect to its anti-dyslipidemic activity. It was prepared by reaction of 4-nitro-phenol with ethyl 2-bromo-2-methyl-propionate followed by ethyl ester hydrolysis. In the crystal, mol-ecules are linked into centrosymmetric dimers by inter-molecular O-H⋯O hydrogen bonds and the dimers are connected into chains by weak C-H⋯O inter-actions....
The title compound, C(10)H(11)NO(4)S, is of inter-est with respect to its biological activity. The mol-ecules are linked into centrosymmetric dimers by inter-molecular O-H⋯O hydrogen bonds and the dimers are further connected into chains by weak C-H⋯O inter-actions.
In this research at the first 2-amino-3-(3,4-dihydroxyphenyl)-2-methyl-propanoic acid drug and its fullerene derivative were optimized. NMR calculations for the complexes were carried out at the B3LYP/6-31G*quantum chemistry level. Different parameters such as energy levels, the amount of Chemical Shift in different atoms, the amount of HOMO/LUMO, chemical potential (µ ), chemical hardness (η)...
Caffeic acid phenethyl ester (CAPE) is a bioactive component isolated from propolis. A series of CAPE analogues was synthesized and their antiradical/antioxidant effects analyzed. The effect of the presence of the double bond and of the conjugated system on the antioxidant effect is evaluated with the analogues obtained from 3-(3,4-dihydroxyphenyl) propanoic acid. Those obtained from 2-(3,4-di...
This study was an add-on study to the National Air Emission Monitoring Study (NAEMS). The objective of this study was to measure odor emissions and corresponding concentrations and emissions of target odorous gases. Odor and odorous gas measurements at four NAEMS sites (dairy barns in Wisconsin-WI5B and Indiana-IN5B, swine finisher barn in Indiana-IN3B and swine gestation/farrowing barns in Iow...
