The synthesis of (2S)-2-benzyloxymethyl-3-(2-fluoro-4-methoxyphenyl)- propionic acid, (2S)-2-benzyloxymethyl-3-(2-fluoro-4-methylphenyl)propionic acid and (2S)-2-benzyl-oxymethyl-3-(2,4-dimethylphenyl)propionic acid has been achieved by TiCl4 mediated alkylation of the corresponding (4R)-4-benzyl-3-[3-(2-fluoro-4-methoxyphenyl-, 2-fluoro-4-methylphenyl-, 2,4- dimethylphenyl-)propionyl]-2-oxazol...

The effects of transgalactosylated disaccharide (TD) intake on human fecal microflora and their metabolism were investigated in 12 Japanese males. TD is a mixture of sugars, galactosyl galactose, and galactosyl glucose, synthesized from lactose through the transgalactosylation reaction of Streptococcus thermophilus beta-galactosidase. Volunteers took 15 g of the test sugar daily for 6 days. The...

Although ibuprofen [2-(4-isobutylphenyl)-propionic acid] is one of the most widely consumed drugs in the world, little is known regarding its degradation by environmental bacteria. Sphingomonas sp. strain Ibu-2 was isolated from a wastewater treatment plant based on its ability to use ibuprofen as a sole carbon and energy source. A slight preference toward the R enantiomer was observed, though ...

Lactic acid bacteria (LAB) have a major role in biopreservation of foods because they are considered safe and are designated as GRAS (Generally Recognized as Safe) organisms. The preservative property of LAB is attributed to the combined action of a range of antimicrobial substances viz. lactic acid, acetic acid, propionic acid, carbon dioxide, hydrogen peroxide, bacteriocins and antifungal pep...

In the crystal of the title compound, C(11)H(12)O(4), inversion dimers arise from pairs of intermolecular O-H⋯O hydrogen bonds and C-H⋯O bonds further consolidate the packing. There is also a C-H⋯π contact between the benzene ring and the methyl-ene group.

The crystal structure of the title compound, C(10)H(9)Cl(2)NO(3), consists of dimers due to inter-molecular O-H⋯O hydrogen bonding forming an R(2) (2)(8) ring through the carboxyl- groups. These dimers are linked to each other by inter-molecular hydrogen bonds between the amine group and the adjacent carbonyl O atom. A single C-Cl⋯π inter-action is also observed between the chloro-substituted a...

Factors affecting in vitro ruminal bacterial VFA production were examined. Treatments consisted of high and low initial pH (6.7, 5.7), osmolality (600, 400 mOsm) and concentrations of acetic (40, 0 mM) and propionic acids (20, 0 mM). Response variables measured included the production of acetic, propionic and total VFA, total gas and methane. Initial pH affected (P less than .05) most variables...

The present study was planned with the objective to design and synthesis esters, amides and anilides derivatives of 3-benzamido propionic acid. All the derivatives were physicochemically characterized and the assigned structures were found to be in agreement with the spectral characterization. Further, in-vitro antimicrobial evaluation of synthesized compounds against Gram positive bacteria: St...
