Journal of hazardous materials, 192(3), 1633-1640 (2011-07-29)
Microbial degradation of the chiral 2-phenylbutyric acid (2-PBA), a metabolite of surfactant linear alkylbenzene sulfonates (LAS), was investigated using both racemic and enantiomer-pure compounds together with quantitative stereoselective analyses. A pure culture of bacteria, identified as Xanthobacter flavus strain PA1

Journal of chromatography. A, 1163(1-2), 177-189 (2007-07-07)
A systematic study was made to explain the large improvements in separation performance and capacity of basic compounds at alkaline conditions. The adsorption of three probe components was investigated on four alkaline-stable silica-based C18 columns at three different pH-levels: 3

The adsorption behaviour of the enantiomers of 2-phenylbutyric acid on the chiral stationary phase (CSP) Kromasil CHI-TBB was studied using hexane/MTBE (90/10) as eluent. Adsorption isotherms were acquired at 40 different enantiomer concentrations in the interval between 7.6 microM and
The preparation and first application of a polymer-supported ?Evans? oxazolidinone.
Allin SM and Shuttleworth SJ.
Tetrahedron Letters, 37(44), 8023-8026 (1996)

Anticancer research, 19(3A), 1971-1976 (1999-09-02)
The objective of this investigation was to study the relationship between histone acetylation and growth inhibition by 4-phenylbutyrate and structural analogs. Inhibition of growth of DS19 mouse erythroleukemia cells and K562 human leukemic cells by 4-phenylbutyrate did not appear to
H Bohner et al.
International journal of clinical pharmacology and therapeutics, 35(3), 117-122 (1997-03-01)
Eighteen volunteers have been treated with different oral formulations of butamirate citrate according to 2 randomized 2-way crossover designs. In the first study (study I) the test preparation was a syrup (Demotussol Hustensirup, Demopharm), and the reference preparation was a

On a column with bovine serum albumin (BSA) immobilized covalently to silica, the adsorption isotherms of the enantiomers of mandelic acid, tryptophan, 2-phenylbutyric acid, and N-benzoylalanine are measured using a buffered mobile phase. Knowing the amount of BSA immobilized on
Conformational studies of 2-methyl-3-phenylpropionic acid, 2-phenylbutyric acid and their methyl esters by NMR spectroscopy.

M T Tsamis et al.
Journal of chromatography, 277, 61-69 (1983-10-14)
Two chromatographic methods which allow the measurement of 2-phenylbutyric acid in serum are described: a gas chromatographic, after silylation, and a reversed-phase high-performance liquid chromatographic. The liquid chromatography with a fluorescent detection, after derivatization by 4-bromomethyl-7-methoxycoumarin, is ten times more

Phenylalanine deletion at position 508 of the cystic fibrosis transmembrane conductance regulator (DeltaF508-CFTR), the most common mutation in cystic fibrosis (CF), causes a misfolded protein exhibiting partial chloride conductance and impaired trafficking to the plasma membrane. 4-Phenylbutyrate corrects defective DeltaF508-CFTR
Shen Li et al.
Journal of the American Chemical Society, 130(27), 8584-8585 (2008-06-13)
A highly efficient iridium-catalyzed hydrogenation of alpha,beta-unsaturated carboxylic acids has been developed by using chiral spiro-phosphino-oxazoline ligands, affording alpha-substituted chiral carboxylic acids in exceptionally high enantioselectivities and reactivities.

Current chemotherapeutic and butyrate therapeutics that induce fetal hemoglobin expression generally also suppress erythropoiesis, limiting the production of cells containing fetal hemoglobin (F cells). Recently, selected short-chain fatty acid derivatives (SCFADs) were identified that induce endogenous gamma-globin expression in K562

Reactivation of fetal hemoglobin (HbF) expression using pharmacological agents represents a potential strategy for the therapy of beta-thalassemia, sickle cell disease, HbE and other beta-hemoglobinopathies. However, the drugs currently available have low efficacy and specificity and are associated with high
