Chemistry involves the study of all things chemical – chemical processes, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations, Safety of 2-Phenylbutanoic acid.

The benzisoxazole and pyrimidine moieties are essentially planar and the dihedral angle between these planes is 5.6 (1)-degrees. The piperidine ring is in a slightly distorted chair conformation, while the tetrahydropyridine moiety shows a half-chair conformation. The crystal stucture is stabilized by a hydrogen bond between the H atom on position 4 of the benzisoxazole and the O atom of the pyrimidinone of a translated (x, y-1, z) molecule [C…O = 3.372 (7), H…O = 2.327 angstrom, C-H…O = 161.6-degrees].

Herein, we have designed various benzisoxazole acetamide derivatives with and without glycine spacer as DPP-IV inhibitors. Compounds 9a-d and 11a-e were synthesized and screened for their in vitro DPP-IV inhibition. Compounds 11a and 11c showed moderate activity for DPP-IV inhibition, whereas other remained inactive at 25-200 mu M concentrations. DPP-IV inhibition can be a good strategy for modulating diabetes and cancer; hence, we have screened compounds 9a-d and 11a-e for their anticancer activity using MTT assay against A549 and MCF7 cell lines. Compounds 9a-d without glycine spacer have shown good anticancer activity compared to compounds 11a-e with glycine spacer. Compound 9b has shown moderate activity with IC50 values 4.72 +/- 0.72 and 4.39 +/- 0.809 mu M against A549 and MCF7 cell lines, respectively. Interestingly, compound 9c with cyano group has shown very good anticancer activity with IC50 2.36 +/- 0.34 mu M against MCF7 cell line as compared to fluorouracil with IC50 45.04 +/- 1.02 mu M.

Direct computation of the pi-current density, that is, the ‘ring current’, of anthranil (1) and its isomers 1,2-benzisoxazole (2) and benzoxazole (3) reveals different patterns of current flow: isomers 2 and 3 sustain strong benzene-like currents in the six-membered and bifurcated flow in the five-membered ring, whereas, in keeping with its lower thermodynamic stability, 1 has only a perimeter circulation without separate monocycle currents. Although the ring current criterion does not offer a sharp distinction between 2 and 3, their difference in thermodynamic stability is identical to that between isoxazole (4) and oxazole (5) suggesting an aromaticity order 1 < 2 approximate to 3.

Antibody 16E7 catalyzes the carbon protonation of enol ether 2 to hemiacetal 3, and the carbon deprotonation of benzisoxazole 7 to phenol 8. This antibody shows an extreme case of hysteresis, requiring several hours to reach full activity. Antibody 16E7 was expressed as recombinant chimeric Fab in Escherichia coli. A model for the three-dimensional structure was produced by homology modeling and used for a docking procedure to obtain models for antibody-ligand complexes. Site-direct mutagenesis of Glu(L39), identified as a possible catalytic residue by the model, to either glutamine or alanine abolished catalysis, showing that both the protonation reaction of enol ether 2 and the deprotonation of benzisoxazole 7 are promoted by the same residue. The model furthermore suggested that substrate access to the catalytic site might be hindered by a flexible HCDR3 loop held in closed position by a hydrogen bond between Ser(H99) and Glu(L39), which could explain the observed hysteresis effect. In agreement with this model, mutagenesis of Ser(H99) to alanine, or deletion of this residue, was found to reduce hysteresis by approximately 50%. (C) 2004 Elsevier Ltd. All rights reserved.

To confirm the assumption that 6-hydroxy-5,7-dimethyl-2-methylamino-4-(3-pyridylmethyl)benzothiazole (E3040) acts on urate reabsorption by inhibiting urate-anion exchange at the luminal membrane of renal tubules, we investigated the inhibitory effect of E3040 and its two conjugated metabolites on hydroxyl ion (OH-) gradient-dependent urate uptake into brush border membrane vesicles from rat renal cortex and compared it with other uricosuric agents. The order of potency was AA193 (5-chloro-7,8-dihydro-3-phenylfuro[2,3-g]-1,2-benzisoxazole-7-carboxylic acid)> benzbromarone > E3040 > probenecid > E3040 sulfate > E3040 glucuronide. Furthermore, kinetic analysis revealed that E3040 may be a competitive inhibitor of the OH- gradient-dependent uptake of urate into brush border membrane vesicles. (C) 2000 Elsevier Science B.V.

A tailor-made catalytically active polymer catalyzing the benzisoxazole isomerization is described. Kinetic studies carried out in water/ethanol (3:1, v/v) at room temperature, showed a rate acceleration (k(MIP)/k(control)) of 7.2-fold compared to the control polymer. The imprinted polymer exhibits Michaelis-Menten kinetics with a K-m of 0.484 mM and a k(cat) of 0.205 min(-1). Compared with the uncatalyzed reaction, a rate enhancement ((k(cat)/K-m)/k(uncat)) of 4 x 10(4) fold was obtained. Substrate selectivity, accessible binding site analysis, dissociation constant determination, and inhibition study were also performed.

In chemical reaction engineering, simulations are useful for investigating and optimizing a particular reaction process or system., Name: 2-Phenylbutanoic acid, Introducing a new discovery about 90-27-7, Name is 2-Phenylbutanoic acid, molecular formula is C10H12O2, belongs to benzisoxazole compound. In a document, author is Maximiano, Flavio A..

The rate of decarboxylation of 6-nitrobenzisoxazole-3-carboxylate, NBOC, was determined in micelles of N-hexadecyl-N,N,N-trimethylammonium bromide or chloride ( CTAB or CTAC), N-hexadecyl-N,N-dimethyl-3-ammonium-1-propanesulfonate (HPS), N-dodecyl-N,N-dimethyl-3-ammonium-1-propanesulfonate (DPS), N-dodecyl-N, N,N-trimethylammonium bromide (DTAB), hexadecylphosphocholine (HPC), and their mixtures. Quantitative analysis of the effect on micelles on the velocity of NBOC decarboxylation allowed the estimation of the rate constants in the micellar pseudophase, k(m), for the pure surfactants and their mixtures. The extent of micellar catalysis for NBOC decarboxylation, expressed as the ratio k(m)/k(w), where k(w) is the rate constant in water, varied from 240 for HPS to 62 for HPC. With HPS or DPS, k(m) decreased linearly with CTAB(C) mole fraction, suggesting ideal mixing. With HPC, k(m) increased to a maximum at a CTAB(C) mole fraction of ca. 0.5 and then decreased at higher CTAB(C). Addition of CTAB(C) to HPC, where the negative charge of the surfactant is close to the hydrophobic core, produces tight ion pairs at the interface and, consequently, decreases interfacial water contents. Interfacial dehydration at the surface in equimolar HPC/CTAB(C) mixtures, and interfacial solubilization site of the substrate, can explain the observed catalytic synergy, since the rate of NBOC decarboxylation increases markedly with the decrease in hydrogen bonding to the carboxylate group.
