DOES CHLORINATION MODIFY THE AUXIN-LIKE ACTIVITY OF 1,2-BENZISOXAZOLE-3-ACETIC ACID

The insertion of a chlorine atom in different positions of the aromatic ring did not increase the activity of benzisoxazole acetic acid, a new synthetic growth regulator, on shoot regeneration in vitro, pea stem elongation or flax root growth. This shows that this compound behaves differently from other synthetic auxins, and suggests that its activity is mainly related to the structure of its ring.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 526-83-0 is helpful to your research. Category: Benzisoxazole.

In silico docking studies and synthesis of new phosphoramidate derivatives of 6-fluoro-3-(piperidin-4-yl)benzo[d]isoxazole as potential antimicrobial agents

A new class of phosphoramidate derivatives of 6-fluoro-3-(piperidin-4-yl)benzo[d]isoxazole were synthesized in good to excellent yields (78-96%) by an in situ, three-step process. All the synthesized molecules were evaluated for anti-bacterial and anti-fungal activities using in vitro and in silico methods. The results revealed that the compounds 4b, 4d, 4h, 4i, and 4j exhibited the most promising anti-bacterial activity against S. aureus, B. subtilis, K. pneumoniae, S. typhi and P. mirabilis and anti-fungal activity against A. niger and A. flavus when compared with the standard drugs Norfloxacin and Nystatin at concentrations of 25, 50, 75 and 100 mu g/mL. The rest of the title compounds have shown moderate activity against all the bacterial and fungal strains. Molecular docking studies revealed that the synthesized compounds have exhibited significant binding modes with high dock scores ranging from -7.2 to -9.5 against 3V2B protein when compared with the standard drugs Norfloxacin (-5.8) and Nystatin (-6.6) respectively. Hence, it is suggested that the synthesized phosphoramidate derivatives of 6-fluoro-3-(piperidin-4-yl)benzo[d]isoxazole will stand as the promising antimicrobial drug candidates in future.

Determination of zonisamide by a coated monolithic column

In this paper, a monolithic ODS-silica gel column dynamically coated with cetylpyridinium chloride (CPC) was used to demonstrate the high-speed and efficient separation of zonisamide (1,2-benzisoxazole-3-methanesulfonamide, ZNS). its raw material (1,2-benzisoxazole-3-methanecarbonic acid) and intermediate (sodium 1,2-benzisoxazole-3-methanesulfonate) in drugs. Using a 40 mmol/L sodium perchlorate solution (pH 7.0) containing 10% acetonitrile as eluent, the analytes were eluted with a sharp and symmetrical peak within 3.0 min, detected with UV detection at 210 nm. The column demonstrates excellent stability over time, and exhibits unusual selectivity for pharmaceutical analysis. Thus, by this developed method, zonisamide in drug samples can be determined rapidly with high recoveries and good selectivity. (c) 2006 Elsevier B.V. All rights reserved.

1,2-benzisoxazole phosphorodiamidates as novel anticancer prodrugs requiring bioreductive activation

Several 1,2-benzisoxazole phosphorodiamidates have been designed as prodrugs of phosphoramide mustard requiring bioreductive activation. Enzymatic reduction of 1,2-benziosoxazole moiety is expected to result in the formation of imine intermediate due to the cleavage of the N-O bond. The imine should then be spontaneously hydrolyzed to a ketone metabolite, thereby facilitating base-catalyzed beta-elimination of cytotoxic phosphoramide mustard. As expected, the proposed prodrugs 4, 9, and 12 were at least 3-5-fold more potent cytotoxins than control compounds 5 and 15, which lack in the phosphoramide mustard group. Upon incubation with phenobarb-induced rat liver S-9 fraction, compounds 4, 9, and 12 underwent extensive NADPH-dependent metabolism with concomitant generation of alkylating activity under both hypoxic and oxic conditions. Corresponding ketone metabolites were detected for 9 and 15. NADPH-dependent bioreduction of 15 to its ketone metabolite 16 was located in the microsomal fraction and inhibited by SKF-525A and pCMBA. Compared with phenobarb-induced rat liver microsomal fraction, incubation of 15 with rat or human P450 reductase microsomes showed moderate generation of 16. Microsomal cytochrome P450 and/or P450 reductase appear to be involved in the reductive metabolism of 1,2-benzisoxazole moiety under hypoxic as well as oxic conditions.

Electric Literature of 40052-13-9, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 40052-13-9 is helpful to your research.

Synthesis and evaluation of 6-[C-11]methoxy-3-[2-[l-(phenylmethyl)-4-piperidinyl]ethyl]-1,2-benzisoxazole as an in vivo radioligand for acetylcholinesterase

6-Methoxy-3-[2-[1-(phenylmethyl)-4-piperidinyl]ethyl]-1,2-benzisoxazole is a high affinity (K-i = 8.2 nM) reversible inhibitor of acetylcholinesterase (AChE). The carbon-11 labeled form was prepared in high (>97%) radiochemical purity and with specific activities of 37 +/- 20 GBq/mu mol at end of synthesis, by the alkylation of the desmethyl precursor with [C-11]methyl trifluoromethanesulfonate in N,N dimethylformamide at room temperature. In vivo studies in mice demonstrated good blood brain permeability but essentially uniform regional brain distribution. Thus, despite in vitro and in vivo activity as an AChE inhibitor, 6-[C-11]methoxy-3-[2-[1-(phenylmethyl)-4-piperidinyl]ethyl]-1,2-benzisoxazole does not appear to be a good candidate for in vivo imaging studies of AChE in the mammalian brain.

APPLICATION OF HYPHENATED LC/NMR AND LC/MS TECHNIQUES IN RAPID IDENTIFICATION OF IN-VITRO AND IN-VIVO METABOLITES OF ILOPERIDONE

Iloperidone, 1-[4-[3-[4-(6-fluoro-1,2-benzisoxazol-3-yl]-1-piperidinyl]propoxy]-3-methoxyphenyl]ethanone, is currently undergoing clinical trials as a potential antipsychotic agent. Iloperidone was found to be extensively metabolized to a number of metabolites by rats, dogs, and humans, LC/MS/MS was used to characterize and identify metabolites of iloperidone present in complex biological mixtures obtained from all three species. Identification of some of the unknown metabolites in rat bile was achieved successfully by combination of LC/NMR and LC/MS with a minimum amount of sample cleanup. The utility of coupling a semipreparative HPLC to LC/MS instrument for further characterization of collected metabolites was demonstrated. It was shown that iloperidone was metabolized by O-dealkylation processes to yield 6-fluoro-3-[1-[3-hydroxypropyl)-4-piperidinyl]-1,2-benzisoxazole and 1-[4-[3-[4-(6-fluoro-1,2-benzisoxazol-3-yl)-1-piperidinyl]propoxy]-2-hydroxyphenyl]ethanone. Oxidative N-dealkylation led to the formation of 6-fluoro-3-(4-piperidinyl)-1,2-benzisoxazole and a secondary metabolite, 3-[(4-acetyl-2-methoxy)phenoxy]propionic acid. Iloperidone was reduced to produce 4-[3-[4-(6-fluoro-1,2-benzisoxazol-3-yl)-1-piperidinyl]propoxy]-3-methoxy-alpha-methylbenzenemethanol as the major metabolite in humans and rats. Hydroxylation of iloperidone produced 1-[4-[3-[4-(6-fluoro-1 ,2-benzisoxazol-3-yl)-1-piperidinyl]propoxy]-2-hydroxy-5-methoxyphenyl]ethanone and 1-[4-[3-[4-(6-fluoro-1,2-benzisoxazol-3-yl)-1 -piperidinyl]-3-methoxyphenyl]propoxy]-2-hydroxyethanone, the later of which was found to be the principal metabolite in dogs. The identities of all these metabolites were established by comparing the LC/MS retention times and mass spectral data with synthetic standards.

Cocrystals of zonisamide: physicochemical characterization and sustained release solid forms

We report four cocrystals of the antiepileptic drug, zonisamide (ZNS), which encounters half-life fluctuation when administered adjunctly with other antiepileptic drugs. Single crystals for two of the novel cocrystals of ZNS were successfully prepared from solvent evaporation experiments and their crystal structures were determined. Pharmaceutically acceptable cocrystals were analyzed for their dissolution rate, solubility and stability to draw conclusions on the impact of cocrystallization on the physicochemical properties of ZNS. It was found that the cocrystals showed lower solubility and dissolution rates and offer potential benefits in the development of sustained release formulations of ZNS which could address issues regarding its half-life fluctuation. Recent attempts to explore newer therapeutic applications have suggested ZNS as a potential drug for weight loss management. In this regard, the cocrystal of ZNS with caffeine, which has also been used in weight loss management, promises potential applications in the development of a novel fixed-dose combination drug which could offer synergistic therapeutic benefits in the treatment of obesity.
