Modulation of imprinting efficiency in nanogels with catalytic activity in the Kemp elimination

The interactions between the template and the functional monomer are a key to the formation of cavities in the imprinted nanogels with high molecular recognition properties. Nanogels with enzyme-like activity for the Kemp elimination have been synthesized using 4-vinylpyridine as the functional monomer and indole as the template. The weak hydrogen bond interaction in the complex is shown to be able to induce very distinctive features in the cavities of the imprinted nanogels. The percentage of initiator used in the polymerisation, ranging from 1% to 3%, although it does not have a substantial effect on the catalytic rate, reduces considerably the imprinting efficiency. The alteration of the template/monomer ratio is also investigated, and the data show that there is considerable loss of imprinting efficiency. In terms of substrate selectivity, a number of experiments have been performed using 5-Cl-benzisoxazole as substrate analogue, as well as 5-nitro-indole as template analogue for the preparation of a different set of nanogels. All the kinetic data demonstrate that the chemical structure of the template is key to the molecular recognition properties of the imprinted nanogels that are closely tailored and able to differentiate among small structural changes.

HPLC method for simultaneous determination of impurities and degradation products in zonisamide

A gradient reversed phase HPLC method was developed and validated for the analysis of related substances in zonisamide (1,2-benzisoxazole-3-methanesulfonamide), using a Waters Symmetry C8 (150FNx013.9 mm) column with a flow rate of 1.0 ml/min and detection at 280 nm. The mobile phase component A consisted of a mixture of 0.02 M aqueous potassium dihydrogen phosphate-acetonitrile-methanol (75:10:15 v/v/v), pH adjusted to 4.0 with orthophosphoric acid. The mobile phase component B consisted of a mixture of 0.02 M aqueous potassium dihydrogen phosphate-acetonitrile-methanol (15:40:45 v/v/v), pH 2.0 with orthophosphoric acid. The limit of detection and limit of quantitation were in the range of 0.001-0.007 and 0.0035-0.25 respectively with respect to sample concentration of 2 mg/ml. The method was linear in the range of LOQ level to 200 of specified limits for II-VIII (< 0.10, r (2) = 0.9958-0.9999). The method is sensitive, specific, linear, accurate, precise and stability-indicating for the detection and quantitation of precursors (viz., 4-hydroxycoumarin, 1,2-benzisoxazole-3-acetic acid, 1,2-benzisoxazole-3-bromoacetic acid, 1,2-benzisoxazole-3-methylbromide, sodium 1,2-benzisoxazole-3-methanesulfonate), process impurities (viz., 2-hydroxyacetophenone oxime and 3,3,3-tribromomethyl-1,2-benzisoxazole) and drug degradation products formed under stress conditions. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

REGIONAL BRAIN DISTRIBUTION OF RISPERIDONE AND ITS ACTIVE METABOLITE 9-HYDROXY-RISPERIDONE IN THE RAT

Risperidone is a new benzisoxazole antipsychotic. 9-Hydroxy-risperidone is the major plasma metabolite of risperidone. The pharmacological properties of 9-hydroxy-risperidone were studied and appeared to be comparable to those of risperidone itself, both in respect of the profile of interactions with various neurotransmitters and its potency, activity, and onset and duration of action. The absorption, plasma levels and regional brain distribution of risperidone, metabolically formed 9-hydroxy-risperidone and total radioactivity were studied in the male Wistar rat after single subcutaneous administration of radiolabelled risperidone at 0.02 mg/kg. Concentrations were determined by HPLC separation, and off-line determination of the radioactivity with liquid scintillation counting. Risperidone was well absorbed. Maximum plasma concentrations were reached at 0.5-1 h after subcutaneous administration. Plasma concentrations of 9-hydroxy-risperidone were higher than those of risperidone from 2 h after dosing. In plasma, the apparent elimination half-life of risperidone was 1.0 h, and mean residence times were 1.5 h for risperidone and 2.5 h for its 9-hydroxy metabolite. Plasma levels of the radioactivity increased dose proportionally between 0.02 and 1.3 mg/kg. Risperidone was rapidly distributed to brain tissues. The elimination of the radioactivity from the frontal cortex and striatum-brain regions with high concentrations of 5-HT2 or dopamine-D-2 receptors-became more gradual with decreasing dose levels. After a subcutaneous dose of 0.02 mg/kg, the ED(50) for central 5-HT2 antagonism in male rats, half-lives in frontal cortex and striatum were 3-4 h for risperidone, whereas mean residence times were 4-6 h for risperidone and about 12 h for 9-hydroxy-risperidone. These half-lives and mean residence times were 3-5 times longer than in plasma and in cerebellum, a region with very low concentrations of 5-HT2 and D-2 receptors. Frontal cortex and striatum to plasma concentration ratios increased during the experiment. The distribution of 9-hydroxy-risperidone to the different brain regions, including frontal cortex and striatum, was more limited than that of risperidone itself. This indicated that 9-hydroxy-risperidone contributes to the in vivo activity of risperidone, but to a smaller extent than would be predicted from plasma levels. AUCs of both active compounds in frontal cortex and striatum were 10-18 times higher than those in cerebellum. No retention of metabolites other than 9-hydroxy-risperidone was observed in any of the brain regions investigated.

Molecular docking and simulation studies of 3-(1-chloropiperidin-4-yl)-6-fluoro benzisoxazole 2 against VP26 and VP28 proteins of white spot syndrome virus

White spot syndrome virus (WSSV), an aquatic virus infecting shrimps and other crustaceans, is widely distributed in Asian subcontinents including India. The infection has led to a serious economic loss in shrimp farming. The WSSV genome is approximately 300 kb and codes for several proteins mediating the infection. The envelope proteins VP26 and VP28 play a major role in infection process and also in the interaction with the host cells. A comprehensive study on the viral proteins leading to the development of safe and potent antiviral therapeutic is of adverse need. The novel synthesized compound 3-(1-chloropiperidin-4-yl)-6-fluoro benzisoxazole 2 is proved to have potent antiviral activity against WSSV. The compound antiviral activity is validated in freshwater crabs (Paratelphusa hydrodomous). An in silico molecular docking and simulation analysis of the envelope proteins VP26 and VP28 with the ligand 3-(1-chloropiperidin-4-yl)-6-fluoro benzisoxazole 2 are carried out. The docking analysis reveals that the polar amino acids in the pore region of the envelope proteins were involved in the ligand binding. The influence of the ligand binding on the proteins is validated by the molecular dynamics and simulation study. These in silico approaches together demonstrate the ligand’s efficiency in preventing the trimers from exhibiting their physiological function.

SYNTHESIS AND CATALYTIC PROPERTIES OF HYDROPHOBICALLY-MODIFIED POLY(ALKYLMETHYLDIALLYLAMMONIUM CHLORIDES)

Novel non-cross-linked and cross-linked, hydrophobically modified homo- and copolymers were synthesized by free-radical cyclo(co)polymerization of alkylmethyldiallylammonium chloride monomers in aqueous solution using ammonium persulfate as the initiator. Cross-linking was brought about by addition of a small amount of N,N’-methylenebisacrylamide. The cross-linked homo- and copolymers showed an increase of their reduced viscosity in aqueous solution upon the controlled introduction of cross-linking agent into their chemical structure. Viscosity measurements revealed that the conformational transition of polysoaps to compact coils in aqueous solution is strongly dependent upon the hydrophobic group content of the polysoaps. The formation of hydrophobic microdomains is akin to intramolecular micelle formation. Depending on the hydrophobic group content and the percentage of cross-linking, intermolecular aggregation was also revealed by viscosity measurements at higher concentrations of polysoap. The hydrophobic microdomains of the non-cross-linked and cross-linked polysoaps were characterized by hypsochromic shifts of the long-wavelength absorption band of Methyl Orange as a solvatochromic probe, non-covalently bound to the macromolecule. Catalysis of the unimolecular decarboxylation of 6-nitrobenzisoxazole-3-carboxylate by the non-cross-linked and crosslinked copolymers was investigated in aqueous solution at pH 11.3 and 30 degrees C. The cross-linked polysoaps exhibited higher catalytic activities for decarboxylation than the corresponding non-cross-linked analogues. A maximum in rate constant was found at about 0.2% (w/w) of cross-linking agent in the cross-linked polysoaps. The decarboxylation rate is strongly dependent upon the hydrophobic group content in the polysoaps.

A convenient method for the preparation of 2-aminobenzophenone derivatives under ultrasonic irradiation

A quick and convenient method for the preparation of 2-aminobenzophenone derivatives is described. This approach consists of the nucleophilic substitution reaction of nitrobenzenes by phenylacetonitrile under conventional and ultrasonic conditions followed by reduction of the produced 2,1-benzisoxazole to 2-aminobenzophenone. This 2-step reaction was studied by changing the reaction parameters (reaction temperature, ultrasound power, and reaction time). The results clearly demonstrated that using ultrasound irradiation results in a high yield within a short reaction time.
