Hapten design for antibody-catalyzed decarboxylation and ring-opening reactions of benzisoxazoles

Three benzisoxazole haptens designed to elicit antibody binding sites with widely differing polarity have been synthesized and used to induce antibodies in mice. Monoclonal antibodies were prepared using hybridoma technology, and screened for catalysis of the ring-opening isomerization and/or decarboxylation of a series of related benzisoxazoles and their 3-carboxy-derivatives. No catalysis of decarboxylation was observed, but 3 of a total of 47 antibodies obtained against the three haptens catalyzed the isomerization process. Of 12 antibodies raised against the 3-acetylbenzisoxazole structure 5 none was catalytically active; but one of 24 raised against a 3-isopropenylbenzisoxazole 6 increased the rate of ring-opening of 6-nitrobenzisoxazole, and 5 of 11 antibodies raised against a benzisoxazole 7 with a 3-amidinium group were moderately active against either 6-nitro or 6-acylaminobenzisoxazoles. Competitive binding studies suggest that at least some of the antibodies induced by the isopropenyl hapten do possess a recognizably hydrophobic binding site.

THE 1ST OPEN STUDY OF ZONISAMIDE, A NOVEL ANTICONVULSANT, SHOWS EFFICACY IN MANIA

1 Zonisamide, an anticonvulsant developed in Japan, is structurally similar to serotonin. Zonisamide has been proven to have a pharmacological profile that is very similar to that of carbamazepine. Thus, the effect of zonisamide was examined in 24 psychiatric patients: 15 with bipolar manic state, 6 with schizoaffective manic state, and 3 schizophrenic excitement. 2 Approximately 25% of all the patients and 33% of the bipolar manic patients showed remarkable global improvement with the addition of zonisamide. Approximately 71% of all the patients and 80% of the bipolar group had more than moderate global improvement. 3 No serious adverse reactions were found and no patients required zonisamide withdrawal. One patient developed both leukocytosis and mildly abnormal liver function test. One developed leukocytosis and another reported mild sleepiness. These reactions disappeared when zonisamide was discontinued.

Synthesis of novel 6-fluoro-3-(4-piperidinyl)-1,2-benzisoxazole derivatives as antiproliferative agents: A structure-activity relationship study

A series of novel 6-fluoro-3-(4-piperidinyl)-1,2-benzisoxazole derivatives 5(a-m) were synthesized with different substituted aromatic/heterocyclic acid chlorides (R-CO-Cl) and characterized by H-1 NMR, LC/MS, FTIR and elemental analyses. All the compounds synthesised were evaluated for their antiproliferative activity by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay. The antiproliferative effects of the synthesised compounds were tested against viable human skin fibroblast cells and carcinoma cells namely HeLa cells, HT-29 cells, MCF-7 cells, HepG-2 cells by adopting positive and negative control. The importance of the aromatic and heterocyclic moiety was confirmed. From the SAR studies, it reveals that, the substitution at N-terminal of 6-fluoro-3-(4-piperidinyl)-1,2-benzisoxazole by the heterocyclic ring plays a dominant role and was responsible for the antiproliferative activity. Among the synthesized compounds 5a, 5d and 5k have showed potent antiproliferative activity on all the carcinoma cells tested.

Effect of anti-inflammatory bowel disease drug, E3040, on urate transport in rat renal brush border membrane vesicles

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.

EXTRACTIVE SPECTROPHOTOMETRIC DETERMINATION OF QUETIAPINE FUMARATE IN PHARMACEUTICALS AND HUMAN URINE USING CALMAGITE AS AN ION-PAIR REAGENT

Quetiapine fumarate (QTF) is an antipsychotic drug belonging to the benzisoxazole derivatives indicated for the treatment of schizophrenia. A sensitive and selective method based on dichloromethane-extractable ion-pair of QTF with calmagite (CGT), which exhibited an absorption maximum at 490 nm, is described. At this. wavelength, Beer’s law is obeyed over the concentration range of 3.0-30.0 mu g ml(1). The apparent molar absorptivity, limit of detection (L OD) and quantitation (LOQ) values are 1.32×10(4) I mol(1) cm(-1), 0.27 and 0.81 mu g ml(1), respectively. The reaction is extremely rapid at room temperature and the absorbance values remain unchanged up to 19 h. The precision results, expressed as intra-day and inter-day relative standard deviation values, are satisfactory (RSD <= 2.2%). The accuracy is satisfactory as well (RE <= 2.44%). The method was successfully applied to the determination of QTF in pharmaceuticals and spiked human urine with satisfactory results. No interference was observed from common pharmaceutical adjuvants in tablets. Statistical comparison of the results with the official method showed an excellent agreement and indicated no significant difference in precision. Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.

REGIONAL DISTRIBUTION OF C-14 ZONISAMIDE IN RAT-BRAIN

Zonisamide (1,2-benzisoxazole-3-methane sulfonamide) is a new antiepileptic drug developed in Japan. This compound was proven to possess a strong inhibitory effect on convulsions of cortical origin, whether induced by electric or chemical stimuli, Regional distribution of C-14-zonisamide was investigated in rat brain using autoradiography. A high uptake of C-14 activity was observed in the cerebral cortex and the midbrain. A pair-match analysis of primary motor cortex versus primary sensory cortex revealed a slightly higher uptake in primary motor cortex. In the cerebellum, a higher uptake was observed in the cortex than medulla. Sagittal section analyses revealed that a high uptake of C-14 activity was observed in the cerebral cortex and colliculus, and a moderate uptake was seen in the cerebellum, thalamus, hypothalamus, and striatal body, thus suggesting the distribution of C-14-zonisamide is similar to that of flunitrazepam and phenytoin.

A mild procedure for the production of secondary amines from oximes and benzisoxazoles

-2-Hydroxybenzaldoximes are reduced under mild conditions of ammonium formate/Pd-C in methanol to give secondary amines. Benzisoxazoles react under the same mild conditions to give the same products. A possible mechanism is suggested, involving the intermediacy of the benzisoxazole in the oxime conversion. (C) 2003 Elsevier Ltd. All rights reserved.

Toward bifunctional antibody catalysis

Antibodies that catalyze the deprotonation of unactivated benzisoxazoles to give the corresponding salicylonitriles were prepared using as antigen a 2-aminobenzimidazolium derivative coupled to a carrier protein via its benzene ring. The hapten was designed to induce an antibody binding site with both a base and an acid, in position to initiate proton transfer and stabilize developing negative charge at the phenoxide leaving group, respectively. Consistent with this design, the catalysts exhibit bell-shaped pH-rate profiles, while chemical modification identified several functional groups that could participate in bifunctional catalysis. One of the antibodies, 13G5, is particularly notable in catalyzing the elimination of 6-glutaramidebenzisoxazole with a > 10(5)-fold rate acceleration over background and an effective molarity of > 10(4) M for its catalytic base. These properties compare favorably to the efficiencies achieved by the best previously characterized antibodies with substantially more reactive substrates. (c) 2006 Elsevier Ltd.
