The design of biocatalysts is a goal to improve the rate, selectivity, and environmental friendliness of chemical processes in biotechnology. In this regard, the use of computational techniques has provided valuable assistance in the design of enzymes with remarkable catalytic activity. In this paper, hybrid QM/MM simulations have allowed getting an insight into the mechanism of a promiscuous aldoxime dehydratase (OxdA) for Kemp elimination. We first demonstrate that, based on the use of linear response approximation (LRA) methods, the lowest energy electronic state of the benzisoxazole placed in the active site of OxdA corresponds to a singlet state, the triplet and the quintet states being higher in energy. The presence of a heme group at the active site of the OxdA promiscuous enzyme opens the possibility of exploring a redox mechanism, similar to the one proposed in other reactions catalyzed by heme-dependent enzymes. In addition, according to the geometrical analysis of the active site of this aldoxime dehydratase, the presence of a good base in the active site, His320, the proper pose of the substrate assisted by the porphyrin, and an adequate electrostatic environment to stabilize the negative charge developed in the oxygen-leaving group makes available an acid/base mechanism. Comparison of the results derived from the exploration of both acid/base and redox mechanisms at the B3LYP(Def2-TZVP)/MM level shows how the latter renders the most favorable reaction path within the quintet state. The obtained activation free energy is in good agreement with the activation energy that can be deduced from the experimentally measured rate constant.

Zonisamide is a benzisoxazole-based compound first synthesized in the early 1970s by the research laboratories of Dainippon Pharmaceutical Company in Osaka, Japan. Identified as an anticonvulsant during exploratory research, zonisamide has since been characterized as having broad-spectrum antiepitepsy and neuroprotective effects. Early clinical studies in Japan demonstrated that zonisamide has a long elimination half-life and is well tolerated; Phase II and III clinical trials established the drug’s efficacy and safety for the treatment of partial and generalized seizures. In 1989, zonisamide was approved and marketed in Japan under the trade name of Excegran(R). Data from postmarketing surveillance studies and clinical observations over 10 years of use have continued to support zonisamide’s efficacy and safety, identified its usefulness as monotherapy, and characterized its effectiveness for various seizure types and epilepsy syndromes.

The stability of two benzisoxazole antipsychotics was determined in vitro in decomposing porcine blood inoculated with bacteria, utilizing a high-performance liquid chromatography with ultraviolet and fluorescence detection method for drug quantitation. Stability experiments for risperidone and paliperidone were conducted at 7, 20 and 37 degrees C for 4 days using sterile and bacterially inoculated porcine blood. The drugs were stable in sterile blood at each temperature and in inoculated blood at 7 degrees C, but degraded significantly in inoculated blood at 20 and 37 degrees C. Complete loss occurred within 2 days when incubated at 37 degrees C. The benzisoxazole-cleaved degradation products for both drugs were identified as 2-hydroxybenzoyl-risperidone and 2-hydroxybenzoyl-paliperidone utilizing liquid chromatography quadrupole-time-of-flight mass spectrometry and accurate mass measurements. The degradation products have been found in postmortem case studies, including one case where risperidone and paliperidone were not detected, indicating complete conversion can occur in situ.

A series of 3-(2-thienyl)- and 3-(1-imidazolyl)-1,2-benzisoxazoles as well as some isomeric benzoxazoles were synthesized and tested in vitro for their inhibitory effect on arachidonic acid-induced human platelet aggregation. The most active compound (7-methoxy-3-(2-thienyl)-1,2-benzisoxazole 5c) was nearly 20-30-fold more potent than acetylsalicylic acid in inhibiting platelet aggregation. Structure-activity relationships within the series are briefly discussed.

Metabolism of a Serotonin-4 Receptor Partial Agonist 4-{4-[4-Tetrahydrofuran-3-yloxy)-Benzo[d]Isoxazol-3-yloxymethyl]-Piperidin-1-ylmethyl}-Tetrahydropyran-4-ol (TBPT): Identification of an Unusual Pharmacologically Active Cyclized Oxazolidine Metabolite in Human

4-{4-[4-Tetrahydrofuran-3-yloxy)-benzo[d]isoxazol-3-yloxymethyl]-piperidin-1-ylmethyl}-tetrahydropyran-4-ol (PF-4995274, TBPT) is a new agent that is a partial agonist of the human serotonin-4 (5-HT4) receptor and is under investigation for neurological disorders. Metabolism of TBPT was examined in vitro in human liver microsomes and human hepatocytes. Metabolites were also identified in the plasma of healthy human subjects in a phase 1 clinical study. Human-derived metabolite profiles were compared with corresponding profiles obtained in laboratory animal species. There were two major routes of metabolism in vitro: N-dealkylation of the methyltetrahydropyran moiety (M1) and hydroxylation at the seven position of the benzisoxazole moiety (M4). These were also observed in human plasma; however, in that matrix, the major metabolite was an unusual cyclized oxazolidine entity (M2). M2 was proposed to be formed via generation of an intermediate 4. iminium ion on the piperidine ring followed by spontaneous cyclization by attack of the beta-hydroxyl substituent of the tetrahydropyran ring to form a cyclized oxazolidine product. An authentic standard of the metabolite was generated using a methylene-blue-sensitized photochemical oxidation reaction as well as microbial transformation. Further investigation of this metabolite showed that it also possessed 5-HT4 agonism activity similar to the parent. The metabolite was 150-fold more highly protein bound in human plasma than TBPT, which is consistent with its presence as a major circulating metabolite while being only a minor metabolite in in vitro systems. Overall, this illustrates the importance of understanding the complex dispositional properties of a pharmacologically active metabolite. (C) 2013 Wiley Periodicals, Inc.

A synthetic route to novel 3-substituted-2,1-benzisoxazoles from 5-(2-nitrobenzylidene)(thio)barbiturates

2,1-Benzisoxazoles, also called anthranils, are one of the two types of aromatic bicyclic heterocycles having a benzene ring fused with an isoxazole, which are particularly recognized as valuable intermediates in organic synthesis. Nevertheless several methods can be found in the literature to prepare 2,1-benzisoxazoles, we herein report a new, efficient, simple, mild, and alternative procedure to prepare 3-substituted-2,1-benzisoxazoles from 5-(2-nitrobenzylidene)barbiturates in moderate to good yields (51-82%). All the novel benzisoxazoles showed spectral data fully consistent with the assigned structures, which were unequivocally confirmed by single crystal X-ray analysis. A possible mechanism of the reaction is proposed. In addition, a screening of the bioactivity of these benzisoxazoles as xanthine oxidase inhibitors, antioxidants, and cytotoxic compounds was performed. The benzisoxazole formed from barbituric acid revealed moderate xanthine oxidase inhibitory effects (IC50 = 22.10 mu M). (C) 2017 Academie des sciences. Published by Elsevier Masson SAS.
