Effect of vesicles of dimethyldioctadecylammonium chloride and phospholipids on the rate of decarboxylation of 6-nitrobenzisoxazole-3-carboxylate

Sonicated mixtures of dimethyldioctadecylammonium chloride (DODAC), egg phosphatidylcholine (PC), dimyristoyl phosphatidylcholine (DMPC), and dipalmitoyl phosphatidylcholine (DPPC) were used to analyze vesicle effects on the rate of decarboxylation of 6-nitrobenzisoxazol-3-carboxylic acid (Nboc). Electron microscopic images of the vesicles were obtained with trehalose, a know cryoprotector. Phase diagrams and phase transitions temperatures of the vesicle bilayers were determined. Nboc decarboxylation rates increased in the presence of vesicles prepared with both phospholipids and DODAC/phospholipid mixtures. Quantitative analysis of vesicular effects was done using pseudophase models. Phospholipids catalyzed up to 140-fold while the maximum catalysis by DODAC/lipid vesicles reached 800-fold. Acceleration depends on alkyl chain length, fatty acid insaturation of the lipids, and the DODAC/phospholipid molar ratio. Catalysis is not related to the liquid crystalline-gel state of the bilayer and may be related to the relative position of Nboc with respect to the interface.

A Divergent and Selective Synthesis of Isomeric Benzoxazoles from a Single N-Cl Imine

A divergent and regioselective synthesis of either 3-substituted benzisoxazoles or 2-substituted benzoxazoles from readily accessible ortho-hydroxyaryl N-H ketimines is described. The reaction proceeds in two distinct pathways through a common N-Cl imine Intermediate: (a) N-O bond formation to form benzisoxazole under anhydrous conditions and (b) NaOCl mediated Beckmann-type rearrangement to form benzoxazole, respectively. The reaction path also depends on the electronic nature of the aromatic ring, with the electron-rich aromatic rings favoring the rearrangement and the electron-deficient rings favoring the N-O bond formation. A Beckmann-type rearrangement mechanism via net [1,2]-aryl migration for the formation of 2-substituted benzoxazole is proposed.

Synthesis and binding affinities of a series of 1,2-benzisoxazole-3-carboxamides to dopamine and serotonin receptors

A series of 1,2-benzisoxazole-3-carboxamides derived from tertiary cycloalkylamines was synthesized and evaluated for affinity for serotonergic (5-HT3 and 5-HT4) and dopaminergic (D-2) receptors using radioligand binding assays. The majority of compounds displayed a very weak affinity for the studied neurotransmitter receptors. Only amides containing a conformationally rigid system retained a relative 5-HT3 receptor affinity. The presence of a quinuclidine group affected receptor interaction more favorably than the tropane framework.

EFFECT OF 1,2-BENZISOXAZOLE-3-ACETIC ACID ON PLANT-REGENERATION FROM PROTOPLASTS OF NICOTIANA-TABACUM

Benzisoxazole-3-acetic acid, a new synthetic growth regulator, was administered to protoplast cultures from Nicotiana tabacum and subsequently to the developed microcalluses, to test its activity on plant regeneration from protoplasts in different culture conditions. Such activity, compared to that of naphthalene-acetic acid, proved to be rather low in the stage of cellular division and microcallus formation but particulary high in the stage of shoot induction from microcallus, thus confirming that the activity of this compound is mainly morphogenetic.

Theoretical Insights into Ester-Directed Reactions between Propiolates with 1,2-Benzisoxazoles by Au(I) Catalyst: [4+2]-Annulation versus Michael-Type Products

Au(I)-catalyzed selective reactions of Et- and Bu-t-substituted propiolates (1a and 1a’) with 1,2-benzisoxazole(2a) provide a new strategy for purposefully access to desired bioactive heterocycles. Using DFT calculations, we have systematically investigated the detailed mechanisms and origins of the ester-controlled chemoselectivity. The calculated results indicated that both reactions are initiated by LAu+ pi-coordination, N nucleophilic attack, and NTf2–assisted stepwise H-shift, generating a nitrilium species identified as a common and requisite intermediate, which is significantly different from the experimentally proposed 6-alkoxy-1,3-oxazin-1-ium intermediate. Starting from the nitrilium intermediate, the newly established nucleophilic cyclization, alkene release, and NTf2–assisted stepwise protodeauration provides [4 + 2]-annulation product P-1, while the nitrilum dissociation, O nucleophilic attack, and NTf2–assisted stepwise protodeauration generates Michael-type product P-2. Further explorations showed that Bu-t-controlled chemoselectivity of P-1 over P-2 can be attributed to the energy favorable aromaticity of selective-determining nucleophilic cyclization TS. With substitution of Bu-t by Et group, the reversal of chemoselectivity to P-2 formation might be closely related to the presence of extremely unstable Et cation in ethylene release TS leading to P-1.

Synthesis of elastin based peptides conjugated to benzisoxazole as a new class of potent antimicrobials – A novel approach to enhance biocompatibility

The peptides of elastin sequences chosen for the present study included tetrapeptides, pentapeptides and tricosapeptides (30 amino acids), synthesized by classical solution phase method and conjugated to [3-(4-piperidyl)-6-fluoro-1,2-benzisoxazole]. The structures of the compounds were confirmed by physical and spectroscopic techniques followed by the antimicrobial evaluation by both agar well diffusion and microdilution methods. Here we wish to report the effect of conjugation of these moieties which enabled us to identify a novel set of peptides conjugated to heterocycle which have exhibited more potent antimicrobial activity than the conventional drugs used. Further, conjugates of tricosamers 34 and 35 were able to inhibit the growth of fungal species at 3-5 mu g/mL which is nearly 5 fold more potent than the reference drug. (C) 2010 Elsevier Masson SAS.

STUDIES ON URICOSURIC DIURETICS .5. CONVENIENT AND EFFICIENT SYNTHESIS OF 2,3-DIHYDROBENZOFURAN DERIVATIVES

A practical procedure for synthesis of a new uricosuric agent, 5-chloro-7,8-dihydro-3-phenylfuro[2,3-g]-1,2-benzisoxazole-7-carboxylic acid (1, AA-193) is described, which starts from 2,5-dichlorophenol (3b) and involves 5-chloro-6-hydroxy-3-phenyl-1,2-benzisoxazole (2) as the key intermediate. Successive treatment of 3b with benzoyl chloride-aluminum chloride (AlCl3) and hot ethanolic sodium hydroxide gives 4-benzoyl-2,5-dichlorophenol (8, 61%), which is oximated with hydroxylamine hydrochloride and then transformed into the benzisoxazole 2 (88%) with potassium hydroxide in N,N-dimethylformamide (DMF) (method C). The reaction of 2 with aqueous formaldehyde and dimethylamine affords the Mannich base Ila (97%), which is treated with a sulfonium ylide 12, 14 or 15 followed by heating with sodium hydroxide (NaOH) in ethanol (EtOH) to give 1 in high yield (method E).

Off-the-shelf proteins that rival tailor-made antibodies as catalysts

MIMICKING the efficiency of enzyme catalysis Is a daunting challenge, An enzyme selectively binds and stabilizes the transition state(s) for a particular reaction(1,2). Artificial host systems can bind ground states just as efficiently(3), and rate enhancements comparable to those in enzymatic reactions can be achieved by bringing catalytic and substrate groups together in intramolecular reactions, But the combination of selective binding and efficient catalysis remains elusive, The best enzyme mimics currently known are catalytic antibodies(5,6), They bind transition-state analogues with high affinity, but their catalytic efficiency generally falls far short of that of enzymes(4,8), Thorn et al.(9) recently described an antibody that catalyses the eliminative ring-opening of a benzisoxazole ”exceptionally efficiently” using carboxylate as the general base, raising the intriguing possibility that this high efficiency derives from precise positioning of catalytic and substrate groups(10). Here we show that familiar ‘off-the-shelf’ proteins-serum albumins-catalyse the same reaction at similar rates, using a lysine side-chain amino group as the catalytic general base, Comparisons suggest that formal general base catalysis is of only modest efficiency in both systems, and that the antibody catalysis Is boosted by a non-specific medium effect.
