Objectives Alzheimer’s disease (AD) is characterized by reduced acetylcholinesterase (AChE) activity in the postmortem tissues of AD patients. Therefore, AChE has been an attractive target for the diagnosis of AD. In the present study, 5,7-dihydro-3-[2-(1-(phenyimethyl)-4piperidinyl)ethyl]-6H-pyrrolo[3,2-f]-1,2-benzisoxazol-6-one (CP-118,954), a potent AChE inhibitor, was labelled with radiolodine and evaluated as an AChE imaging agent for SPECT. Methods Radioiodine-labelled CP-118,954 was prepared from CP-144,885 and [I-125]iodobenzyl bromide, and anti-AChE activities of iodine-substituted CP-118,954 were measured. Metabolism studies were carried out in samples of blood and whole brain of mice injected with 2[I-123]iodo-CP-118,954 (I-123-1). Tissue distribution studies were also performed in mice injected with I-125-1, and samples of blood, thyroid, stomach, and brain tissue (cerebellum, striatum and cortex) were removed, weighed and counted. Results Of the ligands, 2-iodo-CP-118,954 exhibited higher binding affinity for AChE (IC50 = 24 nM) than the other positional isomers. 2-[I-125]lodo-CP-118,954 was found to have a lipophilicity (log P=2.1) favouring brain permeability and metabolic stability in mouse brain, but a marginal target (striatum) to non-target (cerebellum) uptake ratio (1.1) in mouse brain. Conclusion This result demonstrates that 2-[I-125]iodo-CP-118,954 may be unsuitable for AChE imaging. These findings suggest that radioligands suitable for AChE imaging should have not only a specific structure but also a sub-nanomolar to low nanomolar IC50.

Zonisamide, a benzisoxazole derivative, is an antiepileptic drug with a long half-life. Three nationwide, double-blind, placebo-controlled studies carried out in Japan prompted the approval of zonisamide as an antiparkinsonian agent in early 2009. The addition of zonisamide at 25-50 mg/day to currently used antiparkinsonian drugs significantly improved cardinal symptoms in patients with advanced Parkinson’s disease. The effects were maintained over more than 1 year even in patients with advanced disease. Zonisamide has multiple modes of action, and its effects on Parkinson’s disease include activation of dopamine synthesis, inhibition of monoamine oxidase, inhibition of T-type calcium channels and inhibition of an indirect pathway in the basal ganglia through the delta opioid receptor Furthermore, zonisamide exhibits neuroprotective effects in animal models of Parkinson’s disease. It strongly inhibits quinoprotein formation and markedly increases glutathione S-transferase levels in the striatum by enhancing the astroglial cysteine transport system and/or astroglial proliferation via S100 beta production and secretion.

Catalytic Asymmetric Hydrogenation of 3-Substituted Benzisoxazoles

A variety of 3-substituted benzisoxazoles were reduced with hydrogen using the chiral ruthenium catalyst, {RuCl(p-cymene)[(R,R)-(S,S)-PhTRAP]}Cl. The ruthenium-catalyzed hydrogenation proceeded in high yield in the presence of an acylating agent, affording alpha-substituted o-hydroxybenzylamines with up to 57% ee. In the catalytic transformation, the N-O bond of the benzisoxazole substrate is reductively cleaved by the ruthenium complex under the hydrogenation conditions. The C-N double bond of the resulting imine is saturated stereoselectively through the PhTRAP-ruthenium catalysis. The hydrogenation produces chiral primary amines, which may work as catalytic poisons, however, the amino group of the hydrogenation product is rapidly acylated when the reaction is conducted in the presence of an appropriate acylating agent, such as Boc(2)O or Cbz-OSu.

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.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 557-59-5, you can contact me at any time and look forward to more communication. Safety of Tetracosanoic acid.

Non-cross-linked and cross-linked poly(alkylmethyldiallylammoniumhalides): synthesis and aggregation behavior

Hydrophobically modified polyelectrolytes (polysoaps) are a unique class of water-soluble polymers containing distinct hydrophobic and hydrophilic regions. Above a certain concentration, polysoaps form intramolecular and intermolecular aggregates in aqueous solution. They have attracted much attention not only for their ability to mimic some functions demonstrated by biopolymers but also for their important industrial applications. This review highlights some interesting features of novel non-cross-linked and cross-linked poly(alkylmethyldiallyl-ammonium halides) that have been described in recent years.

REDUCTIVE METABOLISM OF THE ANTICONVULSANT AGENT ZONISAMIDE, A 1,2-BENZISOXAZOLE DERIVATIVE

1. The metabolism of zonisamide in vitro was characterized through aerobic and anaerobic incubations with rat liver subcellular fractions and cultured gastrointestinal microflora. 2. Zonisamide reacted with rat hepatic microsomal cytochrome P-450 and exhibited a Type I binding spectrum. 3. Metabolism of zonisamide in vitro by hepatic subcellular fractions and cultured gastrointestinal flora produced a single metabolite, 2-(sulphamoylacetyl)-phenol (2-SMAP), by reductive cleavage of the 1,2-benzisoxazole ring. 4. The reductive metabolism of zonisamide was primarily mediated by microsomal cytochrome P-450. The soluble fraction enhanced reduction when combined with the microsomal fraction but itself possessed only weak reductive activity. 5. Reduction of zonisamide by the most enzymically active liver fractions required NADPH, was stimulated by FMN and SKF-525A, and was inhibited by CO or air, as well as by n-octylamine. 6. Unlike their involvement in the reduction of numerous nitro, azo, and N-oxide compounds, cultured aerobic and anaerobic intestinal flora were not principally involved in the reduction of zonisamide.
