Synthesis and Screening of Pro-apoptotic and Angio-inhibitory Activity of Novel Benzisoxazole Derivatives both In Vitro and In Vivo

Background: Triple Negative Breast Cancer (TNBC) tends to be more aggressive than other types of breast cancer. Resistance to chemotherapy is a major obstacle hence there is a significant need for new antineoplastic drugs with multi-target potency. Numerous Benzoisoxazole moieties have been found to possess a broad spectrum of pharmacological activities. In the present study, we have synthesized 9 novel derivatives of Benzisoxazole 7(a-i) and screened them for their biological potential. Methods: Chemical synthesis, Mass spectrometry (HRMS), cell proliferation and cytotoxicity assay, wound healing assay, flow cytometry and nuclear staining. Angio-inhibitory activity assessed by corneal micropocket assay and in vivo peritoneal angiogenesis assay. Results: The Benzisoxazole derivatives 7(a-i) were synthesized and screened for their biological potency by both in vitro and in vivo experimental models. Among the series, compound 3-(1-((3-(3(Benzyloxy)-4-methoxyphenyl)4,5-dihydroisoxazole-5-yl) methyl)piperidine-4-yl)6-fluorobenzo[d] isoxazole (7e) was found to be most promising, with an average IC50 value of 50.36 +/- 1.7 mu M in MTT assay and showed 81.3% cell death. The compound 7e also showed 60-70% inhibition on a recombinant Metastasis-Associated protein (MTA1) induced proliferation and cell migration in MDAMB-231 cells, which is known to play a major role in angiogenesis. The anti-tumour studies inferred the regression of tumour activity. This was due to inhibition of neovascularization and evoking apoptosis process as assessed by corneal vascularization, peritoneal angiogenesis and apoptotic hallmarks in 7e treated cells. Conclusion: These findings not only show the biological efficacy of compound 7e but it is also an effective beginning to explore the mechanism of metastasis and cancer therapy strategy targeting MTA1. The observed biological activity makes compound 7e an attractive drug candidate.

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.

Iloperidone: a new benzisoxazole atypical antipsychotic drug. Is it novel enough to impact the crowded atypical antipsychotic market?

Iloperidone is a new-generation atypical antipsychotic agent, acting as a serotonin/dopamine (5-HT2A/D-2) antagonist, under development by Vanda Pharmaceuticals for the treatment of schizophrenia, bipolar disorder and other psychiatric conditions. Chemically, iloperidone is a benzisoxazole, like risperidone, and shows a multiple receptor binding profile, sharing this feature with the other atypical antipsychotic agents. Administered orally, the drug is highly bound to plasma proteins and extensively metabolised. Several clinical trials have been carried out, to check efficacy, safety and side effects. in order to introduce iloperidone as an agent for the treatment of schizophrenia, a short overview of the disease and of the most important antipsychotic drugs available or under development will be reported. Iloperidone pharmacokinetics and pharmacodynamics are presented herein, together with an evaluation of clinical safety and efficacy results.

Optimization and In Vivo Toxicity Evaluation of G4.5 Pamam Dendrimer-Risperidone Complexes

Risperidone is an approved antipsychotic drug belonging to the chemical class of benzisoxazole. This drug has low solubility in aqueous medium and poor bioavailability due to extensive first-pass metabolism and high protein binding (>90%). Since new strategies to improve efficient treatments are needed, we studied the efficiency of anionic G4.5 PAMAM dendrimers as nanocarriers for this therapeutic drug. To this end, we explored dendrimer-risperidone complexation dependence on solvent concentration, pH and molar relationship. The best dendrimer-risperidone incorporation (46 risperidone molecules per dendrimer) was achieved with a mixture of chloroform: methanol 50:50 v/v solution pH 3. In addition, to explore the possible effects of this complex, in vivo studies were carried out in the zebrafish model. Changes in the development of dopaminergic neurons and motoneurons were studied using tyrosine hydroxylase and calretinin, respectively. Physiological changes were studied through histological sections stained with hematoxylin-eosin to observe possible morphological brain changes. The most significant changes were observed when larvae were treated with free risperidone, and no changes were observed when larvae were treated with the complex.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 99189-60-3. The above is the message from the blog manager. Formula: C10H17NO3.

Mechanism and Origins of Product Selectivity of Au-Catalyzed Coupling Benzisoxazoles with Ynamides: A Computational Study

Au(I)-catalyzed coupling of benzisoxazoles and ynamides was recently reported to synthesize challenging indoloquinoline core structures. In this report, we employed DFT methods to elucidate the mechanistic details of this reaction. The results reveal that the catalytic cycle involves initial coupling of ynamide with benzisoxazole, simultaneous ring opening of the isoxazole unit and attack of the dimethoxybenzene (DMOB) unit to gold carbenoid, proton transfer from the DMOB group to hydroxyl group, thioether migration, ring closure, and proton transfer. The experimentally observed ligand-controlled product selectivity is reproduced well by the calculations. The product selectivity-determining step is the ring opening of the isoxazole unit. The flexible P(t-Bu)(2)(o-biphenyl) ligand facilitates the approach of the DMOB group to gold carbenoid, which brings about significant C-H/pi interactions in the transition state for ring opening, and thus leads to the indoloquinoline product. The rigid 1,3-bis(diisopropylphenyl)imidazol-2-ylidene ligand prefers keeping the DMOB group away from the gold carbenoid, which can cause strong orbital interaction in the transition state for ring opening, and thus results in indole product.

Enantioselective Synthesis of beta-Amino Acid Derivatives Enabled by Ligand-Controlled Reversal of Hydrocupration Regiochemistry

A Cu-catalyzed enantioselective hydroamination of alpha,beta-unsaturated carbonyl compounds for the synthesis of beta-amino acid derivatives was achieved through ligand-controlled reversal of the hydrocupration regioselectivity. While the hydrocupration of alpha,beta-unsaturated carbonyl compounds to form alpha-cuprated species has been extensively investigated, we report herein that, in the presence of an appropriate ancillary chiral ligand, the opposite regiochemistry can be observed for cinnamic acid derivatives, leading to the delivery of the copper to the beta-position. This copper can react with an electrophilic aminating reagent, 1,2-benzisoxazole, to provide enantioenriched beta-amino acid derivatives, which are important building blocks for the synthesis of natural products and bioactive small molecules.

Biocatalysis of isomerization of 1,2-benzisoxazole by bovine serum albumin in an organic solvent

The catalytic properties of bovine serum albumin (BSA) have been studied rather extensively. The protein has shown catalytic activities toward a variety of reactions in aqueous media. However, there appears to be no reports of reactions catalyzed exclusively in organic media. In this study, we report the catalytic property of BSA on the isomerization of 1,2-benzisoxazole in an organic solvent. Kinetics were performed using a continuous flow system in a spectrophotometer at 330 rim. The catalysis showed a Michaells-Menten behavior with an estimated catalytic, efficiency (k(cat)/K-M) of 8.77 M-1S-1. The influence of water content and inhibitors was also studied. The activity of BSA in acetonitrile is approximately 20% of that in water under similar conditions. Inhibition studies show that the active site may be the pyridoxal binding site involving Lys-220.

Design, synthesis and evaluation of bicyclic benzamides as novel 5-HT1F receptor agonists

Several fused bicyclic systems have been investigated to serve as the core structure of potent and selective 5-HT1F receptor agonists. Replacement of the indole nucleus in 2 with indazole and ‘inverted’ indazole provided more potent and selective 5-HT1F receptor ligands. Indoline and 1,2-benzisoxazole systems also provided potent 5-HT1F receptor agonists, and the 5-HT1A receptor selectivity of the indoline- and 1,2-benzisoxazole-based 5-HT1F receptor agonists could be improved with modification of the benzoyl moiety of the benzamides. Through these studies, we found that the inherent geometries of the templates, not the nature of hybridization of the linking atom, were important for the 5-HT1F receptor recognition.
