Excited State Reactions of Oxazoles and Their Derivatives. Part I: Phototranspositions in the Ring

Heterocyclic compounds are a very important part of organic chemistry. Oxazole is a five-membered heterocycle with nitrogen and oxygen atoms in the ring. Oxazole is part of complex structures used in medicinal chemistry, pharmacology, and material chemistry. In the excited state, the oxazole ring can rearrange itself via several reaction mechanisms. In this paper, an extensive literature overview is given for photoisomerisations (phototranspositions) in oxazole, isoxazole, and benzisoxazole ring. A literature review is also given for phototransformations of the ring in the presence of oxygen (photooxygenation reactions), as well as for photoformation of the oxazole ring.

An efficient synthesis of a dual PPAR alpha/gamma agonist and the formation of a sterically congested alpha-aryloxyisobutyric acid via a Bargellini reaction

A practical synthesis of benzisoxazole 1 and its conversion to alpha-aryloxyisobutyric acid 2 using 1,1,1-trichloro-2-methyl-2-propanol (chloretone) was developed. Benzisoxazole I was formed in high yields by the action of either methanesulfonyl chloride/base upon intermediate oxime 8 or with thionyl chloride/base, which initially forms cyclic sulfite 10. A highly reactive, short-lived intermediate derived from chloretone was detected by ReacIR and its half-life determined to be similar to 5 min. Reaction conditions for the Bargellini reaction were developed that resulted in a 95% yield of 2 from the reaction of highly hindered phenol 1 with chloretone hemihydrate and powdered NaOH in acetone. Thus highly hindered alpha-aryloxyisobutyric acids can be made in a single step in high yield.

Zonisamide reduces nigrostriatal dopaminergic neurodegeneration in a mouse genetic model of Parkinson’s disease

Parkinson’s disease (PD) is a chronic neurodegenerative disorder characterized by the loss of nigrostriatal dopaminergic neurons and consequent motor dysfunction. Zonisamide (1,2-benzisoxazole-3-methanesulfonamide), which was originally developed as an antiepileptic drug, has been found to have therapeutic benefits for PD. However, the pharmacological mechanisms behind the beneficial actions of zonisamide in PD are not fully understood. Here, we investigated the neuroprotective effects of zonisamide on nigrostriatal dopaminergic neurons of the Engrailed mutant mouse, a genetic model of PD. Chronic administration of zonisamide in Engrailed mutant mice was shown to improve the survival of nigrostriatal dopaminergic neurons compared with that under saline treatment. In addition, dopaminergic terminals in the striatum and the motor function were improved in zonisamide-treated Engrailed mutant mice to the levels of those in control mice. To clarify the mechanism behind the neuroprotective effects of zonisamide, the contents of neurotrophic factors were determined after chronic administration of zonisamide. Brain-derived neurotrophic factor content was increased in the striatum and ventral midbrain of the zonisamide-treated mice compared to saline-treated mice. These findings imply that zonisamide reduces nigrostriatal dopaminergic cell death through brain-derived neurotrophic factor signaling and may have similar beneficial effects in human parkinsonian patients as well.

Design and synthesis of new of 3-(benzo[d]isoxazol-3-yl)-1-substituted pyrrolidine-2, 5-dione derivatives as anticonvulsants

A series of 3-(benzo[d]isoxazol-3-yl)-N-substituted pyrrolidine-2, 5-dione (7a-7d, 8a-8d, 9a-9c) have been prepared and evaluated for their anticonvulsant activities. Preliminary anticonvulsant activity was performed using maximal electroshock (MES) and subcutaneous pentylenetetrazole (scPTZ) tests after intraperitoneal (ip) injection into mice, which are the most widely employed models for early identification of anticonvulsant candidate. The acute neurological toxicity (NT) was determined applying rotorod test. The quantitative evaluation after oral administration in rats showed that the most active was 3-(benzo[d]isoxazol-3-yl)-1-(4-fluorophenyl) pyrrolidine-2, 5-dione (8a) with ED50 values of 14.90 mg/kg. Similarly the most potent in scPTZ was 3-(benzo[d]isoxazol-3-yl)-1-cyclohexylpyrrolidine-2, 5-dione (7d) with ED50 values of 42.30 mg/kg. These molecules were more potent and less neurotoxic than phenytoin and ethosuximide which were used as reference antiepileptic drugs. (c) 2014 Elsevier Masson SAS. All rights reserved.

Synthesis and anti-HIV activity of new alkenyldiarylmethane (ADAM) non-nucleoside reverse transcriptase inhibitors (NNRTIs) incorporating benzoxazolone and benzisoxazole rings

The HIV-1 non-nucleoside reverse transcriptase inhibitors (NNRTIs) constitute a large and structurally diverse set of compounds, several of which are currently used in the treatment of AIDS. A series of novel alkenyldiarylmethanes (ADAMs) were designed and synthesized as part of an ongoing investigation to replace the metabolically labile methyl ester moieties found in the ADAM pharmacophore with stable modifications that retain the potent anti-HIV activity of the parent compounds. Unsurprisingly, the rat plasma half-lives of the new ADAMs were not improved when compared to the parent compounds, but all of the synthesized ADAMs inhibited the cytopathic effect of HIV-1 in cell culture. The most potent compound identified was (E)-5-[1-(3,7-dimethyl-2oxo-2,3-dihydro-benzoxazol-5-yl)-5-methoxycarbonyl-pent-1-enyl]-2-methoxy-3-methylbenzoic acid methyl ester (7), which inhibited the cytopathic effects of both HIV-1(RF) and HIV-1(IIIB) strains in cell cultures with EC50 values of 30 and 90 nM, respectively, and inhibited HIV-1 reverse transcriptase with an IC50 of 20 nM.

Scaffold hopping for identification of novel D-2 antagonist based on 3D pharmacophore modelling of illoperidone analogs

The dopamine D-2 receptor is involved in the etiology of a number of disorders, such as Parkinson’s disease, Huntington’s Chorea, tardive dyskinesia and schizophrenia. Antagonism of D-2 receptors is implicated in the treatment of various psychiatric disorders. In order to understand essential structural features required for D-2 antagonism, this research article elaborates on the generation of a four-point 3D pharmacophore model which was extracted from a series of 45 novel 3-[[(aryloxy)alkyl]piperidinyl]-1,2-benzisoxazole derivatives. The best pharmacophore model generated consisted of four PRRR features: a positively charged group (P), and three aromatic rings (R). Based on the model generated, a statistically valid 3D-QSAR with good predictability (Q(2) = 0.756) was derived. For the validation of the pharmacophore hypothesis, active compounds were docked against the 3D structure of the D-2 receptor which was constructed through homology modeling. Further, the derived pharmacophore was used as a query to search the Zinc ‘clean drug-like’ database. Hits retrieved were passed progressively through filters, such as fitness score, predicted activity and docking scores. The resulting hits present new scaffolds with a strong potential for D-2 antagonist.

DEVELOPMENT OF POTENT SEROTONIN-3 (5-HT3) RECEPTOR ANTAGONISTS .2. STRUCTURE-ACTIVITY-RELATIONSHIPS OF N-(1-BENZYL-4-METHYLHEXAHYDRO-1H-1,4-DIAZEPIN-6-YL)CARBOXAMIDES

Our studies on 4-amino-5-chloro-2-ethoxybenzamides led to the discovery that the N-(1,4-dimethylhexahydro-1H-1,4-diazepin-6-yl)benzamide 9 and the 1-benzyl-4-methylhexahydro-1H-1,4-diazepine analogue 10 are potent serotonin-3 (5-HT3) receptor antagonists. Structure-activity relationship (SAR) studies on the influence of the aromatic nucleus of 9 and 10 upon inhibition of the von Bezold-Jarisch reflex in rats are described. Heteroaromatic rings such as pyrrole, thiophene, furan, pyridine, pyridazine, 1,2-benzisoxazole, indole, quinoline, and isoquinoline rings showed weak 5-HT, receptor antagonistic activity, Within this series, use of the 1H-indazole ring as an aromatic moiety led to a substantial increase of the activity; the 1H-indazolylcarboxamides 54, 57, 97, and 102 showed potent 5-HT3 receptor antagonistic activity. The optimal compound identified via extensive SAR studies was N-(1-benzyl-4-methylhexahydro-1H-1,4-diazepin-6-yl)-1H-indazole-3-carboxamide (54), whose effect was superior to that of the corresponding benzamide 10 and essentially equipotent to those of ondansetron (1) and granisetron (4).
