Synthesis and evaluation of novel 4-[(3H,3aH,6aH)-3-phenyl)-4,6-dioxo-2- phenyldihydro-2H-pyrrolo[3,4-d]isoxazol-5(3H,6H,6aH)-yl]benzoic acid derivatives as potent acetylcholinesterase inhibitors and anti-amnestic agents

The present study was designed to synthesize and evaluate pyrrolo-isoxazole benzoic acid derivatives as potential acetylcholinesterase (AChE) inhibitors for the management of Alzheimer’s disease. The synthesis of pyrrolo-isoxazole benzoic acid derivatives involved ring opening cyclization of p-aminobenzoic acid with maleic anhydride to yield maleanilic acid, which in turn afforded N-arylmaleimide via ring closed cyclization. Azomethine-N-oxides were obtained by condensation of N-arylhydroxylamine with differently substituted benzaldehydes followed by refluxing of N-arylmaleimide with differently substituted azomethine-N-oxides to pyrrolo-isoxazole benzoic acid derivatives as cis- and trans-stereoisomers. The synthesized compounds were evaluated in vitro for AChE inhibitory activity in rat brain homogenate with donepezil as standard AChE inhibitor. Thereafter, the most potent test compound was evaluated for in vitro butyrylcholinesterase inhibitory activity and in vivo memory evaluation in scopolamine (0.4 mg/kg)-induced amnesia in mice by employing Morris water maze test. All pyrrolo-isoxazole benzoic acid derivatives demonstrated potent AChE inhibitory activity. Most of compounds exhibited similar activity to donepezil and four of them (7h, 7i, 8i, and 8h, IC50 = 19.1 ¡À 1.9-17.5 ¡À 1.5 nM) displayed higher inhibitory activity as compared to donepezil (21.5 ¡À 3.2 nM) with compound 8ia (IC50 = 17.5 ¡À 1.5 nM) being the most active one. The test compound 8ia also ameliorated scopolamine-induced amnesia in mice in terms of restoration of time spent in target quadrant (TSTQ) and escape latency time (ELT). It may be concluded that pyrrolo-isoxazole benzoic acid derivatives may be employed as potential AChE inhibitors.

Synthesis, characterization and cytotoxicity appraisal of original 1, 2, 3-Triazole derivatives, against breast cancer cell lines (MDA-MB-231)

The present study established the efficient separate synthesis of four unique 1, 2, 3-triazole derivatives (M1, M2, M3, M4) via conducting 1,3-dipolar cycloaddition of N-((4-azidophenyl) sulfonyl) acetamide, with substituted N-phenylmaleimide. FTIR, 1H NMR, 13C NMR, and mass spectra were utilized for the characterization of the triazoles. The cytotoxic activities of these compounds, with regards to breast cancer cell lines (MDA-MB-231), were then evaluated. The cytotoxicity pre-screening outcomes for 100 muM portrayed a variety of actions, while the IC50 values with concentrations of 0-500 MuM for 48 hours, the results are 2.542, 2.929, 2.429, and 2.864 MuM for the compounds M1, M2, M3, and M4 respectively. Remarkably, the M2 and M4 para-substituted compounds exhibited superior IC50 values, in comparison to the M1 and M3 ortho-substituted compounds. This suggests that the M1 and M3 compounds have the potential to perform as against breast cancer.

Magnetic field-assisted alignment of graphene oxide nanosheets in a polymer matrix to enhance ionic conduction

This study aims to elucidate the effect of magnetic graphene oxide (GO) alignment in a polymer matrix on the ionic conduction and methanol barrier properties of the resulting composites. Magnetic iron oxide (Fe3O4) nanoparticles were fabricated and anchored on GO nanosheets. The magnetic GO-Fe3O4 nanofillers were incorporated into a quaternized polyvinyl alcohol (QPVA) matrix to form a polymeric composite. By applying a magnetic field (MF) along the in-plane direction during the drying and film formation steps, the GO-Fe3O4 nanosheets were aligned in an orientation parallel to the direction of the MF and connected to each other in elongated domains, as confirmed using transmission electron microscopy, field emission scanning electron microscopy/energy dispersive X-ray spectroscopy mapping, and laser scanning microscopy. The MF-aligned QPVA/GO-Fe3O4 electrolyte possessed higher conductivity and lower permeability than the un-aligned QPVA/GO-Fe3O4 membrane and pristine QPVA film. The aligned QPVA/GO-Fe3O4 composite exhibited a peak power density of 172.4 mW cm?2 at 60 C, which is higher than those of the composite without the MF treatment (67.7 mW cm?2) and the pristine QPVA (50.3 mW cm?2). This research demonstrates the extraordinary benefits of MF assisted GO-Fe3O4 nanofillers in facilitating the ion conduction and barrier property of a polymeric composite at 0.1% filler loading.

Graphene quantum dots decorated with maleimide and zinc tetramaleimido-phthalocyanine: Application in the design of ?OFF-ON? fluorescence sensors for biothiols

The fabrication of maleimide-derivatized graphene quantum dots (M-GQDs) and zinc phthalocyanine (2) as novel sensor probes for the selective detection of biothiols (cysteine, homocysteine or glutathione) through the rapid and specific Michael addition reaction between biothiols and the maleimide-derivatized probes is presented in this study. GQDs directly functionalized with maleimide units (M-GQDs) were synthesized and deployed for biothiols recognition following the principle of Michael addition. M-GQDs probe was found to be highly sensitive and selective towards biothiols detection in the nanomolar range in aqueous solution and at physiological pH (7.0). On the other hand, non-covalent interaction between pristine GQDs and novel zinc tetramaleimido-derivatized phthalocyanine resulted in the quenching of the pristine GQDs fluorescence emission which was switched back to the ?ON? mode by Michael addition mechanism in the presence of biothiols. Tested relevant biomolecules did not interfere in the quantitative recognition of the biothiols. The probes showed to be highly sensitive, specific and selective for biothiols sensing in simulated real samples.

Synthesis and characterisation of peripherally functionalised dendritic molecules

A number of peripherally functionalised dendritic molecules were synthesised in almost quantitative yield by a synthetic method involving the reaction between amines and isocyanates. The peripheral functional groups were incorporated by preparing a number of branched subunits, based on tris(hydroxymethyl)aminomethane (TRIS), 1, possessing three nitro, methoxy, methyl or maleimide terminal functionalities. Attachment of these branched units to the core molecules 4,4?-methylenebis(phenyl isocyanate) 13 and 1,3,5-benzene triisocyanate 20 afforded the corresponding dendritic molecules possessing 6 or 9 peripheral functional groups. Functional group conversions on the dendritic molecules have been successfully carried out, including hydrogenation of the terminal nitro to the corresponding amine and cleavage of the methoxy ether to give the corresponding phenol.
