ABSTRACT A series of 2-aminofluorenes N-alkylated with nitroxides or their precursors were synthesized. The new compounds were tested on hydroxyl radical and peroxyl radical scavenging ability and inflammatory assay on the endothelial brain cells. In agreement with ROS scavenging ability the same compound 7-bromo-N -[(1-Oxyl-2,2,6,6-tetramethyl-1,2,3,6-tetrahydropyridine-4yl)methyl]-9H-fluoren-2-amine (3b) and its hydroxylamine salt (3b/OH/HCl) showed the anti-inflammatory property on the endothelial brain cells.

    ABSTRACT: Proteins under stressful conditions can lead to the formation of an ordered self-assembled structure, referred to as amyloid fibrils, to which many neurodegenerative diseases such as Type II diabetes, Alzheimer's, Parkinson's, Huntington's, etc., are attributed. Inhibition of amyloid fibril formation using natural products is one of the main therapeutic strategies to prevent the progression of these diseases. Polyphenols are the mostly consumed as antioxidants in a human nutrition. Herein, we have studied the effect of a simple polyphenol, gallic acid (GA), one of the main components in plant tissues, especially in tea leaves, on the insulin amyloid fibril formation. Different biophysical characterizations such as turbidity, atomic force microscopy (AFM), Thioflavin T (ThT) assays, circular dichroism, and Fourier transform-infrared spectroscopy have been used to analyze the inhibition of amyloid fibril formation. The occurrence of fibrils in an AFM image and ThT fluorescence enhancement confirms the formation of insulin amyloid fibrils when incubated under acidic pH 2 at 65 �C. In the presence of GA, absence of fibrils in AFM image and no change in the intensity of ThT fluorescence confirms the inhibition of insulin amyloid fibrils by GA. Spectroscopic results reveal that GA inhibits the conformational transition of ahelix / b-sheet, which is generally induced during the insulin fibril formation. It was found that the inhibitory effect of GA is concentration dependent and non-linear. Based on the observed results, we propose that GA interacts with native insulin, preventing nuclei formation, which is essential for fibril growth, thereby inhibiting the amyloid fibril formation. The present results thus demonstrate that GA can effectively inhibit insulin amyloid fibril formation in vitro.

    ABSTRACT: Neurovascular inflammation is associated with a number of neurological diseases including vascular dementia and Alzheimer's disease, which are increasingly important causes of morbidity and mortality around the world. Lipotoxicity is a metabolic disorder that results from accumulation of lipids, particularly fatty acids, in non-adipose tissue leading to cellular dysfunction, lipid droplet formation, and cell death.
