, (2018/07/31)
In this paper, rGO/Pd–Fe3O4@PPy as an efficient stable nanocomposite was synthesized. To understand the synergetic effects of rGO, Pd, Fe3O4 and PolyPyrrole, the performance of rGO/Pd–Fe3O4@PPy as a heterogeneous recyclable nanocatalyst in the green synthesis of C-C and C-O coupling products, as well as different conditions are studied. Synthesized rGO/Pd–Fe3O4@PPy was characterized by FT-IR, XRD, FE-SEM, EDS, TGA and AFM analysis. Best results are obtained under sonication in H2O for C-C coupling and by ball-milling for C-O coupling. The benefits of this method include: green solvents and conditions, absence of external base, low reaction times with high yield and easy work-up method.

NOVEL INDOL CARBOXYLIC ACID BISPYRIDYL CARBOXAMIDE DERIVATIVES, PHARMACEUTICALLY ACCEPTABLE SALT THEREOF, PREPARATION METHOD AND COMPOSITION CONTAINING THE SAME AS AN ACTIVE INGREDIENT
-
Page/Page column 14, (2009/10/21)
Disclosed herein are a new indole carboxylic acid bispyridyl carboxamide derivative, a preparation method thereof, and a composition for prevention or treatment of obesity, urinary disorders, and CNS disorders, containing the same as an active ingredient. Because the indole carboxylic acid bispyridyl carboxamide derivatives according to the present invention have high affinity for 5-HT2c receptors, act selectively on the 5-HT2c receptors, the derivatives rarely have adverse effects caused by other receptors. Because the derivatives effectively inhibit serotonin activity, they may be useful for treatment or prevention of obesity; urinary disorders such as urinary incontinence, premature ejaculation, erectile dysfunction, and prostatic hyperplasia; CNS disorders such as depression, anxiety, concern, panic disorder, epilepsy, obsessive-compulsive disorder, migraine, sleep disorder, withdrawal from drug abuse, Alzheimer's disease, and schizophrenia, associated with 5-HT2c receptors.

Leukotriene B4 (LTB4) is a potent pro-inflammatory mediator that has been implicated in the pathogenesis of multiple diseases, including psoriasis, inflammatory bowel disease, multiple sclerosis and asthma. As a method to decrease the level of LTB4 and possibly identify novel treatments, inhibitors of the LTB4 biosynthetic enzyme, leukotriene A4 hydrolase (LTA4-h), have been explored. Here we describe the discovery of a potent inhibitor of LTA4-h, arylamide of glutamic acid 4f, starting from the corresponding glycinamide 2. Analogs of 4f are then described, focusing on compounds that are both active and stable in whole blood. This effort culminated in the identification of amino alcohol 12a and amino ester 6b which meet these criteria.

A novel series of 1H-indole-3-carboxylic acid pyridine-3-ylamides were synthesized and identified to show high affinity and selectivity for 5-HT2C receptor. Among them, 1H-indole-3-carboxylic acid[6-(2-chloro-pyridin-3-yloxy)-pyridin-3-yl]-amide (15k) exhibits the highest affinity (IC50 = 0.5 nM) with an excellent selectivity (>2000 times) over other serotonin (5-HT1A, 5-HT2A, and 5-HT6) and dopamine (D2-D4) receptors.
