- Amidoalkylindoles as Potent and Selective Cannabinoid Type 2 Receptor Agonists with in Vivo Efficacy in a Mouse Model of Multiple Sclerosis
-
Selective CB2 agonists represent an attractive therapeutic strategy for the treatment of a variety of diseases without psychiatric side effects mediated by the CB1 receptor. We carried out a rational optimization of a black market designer drug SDB-001 that led to the identification of potent and selective CB2 agonists. A 7-methoxy or 7-methylthio substitution at the 3-amidoalkylindoles resulted in potent CB2 antagonists (27 or 28, IC50 = 16-28 nM). Replacement of the amidoalkyls from 3-position to the 2-position of the indole ring dramatically increased the agonist selectivity on the CB2 over CB1 receptor. Particularly, compound 57 displayed a potent agonist activity on the CB2 receptor (EC50 = 114-142 nM) without observable agonist or antagonist activity on the CB1 receptor. Furthermore, 57 significantly alleviated the clinical symptoms and protected the murine central nervous system from immune damage in an experimental autoimmune encephalomyelitis (EAE) mouse model of multiple sclerosis.

- NOVEL INDOL CARBOXYLIC ACID BISPYRIDYL CARBOXAMIDE DERIVATIVES, PHARMACEUTICALLY ACCEPTABLE SALT THEREOF, PREPARATION METHOD AND COMPOSITION CONTAINING THE SAME AS AN ACTIVE INGREDIENT
-
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.

- Synthesis and structure-activity relationship of 1H-indole-3-carboxylic acid pyridine-3-ylamides: A novel series of 5-HT2C receptor antagonists
-
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.

- Design, synthesis, and biological activity of potent and selective inhibitors of mast cell tryptase
-
A new series of novel mast cell tryptase inhibitors is reported, which features the use of an indole structure as the hydrophobic substituent on a m-benzylaminepiperidine template. The best members of this series display good in vitro activity and excellent selectivity against other serine proteases.
