Discovery of imidazo[1,2-a]pyridines as potent MCH1R antagonists
摘要:
A series of imidazo[1,2-a] pyridine derivatives was identified and evaluated for MCH1R binding and antagonistic activity. Introduction of a methyl substituent at the 3-position of imidazo[1,2-a] pyridine provided compounds with a significant improvement in MCH1R affinity. Representative compounds in this series exhibited good potency and brain exposure in rats. (C) 2009 Elsevier Ltd. All rights reserved.

The present invention discloses novel compounds of Formula (I) or pharmaceutically acceptable salts thereof, which have histamine-H3 receptor antagonist or inverse agonist activity, as well as methods for preparing such compounds. In another embodiment, the invention discloses pharmaceutical compositions comprising compounds of Formula (I) as well as methods of using them to treat obesity, cognitive deficiencies, narcolepsy, and other histamine H3 receptor-related diseases
The invention provides imidazopyridine derivatives represented by the general formula [I] [in which R
1
and R
2
may be the same or different and stand for C
1-6
alkyl or the like, R
3
and R
4
stand for hydrogen atom, methyl group or the like, W stands for mono- or bi-cyclic 3- to 8-membered aromatic or aliphatic heterocycle or the like, and Ar stands for optionally substituted aromatic heterocycle or the like]. These compounds act as melanin-concentrating hormone receptor antagonist and are useful as medicines for central nervous system disorders, cardiovascular system disorders and metabolic disorders.
