The quantitative nucleophilic reactivity of alkyl and dialkylimidazo [1,2-a] pyridines towards methyl iodide is described. In the series of monomethyl derivatives the 7-methyl compound is the most activated and the 8-methyl compound the most deactivated. The effects of two alkyl substituants on the rate of alkylation are additive in the absence of intramolecular steric interaction. On the contrary a

The problem of the present invention is to provide a compound having a GR selective binding activity, which shows less action on other nuclear receptors such as progesterone receptor (PR), mineralocorticoid receptor (MR) and the like. The present invention provides a condensed tetrahydroquinoline compound represented by the following formula (I)
wherein each symbol is as defined in the present specification, or a pharmaceutically acceptable salt thereof or a hydrate thereof.
