| Description: | Determination of antagonistic activity of compounds of the general formula 1 towards 5-HT6 receptors. Compounds of the general formula 1 were tested for their ability to prevent 5-HT6 receptors activation by serotonin. HEK 293 cells (cells of human embryo's kidney) with artificially expressed 5-HT6 receptor, activation of which by serotonin leads to increasing the concentration of intracellular cAMP, were used. The level of intracellular cAMP was determined using reagent kit LANCE cAMP (PerkinElmer) according to the method described by the manufacturer of the kit [http://las.perkinelmer.com/content/Manuals/MAN_LANCEcAMP384KitUser.pdf]. Effectiveness of the compounds was estimated by their ability to reduce the level of intracellular cAMP induced by serotonin. Table 4 presents IC50 values for the compounds of general formula 1 in the setting of functional assay for serotonin 5-HT6 receptor inhibition. The data given testify their moderate or high antagonistic activity. |
