| Description: | Binding affinity of the present compound for human 5-HT1A receptor, human 5-HT2A receptor, and human D2 receptor was measured by the following procedures.CHO cell membrane fraction in which human 5-HT1A receptor, human 5-HT2A receptor, and human D2 receptor were expressed was purchased from PerkinElmer, Inc. In a test for evaluating binding affinity, a test compound dissolved in dimethylsulfoxide (DMSO) and each receptor membrane sample diluted in buffer were mixed with [3H]8-OH-DPAT, [3H]Ketanserin, or [3H]Spiperone (all purchased from PerkinElmer, Inc.) for 5-HT1A receptor, 5-HT2A receptor, and D2 receptor, respectively. Each mixture was incubated at room temperature for 60 minutes. Then, the mixture was added quickly on a glassfiber filter plate (Multiscreen FB, Millipore, Inc.) coated with 0.3% aqueous polyethylenimine, and vacuum-filtered. Radioactivity remaining on the filter was measured with a liquid scintillation counter (PerkinElmer, Inc.). Binding inhibition rate was calculated from the following formula. |
