| Description: | Human 5-HT2A Receptor, Human 5-HT7 Receptor, and Human D2 Receptor: Binding affinity of the present compound for human 5-HT2A receptor, human 5-HT7 receptor, and human D2 receptor was measured by the following procedures.CHO cell membrane fraction in which human 5-HT2A receptor, human 5-HT7 receptor, or human D2 receptor was 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]Ketanserin, [3H]SB-269970, or [3H]Spiperone (all purchased from PerkinElmer, Inc.) for 5-HT2A receptor, 5-HT7 receptor, or D2 receptor, respectively. Each mixture was incubated at room temperature for 60 minutes. Non specific binding to receptors was obtained from a competitive binding test in the presence of 10 μmol/L 8-OH-DPAT, 10 μmol/L Mianserin, or 10 μmol/L Spiperone, respectively. Radioactivity caused by binding to receptors was measured with a liquid scintillation counter (PerkinElmer, Inc.), and 50% inhibition concentration was calculated. |
