SB-206553 is a drug which acts as a mixed antagonist for the 5-HT2B and 5-HT2C serotonin receptors.[1][2][3] It has anxiolytic properties in animal studies and interacts with a range of other drugs.[4][5][6][7][8][9][10][11][12] It has also been shown to act as a positive allosteric modulator of α7 nicotinic acetylcholine receptors.[13]
