3H-(+/-)-4-Bromo-2,5-dimethoxyphenylisopropylamine (3H-DOB), a putative agonist radioligand, was synthesized and used to label 5-HT2 receptors in a particulate fraction prepared from rat frontal cortex tissue homogenates. The specific binding (defined by the difference in 3H-DOB binding in the presence and absence of 10(-6) M cinanserin, a potent and specific 5-HT2 antagonist) displayed high...
