Sigma-2 receptor radiotracers for imaging the proliferative status of solid tumors

摘要

Novel benzamide compounds of Formula (I), Formula (II) and Formula (III, salts, water soluble salts, analogs and radiolabeled counterparts thereof as sigma-2 receptor radiotracers for imaging the proliferative status of solid tumors. A method for diagnosing a mammal for the presence of a mammalian tumor therein comprises administering to the mammal a diagnostic imaging detectable effective amount of a benzamide compound having a structure illustrated in Formula (I), Formula (II) and Formula (III) and detecting binding of the compound to a tumor in the mammal. A method for diagnostic imaging of a mammalian tissue having cell surface sigma-2 receptors comprising administering to a mammal a diagnostic imaging amount of a compound having a structure illustrated in Formula (I) Formula (II) and Formula (III) and detecting an image of a tissue having an ample cells with sigma-2 receptors.
