[11C]-SCH-442416 was designed and synthesized by scientists at the University of Milano-Bicocca with the intent of development as a PET imaging probe. [11C]-SCH-442416 demonstrates a selective high affinity as an antagonist of the A2A Adenosine Receptor with a Ki of 0.48 nM. [11C]-SCH-442416 has demonstrated the ability to cross the blood-brain barrier and has been used as an imaging agent in a number of animals studies and at least one clinical trial in healthy human volunteers. It should be noted that the non-radio labeled form of SCH-442416 has been investigated in rats for the treatment of addictive behaviors.

Sample Use Guides

In a phase 1 clinical trial 370 MBq of [11C]-SCH442416 was administered to healthy volunteers intravenously as a bolus injection over 30 seconds following the start of each PET scan. The diagnostic objective is to monitor the extent to which another compound (BIIB014) will occupy the brain's A2A receptors after 8 to 12 days of dosing.
Route of Administration: Intravenous
