ACTIVE MOIETY
However, it is not clear what role the inhibition of central CGRP-R plays in migraine pain relief. To this end, the CGRP-R positron emission tomography (PET) tracer ((11)C)MK-4232 (2-((8R)-8-(3,5-difluorophenyl)-6,8-(6-(11)C)dimethyl-10-oxo-6,9-diazaspiro(4.5)decan-9-yl)-N-((2R)-2'-oxospiro(1,3-dihydroindene-2,3'-1H-pyrrolo(2,3-b)pyridine)-5-yl)acetamide) was discovered and developed for use in clinical PET studies. In rhesus monkeys and humans, ((11)C)MK-4232 displayed rapid brain uptake and a regional brain distribution consistent with the known distribution of CGRP-R. Monkey PET studies with ((11)C)MK-4232 after intravenous dosing with CGRP-R antagonists validated the ability of ((11)C)MK-4232 to detect changes in CGRP-R occupancy in proportion to drug plasma concentration. Application of ((11)C)MK-4232 in human PET studies revealed that telcagepant achieved only low receptor occupancy at an efficacious dose (140 mg PO).
