  [¹¹C]MK-4232: The First Positron Emission Tomography Tracer for the Calcitonin Gene-Related Peptide Receptor

  摘要：

  Rational modification of the potent calcitonin gene-related peptide (CGRP) receptor antagonist MK-3207 led to a series of analogues with enhanced CNS penetrance and a convenient chemical handle for introduction of a radiolabel. A number of C-11-tracers were synthesized and evaluated in vivo, leading to the identification of [C-11](8) ([C-11]MK-4232), the first positron emission tomography tracer for the CGRP receptor.
