[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.
The present invention is directed to radiolabeled CGRP receptor antagonists which are useful for the quantitative imaging of CGRP receptors in mammals.
