N-methyl-D-aspartate receptors(NMDARs)play critical roles in the physiological function of the mammalian central nervous system(CNS), including learning, memory, and synaptic plasticity, through modulating excitatory neurotransmission. Attributed to etiopathology of various CNS disorders and neurodegenerative diseases, GluN2B is one of the most well-studied subtypes in preclinical and clinical studies on NMDARs. Herein, we report the synthesis and preclinical evaluation of two 11C-labeled GluN2B-selective negative allosteric modulators(NAMs)containing N,N-dimethyl-2-(1H-pyrrolo[3,2-b]pyridin-1-yl)acetamides for positron emission tomography(PET)imaging. Two PET ligands, namely [~(11)C]31 and [~(11)C]37(also called N2B-1810 and N2B-1903, respectively)were labeled with [~(11)C]CH_3I in good radiochemical yields(decay-corrected 28% and 32% relative to starting [~(11)C]CO_2, respectively), high radiochemical purity(>99%)and high molar activity(>74GBq/µmol). In particular, PET ligand [~(11)C]31 demonstrated moderate specific binding to GluN2B subtype by in vitro autoradiography studies. However, because in vivo PET imaging studies showed limited brain uptake of [~(11)C]31(up to 0.5 SUV), further medicinal chemistry and ADME optimization are necessary for this chemotype attributed to low binding specificity and rapid metabolism in vivo.
