¹²³I-Iododexetimide Preferentially Binds to the Muscarinic Receptor Subtype M₁In Vivo

Abstract

The current results suggest that (123)I-iododexetimide preferentially binds to M1R in vivo and can be displaced by M1R ligands. (123)I-iododexetimide may therefore be a useful imaging tool as a way to further evaluate M1R changes in neuropsychiatric disorders, as a potential stratifying biomarker, or as a clinical target engagement biomarker to assess M1R.
