Bioactivity Comments
Data supports pirenzepine-induced dimerization of the receptors (through FCS) and a three-step binding model fully describes describing the formation of a first ligand-receptor complex (RL*) that slowly interconverts into a more stable one (RL), prone to subsequent dimerization (R2L2).
