WebFeb 23, 2024 · Bitopic ligands, that is, ligands that bind to the orthosteric and allosteric-binding site simultaneously, have first been described for muscarinic receptors and have been shown to have an extended binding mode [[107-112]]. This is similar to the binding mode of biased ligands at dopamine, serotonin, and β-adrenergic receptors (Fig. 4). WebLigands are ions or neutral molecules that bond to a central metal atom or ion. Ligands act as Lewis bases (electron pair donors), and the central atom acts as a Lewis acid (electron pair acceptor). Ligands have at least one donor atom with an electron pair used to form covalent bonds with the central atom. The term ligand come from the latin ...
