Molecular docking models of a) ivacaftor bound to the 5-hydroxytryptamine (5-HT; serotonin) 5-HT2C receptor and b) ivacaftorcarboxylate (iva-M6) bound to the 5-HT2A receptor. Ivacaftor, iva-M6 and residues within the receptor cavity are shown in ball-and-stick representation. The 5-HT2C and 5-HT2A receptors are shown in cartoon ribbon representation. The labelled side chains within the binding cavity represent contacts within 4 Å of the docked molecules.
