(–)-IHCH7041

(–)-IHCH7041 is a potent, selective partial agonist at DRD2/3 and 5-HT1AR, EC50 of 1.38 nM in Gαi1–γ9 dissociation and 2.75 nM in β-arrestin2 recruitment assays, with negligible 5-HT2AR binding (>100-fold selectivity).(–)-IHCH7041 exhibits negligible affinities for a large number of tested GPCRs, ion channels and transporters (Ki>500 nM), good affinities for DRD2 and DRD3 (Ki=14.42 nM), and moderate binding to 5-HT1A (Ki=60.62 nM).(–)-IHCH7041 behaves as a partial agonist in both G-protein signaling and β-arrestin recruitment activities at DRD2, DRD3 and 5-HT1AR.(–)-IHCH7041 displayed potent antipsychotic activity and has antidepressant properties and reverses cognitive impairmentin mice.
