The interaction of ibogaine and phencyclidine (PCP) with human (h) α3β4 nicotinic acetylcholine receptors (AChRs) in different conformational states was determined using radioligand binding assays, Ca 2+ influx detections, thermodynamic and kinetic measurements. The results show that ibogaine inhibits (±)‐epibatidine‐induced Ca 2+ influx in hα3β4 AChRs with ~9‐fold higher potency than PCP, [ 3...

The interaction of ibogaine analogs with nicotinic acetylcholine receptors (AChRs) in different conformational states was studied by functional and structural approaches. The results established that ibogaine analogs: (a) inhibit (±)-epibatidine-induced Ca²⁺ influx in human embryonic muscle AChRs with the following potency sequence (IC(50) in μM): (±)-18-methylaminocoronaridine...

We compared the interaction of several catharanthine alkaloids including, ibogaine, vincristine, and vinblastine, with that for the noncompetitive antagonist phencyclidine (PCP) at muscle nicotinic acetylcholine receptors (AChRs) in different conformational states. The results established that catharanthine alkaloids: (a) inhibit, in a noncompetitive manner, (+/-)-epibatidine-induced Ca(2+)...
