CMPI hydrochloride, a potent and selective nAChR agonist, functions as a positive allosteric modulator (PAM) specifically targeting the α4:α4 subunit interface of the nAChR. It enhances the response of the (α4)3(β2)2 nAChR to acetylcholine (ACh) (10 μM) with an EC 50 of 0.26 μM. With its potential for researching nicotine dependence and various neuropsychiatric conditions linked to reduced brain cholinergic activity, CMPI hydrochloride stands as a significant compound in neurological research.

| In vitro | CMPI (0.01-10 μM) enhances the activity of (α4)3(β2)2 nAChRs, characterized by low acetylcholine sensitivity, without affecting (α4)2(β2)3 nAChRs, which exhibit high acetylcholine sensitivity, in Xenopus laevis oocytes[1]. Furthermore, CMPI (0.01-10 μM) demonstrates inhibition of (α4)2(β2)3, human muscle, and Torpedo nAChRs in Xenopus oocytes, with respective IC50 values of 0.6, 0.7, and 0.2 μM[1]. |
