Biological Data

Biological description

Perlapine dihdrochloride is the water soluble of perlapine which is a potent agonist at muscarinic based DREADDs such as the excitatory hM3Dq, hM1Dq and inhibitory hM4Di DREADDs (pEC50 values are 8.08, 8.38 and 7.27 at hM3Dq, hM1Dq and hM4Di respectively).

Perlapine exhibits >10,000-fold selectivity for hM3Dq over wildtype hM3 and interacts with wildtype hM1 and hM4 receptors with relatively low affinity. Perlapine lacks agonist activity at wild type receptors.

It has been reported that perlapine does not undergo back metabolism to clozapine.

Perlapine also acts as a sleep inducing, hypnotic agent.

CNO dihydrochloride (water soluble), Clozapine N-oxide (CNO) freebase, Compound 21, Salvinorin B (SalB) and perlapine freebase also available.
