Dq with an EC
50
=0.13 nM. Deschloroclozapine is also a potent agonist for hM
4
Di with an EC
50
=0.081 nM.
Deschloroclozapine is a potent and selective agonist for hM
3
Dq and hM
4
Di, it does not display significant agonistic activity for any of the 318 tests wild-type GPCRs at <10 nM.
Deschloroclozapine (100 μg/kg; i.v.) exhibits good brain concentration profiles and biostability. Pharmacokinetic studies confirmed that Deschloroclozapine is rapidly accumulated in mouse brains and monkey CSF, while its metabolites are negligible.
Deschloroclozapine (1 μg/kg; i.p.) selectively and rapidly enhances neuronal activity via hM
3
Dq-DREADD in vivo, Deschloroclozapine can also be utilized for in vivo neuronal silencing by activating hM
4
Di, an inhibitory DREADD.
Deschloroclozapine (1-100 μg/kg; i.v.) selectively induces hM
3
Dq-mediated metabolic activity.
Deschloroclozapine (100 μg/kg; i.m.) selectively induces behavioral deficits in hM

Di-expressing monkeys.
| Animal Model: | Macaque monkey; 2.8-8.0 kg; age 3-10 years |
| Dosage: | 10, 100, 1000, 10000 μg/kg |
| Administration: | I.v. bolus injection |
| Result: | Required the dose for 50% occupancy (ED 50 ) for Deschloroclozapine was 25 μg/kg. |
| Animal Model: | Macaque monkey; 2.8-8.0 kg; age 3-10 years |
| Dosage: | 100 μg/kg (Pharmacokinetic Analysis) |
| Administration: | I.v. injection |
| Result: | Provided a sufficient concentration of Deschloroclozapine by a low systemic dose of Deschloroclozapine to be available for hM 4 Di-DREADD binding in vivo for at least for 2 h without the production of metabolites in monkeys. |
| Animal Model: | Wild-type C57BL/6j mice; male; age >12 weeks |
| Dosage: | 100 μg/kg (Pharmacokinetic Analysis) |
| Administration: | I.p. administration |
| Result: |
Diminished rapidly of Deschloroclozapine concentration and were undetectable at 2 h in either brain tissue or CSF.
The amount of the desmethyl metabolite C21 in CSF was negligible. |
| Animal Model: | HM 3 Dq monkeys and non-DREADD monkeys |
| Dosage: | 1, 3, 100 μg/kg (Pharmacokinetic Analysis) |
| Administration: | I.v. injection |
| Result: | Increased of FDG uptaking after Deschloroclozapine administration occurred exclusively at the hM 3 Dq-positive area. |
| Animal Model: | Monkeys received multiple injections of an AAV-vector carrying hM 4 Di genes |
| Dosage: | 100 μg/kg (Pharmacokinetic Analysis) |
| Administration: | I.m. administration |
| Result: | Enabled a rapidly and reversibly-induced behavioral change through activating muscarinic-based DREADDs without significant side effects. |
