1. Deschloroclozapine

Deschloroclozapine, a metabolite of Clozapine, is a highly potent muscarinic DREADDs agonist. Deschloroclozapine binds to DREADD receptor subtypes hM3Dq and hM4Di with Ki of 6.3 and 4.2 nM, respectively. [11C]-Deschloroclozapine is developed as a promising PET tracer for DREADD imaging.

Description

Deschloroclozapine, a metabolite of Clozapine, is a highly potent muscarinic DREADDs agonist. Deschloroclozapine binds to DREADD receptor subtypes hM3Dq and hM4Di with Ki of 6.3 and 4.2 nM, respectively. [11C]-Deschloroclozapine is developed as a promising PET tracer for DREADD imaging[1][2][3].

IC50 & Target

Ki: 6.3 nM (hM3Dq), 4.2 nM (hM4Di)[2]

In Vitro

Designer Receptors Exclusively Activated by Designer Drugs (DREADD) are a chemogenetic approach for remote manipulation of neuronal activity in freely-moving animals. DREADDs comprise mutated G protein-coupled receptors (GPCRs) that do not respond to their endogenous neurotransmitter, but do respond to an otherwise “inert” exogenous substance[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Deschloroclozapine (0.3 mg/kg; intramuscularly) impairs working memory function in male rhesus macaques (aged between 5 and 6 years and weighing 5.5-7.9 kg)[3].
Deschloroclozapine (0.1 mg/kg; i.m) is effective at activating DREADD receptors in vivo and reversibly inducing behavioral effects in monkeys[3].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (8.55 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 2.5 mg/mL (8.55 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
