Description

Trimipramine maleate is a 5-HT receptor antagonist, with pK_i binding values of 6.39, 8.10, 4.66 for 5-HT_1C, 5-HT₂ and 5-HT_1A, respectively^[1]. Trimipramine maleate is also a potent and selective inhibitor targeting human noradrenaline (hNAT), serotonin (hSERT) and organic cation transporters (hOCT1, hOCT2) with IC₅₀ values of 4.99 μM, 2.11 μM, 3.72 μM, 8.00 μM, respectively^[2]. Trimipramine maleate has vascular activity and anxiolytic efficacy^[3].

In Vitro

Trimipramine maleate displays much higher affinity for 5-HT₂ than for 5-HT_1C receptors^[1].
Trimipramine maleate is a moderate inhibitor of the human NAT and SERT, with the IC₅₀ values of 4.99 μM and 2.11 μM, respectively^[2].
SERT and NAT could represent a target for the antidepressant effects of trimipramine maleate (1 mM, 0.1 mM, 0.01 mM, 1 μM, 0.1 μM; 10 min; HEK293 cells)^[2].

In Vivo

Trimipramine maleate (5 mg/kg/d; 14 d; chronic administration) acts as functions in rats:1. Increasing concentration of regional 5-HT. 5-HT is highest in the frontal cortex and the hippocampus, followed by the olfactory tubercles and the hypothalamus. 2. Decreasing the number of frontal cortex 5-HT₂ and striatal DA D₂ receptors. 3. Increasing in the brain regional level of monoamines and metabolites. thus indicates a greater synthesis rate for dopamine (DA) and 5-HT coinciding with an adaptive down regulation of 5-HT₂ and DA D₂ receptors^[3].

Animal Model:	Male Wistar rats (220-250 g); implanted osmotic minipump subcutaneously in the dorsal thoracic interscapular region^[3]
Dosage:	5 mg/kg/day
Administration:	Delivered by smotic minipump; 14 days
Result:	Decreased the number of frontal cortex 5-HT₂ and striatal DA D₂ receptors, thus blocked the uptake of 5-HT and dopamine (DA).

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 (6.09 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% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (6.09 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 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.5 mg/mL (6.09 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.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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.
