8-OH-DPAT purchased from MedChemExpress. Usage Cited in: Acta Pharmacol Sin. 2025 Oct 9. [Abstract]

Microinjecting 8-OH-DPAT (4 mM) into the dorsal raphe nucleus (DRN), followed by esflurbiprofen treatment (20 mg/kg, intraperitoneally) at 5 min. TST (F (3, 28) = 6.237, P = 0.0022), FST (F (3, 28) = 4.385, P = 0.0119) were performed 2 h post treatment (n = 8). The results showed that 8-OH-DPAT, a selective 5-HT₁A receptor agonist, abolished the rapid antidepressant activity of esflurbiprofen, confirming that esflurbiprofen exerted antidepressant effects by inhibiting the negative feedback mediated by 5-HT₁A autoreceptors.

8-OH-DPAT purchased from MedChemExpress. Usage Cited in: J Ethnopharmacol. 2026 Feb 28:357:120876. [Abstract]

Microinjecting 8-OH-DPAT (4 mM) into the dorsal raphe nucleus (DRN) followed by AITC ME treatment. TST (F (3,28) = 3.435, P = 0.0303, n = 8) and FST (F (3,28) = 14.79, P < 0.0001, n = 8) were performed 2 h later. The results showed that 8-OH-DPAT, a 5-HT₁AR agonist, abolished the antidepressant activity of AITC ME, indicating that the antidepressant effect of AITC ME was associated with the autoreceptor-mediated negative feedback mechanism of 5-HT₁AR in the DRN.

Co-administration of the sigma-1 receptor (S1R) agonist SA-4503 (1 mg/kg, i.p.) and the 5-HT₁A receptor agonist 8-OH-DPAT (0.3 mg/kg, i.p.) produced synergistic anxiolytic- and antidepressant-like effects.

Statistical analysis of the percentage of c-Fos+ TPH2+ cells in the experimental groups of mice (n = 6, with samples from at least three mice per group). The results showed that treatment with SA-4503 (1.0 mg/kg; p.o. ; once daily for 3 days), alone or in combination with 8-OH-DPAT (0.3 mg/kg ; i.g.; once daily for 3 days), activated a greater number of serotonergic neurons in the DRN of mice subjected to CRS. Similarly, the combined treatment significantly enhanced the effect of 8-OH-DPAT alone (P = 0.0022).

Stock Solution Working Solution

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: ≥ 5 mg/mL (20.21 mM); Clear solution

This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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.

Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)

Solubility: ≥ 5 mg/mL (20.21 mM); Clear solution

This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

Protocol 3

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

Solubility: ≥ 5 mg/mL (20.21 mM); Clear solution

This protocol yields a clear solution of ≥ 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 (50.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Animal Administration^[3]

Mice^[3]
The locomotor activity of mice is measured by an infrared sensor placed in individual home cages. To compare the locomotor activity in the light and dark periods, locomotor activity is monitored at 30-min intervals starting at 8:00 a.m. and 8:00 p.m., respectively. To measure the effects of psychostimulants (8-OH-DPAT, 1, 3 mg/kg, s.c; etc.) on locomotor activity in the dark period, all drugs are administered at 8:00 p.m., and locomotor activity is then measured through 3 h^[3].

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
