SKF89976A has a weak antiallodynic action. SKF89976A weakly inhibits serotonin transporter (SERT), noradrenaline transporter (NET), and dopamine transporter (DAT) in chinese hamster ovary (CHO) cells stably expressing each transporter using a substrate uptake assay, with IC50 values of 3514 , 202.13, and 728.8, respectively[1]. SKF89976A is a GABA-transport blocker. GABA (1 mM) elicited an inward current that is completely suppressed by the GABA transport inhibitors tiagabine (10 μM) and SKF89976A (100 μM), but is unaffected by 100 μM picrotoxin. 100 μM SKF 89976-A is known to block the transport of GABA into cells, completely eliminated the GABA-elicited current in a reversible fashion[2]. SKF89976A is a nontransportable blockers of GAT-1. SKF89976-A also suppresses baseline inward currents that likely result from tonic GAT activation by background GABA. SKF89976A (100 μM) reversibly reduces GAT currents in every studied cell by 67.9±4.4% (n=19). Intracellular perfusion of 20 μM SKF89976-A progressively reduced and blocked GABA-induced GAT currents without blocking GABAAR-mediated currents (n=4)[3].

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (6.72 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (6.72 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.
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.

Protocol
CHO cells stably expressing the mouse GAT subtypes, rat serotonin transporter (SERT), rat noradrenaline transporter (NET), and rat dopamine transporter (DAT) are incubated with 10 nM tritium-labeled GABA or monoamines for 10 min in the absence or presence of various concentrations of the GAT inhibitors (e.g., SKF89976A) tested. Values presented for SERT, NET, and DAT are the mean±S.E.M. for 3 experiments, with each being performed in duplicate[1].

Mice[1]
5-week-old ddY male mice, weighing 25-30 g at the beginning of the study are used. Mice are administered NNC05-2090, SKF89976A (0.3 mg/kg, i.p.), (S)-SNAP5114, or amitriptyline. The composition of ACSF (in mM) is 142 mM NaCl, 5 mM KCl, 2 mM CaCl2, 2 mM MgCl2, 1.25 mM NaH2PO4, 10 mM d-glucose, 10 mM HEPES, and 0.05% fatty acid-free bovine serum albumin (pH 7.4). The intraperitoneal (i.p.) injection of drugs is administered in a volume of 0.1 mL/10 g body weight. When given intravenously (i.v.), solutions are injected into the tail vein in a volume of 0.1 mL/10 g body weight. The head of a mouse is placed into a plastic cap and the body is held with one hand for an intrathecal (i.t.) injection. A 27-gauge needle attached to a Hamilton microsyringe is inserted into the subarachnoid space between the L5 and L6 vertebrae of the conscious mouse and 5 mL of the drug solution is slowly injected[1].
