SIRT2 15.5 μM (IC50) |
AK-7 (10 μM) reduces cholesterol levels in naive N2a neuroblastoma cells and hippocampal slice cultures from wild-type mice. AK-7 (1 μM) shows neuroprotective effect of AK-7 in striatal Huntington’s disease (HD) neurons[1]. AK-7 (12.5 μM) decreases ratio of DA neurons in primary midbrain cultures[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 (5.72 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.

Protokoll
Neuronal nuclear antigen (NeuN)-positive neurons and some astroglia are derived from mechanically dissociated ganglionic eminences of E16 rat embryos. The HD model is based on the expression of mutant huntingtin. Treatments of cultures with AK-7 are at 10 μM for 24 h unless stated otherwise. DMSO is included at the same concentrations as a control. Lower dose, chronic treatments with AK-7 are introduced to neurons at DIV4 and continued weekly coinciding with normal medium change[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
AK-7, solubilized at 1.5 mg/mL in 25% Cremophor EL (BASF)/ 10% DMSO in water, is administered by intraperitoneal injection to 11 week old mice at 15 mg/kg/dose, and compound levels in serum and brain are measured following sacrifice. Blood is collected and centrifuged at 7,000 rpm for 7 min, and then serum is aspirated and immediately frozen in liquid nitrogen. Brains are immediately frozen in liquid nitrogen and stored at −80°C. Brains are weighed and then homogenized in four volumes of 10% Cremophor RH40 in water using a Polytron homogenizer, and 2% v/v phosphoric acid is added to the homogenate, vortexed, and centrifuged at 10,000 g at 25°C for 1 h. The supernatant is aspirated, and solid phase extraction is performed immediately. Serum samples are vortexed into 2% v/v phosphoric acid and centrifuged at 2500 rpm for 10 min[1].
