Biological Activity

SIRT2 12.5 μM (IC50) |
AK-1 achieves significant neuroprotection in Huntington’s disease flies at 10 μM, improving the number of rhabdomeres from 5.2 to 5.6[1]. AK-1 is a potent, specific and cell-permeable SIRT2 inhibitor, with an IC50 of 12.5 μM[2]. AK-1 treatment induces proteasomal degradation of the Snail transcription factor through inactivation of the NF-κB/CSN2 pathway. Reduction in the level of Snail results in upregulation of p21, leading to G1 arrest, slow proliferation, and slow wound-healing activity. The regulation of Snail-p21 axis by AK-1 also occurs in HT-29 colon cancer cells[3]. Under hypoxic conditions, AK-1 increases the ubiquitination of HIF-1α in a VHL-dependent manner, leading to the degradation of HIF-1α via a proteasomal pathway. Downregulation of HIF-1α expression reduces its transcriptional activity and, eventually, reduces the expression of BNIP3, one of HIF-1 target genes, in AK-1-treated cells[4].

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.

Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocol
HEK293 cells are co-transfected with 3 μg of pGL2-PGK1-HRE-Luc and 1 μg of pCMV-β-galactosidase plasmids. Twenty-four hours later, the cells are incubated under hypoxic conditions for 24 hr in the presence of 10 μM AK-1 and then lysed with luciferase cell lysis buffer. Luciferase and β-galactosidase activities are measured using luciferin and ο-nitrophenyl-β-d-galactopyranoside, respectively, as substrates. Transfection efficiency is normalized according to β-galactosidase activity[3].
