AK59 is a STING degrader leveraging HERC4, a HECT-domain E3 ligase [1]. AK59 inhibits the cGAS/STING signaling pathway by promoting STING degradation through the ubiquitin-proteasome system (UPS) [2]. AK59 is frequently used in biochemical experiments to screen STING inhibitors and STING mutant-specific degraders [3].

| Cell experiment [1]: | |
Cell lines | THP1 cells |
Preparation Method | THP1 cells were cultured in RPMI 1640 medium containing 10% fetal bovine serum (FBS), 2mM l-glutamine, 25mM Hepes, 1mM sodium pyruvate, and 50U/ml penicillin and 100mg/ml streptomycin at 37℃ in the presence of 5% CO2. 2×106 per well in a six-well plate were seeded and treated with different concentrations of AK59 (1, 2, 5, 7.5, 10µM) for 16h. Subsequently, Western blot analysis was conducted. |
Reaction Conditions | 1, 2, 5, 7.5, 10µM; 16h |
Applications | AK59 treatment significantly reduced STING protein expression in THP1 cells in a dose-dependent manner. |

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL saline, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
