7ACC2 (compound 19; 72 hours) inhibits SiHa cells proliferation in lactate-containing medium with an EC50 of 0.22 μM. In SiHa cells, lactate uptake primarily depends on the high affinity MCT1 transporter[1].
7ACC2 (compound 19) shows an excellent chemical stability in simulated gastric (SGF) and intestinal (SIF) fluids, a good apparent permeability coefficient (Papp) through Caco-2 monolayer and a high metabolic stability on mouse (MLM) and human liver microsomes (HLM) as well as on human hepatocytes[1].
7ACC2 is a potent inhibitor of mitochondrial pyruvate transport which consecutively blocks extracellular lactate uptake by promoting intracellular pyruvate accumulation[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
The intraperitoneal administration of 7ACC2 (compound 19; 3 mg/kg) to mice leads to a Cmax of 1246 ng/ml (4 μM) in a very short time (Tmax=10 min) associated with a plasma half-life of 4.5 h[1].

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 (8.08 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
