Biological Activity


ln Vitro While PBOX 6 is a strong apoptotic PBOX, in the rat R2C Leydig cell line it has no general harmful effects. PBOX 6 (0-25 μM, 16 h) induces apoptosis in HL-60 cells in a dose- and time-dependent manner. At 10 μM, it also fragments DNA. PBOX 6 (10 μM) activates caspase 3-like protease in HL-60 cells, causing them to undergo apoptosis. PBOX 6 (10 μM) causes apoptosis and cytochrome accumulation in the cytoplasm; however, oxidative stress is not responsible for this impact, nor is it dependent on NF-κB or peripheral benzodiazepine receptors (PBR)[1]. By activating caspase-7, PBOX 6 (25 μM) causes MCF-7 cells to undergo apoptosis[2]. In K562 cells, PBOX 6 (10 μM) causes cypA to be redistributed from the nucleus to the cytoplasm. Trypsin-like serine proteases must be activated upstream in order for PBOX 6 (10 μM) to cause the nucleocytoplasmic translocation of cypA and pin1 in a JNK-dependent manner. This result is linked to G2/M phase arrest in K562 cells [3].

Solubility Data


Solubility (In Vitro) DMSO : ~33.33 mg/mL (~84.07 mM)
Solubility (In Vivo) Solubility in Formulation 1: ≥ 2.5 mg/mL (6.31 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.

 (Please use freshly prepared in vivo formulations for optimal results.)
Preparing Stock Solutions 1 mg 5 mg 10 mg

10 mM 0.2522 mL 1.2612 mL 2.5224 mL
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
