Biological Activity
| ln Vitro | TMEM173 activation is inhibited by BPK-25 (10 μM; 5 hours) through the cyclic dinucleotide ligand cGAMP [2]. As indicated by a >50% decrease in IκBα phosphorylation, BPK-25 (10 μM; 24 hours) suppresses nuclear factor of activated T cells (NFAT) activation and NF-κB activation [1]. T cell NFATc2 expression is likewise decreased by BPK-25 (10 μM; 4 hours) [1]. In a concentration- and time-dependent manner, BPK-25 (0.1, 1, 5, 10, 20 μM; 24 hours) promotes the substantial and selective decrease of many proteins in the nucleosome remodeling and deacetylation (NuRD) complex. The mRNA expression of BPK-25 did not alter in a similar way [1]. BPK-25-ctrl, the non-electrophilic propionamide analog of BPK-25, does not change NuRD complex proteins in T cells or limit T cell activation [1]. |

Solubility Data
| Solubility (In Vitro) | DMSO: 150 mg/mL (381.83 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: 3.75 mg/mL (9.55 mM) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with sonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 37.5 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 3.75 mg/mL (9.55 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (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 37.5 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. Solubility in Formulation 3: ≥ 3.75 mg/mL (9.55 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 37.5 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.) |
