Biological Activity
| ln Vitro | When IPAG inhibits Sigma1, PD-L1 in PC3 (hormone-insensitive prostate cancer) and MDA-MB-231 (triple-negative breast cancer) cell lines is autolysosomally degraded, and the amount of functional PD-L1 on the cell surface cells is decreased [2]. 100±8 μg per 106 cells were generated on average after IPAG treatment. IPAG has the ability to stop cell division. Cell mass is decreased by IPAG therapy [3]. The phosphorylation of the translation regulatory proteins p70S6K, S6, and 4E-BP1 is inhibited by IPAG administration [3]. |
| Cell Assay |
Cell Viability Assay[3] Cell Types: T47D Cell Tested Concentrations: 10 μM Incubation Duration: 24 hrs (hours) Experimental Results: The average forward scatter height (FSC-H) of DMSO (control) measured 412±5, while the average FSC-H of IPAG The treated cells were 412±5 and 390±4. Western Blot Analysis [3] Cell Types: T47D Cell Tested Concentrations: 10 μM Incubation Duration: Experimental Results: diminished levels of phosphothreonine 389-p70S6 kinase (P-S6K), phosphoserine 235/236-ribosomal S6 (P-S6) , and phosphoserine 65-4E-BP1 (P-4E-BP1). |

Solubility Data
| Solubility (In Vitro) | DMSO : ~8.33 mg/mL (~21.07 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 0.83 mg/mL (2.10 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 8.3 mg/mL clear DMSO stock solution to 400 μL of PEG300 and mix evenly; then add 50 μL of Tween-80 to the above solution and mix evenly; then add 450 μL of 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: ≥ 0.83 mg/mL (2.10 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 8.3 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: ≥ 0.83 mg/mL (2.10 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 8.3 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.) |
