Adaphostin (NSC-680410) is the adamantyl ester of AG957, acting as a novel and potent activator of Fas-mediated death pathway in Bcr/Abl-positive leukaemia. It also causes apoptosis in T-lymphoblastic human leukemia cell lines (IC50 ranging from 17 to 216 nM) as a p210bcr/abl inhibitor (IC50=14 μM).

Biological Activity
| ln Vitro |
Adaphostin inhibits granulocyte colony formation in specimens of chronic myelogenous leukemia (CML) at lower concentrations without increasing toxicity in normal progenitors and down-regulates p210bcr/abl in K562 cells[1]. N-acetylcysteine (NAC) inhibits adipostin-induced p53 up-regulation, DNA strand breaks, and ROS production in ML-1 cells[4]. |

Solubility Data
| Solubility (In Vitro) | DMSO: ~50 mg/mL (~127.1 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (6.35 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), 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 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: ≥ 2.5 mg/mL (6.35 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 25.0 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.  (Please use freshly prepared in vivo formulations for optimal results.) |
