SP-141 is a novel, cell-permeable, selective and high affinity MDM2 inhibitor (Ki = 28 nM) with excellent in-vitro and in-vivo anticancer activity. Directly binding to MDM2, SP 141 causes MDM2 autoubiquitination and proteasomal degradation in addition to inhibiting MDM2 expression. SP 141 has been shown to slow the growth of tumors created from breast cancer xenografts.
| Targets |
MDM2 (IC50 < 0.50 μM)

|---|---|
| ln Vitro |
SP141 can bound directly to MDM2, promoting its auto-ubiquitination and degradation by the proteasome. With 50% inhibitory concentrations <0.5 μM (0.38–0.50 μM), SP141 decreases MDM2 levels in pancreatic cancer cell lines as well as their proliferation. Regardless of whether pancreatic cancer cell lines expressed functional P53, increasing SP141 concentrations cause an increase in apoptosis and G2-M phase arrest. [1]
|
| ln Vivo |
SP-141 (40 mg/kg; administered by i.p. injection; 5 d/wk for about three weeks) inhibits the development of pancreatic tumors In orthotopic and xenograft mouse models.
|
| Cell Assay |
The human pancreatic cancer cell lines HPAC, Panc-1, AsPC-1, and Mia-Paca-2 are subjected to various SP141 concentrations or vehicle controls. The effects of SP141 on cell viability, colony formation, proliferation (BrdUrd incorporation assay), apoptosis, and cell cycle distribution are then assessed using cells (MTT assay, colony formation, proliferation, 39, and cell proliferation).

| Solubility (In Vitro) |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (6.41 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 20.8 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: ≥ 2.08 mg/mL (6.41 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 20.8 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.) |

*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.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
