ln Vitro |
RU-SKI 43 hydrochloride (10 μM; for 6 days) greatly inhibits cell proliferation (83% in AsPC-1 cells) in AsPC-1 and Panc-1 cells[2]. RU-SKI 43 hydrochloride (10 or 20 μM; 5 hours) produces dose-dependent suppression of Shh palmitoylation following only 5 hours[1]. RU-SKI 43 hydrochloride (10 μM; for 72 hours) causes a 40% drop in Gli-1 levels in AsPC-1 cells[2] . RU-SKI 43 hydrochloride (10 μM; 48 hours) leads in reduced phosphorylation (47-67%) of four proteins in the Akt pathway, including Akt (phosphorylation at both Thr307 and Ser473), PRAS40, Bad and GSK-3β. RU-SKI 43 therapy also reduces phosphorylation of mTOR and S6, components of the mTOR signaling pathway[2]. RU-SKI 43 hydrochloride functions as an uncompetitive inhibitor (Ki=7.4 μM) with regard to Shh, and as a noncompetitive inhibitor ( Ki=6.9 μM) with respect to 125I-iodo-palmitoylCoA[1].

ln Vivo |
After being administered intravenously, RU-SKI 43 hydrochloride has a t1/2 of 17 min in mouse plasma[1].

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (5.91 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 (5.91 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.) |

*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.
