Deoxytopsentin (compound 5) (10 μM; 240 nM) effectively inhibited recombinant Staphylococcus aureus PK with an IC50 value of 240 nM, and its selectivity for Staphylococcus aureus PK at a concentration of 10 μM was significantly higher than that for human PK isoenzymes [1]. Deoxytopsentin has in vitro antibacterial activity against both methicillin-sensitive and methicillin-resistant Staphylococcus aureus strains, and its activity against three methicillin-resistant Staphylococcus aureus (MRSA) strains is comparable to or stronger than that of oxacillin [1]. Deoxytopsentin binds to the hydrophobic small interface binding pocket of MRSA PK and forms predicted π-π stacking and hydrogen bond interactions with key amino acid residues in the pocket [1].

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (7.66 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween-80 + 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 canAdd 100 μL of DMSO stock solution (25.0 mg/mL) to 400 μL of PEG300 and mix well; then add 50 μL of Tween-80 and mix well; finally add 450 μL of physiological saline and adjust the volume to 1 mL. Preparation of physiological saline: Dissolve 0.9 g of sodium chloride in double-distilled water and dilute to 100 mL to obtain clear physiological saline. 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 (7.66 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 canAdd 100 μL of DMSO stock solution (25.0 mg/mL) to 900 μL of 20% SBE-β-CD saline and mix well. Preparation of 20% SBE-β-CD saline (4°C, store for one week): Dissolve 2 g of SBE-β-CD powder in 10 mL of saline until completely dissolved and clear. 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. View More
Solubility in Formulation 3: ≥ 2.5 mg/mL (7.66 mM)(saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), Clear solution. |

*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.
