ln Vitro |
ZL0420 forms crucial interactions with Asn140 directly and Tyr97 indirectly through an H2O molecule when it is properly docked into the acetyl-lysine (KAc) binding pocket of BRD4. In cultured human small airway epithelial cells (hSAECs), ZL0420 demonstrates submicromolar potency of suppressing the TLR3-dependent innate immune gene program, including ISG54, ISG56, IL-8, and Groβ genes, with IC50s of 0.49-0.86 µM[1].
|
ln Vivo |
ZL0420 has a strong, low-toxicity effect on airway inflammation in a mouse model. ZL0420 exhibits remarkable efficacy and almost eliminates the deep-seated neutrophil build-up surrounding small and medium-sized airways that is brought on by the administration of poly(I:C)[1].

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (7.02 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 (7.02 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 20.8 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.) |

5 mM | 0.6749 mL | 3.3747 mL | 6.7495 mL | |
10 mM | 0.3375 mL | 1.6874 mL | 3.3747 mL |
*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.
