LY1
Based on 1 Customer Validation
LY1 is a potent, selective and covalent inhibitor against both SARS-CoV-2 PLpro and Mpro with Kd values of 1.5 μM and 2.3 μM for Mpro C145A protein and PLpro C111A protein, respectively. LY1 potent against the viral proteases, with IC50s of 0.12 μM and 0.99 μM against Mpro and PLpro. LY1 shows high selectivity over other kinases, human proteases and metalloenzyme.

제품 설명
IC50 & Target
Kd: 1.5 μM (Mpro C145A protein) and 2.3 μM (PLpro C111A protein)[1].
IC50: 0.12 μM (Mpro protease) and 0.99 μM (PLpro protease)[1].
In Vitro
In SARS-CoV-2-infected Vero E6 cells, LY1 causes a dramatic reduction in the viral nucleoprotein (NP) levels with 5 μM. A 99.99% reduction in the viral RdRP RNA levels is observed with 15 μM LY1[1].
LY1 against cathepsin B and cathepsin L with the IC50 values of 8.8 μM and 2.2 μM, respectively[1].

In Vitro:
DMSO : 50 mg/mL (116.03 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (protect from light, stored under nitrogen). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

In Vivo:
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (5.80 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (5.80 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
