Based on 1 publication(s) in Google Scholar
Jun12682 is an orally active SARS-CoV-2 papain-like protease (PLpro) inhibitor, with a Ki value of 37.7 nM and an EC50 value of 1.1 μM in the FlipGFP PLpro assay. Jun12682 has efficacy in hindering PLpro both deubiquitination and deISGylation, with Ki values of 63.5 and 38.5 nM, respectively. Jun12682 exhibits resistance in multiple PLpro mutant strains, and its enzymatic activity is comparable to that of the wild-type. Jun12682 can be used for the study of the SARS-CoV-2.

Actividad biológica
Jun12682 inhibits the replication of the SARS-CoV-2 virus, with EC50 values of 0.42 and 0.51 μM in the icSARS-CoV-2-nLuc reporter virus and plaque assays, respectively[1].
Jun12682 is highly stable in the human microsomes (T1/2 = 131.9 min, CLint (mic) = 10.5 μL/min/mg)[1].
Jun12682 shows consistent antiviral activity against SARS-CoV-2 delta and omicron variants and Nirmatrelvir (HY-138687)-resistant strains (rNsp5-S144M, rNsp5-L50F/E166V and rNsp5-L50F/E166A/L167F) in Caco-2 cells (EC50: 0.44-2.02 μM)[1][2].
Jun12682 has no inhibitory activity on the related human proteases USP7 and USP14 and cytochrome P450 (CYP450) enzymes, including CYP1A2, 2C9, 2C19, 2D6 and 3A-M (IC50 > 50.0 mM)[1][2].

Animal Model:lethal SARS-CoV-2 model established in young BALB/c mice (9 to 12 weeks old)[1]
-
Dosage:125 and 250 mg/kg for 3 days and 500 mg/kg for 5 days
-
Administration:Oral administration (p.o.), twice daily for 3 or 5 days
-
Result:Exhibited reduced weight loss, resulting in a significantly improved survival rate and the three-day treatment of 250 mg/kg dose conferred even better protection.
Had statistically lower lung viral titers and considerably decreased viral antigen staining levels with a few sporadic positive cells.
Significantly reduced the viral N gene level and the expression of multiple inflammatory cytokines, including IFN-β, IL-1β, IL-6, and CXCL10 (36).

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 (4.99 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 (4.99 mM); Clear solution
