Biologische Aktivität
OTUB2-IN-1 (0-40 μM) reduces PD-L1 levels in tumor cells (NCI-H358, SK-MES-1, and NCI-H226) in a dose-dependent manner, but it is unable to affect OTUB2 stability[1].
OTUB2-IN-1 (0-50 μM; 1 h) does not interfere with protein interactions between OTUB2 and PD-L1[1].
OTUB2-IN-1 (10 μM; 0-4 d) can’t inhibit the viability of B16-F10 tumor cells[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:B16-F10 tumor cells
-
Concentration:10 μM
-
Incubation Time:0-4 d
-
Result:OTUB2-IN-1 did not show significant inhibitory effects on the viability of B16-F10 tumor cells over a period of up to four days.

Result:Reduced PD-L1 levels in a dose-dependent manner across these cell lines, indicating effective inhibition of OTUB2's functional activity regarding PD-L1 stabilization.
However, it did not affect the stability of OTUB2 itself, suggesting that the inhibitor specifically disrupts the PD-L1 regulatory function of OTUB2 without altering OTUB2 protein stability.
OTUB2-IN-1 （20 mg/kg; i.p.; daily for five days）reduces the expression of YAP and phosphorylated p65 in mice implanted with LL/2 cells; reduces phosphorylated Akt expression in mice implanted with B16-F10 cells and it reduces phosphorylated p65 expression in mice implanted with KLN205 cells[1].

Animal Model:C57BL/6 mice implanted with B16-F10 cells or LL/2 cells [1]
-
Dosage:20 mg/kg; daily for five days
-
Administration:i.p
-
Result:Reduced the expression of PD-L1 on tumor cells, suggesting its potential in enhancing immune recognition and response against tumor cells.
Did not significantly impact tumor cell viability directly, indicating its action might be more about modulating immune evasion mechanisms rather than cytotoxic effects.
Increased the infiltration of cytotoxic T cells within the tumors, suggesting that reducing PD-L1 levels can indeed make the tumor more susceptible to immune attack.within the tumors, suggesting that reducing PD-L1 levels can indeed make the tumor more susceptible to immune attack.

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.
For the following dissolution methods, please prepare the working solution directly:
It is recommended to prepare fresh solutions and use them promptly within a short period of time.
