Biological Activity
Usp22i-S02(USP22-IN-1, compound S02) is a potent inhibitor of ubiquitin specific peptidase 22 (USP22). It showed anticancer activity by suppressing Foxp3 expression in T-regulatory cells.
In Vitro
USP22-IN-1 (compound S02) reduces the expression of Foxp3 MFI and cell viability in a dose-dependent manner at concentrations of 0, 5, 10, 15, 20, and 25 µg/mL [1]. At a concentration of 10 µg/mL and during an incubation time of 0-12 hours, USP22-IN-1 decreases the expression levels of FOXP3, USP22 protein, and Foxp3 mRNA in iTreg cells [1]. The Cell Viability Assay showed that cell survival was inhibited in a dose-dependent manner [1]. Western Blot Analysis revealed that the expression of FOXP3 and USP22 decreased in a time-dependent manner when cells were treated with 10 µg/mL of USP22-IN-1 [1].
In Vivo
USP22-IN-1 (20 mg/kg; i.p.; twice a day for 5 days) enhances the anti-tumor immunity in mice [1]. The study used male C57BL/6 mice (6-8 weeks old) with LLC1 cells [1]. The dosage administered was 20 mg/kg via intraperitoneal injection, given twice a day for 5 days [1]. The results showed an improvement in anti-tumor immunity, leading to decreased tumor cell counts, reduced viability, and inhibited tumor growth [1].
