CSN5-IN-3
CSN5-IN-3 (Compound 30) is a CSN5 inhibitor with an IC50 of 0.58 μM. CSN5-IN-3 inhibits the enzymatic activity of CSN5, leading to increased accumulation of NEDD8-Cul1 and promoting the degradation of PD-L1. CSN5-IN-3 downregulates Bcl-2, and upregulates P53 and Cleaved caspase-3. CSN5-IN-3 exhibits anticancer activity against triple-negative breast cancer.

-
Dosage:8 mg/kg; 16 mg/kg
-
Administration:i.p.; every 3 days; 21 days
-
Result:Achieved 68.3% tumor growth inhibition (TGI) at 8 mg/kg.
Achieved 89.3% tumor growth inhibition (TGI) at 16 mg/kg.
Showed no mortality in either treatment group.
Exhibited no significant body weight changes in the low-dose group; caused a slight temporary body weight decrease but no significant end-of-study weight loss in the high-dose group.
Reduced PD-L1 and Ki67 expression, and increased P21 expression in excised tumors via immunohistochemical analysis.
