PCNA-I1
Based on 1 Customer Validation
PCNA-I1 is a selective small molecule inhibitor targeting proliferating cell nuclear antigen (PCNA) with anticancer activity. PCNA-I1 can stabilize the PCNA trimer structure (Kd=0.14-0.41μM), reduce its binding to chromatin, induce tumor cell cycle arrest, inhibit DNA replication and repair, and enhance the anti-tumor effect of DNA damaging agents. PCNA-I1 can be used in the study of targeted therapy for prostate cancer, lung cancer and other tumors.

Activité biologique
PCNA-I1 (0.05-10 μM; 72 h) inhibits the cell viability of human prostate cancer (PC-3, LNCaP), breast cancer (MCF-7), melanoma (A375) cell lines in a concentration-dependent manner, with an average IC50 of 0.17 μM, which is significantly lower than that of normal cells[1].
PCNA-I1 (1 μM; 24-48 h) induces cell cycle arrest in S and G2/M phases and increases cell apoptosis[1].
PCNA-I1 (1 μM; 48 h) reduces PCNA binding to chromatin in PC-3 cells (NP-R fragment decreased by 50%), accompanied by nuclear p21 aggregation[1].
PCNA-I1 (1 μM; 24 h) increases the expression of γH2AX (a DNA damage marker) in PC-3 cells[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:PC-3, LNCaP (prostate cancer); MCF-7 (breast cancer); A375 (melanoma)
-
Concentration:0.05, 0.1, 0.5, 1, 5, 10 μM
-
Incubation Time:72 h
-
Result:Dose-dependent inhibited cell growth with IC50 values: PC-3 (0.24 μM), LNCaP (0.14 μM), MCF-7 (0.15 μM), A375 (0.16 μM), while exhibited IC50 >1 μM against normal cells (e.g., HUVEC, mesenchymal stem cells).

-
Animal Model:Male BALB/c nude mice (8-10 weeks old) bearing LNCaP prostate cancer xenografts[3]
-
Dosage:10 mg/kg
-
Administration:Intravenous injection, 5 days/week for 2 consecutive weeks
-
Result:Significantly retarded tumor growth, with tumor weight in treated mice being 28% of that in vehicle controls. No significant changes in body weight or hematology profiles (leukocytes, erythrocytes, thrombocytes) were observed, indicating minimal systemic toxicity.
