Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O	0.75mg/ml	Taking the 1 mL working solution as an example, add 50 μL of 15 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.
Clear solution	5% DMSO 1 95% Corn oil	0.18mg/ml	Taking the 1 mL working solution as an example, add 50 μL of 3.6 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description

PCNA-I1 is a selective inhibitor of proliferating cell nuclear antigen (PCNA, a potential anticancer target). PCNA-I1 selectively binds to PCNA trimers with Kd of ~0.2 to 0.4 μM. PCNA-I1 inhibits the growth of tumor cells of various tissue types with IC50 of ~0.2 μM. PCNA-I1 induces DNA damage and apoptosis in both LNCaP and PC-3 cells. PCNA-I1 also induces autophagy in PC-3 cells.

Targets

PCNA trimers ^[1]
(Cell-free assay)

0.2 to 0.4 μM(Kd)

In vitro

PCNA-I1 prevents the transportation of the Proliferating Cell Nuclear Antigen (PCNA) to the cytoplasm by stabilizing its trimer form in the nucleus, thus inhibits SARS-CoV-2 replication.^[3]

Protocol (from reference)

Cell Assay:^{^[3]}	Cell lines Vero E6 cells Concentrations 0.1, 1, 10 and 100 µM Incubation Time 96 h Method Lung tissue sections A plaque assay was performed. Briefly, after seeding, Vero E6 (8 × 10⁵ cells per well, 6-well plates) were incubated overnight and infected with 200 PFU per well. PCNA-I1 or Verdinexor were added at final concentrations of 0.5 µM or 0.1 µM and 0.1 µM or 1 µM, in overlays composed of DMEM supplemented with 10% FBS plus carboxymethylcellulose sodium salt 2%, immediately post-viral adsorption. A MTT cell proliferation assay was done to verify the toxicity of the drugs. After four days, cells were fixed with formaldehyde and stained with crystal violet to count plaques.
