PCNA-I1

Name: PCNA-I1
Brand: Selleck Chemicals
SKU: S4476
Rating: 5 (1 reviews)

Catalog No.S4476 Purity:99.97%

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.

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

0.2 to 0.4 μM(Kd)

In vitro
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]
Cell Research	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.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
