Notes:
2. For more details, such as half maximal inhibitory concentrations (IC50s) and working concentrations of each inhibitor, please click on the link of the inhibitor of interest.
3. "+" indicates inhibitory effect. Increased inhibition is marked by a higher "+" designation.
4. Orange "√" refers to compounds which do inhibitory effects on the related isoform, but without specific value.

Isoform-specific Inhibitors

Catalog No. Information Product Use Citations Product Validations
S1155

S3I-201

S3I-201 shows potent inhibition of STAT3 DNA-binding activity with IC50 of 86 μM in cell-free assays, and low activity towards STAT1 and STAT5.

S1491

Fludarabine

Fludarabine is a STAT1 activation inhibitor and a DNA synthesis inhibitor in Vascular smooth muscle cells.

S7024

Stattic

Stattic, the first nonpeptidic small molecule, potently inhibits STAT3 activation and nuclear translocation with IC50 of 5.1 μM in cell-free assays, highly selectivity over STAT1.

S3030

Niclosamide

Niclosamide can inhibit DNA replication and inhibit STAT with IC50 of 0.7 μM in a cell-free assay.

S4182

Nifuroxazide

Nifuroxazide is a cell-permeable and orally available nitrofuran-based antidiarrheal agent that effectively suppresses the activation of cellular STAT1/3/5 transcription activity with IC50 of 3 μM against IL-6-induced STAT3 activation in U3A cells.

S8197New

APTSTAT3-9R

APTSTAT3-9R is a specific STAT3-binding peptide with addition of a cell-penetrating motif. The treatment of APTSTAT3-9R in various types of cancer cells blocks STAT3 phosphorylation and reduces expression of STAT targets.

S7951New

STA-21

STA-21 is a selective STAT3 inhibitor.

S7337

SH-4-54

SH-4-54 is a potent STAT inhibitor with KD of 300 nM and 464 nM for STAT3 and STAT5, respectively.

S7977

Napabucasin

Napabucasin is an orally available Stat3 and cancer cell stemness inhibitor.

S2285

Cryptotanshinone

Cryptotanshinone is a STAT3 inhibitor with IC50 of 4.6 μM in a cell-free assay, strongly inhibits phosphorylation of STAT3 Tyr705, with a small effect on STAT3 Ser727, but none against STAT1 nor STAT5.

S7501

HO-3867

HO-3867, an analog of curcumin, is a selective STAT3 inhibitor.
