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 which causes a specific depletion of STAT1 protein (and mRNA) but not of other STATs. Also 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 STAT3 with IC50 of 0.7 μM in a cell-free assay. Niclosamide selectively inhibited the phosphorylation of STAT3 and had no obvious inhibition against the activation of other homologues (e.g., STAT1 and STAT5).

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.

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.

S8685

AS1517499

AS1517499 is a novel and potent STAT6 inhibitor with an IC50 value of 21 nM.

S7977

Napabucasin(BBI608)

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

S2265

Artesunate

Artesunate is a part of the artemisinin group of agents with an IC50 of < 5 μM for small cell lung carcinoma cell line H69. It is a potential inhibitor of STAT-3 and exhibits selective cytotoxicity of cancer cells over normal cells in vitro; A potent inhibitor of EXP1.

S7769

BP-1-102

BP-1-102 is a potent, orally bioavailable and selective STAT3 inhibitor, binds Stat3 with an affinity Kd of 504 nM and blocks Stat3-phospho-tyrosine (pTyr) peptide interactions and Stat3 activation at 4-6.8 μM.

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.

S7923

SH5-07 (SH-5-07)

SH5-07 is a robust hydroxamic acid-based STAT3 inhibitor, which induce antitumor cell effects in vitro and antitumor response in vivo against human glioma and breast cancer models.

S7951

Ochromycinone (STA-21)

Ochromycinone (STA-21) is a selective STAT3 inhibitor.

S8561

HJC0152

HJC0152 is a signal transducer and activator of transcription 3 (STAT3) inhibitor with remarkably improved aqueous solubility.

S8197

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.

S8605

C188-9

C188-9 is a potent inhibitor of STAT3 that binds to STAT3 with high affinity (KD=4.7±0.4 nM). C188-9 is well tolerated in mice, shows good oral bioavailability, and is concentrated in tumors.

S7501

HO-3867

HO-3867, an analog of curcumin, is a selective STAT3 inhibitor that inhibits its phosphorylation, transcription, and DNA binding without affecting the expression of other active STATs.
