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.

S1014

Bosutinib (SKI-606)

Bosutinib (SKI-606) is a novel, dual Src/Abl inhibitor with IC50 of 1.2 nM and 1 nM in cell-free assays, respectively. Bosutinib also effectively decreases the activity of PI3K/AKT/mTOR, MAPK/ERK and JAK/STAT3 signaling pathways by blocking the phosphorylation levels of p-ERK, p-S6, and p-STAT3. Bosutinib promotes autophagy.

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. Fludarabine induces apoptosis.

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. Stattic induces apoptosis.

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).

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)

S9015

Homoharringtonine

Homoharringtonine, a plant alkaloid with antitumor properties, inhibits protein translation by preventing the initial elongation step of protein synthesis via an interaction with the ribosomal A-site. Homoharringtonine reversiblely inhibits IL-6-induced STAT3 Tyrosine 705 phosphorylation and reduced anti-apoptotic proteins expression.

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.

S3810

Scutellarin

Scutellarin, the major active principal flavonoids extracted from the Chinese herbal medicines Scutellaria baicalensis and Erigeron breviscapus (Vant.) Hand-Mazz, has many pharmacological effects, such as antioxidant, antitumor, antiviral, and antiinflammatory activities. Scutellarin, an active flavone isolated from Scutellaria baicalensis, can down-regulates the STAT3/Girdin/Akt signaling in HCC cells, and inhibits RANKL-mediated MAPK and NF-κB signaling pathway in osteoclasts.

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.
