JAK1/TYK2-IN-3 also shows selectively relative to JAK2 (IC50=140 nM) and JAK3 (IC50=362 nM). JAK1/TYK2-IN-3 shows anti-inflammatory effect by regulating the expression of related TYK2/JAK1-regulated genes, as well as the formation of Th1, Th2, and Th17 cells.

JAK-IN-19 is a potent JAK inhibitor (PBMC IFNγ pIC50=7.2 and HLF Eotaxin pIC50=7.7). JAK-IN-19 has good retentive properties in the lung via mitigating being metabolized by Aldehyde Oxidase (AO), with diminished VEGFR2 selectivity (VEGFR2 pIC50=7.0, Aurora B pIC50=5.8).

Tofacitinib Prodrug-1 is an effective and oral active prodrug to mitigate the systemic adverse effects of Tofacitinib. Tofacitinib Prodrug-1 can effectively attenuate the oxazolone-induced colitis in mice model with low toxicity. Tofacitinib Prodrug-1 is a potential drug candidate for the treatment of ulcerative colitis.

Danvatirsen is an antisense oligonucleotide targeting STAT3 with potential antitumor activity. Danvatirsen binds to STAT3 mRNA, thereby inhibiting translation of the transcript. Suppression of STAT3 expression induces tumor cell apoptosis and decreases tumor cell growth.

5,15-Diphenylporphyrin (5,15-DPP) is a selective STAT3-SH2 antagonist (IC50s of 0.28 µM and 10 µM for STAT3 and STAT1, respectively).

STAT3-IN-7, an aryl sulfonamido azetidine compound, is an orally active STAT3 inhibitor. STAT3-IN-7 has anticancer activities (WO2021016333A1, H182).

2-NP is a selective enhancer of STAT1 transcription. 2-NP can enhance the ability of IFN-γ to inhibit the proliferation of human breast cancer and fibrosarcoma cells.

Napabucasin (BBI-608) is a potent small-molecule inhibitor of STAT3 that has a broad spectrum of activity against stemness-high cancer cells (IC50=0.5-1.5 uM).

GDC-0339 (GDC0339) is a novel small molecule pan-Pim kinase inhibitor that was discovered as a potential treatment for multiple myeloma.

Flonoltinib maleate is a potent, highly selective, dual JAK2/FLT3 inhibitor with IC50 of 0.8, 1.4, and 15 nM for JAK2, JAK2V617F, and FLT3, respectively.

A novel small molecule SH2 domain-targeting STAT3 inhibitor with IC50/Kd of 7.3/5 nM; does not bind to the S636A, V637A, and E638A SH2D mutants; effectively inhibits STAT3 phosphorylation (pTyr705 and pSer727) and cancer cell proliferation, impairs mitochondrial function; shows potent activity tumor xenografts in mice; orally bioactive.
