3-O-Methylgallic acid (3,4-Dihydroxy-5-methoxybenzoic acid) reduces cell proliferation in Caco-2 cells (IC50 = 24.1 μM) more effectively than anthocyanins and may offer protection against colon cancer after its formation in the gut.

[1] Osunprotafib (ABBV-CLS-484) stimulates the tumor microenvironment and promotes natural killer cell and CD8 T cell function and enhances T cell anti-tumor immunity by enhancing JAK-STAT signaling and reducing T cell dysfunction. [2]

Beclometasone dipropionate (Vancenase) is the dipropionate ester of a synthetic glucocorticoid with anti-inflammatory and immunomodulating properties. After cell surface receptor attachment and cell entry, beclomethasone enters the nucleus where it binds to and activates specific nuclear receptors, resulting in an altered gene expression and inhibition of proinflammatory cytokine production.

Momelotinib (LM-1149) is an orally bioavailable small-molecule inhibitor of Janus kinases 1 and 2 (JAK1 2) with IC50 of 11 nM 18 nM. JAK1 2 inhibitor CYT387 competes with JAK1 2 for ATP binding, which may result in inhibition of JAK1 2 activation, inhibition of the JAK-STAT signaling pathway, and so the induction of apoptosis and a reduction of tumor cell proliferation in JAK1 2-expressing tumor cells.

Cryptotanshinone (Cryptotanshinon), a STAT3 inhibitor (IC50: 4.6 μM) in a cell-free assay, strongly inhibits phosphorylation of STAT3 Tyr705, with a little effect on STAT3 Ser727, but no inhibition for STAT1 nor STAT5.

TPCA-1 (TPCA1) is an effective and specific IKK-2 inhibitor (IC50: 17.9 nM); shows >22-fold selectivity over IKK-1 and >550-fold selectivity over others kinases and enzymes.

BP-1-102 is an orally active, effective, and specific STAT3 inhibitor that binds Stat3 (Kd: 504 nM), blocks Stat3-phosphotyrosine (pTyr) peptide interactions and Stat3 activation (4-6.8 μM), and selectively inhibits the migration, survival, growth, and invasion of Stat3-dependent tumor cells. The BP-1-102-mediated inhibition of aberrantly active Stat3 in tumor cells suppresses the expression of [c-Myc, Bcl-xL, Cyclin D1, Survivin, and VEGF].

STAT5-IN-1 (STAT5 Inhibitor) is a cell-permeable inhibitor which suppresses Stat5 via binding to the SH2 domain.

STAT3-IN-1 selective and orally active inhibitor of STAT3(in HT29 and MDA-MB 231 cells, with IC50 values of 1.82 μM and 2.14 μM , respectively), induces tumor apoptosis.

MK256 is a novel CDK8 inhibitor that demonstrates potent antitumor activity against AML by inhibiting the STAT pathway. It induces differentiation and maturation while inhibiting proliferation in AML cell lines. MK256 decreases the phosphorylation of STAT1(S727) and STAT5(S726) and reduces mRNA expression of MCL-1 and CCL2 in these cells. Its efficacy is validated in the MOLM-14 xenograft model, showing phosphorylation inhibition of STAT1(S727) and STAT5(S726) post-treatment. Pharmacokinetic studies in the MOLM-14 model reveal a dose-dependent inhibition of the STAT pathway. Both in vitro and in vivo studies confirm that MK256 effectively downregulates the STAT pathway.

DualCathepsinL JAK-IN-1 (Compound A8) serves as a dual inhibitor of Cathepsin L (CTSL) and JAK, exhibiting IC50 values of 0.68 μM for CTSL and 337.1 nM, 5.251 nM, 27.29 nM, and 172.6 nM for JAK1 2 3 and TYK2, respectively. This compound effectively prevents the activation of MAPK, NF-κB, and JAK STAT signaling pathways, leading to significant anti-inflammatory therapeutic effects. DualCathepsinL JAK-IN-1 is applicable in research on acute lung injury (ALI).

Compound SC-1 is a a derivative of the multiple tyrosine kinase inhibitor sorafenib. Compound SC-1 potently inhibits the phosphorylation of STAT3 by blocking STAT3 phosphorylation and activation, and induces apoptosis in hepatocellular carcinoma cell lines[1].

Stafib-1 is a selective inhibitor of STAT5β targeting SH2 domain with an IC50 of 154 nM and a Ki of 44 nM.

Allylpyrocatechol is an antioxidant. Allylpyrocatechol attenuates collagen-induced arthritis via attenuation of oxidative stress secondary to modulation of the MAPK, JAK/STAT, and Nrf2/HO-1 pathways.

BRD0476 is a suppressor of pancreatic β-cell apoptosis. BRD0476 inhibits interferon-gamma (IFN-γ)-induced Janus kinase 2 (JAK2) and signal transducer and activation of transcription 1 (STAT1) signaling to promote β-cell survival. BRD0476 inhibits JAK-STAT

ζ-Stat (NSC37044), a specific and atypical inhibitor of PKC-ζ with an IC50 of 5 μM, demonstrates the ability to inhibit proliferation and induce apoptosis in melanoma cell lines, exhibiting antitumor activity in vitro[1][2].

Mollugin (Rubimaillin) may be a JAK2 inhibitor and inhibits LPS-induced inflammatory responses by blocking the activation of the JAK-STAT pathway. Mollugin as a candidate for a chemotherapeutic agent in OSCCs via the upregulation of the HO-1 and Nrf2 pathways and the downregulation of NF- κ B. Mollugin may be a novel therapeutic candidate for bone loss-associated disorders including osteoporosis, rheumatoid arthritis, and periodontitis. Also, it has anticancer efficacy, can modulate the HER2 pathway in HER2-overexpressing Y cells with a potential role in the treatment and prevention of human breast and ovarian Y with HER2 overexpression.

Lipid-derived lipoxins are produced at the site of vascular and mucosal inflammation where they down-regulate polymorphonuclear leukocyte recruitment and function. 15(R)-Lipoxin A4 (15(R)-LXA4) is derived from the aspirin-triggered formation of 15(R)-HETE from arachidonic acid. [1] [2] 15(R)-LXA4 inhibits LTB4-induced chemotaxis, adherence, and transmigration of neutrophils with twice the potency of LXA4 demonstrating activity in the nM range.[2] [3] The anti-inflammatory effects of aspirin may be ascribed in part to the ability of 15(R)-LXA4 to regulate leukocyte function.[4] 15(R)-LXA4 is reported to promote resolution of inflammation in LPS-treated stromal cells derived from intermediate-stage diseased supraspinatus tendons as evidenced by increased expression of the STAT-6 pathway target genes, ALOX15 and CD206.[5]
