Tetramethylcurcumin is a novel curcumin analog, is an effective inhibitors of STAT3 phosphorylation, DNA binding activity, and transactivation in vitro.it also inhibits colony formation in soft agar, cell invasion, and exhibit synergy with the anti-cancer drug doxorubicin against breast cancer cells.

Brevilin A is a sesquiterpene lactone isolated from Centipeda minima, inhibits janus kinase activity and blocks STAT3 signaling in cancer cells with anti-tumor activity. Brevilin A is a selective inhibitor of JAK-STAT signal pathway by attenuating the JAKs activity and blocking STAT3 signaling (IC50 = 10.6 μM) in Cancer Cells.Brevilin A induces apoptosis and autophagy via mitochondrial pathway and PI3K AKT mTOR inactivation in colon adenocarcinoma cell CT26.antitumour

Ginsenoside Rk1 is a component created by processing the ginseng plant at high temperatures. Ginsenoside Rk1 has an anti-inflammatory effect, suppresses the activation of Jak2/Stat3 signaling pathway and NF-κB. It also has an anti-tumor effect.

1. Atractylenolide-I has an anti-inflammatory effect by inhibiting TNF-α and IL-6 production; ameliorates sepsis syndrome, liver and kidney functions by reduction of pro-inflammatory cytokines and LPS. 2. Atractylenolide-I significantly sensitizes the res

1. Curculigoside (Curculigoside A) can prevent bone loss , improve osteogenesis and inhibit osteoclastogenesis of hAFSCs, suggesting its potential use to regulate hAFSC osteogenic differentiation for treating bone disorders. 2. Curculigoside can promote calcium deposition and increase the levels of ALP and Runx2 in osteoblasts under oxidative stress via anti-oxidative character. 3. Curculigoside possesses potent antioxidant properties against oxidative stress insults. can protect endothelial cells against oxidative injury induced by H2O2, suggesting that this compound may constitute a promising intervention against cardiovascular disorders.

Protosappanin A (PTA) has anti-oxidative/nitrative activities on brain immune and neuroinflammation through regulation of CD14/TLR4-dependent IKK/IκB/NF-κB inflammation signal pathway; it exerts anti-neuroinflammatory effect by inhibiting JAK2-STAT3 pathway in lipopolysaccharide-induced BV2 microglia. Protosappanin A induces immunosuppression of rats heart transplantation targeting T cells in grafts via NF-kappaB pathway. Protosappanin A and protosappanin B have antimicrobial activity, they show both alone activities and resistance reversal effects of amikacin and gentamicin against MRSA. Protosappanin A shows strong effect against HIV-1 IN with an IC50 value of 12.6 uM.

Cucurbitacin I (JSI-124), a natural compound, is a selective inhibitor of JAK2 STAT3 with anti-cancer activity.
