Leptomycin B (LMB) is a potent inhibitor of the nuclear export of proteins and is a potent antifungal antibiotic blocking the eukaryotic cell cycle. Leptomycin B inactivates CRM1 exportin 1 by covalent modification at a cysteine residue.

3,5,6,7,8,3',4'-Heptemthoxyflavone exhibits neuroprotective, chemopreventive, anti-allergic, anti-inflammatory, immunomodulatory, anti-aging, and photoprotective effects; it inhibits collagenase activity, induces type I procollagen synthesis in HDFn cells, and combats nitric oxide (NO) carcinogenesis.

Isoviolanthin reduces the migratory and invasive capacities of TGF-β1-treated HCC cells without cytotoxic effects on normal live cells and has potential as a therapeutic agent for the treatment of advanced-stage metastatic HCC. Isoviolanthin is a flavonoid glycoside extracted from the leaves of Dendrobium Officinale.

1. Pristimerin (Celastrol methyl ester) has anticancer activity , treatment with Pristimerin may be a potential strategy for the suppression of hypoxia-induced metastasis through the reversal of hypoxia-induced stem cell characteristics and EMT in cancer cells. 2. Pristimerin down-regulates the expression of pro-inflammatory mediators through blocking of NF-κB activation by inhibiting interconnected ROS/IKK/NF-κB signaling pathways, can effectively inhibit both arthritic inflammation and cartilage and bone damage in the joints.

Soyasaponin Ac can decrease the drug resistance via EMT pathway and weaken the migration ability of ovarian cancer cells.

Bisabosqual A is a potent asparagine synthetase (ASNS) inhibitor with an IC 50 of 10.7 μM, capable of covalently modifying the K556 site of the ASNS protein. It induces oxidative stress and apoptosis, while inhibiting autophagy, cell migration, and epithelial-mesenchymal transition (EMT), thereby slowing cancer cell development [1].

Argyrin F is a cyclopeptide with antitumor properties. It inhibits cell proliferation, migration, invasion, and colony formation by partially inducing apoptosis (apoptosis) and epithelial-mesenchymal transition (EMT). Argyrin F stabilizes p27kip, upregulates p21waf1 cip1, and reduces COX2. Argyrin F is applicable for research in pancreatic ductal adenocarcinoma (PDAC).
