Product Description

  • Multifunctional anticancer compound. Amplifies the cellular antioxidant and/or detoxification system, suppresses inflammatory pathways, selectively inhibits tumor cell proliferation and induces apoptosis, suppresses tumor angiogenesis, blocks epithelial-to-mesenchymal transition (EMT), tumor invasion and metastasis, alters tumor cell metabolism, induces immunomodulation and downregulates cancer stem cells targets.
  • Sensitizes resistant cancer cells to existing chemotherapeutic agents.
  • Antioxidant. Induces cytoprotective enzymes (Nrf2-dependent as well), including SOD, HO-1 (heme oxygenase-1), catalase, glutathione peroxidise, glutathione s-transferase and NQO1.
  • Anti-inflammatory agent. Inhibits COX-2 and iNOS expression (at protein and mRNA level) and PGE2 production. Prevents NF-κB activation by inhibiting activation of IKKβ. Inhibits Helicobacter pylori-induced IL-1β production by regulating NF-κB and directly inhibiting NLRP3 inflammasome activation.
  • Antiproliferative agent. Induces G2/M phase cell cycle arrest, targeting CDKs. Shown to modulate STAT3, Bcl2, Notch receptors, Akt, Hsp90, EGFR, HER2 and PCNA.
  • Disrupts the organization of microtubules and actin/microfilament. Stimulates F-actin cross-linking.
  • Induces tumor cell apoptosis. Shown to induce ROS production. Activates mitochondrial apoptosis pathway through Bcl-2 downregulation and Bax upregulation. Shown to induce p53-dependent pathways and ER-stress. Activates the tumor suppressor protein PAR-4. Directly or indirectly inhibits selected other kinases, such  MAPK or STAT3. Shown to inhibit hedgehog signalling pathway.
  • Described to be an autophagy inducer and inhibitor.
  • Potent inhibitor of the 20S proteasome β5 subunit chymotrypsin-like activity.
  • Potent angiogenesis inhibitor by modulating VEGF. Antimigratory, antiinvasive and antimetastatic compound. Targets TGF-β, vimentin, MMPs and Notch receptors.
  • Inhibits cancer stem cells targets, including aldehyde dehydrogenase 1 (ALDH1) activity. Alters cell line-specific the mRNA expression of cancer stem cell markers, such as Oct4, SOX-2, and Nanog.
  • Reported to induce neuronal regeneration.
  • Antidiabetic compound. Potent Leptin sensitizer, acting similar to Celastrol (Prod. No. AG-CN2-0460).
