Veratramine
Based on 1 publication(s) in Google Scholar
Veratramine (NSC17821; NSC23880) is an orally active inhibitor of the PI3K/Akt/mTOR signaling pathway and a SIGMAR1 modulator. Veratramine induces autophagic apoptosis of tumor cells, arrests the cell cycle at the G0/G1 phase, and inhibits epithelial-mesenchymal transition (EMT)-related proteins to reduce tumor migration. Veratramine reduces spinal cord and sciatic nerve pathological damage in a neuropathy model by inhibiting SIGMAR1 binding to NMDAR and phosphorylation of NMDAR Ser896. Veratramine has anti-tumor proliferation, apoptosis induction, anti-inflammatory and neuroprotective activities, and can be used in the study of cancers such as liver cancer and osteosarcoma, as well as diabetic peripheral neuropathy.

Biologische Aktivität
Veratramine (2.5-80 μM; 24-72 h) inhibits cell proliferation, migration and invasion, induces G0/G1 arrest and autophagic apoptosis, and downregulates proteins related to the PI3K/Akt/mTOR signaling pathway in human hepatoma HepG2 cell experiments[1].
Veratramine (30-50 μM; 24-48 h) inhibits cell viability, migration and invasion, induces apoptosis, and downregulates p-PI3K, p-Akt, and EMT-related proteins N-cadherin and vimentin in human osteosarcoma 143B and HOS cell experiments[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
