Declopramide
Declopramide (3-Chloroprocainamide) is an orally active, blood-brain barrier-permeable IκBβ/NF-κB inhibitor and chemosensitizer. Declopramide exhibits affinity for rabbit 5-HT3 receptors (5-HT3R) with a Ki value of 3.2 μM. Declopramide inhibits IκBβ degradation, blocks NFκB activation, and induces rapid apoptosis and DNA strand breaks in cancer cells. Declopramide enhances the cytotoxicity induced by Cisplatin (HY-17394) and is also metabolically converted to N-acetyl declopramide. Declopramide can be used in the research of tumors such as brain astrocytoma.

体外実験
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:murine pre-B-cell line 70Z/3
-
Concentration:250 µM; 500 µM; 1000 µM; 500 µM (with 1 h ZVADfmk pretreatment)
-
Incubation Time:20 h; 17 h (with 1 h ZVADfmk pretreatment)
-
Result:Induced a dose-dependent increase in early apoptosis (Annexin V-positive/7AAD-negative cells) and corresponding decrease in viable (7AAD-negative) cells in 70Z/3 cells.
Reduced viable cell percentage and increased early apoptotic cell percentage relative to untreated cells at 500 µM.
Significantly reduced declopramide-induced apoptosis when caspase inhibitor ZVADfmk was used, measured via both 7AAD and Annexin V staining.
