Quinidine polygalacturonate
- CAS No.: 27555-34-6
- Formula:C26H34N2O9
- Molecular Weight:N/A
SMILES: O=C[C@H](O)[C@@H](O)[C@@H](O)[C@H](O)C(O)=O.O[C@H]([C@]1([H])[N@@]2C[C@H](C=C)[C@@H](CC2)C1)C3=CC=NC4=CC=C(OC)C=C34.[n].[n]
Biological Activity: Quinidine polygalacturonate is an orally active antiarrhythmic agent. Quinidine polygalacturonate reduces the expression level of P-gp, inhibits P-gp-mediated efflux, increases the intracellular accumulation of P-gp substrates, induces PARP cleavage and Caspase-3 activation, and elevates the proportion of Apoptotic cells at the sub-G1 phase. Quinidine polygalacturonate exerts sustained block and open-channel block effects on IK(f). Quinidine polygalacturonate alters the urinary metabolic ratio of Amphetamine, modulates the Pentylenetetrazol-induced seizure threshold, and regulates the anticonvulsant effect of Dextromethorphan. Quinidine polygalacturonate can be used in studies related to uterine sarcoma and seizures[1][2][3][4].
