Quinidine polygalacturonate
Based on 25 publication(s) in Google Scholar
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.

In Vitro
Quinidine (10 μM; 24 h) polygalacturonate potentiates Paclitaxel (HY-B0015)-induced cytotoxicity in P-gp-positive MES-SA/DX5 uterine sarcoma cells (reducing paclitaxel IC50 to 80.56 nM) but does not alter paclitaxel cytotoxicity in P-gp-negative MES-SA uterine sarcoma cells[1].
Quinidine (10 μM; 24 h) polygalacturonate significantly increases the sub-G1 apoptotic portion in paclitaxel-treated P-gp-positive MES-SA/DX5 uterine sarcoma cells, enhancing paclitaxel-induced apoptosis[1].
Quinidine inhibits the in vitro metabolism of Debrisoquine in rat liver microsomes, with lower potency than observed in human liver microsomes[3].
