Quinate is an antiarrhythmic agent. Quinate is a potent, orally active, selective cytochrome P450db inhibitor. Quinate is also a K+ channel blocker with an IC50 of 19.9 μM. Quinate can be used for malaria research[1][2][3].

Description	Quinate is an antiarrhythmic agent. Quinate is a potent, orally active, selective cytochrome P450db inhibitor. Quinate is also a K+ channel blocker with an IC50 of 19.9 μM. Quinate can be used for malaria research[1][2][3].

In Vitro	Quinidine is an anti-arrythmic drug which affects ionic currents in heart muscle and which has also been shown to be a potent blocker of several classes of K+ channel in a variety of cell types[1]. Bath application of quinidine causes a dose-dependent reduction of the peak amplitude of Ik. The Kd for blockade of Ik at 0 mV is estimated to be 41 μM[1]. Quinidine elicits a dose-dependent increase of the rate of the decay of Ik and this effect is enhanced by membrane depolarization. Quinidine also causes a 5 mV hyperpolarizing shift of the steady-state inactivation curve and increases the half-time for recovery from inactivation. Quinidine does not affect the onset of inactivation measured at -30 mV[1].
In Vivo	Quinidine sulfate is rapidly absorbed, with peak plasma concentrations 60-90 min after an oral dose. Other salts (gluconate, polygalacturonate) are more slowly absorbed, with lower peak concentrations[2]. Quinidine is approximately 70-90 % bound to plasma proteins. It undergoes hepatic oxidative metabolism to form an N-oxide, a 3-hydroxy form, an O-demethyl form and 2'-quinidinone[2]. Quinidine inhibits metabolism of amphetamine in rats. Quinidine pretreatment results in a significant decrease in the excretion of p-hydroxyamphetamine at 24 and 48 h to 7.2 and 24.1% of the vehicle-control levels, respectively, accompanied by a significant increase in amphetamine excretion between 24 and 48 h to 542% of the control[3].
