Chemical Name: (S)-(6-Methoxyquinolin-4-yl)((2R,4S,8R)- 8-vinylquinuclidin-2-yl)methanol hydrochloride
Biological ActivityQuinidine is a class IA antiarrythmic; reduces both Na+ and K+ channel currents, including INa, IKr and IKs. Prolongs QT and induces torsade de pointes (TdP).

Excellent for blocking organic cation transport at 50 uM in rat aorta. However also acts as non-competitive antagonist of alpha-1 adrenoceptors. This is evidenced by the fact it can block vasoconstrictor responses induced by the alpha-1 adrenoceptor agonist phenylephrine in a non-competitive manner.
Product was used on voltage gated potassium channels (Kv11.1 and Kv7.1) to understand blocking effect.
