Endogenous acetylcholine-induced Na, K-ATPase activators and inhibitors

Effect of pyridine and quinoline N-oxides on microsomal Na,K-ATPase activity

“…Previously, we demonstrated that endogenous inhibitors and activators of the Na,K-ATPase activity exist in rat brain and liver [2,3] and showed that these agents are secreted under the action of neuromediators such as acetylcholine and noradrenaline (norepinephrine). In continuation of investigations into this direction, we have studied exogenous substances capable of modifying the activity of Na,K-ATPase.…”

“…The effect of compounds I -XIV on the activity of this enzyme was determined in cattle brain microsomes as described in [2,3].…”
