Gene Information

General description

Linopiridine is a class of drugs that activates the nervous system and enhances the acetylcholine (Ach) in the brain. It can be prepared by reacting oxiindole with 4-picolyl chloride hydrochloride in the presence of a KF-Al2O3 catalyst.

Biochem/physiol Actions

Stimulates release of acetylcholine and other neurotransmitters; cognitive enhancer.

The M-current (current through Kv7 channels) is a low-threshold noninactivating potassium current that is suppressed by muscarinic agonists. Recent studies have shown its role in spike burst generation and intrinsic subthreshold theta resonance, both of which are important for memory

KCNQ channels have been identified in arterial smooth muscle. However, their role in vasoregulation and chronic vascular diseases remains elusive. We tested the hypothesis that KCNQ channels contribute to periadventitial vasoregulation in peripheral skeletal muscle arteries by perivascular adipose tissue

While the synaptic mechanisms involved in the generation of in vitro network oscillations have been widely studied, little is known about the importance of voltage-gated currents during such activity. Here we study the role of the M-current (I(M)) in the

Age-related hearing loss (ARHL) is associated with the loss of inner hair cell (IHC) ribbon synapses, lower hearing sensitivity and decreased ability to understand speech, especially in a noisy environment. Little is known about the age-related physiological and morphological changes
