Gene Information

Application

Cirazoline hydrochloride has been used to activate the α1-noradrenergic receptors and to study the inhibitory effect of neurokinin1 (NK1) antagonists on respiratory activity using the brainstem transverse slice.

Biochem/physiol Actions

Cirazoline is a selective α1-adrenoceptor agonist and also a non-selective ligand for the imidazoline binding site. Cirazoline dereases spatial working memory performance in aged monkeys.

Features and Benefits

Clonidine and related drugs not only interact with alpha 2-adrenoceptors but also recognise non-adrenoceptor sites in the brain. The involvement of these imidazoline-preferring receptors in the regulation of the activity of locus coeruleus noradrenergic neurones (NA-LC) was investigated after inactivation

All neuronal networks are modulated by multiple neuropeptides and biogenic amines. Yet, few studies investigate how different modulators interact to regulate network activity. Here we explored the state-dependent functional interactions between three excitatory neuromodulators acting on neurokinin1 (NK1), alpha1 noradrenergic

The alpha-1 adrenergic agonist, cirazoline, was examined for effects on spatial working memory performance in aged rhesus monkeys. Cirazoline has additional high affinity for imidazoline receptors and has good brain penetrance when administered systemically. Spatial working memory was assessed using
