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

Although G protein-coupled receptors are often categorized in terms of their primary coupling to a given type of Gα protein subunit, it is now well established that many show promiscuous coupling and activate multiple signaling pathways. Furthermore, some agonists selectively

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
