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.

Previous studies suggest that noradrenaline may regulate serotonergic (5-HT) neurotransmission at the serotonin cell body and noradrenaline nerve terminal. Using microdialysis coupled to HPLC, we investigated the effects of alpha1-adrenoceptor manipulation on extracellular serotonin levels - in the ventral hippocampus

We have demonstrated previously that [3H]idazoxan, besides being able to bind to alpha 2-adrenergic receptors, may also bind to a nonadrenergic idazoxan-receptor site with high affinity. The idazoxan receptor is tightly bound to cellular membranes, and we have now developed

The median preoptic nucleus (MnPO) in the lamina terminalis receives a prominent catecholaminergic innervation from the dorsomedial and ventrolateral medulla. The present investigation used whole cell patch-clamp recordings in rat brain slice preparations to evaluate the hypothesis that presynaptic adrenoceptors

Although melanin production is a key self-defense mechanism against ultraviolet radiation (UVR)-induced skin damage, uneven or excessive deposition of melanin causes hyperpigmentary disorders. Currently available whitening agents are unsatisfactory because of issues with efficacy and safety. To develop more effective
