Application

ARC 239 is a potent α-adrenoceptor blocking drug, competitively antagonizing pressor responses to adrenaline and inhibiting pressor responses to noradrenaline, phenylephrine, tyramine, and dimethylphenylpiperazinium.

Biochem/physiol Actions

ARC 239 is a selective α-2B adrenergic blocker. Although ARC-239, like prazosin, also has some alpha-1 antagonist activity, it is used most commomly to differentiate alpha-2A/D from alpha-2B and alpha-2C subtypes rather than for any alpha-1 inhibition..

The presynaptic modulation of [3H]-noradrenaline (NA) release from rat kidney cortex slices, a method used for the first time, was investigated. Rat kidney cortex slices were loaded with [3H]-NA and the release of radioactivity at rest and in response to

Exogenous pyrogens, e.g., bacterial lipopolysaccharides (LPS), are thought to stimulate macrophages to release endogenous pyrogens, e.g., TNF alpha, IL-1 beta, and IL-6, which act in the hypothalamus to produce fever. We studied the effect of different alpha 1- and alpha

The profile of [3H]RX821002 (2-methoxy idazoxan) binding to alpha2-adrenoceptor subtypes in rat kidney membranes was evaluated in controls and after chronic treatment with desipramine (10 mg/kg, i.p., every 12 h, 7 days) or clorgyline (2 mg/kg, i.p., every 24 h

The subtype determination of auto- and hetero-alpha 2-adrenoceptors modulating the synthesis of noradrenaline (NA) and serotonin (5-HT), respectively, was assessed using the accumulation of 3,4-dihydroxyphenylalanine (dopa) and 5-hydroxytryptophan (5-HTP) after decarboxylase inhibition as a measure of the rate of tyrosine

The rat rostral raphé nuclei receive catecholaminergic innervation from the locus coeruleus and other areas. In the present study, we investigated noradrenergic modulation of 5-HT release in rat dorsal and median raphé nuclei (DRN and MRN) slices (350 microm thick)
