Fenoldopam is a selective D 1 receptor partial agonist that does not cross the blood-brain-barrier and is used intravenously in the treatment of hypertension. Dihydrexidine and adrogolide (ABT-431) (a prodrug of A-86929 with improved bioavailability) are the only selective, centrally active D 1-like receptor agonists that have been studied ...
They are all G protein-coupled receptors. D 1 - and D 5-receptors belong to the D 1-like family and the D 2-like family includes D 2, D 3 and D 4 receptors. [1] Dopamine agonists are primarily used in the treatment of the motor symptoms of Parkinson's disease, and to a lesser extent, in hyperprolactinemia and restless legs syndrome.
The D 1-like family receptors are coupled to the G protein G sα. D 1 is also coupled to G olf. G sα subsequently activates adenylyl cyclase, increasing the intracellular concentration of the second messenger cyclic adenosine monophosphate (cAMP). [8] D 1 is encoded by the Dopamine receptor D 1 gene . D 5 is encoded by the Dopamine receptor D ...

In contrast to dopamine, fenoldopam is a selective D 1 receptor agonist with no effect on beta adrenoceptors, although there is evidence that it may have some alpha-1 [8] and alpha-2 adrenoceptor antagonist activity. [6] D 1 receptor stimulation activates adenylyl cyclase and raises intracellular cyclic AMP, resulting in vasodilation of most ...
The D 1-like receptors are a subfamily of dopamine receptors that bind the endogenous neurotransmitter dopamine. [1] The D 1-like subfamily consists of two G protein–coupled receptors that are coupled to G s and mediate excitatory neurotransmission, of which include D 1 and D 5. [2]

A-68930 is a synthetic compound that acts as a selective dopamine receptor D 1 agonist. [1 ... SKF-82958 may be due to their differing effects on the related D 5 ...
