The most prevalent catecholamine in the brain is dopamine (DA). It is generally recognized that DA plays a crucial role in the central nervous system's (CNS) control of a variety of physiological processes. Parkinson's disease, Tourette's syndrome, schizophrenia, attention deficit hyperactivity disorder (ADHD), and the development of pituitary tumors have all been connected to dopaminergic system dysregulation.
Creative Biolabs can provide a wide variety of dopamine family related assays and products to meet the needs of drug discovery:
Overview of Dopamine Family
Dopamine is an adrenergic substance that acts on receptors D1 to D5 to produce a variety of different effects. The D1-like family (D1, D4) and the D2-like family are two groups that make up the receptors (D2, D3, D5). Neurotransmitter dopamine is produced in the hypothalamus, substantia nigra, pars compacta, and ventral tegmental area (VTA). Axons from these regions travel to different regions of the brain along four main pathways.
- D1-like family
D1-like receptors bind to Gαs/olf and increase adenylate cyclase activity, which in turn triggers the activation of PKA and other signaling molecules. Although Gαolf appears to promote adenylate cyclase activity and is highly expressed in dopaminergic regions like the neostriatum, Gαs also appears to mediate D1-like receptor activation. Moreover, D1-like receptors can either directly or indirectly mediate signaling at a number of voltage-gated ion channels, in addition to NMDA and GABAA receptors, by acting on DARPP-32, the MAPK pathway, and other kinases and phosphatases.
- D2-like family
The Gαi/o class of G proteins, which are deactivated by pertussis toxin-catalyzed ADP-ribosylation, are a key modulator of D2-like signaling. Adenylate cyclase and cAMP buildup are inhibited by G proteins of the Gαi/o class. In most clonal and in situ cells, adenylate cyclase is inhibited by both D2 and D4 receptors. Compared to other D2-like receptors, D3 dopamine receptors have a tendency to bind agonists with a higher affinity. Additionally, it has been proposed that the GTP-insensitive way in which D3 dopamine receptors bind agonists is due to a receptor conformation that has a high affinity for agonists regardless of interactions with G proteins.
Dopamine Family Drug Discovery
Although the positive symptoms of schizophrenia are often well-managed by current APDs, unwelcome side effects and a lack of efficacy in managing the negative and cognitive symptoms have brought attention to the need for new and enhanced APDs. The hunt for functionally selective drugs should also look at other signaling pathways that the D1 and D2 receptors stimulate. The dopamine receptor system is the main target for APDs, but pinpointing the dopamine-mediated signaling pathways responsible for the unique symptoms of schizophrenia will aid in concentrating drug discovery and development efforts.
