Dopamine Receptor
Dopamine Receptors are a class of G protein-coupled receptors that are prominent in the vertebrate central nervous system (CNS). The neurotransmitter dopamine is the primary endogenous ligand for dopamine receptors. Dopamine receptors are implicated in many neurological processes, including motivation, pleasure, cognition, memory, learning, and fine motor control, as well as modulation of neuroendocrine signaling. Abnormal dopamine receptor signaling and dopaminergic nerve function is implicated in several neuropsychiatric disorders. Thus, dopamine receptors are common neurologic drug targets; antipsychotics are often dopamine receptor antagonists while psychostimulants are typically indirect agonists of dopamine receptors. There are at least five subtypes of dopamine receptors, D1, D2, D3, D4, and D5. The D1 and D5 receptors are members of the D1-like family of dopamine receptors, whereas the D2, D3 and D4receptors are members of the D2-like family.

Dihydroergotamine
0 ImagesDihydroergotamine (DFN-19) is a blood-brain barrier-permeable semi-synthetic ergot alkaloid, acting as a full agonist of 5-HT1B/1D receptors (Ki values of 0.3 nM and 2.5 nM, respectively; functional IC50 values of 2 nM and 2.2 nM, respectively). Dihydroergotamine inhibits Forskolin (HY-15371)-stimulated cAMP accumulation, possesses α-adrenergic receptor antagonistic activity and weak dopaminergic agonistic activity. It mediates intracranial cerebrovascular contraction, inhibits the release of neuropeptides such as CGRP/substance P, and suppresses neurogenic inflammation by activating 5-HT1B/1D receptors in the trigeminovascular system. Dihydroergotamine binds to the catalytic site of Trypanosoma cruzi trypanothione reductase and exhibits trypanocidal activity in vitro. Dihydroergotamine can be used in studies related to migraine and trypanosome infections.
