Stimulation of pre- and postsynaptic dopamine receptors by an ergoline and by a partial ergoline

Brain Research, 1981
The capacity of the ergoline, pergolide, and of the partial ergoline, LY 141865, to stimulate pre- and postsynaptic dopamine (DA) receptors was investigated. Binding studies have revealed that pergolide has a high affinity, while the partial ergoline, LY 141865, has a low affinity for the postsynaptic striatal DA receptors in vitro.

Ergoline and non-ergoline derivatives in the treatment of Parkinson’s disease

Journal of Neurology, 2006
There are a large variety of dopamine agonists available. Especially de novo patients are treated with dopamine agonists to avoid dyskinesia. Dopamine agonists can be subdivided into ergoline and non-ergoline derivatives. This distinction raises the question whether there are differences in the effects to treat symptoms, not only in the side effects ...

ChemInform Abstract: Electrophilic Substitution of Lithiated Ergolines.

ChemInform, 1988
Abstract Substitution of the ergoline derivative terguride 1 in the positions 2, 12 and 13 is effected by reaction of the respective bromo-ergolines with tert .-butyllithium and an electrophile in a regioselective manner.

Inhibition of Prolactin Secretion by Ergolines

Endocrinology, 1974
Peptide-containing ergot alkaloids and synthetic ergoline derivatives were administered to reserpine-treated male rats in order to evaluate their prolactin-inhibiting properties. Each compound was administered ip at a standard 50 ¼g/kg dose. The 9,10-dihydrogenated ergots, dihydroergocornine, and dihydroergocryptine were able to inhibit prolactin to ...

Ergolines as selective 5-HT1 agonists

Journal of Medicinal Chemistry, 1988
The synthesis and serotonin receptor subtype affinity of a series of ergolines are described. High selectivity for the 5-HT1 subtype was found with a number of 8-substituted (3 beta, 5 beta)-9,10-didehydro-6-methylergolines. The more potent and selective of these compounds increased the concentration of serotonin and decreased the concentration of 5 ...
