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.

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

Agonism at 5-HT2B receptors is not a class effect of the ergolines.

European Journal of Pharmacology, 2005
Restrictive cardiac valvulopathies observed in Parkinson patients treated with the ergoline dopamine agonist pergolide have recently been associated with the agonist efficacy of the drug at 5-hydroxytryptamine2B (5-HT2B) receptors. To evaluate whether agonism at 5-HT2B receptors is a phenomenon of the class of the ergolines, we studied 5-HT2B receptor ...

Ergoline derivatives—VIII

Tetrahedron, 1965
Abstract The NH region of the IR spectra of lysergamides and dihydrolysergamides are reported, discussed and the bands assigned. Axial and equatorial amides are clearly distinguishable, the former present between the amide hydrogen and the tertiary nitrogen atom an intramolecular hydrogen bond which can very in strength.

Differential ergoline and ergopeptine binding to 5-hydroxytryptamine2A receptors: ergolines require an aromatic residue at position 340 for high affinity binding.

Molecular Pharmacology, 1995
In this paper we show that a highly conserved aromatic residue, phenylalanine at the 340-position, is essential for ergoline binding to 5-hydroxytryptamine2A receptors. We hypothesized that F340 was essential for a specific aromatic-aromatic interaction (e.g., pi-pi or hydrophobic) between the phenyl moiety of F340 and the aromatic ring of the ergoline

On the alleged electrochemical methoxylation of ergolines

Tetrahedron Letters, 1983
Abstract The products obtained by controlled potential electrolysis of ergolines (1) in 0.5N KOH-MeOH previously described as 2-methoxy derivatives (2) are actually the 1-hydroxy methyl ergolines (3).
