ChemInform Abstract: Electrophilic Substitution of Lithiated Ergolines.
ChemInform, 1988Abstract 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, 1974Peptide-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, 1988The 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 ...

On the alleged electrochemical methoxylation of ergolines
Tetrahedron Letters, 1983Abstract 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).

Nidation Inhibition by Simple Ergoline Derivatives
Journal of Pharmaceutical Sciences, 1975The ability of four ergoline-type compounds (elymoclavine, its O-benzoate and O-carbamate, and N-methyl-6,7-secoelymoclavine) to inhibit nidation in rats was determined and found to parallel their prolactin-inhibiting activity.

2-Acylated derivatives of ergoline
Collection of Czechoslovak Chemical Communications, 1982Reactions of ergoline derivatives Ia-VIIa with anhydrides of low-molecular-weight aliphatic acids, catalysed by boron trifluoride etherate, gave 2-acylated derivatives Ib-Id, IIb-IId, IIIb-Vb, or 1,2-diacylated derivatives VIb and VIIb. The compound IIb exhibited a hypotensive effect.

1,2-Fused derivatives of ergoline
Collection of Czechoslovak Chemical Communications, 19822-Formylergoline derivatives I and II were condensed with methyl isonitrilacetate in the presence of a base. Depending on the nature of this base, the main products of the reaction were either derivatives of pyrimido[1,6-a]ergoline, III and IV, or derivatives of 2-formylamino-3-oxo-3H-pyrrolo[1,2-a]ergoline, V and VI.
