The aminoergolines SDZ 208-911 [N-[(8-alpha)-2,6-dimethylergoline-8-yl]-2,2- dimethylpropanamide] and SDZ 208-912 [N-[8-alpha)-2-chloro-6-methylergoline-8-yl]- 2,2-dimethylpropanamide] exhibit nonclassical, neuroleptic-like properties in rodents.

Journal of Pharmacology and Experimental Therapeutics, 1993
Serotonin-induced contraction in porcine coronary artery was studied in ring segments of coronary artery without endothelium. 5-hydroxytryptamine (5-HT), 5-methoxytryptamine (5-MeOT) and alpha-methyl-5-HT (alpha Me-5-HT) concentration-dependently ...

A Crystallographic Investigation of Ergolines
Structural Chemistry, 2002The X-ray crystal structures of three ergoline derivatives have been completed and are reported herein. These include mesulergine hydrochloride (III), pergolide methanesulfonate (IV), and dihydroergocriptine hydrate (V). These molecules show dopamine agonist activity at the D2 receptor.

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.

Ergoline derivatives: receptor affinity and selectivity
Il Farmaco, 1999Ergot comprises a group of indole alkaloids which are predominantly found in various species of the ascomycete Claviceps. In pharmacopoeias, the sclerotia of Claviceps purpurea (Fr.) Tulasne parasitizing on rye, Secale cereale L., are designed as ergot or Secale cornutum.

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.

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.

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.
