Preparation and Characterization of Ergoline Thiazolidinones and an Ergoline Imidazolidinone

Archiv der Pharmazie, 1986
AbstractThe preparation of the ergoline thiazolidinones 2,3 and the ergoline imidazolidinone 5 is described. The 13C‐ and 15N‐NMR spectra of the 15N‐labelled compounds 15N‐ 2a and 15N‐3a allow the distinction of the two isomers.

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 ...

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.

Ergoline derivatives: receptor affinity and selectivity

Il Farmaco, 1999
Ergot 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.

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 ...

Nidation Inhibition by Simple Ergoline Derivatives

Journal of Pharmaceutical Sciences, 1975
The 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.

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 Alkaloids in Tropical Wood Roses

Science, 1965
Extracts of Argyreia nervosa , a tropical wood rose, contain appreciable quantities of ergoline alkaloids tentatively identified as ergine isoergine, and penniclavine together with related substances.
