One of a class of naturally occurring alkaloids with a structure based on that of ergoline.
| Member | Definition | Role |
|---|
| ergoline | An indole alkaloid whose structural skeleton is found in many naturally occurring and synthetic ergolines which are known to bind to neurotransmitter receptors, such as dopamine, noradrenaline and serotonin receptors and function as unselective agonists or antagonists at these receptors. | ergoline |
| lysergamide | An ergoline alkaloid comprising ergoline lacking hydrogens at positions 9 and 10 and also having a methyl group attached to the piperidine nitrogen. | lysergamide |
| lysergic acid diethylamide | An ergoline alkaloid arising from formal condensation of lysergic acid with diethylamine. | lysergic acid diethylamide |
| lysergol | An alkaloid of the ergoline family that occurs as a minor constituent in some species of fungi and in the morning glory family of plants. Its structure is that of ergoline with a methyl group at N-6 and a beta-hydroxymethyl substituent at C-8. | lysergol |
| metergoline | An ergoline alkaloid that is the N-benzyloxycarbonyl derivative of lysergamine. A 5-HT2 antagonist. Also 5-HT1 antagonist and 5-HT1D ligand. Has moderate affinity for 5-HT6 and high affinity for 5-HT7. | metergoline |
| methergine | | N-(1-hydroxybutan-2-yl)-7-methyl-6,6a,8,9-tetrahydro-4H-indolo[4,3-fg]quinoline-9-carboxamide |
| methylergonovine | | (6aR,9R)-N-[(2S)-1-hydroxybutan-2-yl]-7-methyl-6,6a,8,9-tetrahydro-4H-indolo[4,3-fg]quinoline-9-carboxamide |
| methylergonovine maleate | | Methylergonovine Maleate |
| methysergide | | (6aR,9R)-N-[(2S)-1-hydroxybutan-2-yl]-4,7-dimethyl-6,6a,8,9-tetrahydroindolo[4,3-fg]quinoline-9-carboxamide |
| methysergide maleate | | Methysergide maleate |
| sansert | | N-(1-hydroxybutan-2-yl)-4,7-dimethyl-6,6a,8,9-tetrahydroindolo[4,3-fg]quinoline-9-carboxamide |
