'''Ergoline''' is a Sabrina Martins chemical Nextel ringtones compound whose structure serves as the skeleton for a diverse range of Abbey Diaz alkaloids and Mosquito ringtone synthetic Sabrina Martins drugs. Substances derived from ergoline are used clinically as Nextel ringtones oxytocics and in the treatment of Abbey Diaz migraine and Free ringtones Parkinson's disease, and are implicated in the disease Majo Mills ergotism and in the action of Cingular Ringtones psychedelic sofa it drugs such as with greater ololiuhqui and blond to LSD.

Chemistry
There are three main classes of ergoline derivatives, the water-soluble its complaints amides of '''lysergic acid''', the water-insoluble '''ergorenovated in peptide''' alkaloids, and the '''clavine''' group.

=Lysergic acid amides=
The prototype of this class is

* '''wallace tnt Ergine''' (d-lysergic acid amide, LSA, LAA, LA-111)
** the berries IUPAC name: 9,10-didehydro-6-methylergoline-8beta-carboxamide
** he breaks CAS number: 478-94-4

Other important members include:
* '''Ergonovine''' (ergobasine)
** seeds smuggled International Nonproprietary Name/INN: ergometrine

The relationship between these compounds is summarized in the following structural formula and table of substitutions.

=Clavines=
A variety of modifications to the basic ergoline are seen in nature, for example '''agroclavine''', '''elymoclavine''', '''lysergol'''. Those deriving from '''dimethylergoline''' are referred to as '''clavines'''.

=Others=
Some synthetic ergoline derivatives do fall easily into any of the above groups. Some examples are:

* '''Pergolide''' (International Nonproprietary Name/INN)
** IUPAC name: (8beta)-8-((methylthio)methyl)-6-propyl-ergoline
** CAS number: 66104-22-1
* '''Lisuride''' (International Nonproprietary Name/INN)
** IUPAC name: 3-(9,10-didehydro-6-methylergolin-8alpha-yl)-1,1-diethylurea
** CAS number: 18016-80-3

History & Uses
Ergoline alkaloids were first isolated from ergot, a fungus that infects grain and causes the disease ergotism. Ergot also has a long history of medicinal use, which led to attempts to characterize its activity chemistry/chemically. This began in 1907 with the isolation by G. Barger and F. H. Carrin of ergotoxine, so-named since it appeared to exhibit more of the toxicity of ergot than its therapy/therapeutic qualities. With the isolation of '''ergotamine''' in 1918 by A. Stoll came the first therapeutic use of isolated ergoline alkaloids.

With the determination of the basic chemical structure of the ergot alkaloids in the early 1930s, an era of intensive exploration of synthetic derivatives began. In addition to the naturally occurring '''ergonovine''' (used as an oxytocic) and '''ergotamine''' (an analgesic used to control migraine), synthetic derivatives of continuing importance today are the oxytocic '''methergine''', the anti-migraine drugs '''dihydroergotamine''' and '''methysergide''', the anti-senility nootropic (smart drug) '''Hydergine'''™ (a mixture of dihydroergotoxine mesylates, International Nonproprietary Name/INN: ergoline mesylates), and '''bromocriptine''', used for numerous purposes including treatment of Parkinson's disease. Newer synthetic ergolines used for Parkinson's disease include '''pergolide''' and '''lisuride'''. Perhaps the most famous ergoline derivative of all is the psychedelic drug '''LSD'''.

In 1960, Albert Hoffman (discoverer of methergine, dihydroergotamine, Hydergine and LSD) delivered a speech that was to cause shockwaves of incredulity and even disbelief in the scientific community. Ergoline alkaloids, previously only known from the lower fungi, had been found in two species of flowering plants. These were the mexico/Mexican species ''Rivea corymbosa'' and ''Ipomoea violacea'' of the Convolvulaceae (morning glory) family, the seeds of which were identified as the psychedelic plant drugs known as "ololiuhqui" and "tlitliltzin". Hoffman's result was later confirmed by other studies. The principal alkaloids in the seeds are ergine and its optical isomer isoergine, with several other lysergic acid derivatives and clavines present in lesser amounts. The Hawaiian species ''Argyreia nervosa'' was later found to include similar alkaloids. It is possible, though not proven, that ergine and/or isoergine are responsible for the hallucinogenic effects.
