Abstract

The synthesis and the nidation inhibitory activity (indirect evidence of prolactin activity) of a new class of ergolinyl-acylureas is described. Some structure—activity relationship considerations are also reported. N-[3-(Dimethyl-amino)propyl]-N-[(ethylamino)carbonyl]-6-(2-propenyl)ergoline-8β-carboxamide (laboratory code FCE 21336; international non-proprietary name cabergoline) was the most interesting compound of the series and is now under extensive clinical evaluation in treatment of hyperprolactinemic disorders.

Résumé

Les auteurs ont décrit la synthèse et l'activité inhibitrice de la nidation d'une nouvelle classe d'acylurées d'ergolinyle. En outre, quelques considérations concernant la corrélation entre structure et activité ont été rapportées. Le composé le plus intéressant de la série était l'N-[(diméthylamino)-3 propyl]-N-[(éthylamino)carbonyl](propényl-2)-6 ergoline-carboxamide-8β (code de laboratoire: FCE 21336, dénomination internationale commune: cabergoline) qui est soumis maintenant à une évaluation clinique approfondie.

    Cabergoline (CAB) is an ergot derivative is a long acting dopamine agonist and prolactin inhibitor. Chemically it is called 1((allylergolin-8β-yl)-carbonyl)-1-(3-dimthylamino-proyl)-3-ethyl urea (Scheme 1a) [1,2]. In the pharmaceutical aspects, which is used for the treatment of hyperlactenemic disorder, either idiopathic or prolactinoma (prolactin-secreting adenomas) diseases.

    Another example of an analogue with an aminothiazole moiety is riluzole (Fig. 1), a Na+ channel blocker with neuroprotective activity [27] effective against MPTP-induced neurodegeneration of the nigrostriatal dopaminergic neuronal pathway [28]. In addition, cabergoline, a dopamine D2 receptor agonist which was launched in 1993 as an anti-Parkinson's agent containing urea functionality in its structure [29] while other derivatives such as KHG21834 (Fig. 1) with urea and thiazole moiety were capable of protecting PC12 cells and cortical and mesencephalic neurons from amyloid β-induced degeneration [30]. Likewise, some thiazol-2-yl urea derivatives (e.g. AR-A014418, Fig. 1) are being developed as an inhibitor of glycogen synthase kinase-3β as its dysregulation is implicated in certain psychiatric and neurodegenerative diseases [31,32] and these agents are being considered as a novel strategy to treat PD [33].
