Chemistry:Propisergide

From HandWiki

Propisergide (INN; developmental code name PML-946), also known as ergalgin or as N-methylergometrine or 1-methylergometrine, is a serotonin receptor modulator and antimigraine agent of the ergoline and lysergamide families which was never marketed.[1][2][3][4][5] It is the 1-methyl derivative of ergometrine (ergonovine) and is a close analogue of methylergonovine and methysergide (UML-491).[6][4][7] Extensive metabolism of other 1-methylated lysergamides to their secondary amine derivatives, for instance methysergide (1-methylmethylergometrine) conversion into methylergometrine, has been observed.[8][9] Propisergide has 259% of the antiserotonergic activity of LSD.[6][10] Its average clinical dose range for preventative treatment of migraine is 1 to 3 mg orally.[10] Propisergide was first described in the literature by 1958[6][11] and then further around 1980 and after.[5][12][13]

Methylergometrine (one of methysergide’s metabolites) is responsible for methysergide’s therapeutic effects regarding migraine treatment (Müller-Schweinitzer and Tapparelli 1986). [...] The systemic availability of methysergide after oral administration is only 13%, due to a high degree of first-pass metabolism by N-1 demethylation to methylergometrine. After oral administration, the plasma concentrations of the metabolite are considerably higher than those of the parent drug, and the area under the plasma concentration curve (AUC) for methylergometrine is more than ten times greater than for methysergide."
