摘要:
Pergolide is produced from 8,9-dihydroelymoclavine by a one-pot process in which it is reacted successively with 1-iodopropane, with a sulfonyl halide, and with an alkali metal thiomethoxide without isolation of intermediate products.
摘要:
The present invention relates to a drug for human use, having contraceptive and menstrual cycle controlling properties, characterized in that the said drug comprises N-acetyl-5-methoxytryptamine or melatonin, in a dose of 100-200 mg pro die, N-acetyl-2-bromo-5-methoxytryptamine or 2-bromomelatonin in a dose of 25-50 mg pro die N-acetyl-2-iodo-5-methoxytryptamine or 2-iodomelatonin, in a dose of 20-40 mg pro die, in association with a progestinic compound. The administration is carried out for 23 days, by using an association of 2-iodomelatonin and/or melatonin and/or 2-bromomelatonin and a progestinic compound, followed by 5 days in which only 2-iodomelatonin and/or melatonin and/or 2-bromomelatonin is administered; the drug having oncostatic preventive and therapeutic properties, in mammary tumours and melanomas, characterized by the use of 2-iodomelatonin, melatonin and 2-bromomelatonin respectively with doses of 20-40 mg, 100-200 mg, 25-50 mg pro die; and the said drug having moreover antikinetosic properties, and being characterized by the use of 2-iodomelatonin in a dose pro die of 2.5 mg, melatonin, in a dose pro die of 10 mg and 2-bromomelatonin in a dose pro die of 3.5 mg, either individually and/or in association with the acetyl coenzime A-(AcCoA), in a dose of 8-10 mg pro die.
摘要:
Ergoline derivatives containing the L-proline moiety and some derivatives thereof having dopaminergic activity, the processes for the preparation thereof and pharmaceutical compositions containing them.
摘要:
Ergoline Esters I (R₁=H or CH₃; R₂=C₁-C₄ hydrocarbon; R₃=H or OCH₃; R₄=H or halogen; R₅=C₁-C₄ alkyl) and their pharmaceutically acceptable salts are active in the central nervous system level. A process for their preparation is also described. The ergoline esters and their salts can be used for the making of pharmaceutical compositions being effective against cerebral insufficiency and senile dementia.
摘要:
Ergoline derivatives of general formula I wherein either R₁ represents a hydrogen atom or a methoxy group and R₂ represents a hydrogen atom or R₁ and R₂ taken together represent a chemical bond, and R₃ represents a hydrogen atom, an unsubstituted or substituted nicotinoyl group or a 1-oxo-2-cyclopenten-3-yl group; or a pharmaceutically acceptable salt thereof are active at the Central Nervous System level and useful therefore in the treatment of cerebral insufficiency and senile dementia.
