摘要:
The present invention relates to novel quinolinone derivatives (I), efficacious in animal models of CNS disorders and, as such, valuable candidates for the prevention or treatment of CNS (Central Nervous System) diseases or disorders. In other aspects the invention relates to pharmaceutical compositions comprising the quinolinone derivatives of the invention and to the use of these compounds for therapeutic applications.
摘要:
The invention concerns a new process for the preparation of naphthoquinones, in particular an improved process for the preparation of 2,3-disubstituted 1,4-naphthoquinones, in the trans configuration.
摘要:
This invention relates to the preparation of (R)-(−)-3-(carbamoylmethyl)-5- methylhexanoic acid, in particular, the resolution of the acid racemate by means of salification with optically active amines and subsequent acidification to give the (R) enantiomer of the acid; this invention also concerns the salt intermediates formed with said amines and the conversion of said (R)-(−)-3-(carbamoylmethyl)-5- methylhexanoic acid into biologically active molecules such as pregabalin.
摘要:
Lipoic acid pellets are described, obtained from inert cores externally coated with lipoic acid. The so obtained active cores are coated with a first layer of insulating polymeric material and then with a polymeric coat that is insoluble at the gastric pH. Pellet are then formulated pharmaceutically, for instance in jelly capsules or controlled release capsules or as oral suspensions, dispersible powders, sachets, etc.
摘要:
Salt of thioctic acid with L-carnitine with the formula: AY(X)x where A is where Y is the cation of an alkaline metal, of an alkaline earth metal or is a quaternary ammonium group, X is A or OH−, x is equal to 0 when Y is the cation of an alkaline metal or a quaternary ammonium group and equal to 1 when Y is an alkaline earth metal.
摘要:
A process for the preparation of 2-amino-1,3-propanediol comprising the catalytic hydrogenation of 1,3-dihydroxyacetone oxime in the presence of rhodium supported on alumina is described.
摘要:
The present invention concerns a new composition based on pellets of lipoic acid in a lipophilic medium, if necessary combined with other active ingredients.
摘要:
The invention concerns a new polymorphic form of R-(+)-α-lipoic acid and a process for the preparation thereof, in addition to the compositions that contain it and its use as a medicine or food supplement.
