Description

PHARMACEUTICAL COMPOSITIONS COMPRISING MONOCHOLINE
SUCCINATE SALTS
Field of the Invention
The invention relates to the use of monocholine salts of succinic acid in pharmaceutical compositions, particularly in compositions with a neuroprotective activity.
Background of the invention
Monocholine salt of succinic acid is known from the prior art and is disclosed, for example, by published US patent 5,124,061 as a component of compositions for increasing the resistance of plants to damage by freezing conditions.
However, there are no data in the art on the use of monocholine salt of succinic acid as an active component in pharmaceutical compositions.
Surprisingly, it is demonstrated in the present invention that monocholine salts of succinic acid manifest a pronounced effect on brain function and can be used as an active component in pharmaceutical compositions.
It is an object of the present invention to provide a pharmaceutical composition comprising a therapeutically effective amount of monocholine salts of succinic acid.
Detailed Description of the Invention The present invention provides a pharmaceutical composition comprising a therapeutically effective amount of a compound of Formula (I)

Example 6.
This example demonstrates efficacy of compositions of the invention for the treatment Alzheimer's disease.
A disease relevant to human Alzheimer's disease was induced by injection of beta-amyloid peptide 25-35 (beta-amyloid) into nucleus basalis magnocellularis (NBM) of rat brains as described by Harkany T et al. in Behav Brain Res. 1998 90(2^:133-45. Beta-amyloid was administered bilaterally into NBM of male Wistar rats in dose of 2 μg per each side. On day 16th after the amyloid injection, rats received intraperitoneally compositions comprising a water solution of compounds of formula (I), (II), (III), or (IV), once-a-day for 7 days in dose of 10 mg/kg. Control rats received saline intraperitoneally. Ony week after the last day of the treatment, passive avoidance performance in rats was tested for two consecutive days. A two-compartment, step-through, passive avoidance apparatus consisting of illuminated (25 x 40 x 25 cm) and dark (25 x 40 x 25 cm) compartments attached to an electrified grid floor and separated by a guillotine door (8 x 8 cm) was used. In the acquisition trial, the rat was placed in the illuminated compartment in a position its tail directed to the closed door for 2 min to habituate to the apparatus. The guillotine door was opened and time to enter to dark compartment was recorded. When the rat entered to dark compartment completely (four foots in dark compartment), the guillotine door was closed and the rat was delivered an electrical shock of 0.8 niA for 3 sec through the grid floor. After the shock, the rat was immediately placed in home cage. In the retention trial, conducted 24 h after the acquisition trial, the rat was placed in the illuminated compartment and the retention latency to enter into the dark compartment was recorded until 180 s had elapsed. The latency was accepted for 180 s, if the rat did not enter the dark compartment for 180 s. Data are presented as retention latency mean ± SD (n=10).
