| CYTIDINE 5'-DIPHOSPHOCHOLINE Usage And Synthesis |
| Description | Citicoline whose chemical name choline cytosine nucleoside-5'-diphosphate monosodium salt, is a precursor for lecithin biosynthesis, and when brain function declines, the content of lecithin in brain tissue is significantly reduced. | | Originator | Nicholin,Cyanamid,Italy,1971 | | Uses | Cytidine 5'-Diphosphocholine is used as antidepressant, 5HT uptake inhibitor. | | Manufacturing Process | A 250 ml conical flask containing 30 ml of a reaction liquor (pH 7.0) having a
composition of 7.38 mg/ml of disodium salt of CMP (cytidine-5'-
monophosphate), 24 mg/ml of choline, 10 mg/ml of glucose, 100 mg/ml of
acetone-dried cells of Brevibacterium ammoniagenes ATCC 6872, 11.6 mg/ml
of monopotassium phosphate, 20 mg/ml of dipotassium phosphate and 2.96
mg/ml of magnesium sulfate, (MgSO4·7H2O), was subjected to culturing at
30°C for 4 hours. Cytidine diphosphate choline was formed and accumulated
at a concentration of 3.8 mg/ml in the culture liquor.
The pH of 1.2 liters of filtrate containing 3.8 mg/ml of cytidine diphosphate
choline, obtained by removing solid matters from the culturing liquor, was
adjusted to a pH of 8.5 with a 0.5 N KOH solution. The filtrate was passed
through a column of strongly basic anion exchange resin, Dowex 1 x 2 (formic
acid type). After washing the resin with water, a formic acid solution was
passed through the column with gradual increase in the concentration of
formic acid (until 0.04 N max.). A fraction of cytidine diphosphate choline was
collected by elution according to the so-called gradient elution method and
absorbed onto carbon powders. Then, elution was effected with acetone, and
the eluate was concentrated and dried. 1.3 g of cytidine diphosphate choline
powders were obtained. | | Therapeutic Function | Cerebral circulation stimulant |
