Usage

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.

Improved synthesis of cytidine diphosphate choline (CDP-choline) via selective phosphorylation

An improved, three-step synthesis of cytidine diphosphate choline (CDP-choline) from cytidine was achieved in 68% overall yield. Selective phosphorylation of cytidine was accomplished by the use of morpholinophosphodichloridate to give cytidine-5′-phosphomorpholide, which was condensed with choline phosphate chloride in the presence of a catalytic amount of H2SO4 to give CDP-choline. The intermediates and products could be efficiently purified by recrystallisation, thus avoiding the use of chromatography at all stages. The reaction could be scaled up to 200 g in 64% overall yield, making this route attractive for industrial application.

Citicoline and synthesizing method of citicoline not using phosphocholine chloride calcium

The invention discloses citicoline and a synthesizing method of citicoline not using phosphocholine chloride calcium. The synthesizing method does not use phosphocholine chloride calcium, and comprises the following three steps of using dichloride phosphoryl morpholine with low cost and easy obtaining as a raw material, and reacting with ethylene glycol, so as to obtain glycol ester phosphoryl morpholine; continuously and directly is in condensation with cytidine monophosphate, so as to obtain glycol ester phosphoryl cytidine monophosphate; finally, opening a loop of gylcol ester of the glycol ester phosphoryl monophosphate by tributylamine, so as to obtain the citicoline, wherein the total yield is 78 percent. The synthesizing method has the advantages that the cost of raw material is low, and the obtaining is easy, so that the use of DCC (dicyclohexylcarbodiimide) and phosphocholine chloride calcium with high cost and toxicity is avoided; when the reaction scale is expanded to 500g, the yield is not obviously decreased; a new synthesizing path is provided for the synthesis of the citicoline, and the potential application prospect is realized.
