시틴딘-5'-모노인산염, 디나트륨 염

개요Cytidine 5'-monophosphate disodium salt (5'-CMPNa2) is an organic sodium salt that can be used as a pharmaceutical active ingredient. 5'-CMPNa2 can be used with UMP-Na2, vitamin B6, lipoic acid, and magnesium lactate dihydrate to prepare a capsule-type compound drug for the treatment of polyneuropathy[1].

용도Cytidine 5′-monophosphate disodium salt has been used: in nucleotide stock solutionas an ectonucleotidase (ENTase) inhibitor to probe 5′-ENTase activity in cortical neuronsin in vitro studies to estimate its effect on growth response of selected bacteria strains that dominate the piglets′ small intestine

생산 방법The production method of Cytidine 5'-monophosphate disodium salt comprises the following steps: a. adding cytidine, triethyl phosphate and pyridine into a reaction container respectively, and adjusting the reaction temperature to -15-5°C after mixing evenly, and slowly adding a certain amount of phosphorus oxychloride under the temperature condition, and continuing to stir and react for 10-30h after adding; b. taking samples for HPLC analysis, and when the conversion rate is ≥99%, adding 10-15% ice salt water for hydrolysis, and the hydrolysis temperature is controlled to be 0-5°C, and the hydrolysis time is 10-20h; c. after the hydrolysis is completed, standing and stratifying, removing the organic phase, and obtaining a water layer for standby use; d. adjusting the pH of the water layer to 7.0-8.0 with 30% sodium hydroxide, and then dripping 95% alcohol twice the volume of the solution, precipitating crystals, and filtering to obtain a crude product. e. dissolving the crude product, adding activated carbon for decolorization, and continuing to drip 95% alcohol twice the volume of the solution to precipitate crystals, filtering, rinsing, and drying to obtain the finished product Cytidine 5'-monophosphate disodium salt.
