Uridine synthesis

12synthesis methods
Cytosine nucleoside (or uracil nucleoside) and adenine nucleoside are used as main raw materials, and uridine is obtained through the transformation of biological cell homogenate, and then microfiltration, precipitation, chromatography and crystallization
-

Yield:58-96-8 99%

Reaction Conditions:

with cytidine deaminase enzyme in aq. phosphate buffer at 37; pH=7; for 0.0833333 h;Enzymatic reaction;

Steps:

1 Comparative Example 1 : Deamination of cytidine (compound 1 ) to uridine

Comparative Example 1 : Deamination of cytidine (compound 1 ) to uridine A 100 mM solution of the cytidine (495 μΙ) in 100 mM phosphate buffer at pH 7 was mixed with 50 L of cytidine deaminase enzyme solution containing >300 AU in phosphate buffer. The reaction was performed at 37°C during 5 minutes and stopped with HCI. Then, the crude reaction was filtered through a 10 KDa membrane, and a portion was diluted and analyzed by HPLC under UV-DAD (ultraviolet-diode array detection). Product identification was performed by comparison to a standard sample. Uridine was obtained in quantitative yield (>99%).
