Use | 2 '-deoxyguanosine monohydrate is a purine nucleoside with various biological activities. It inhibits the formation of HL-60 and K562 leukemia cells (IC50s = 80 and 100 μM, respectively). When used at a concentration of 50 μM, the growth inhibition of 2 '-deoxyguanosine on MOLT-4 T cells and MGL-8 B cells was 99.8% and 68.3%, respectively. |

Use
2 '-deoxyguanosine monohydrate is a hydrate of 2'-deoxyguanosine. 2 '-deoxyguanosine is an important raw material for the synthesis of oligodeoxynucleotides and other antiviral and anti-tumor nucleic acid drugs.
Application example 2 '-deoxyguanosine is a natural deoxynucleoside, which can be directly used to prepare combined deoxynucleoside drugs or as a chemical reagent for biochemical research; at the same time, it can be used as an intermediate to synthesize some antiviral nucleoside drugs and molecular markers, such as literature (Journal of Medicinal Chemistry,1985, 28:1194-1198) Synthesis of 8-bromo-2'-deoxyguanosine and 8-hydroxy -2'-deoxyguanosine from 2 '-deoxyguanosine and other important molecular markers; The 6-position derivative of 2'-deoxyguanosine is reported in the literature (Tetrahedron Letters,1982,23 (22):2253-2256,1982 Tetrahedron Letters,1990,31(3):319-322), such as 6-methoxy, 6-amino and other important anti-tumor 2 '-deoxyguanosine derivatives; In addition, Chinese patent CN201110114010 publicly reported the use of 2'-deoxyguanosine as raw material to synthesize an important molecular marker N7-guanosine alkylate in the carcinogenic or anti-cancer process.
Preparation
In a 250ml triangular flask, 50ml of culture medium was filled, which contained 1% beef extract, 1% peptone, 0.5% yeast extract, NaCl 0.5%,pH 7.0, sterilized at 118 ℃ for 30min, cooled, fed with acetylbrevis QD96, cultured at 30 ℃ (200r /min) for 16h, the culture medium was frozen and centrifuged at 4000r /min for 30min, washed with 0.05mol/L phosphate buffer (pH7.0), and then centrifuged, the obtained bacteria are stored in cold storage and used as nucleotide phosphorylase for later use.
in a 100ml round bottom flask, 50ml substrate solution is filled, the concentrations of guanylate and thymidine are 40mol/L respectively, the phosphate buffer is 25mmol/L, the amount of bacteria added is 5% (wet weight), the reaction is stirred at 60 ℃ in a constant temperature water bath for 2 hours, the reaction is completed, and the bacteria and a small amount of thymine precipitate are removed by freezing centrifugation. Then the solution contained 24mmol/L deoxyguanosine by HPLC, and the conversion rate reached 60%. 0.26g deoxyguanosine can be obtained by anion exchange resin separation.
Bioactive 2 '-Deoxyguanosine monohydrate is an endogenous metabolite.
