摘要
为了控制瑞加德松的产品质量,本研究发现并合成了瑞加德松3个有关物质:2-(4-羧基-1H-吡唑-1-基)腺苷(A),2-(4-甲胺羰基-1H-吡唑-1-基)-N6-甲基腺苷(B),1-(6-氨基-9H-嘌呤-2-基)-1H-吡唑-4-甲酰甲胺(C),并经MS、1H NMR和13C NMR确证结构。
To perform the quality control of regadenoson, three related substances were prepared and their structures were confirmed by MS, 1H NMR and 13C NMR. These substances were 2-(4-carboxyl-lH-pyrazol-1- yl) adenosine (A), 2- [4- E (methylamino) carbonyl] - 1H-pyrazol- 1-yl~ -N6-methyladenosine (B), and E 1- (6-amino-9H- purin-2-yl) - 1H-pyrazole-4-yl~ -N-methylcarboxamide (C).
