Synthesis and Antiviral Activities of Novel Pyrrolo[2,3-d]pyrimidine Monophosphate Compounds
摘要:
以4-取代-9-(2′-脱氧-2′-β-氟-β-D-呋喃糖基)吡咯[2,3-d]嘧啶类化合物为原料,与三氯氧磷一锅法合成出具有新型结构的吡咯[2,3-d]嘧啶核苷单磷酸酯类化合物,其化学结构经核磁共振磷谱(31P NMR)、核磁共振氢谱(1 H NMR)、高分辨质谱(HRMS)分析确证;对合成的目标化合物进行了初步的体外抗乙肝病毒药理活性实验,结果显示设计合成的7个化合物对乙型肝炎病毒表面抗原(HBsAg)和乙型肝炎e抗原(HBeAg)都有一定的抑制作用,其中化合物3a,3d,3f对HBsAg和HBeAg的抑制率较高,3a的毒性较低.
Pyrrolo [2,3-d] pyrimidine monophosphate compounds were synthesized vio one-pot reaction by 4-substituted- 9-(2-deoxy-2,-(3-fluorine-(3-D-furan glycosyl) pyrrolo [2,3-d] pyrimidine with phosphorus oxychloride in sequence. The products were characterized by Nuclear magnetic resonance phosphorus spectrum (31 P NMR), Nuclear magnetic resonance H spectra ((NMR) and High resolution mass spectrometer (HRMS). Preliminary pharmacological test was made on hepatitis B virus (HBV). The test results showed the inhibitory rate of targeted compounds on hepatitis b virus surface antigen (HBsAg) and hepatitis Be antigen (HBeAg) was normal, but the inhibition rate of 3a, 3d, 3f were higher than others and 3a had lower toxic-ity than others compounds.
