| 中文摘要:目的:设计、合成新型抗乙型肝炎病毒的开环核苷膦酸类似物。方法:根据阿德福韦(PMEA)的结构特点,采用生物电子等排体理论,引入8-氮杂-6-取代苯硫基嘌呤,设计、合成系列目标化合物。化合物结构经IR,1H-NMR谱进行确证。对1 a-1 e化合物进行了体外抗HBsAg、HBeAg和抗HBV-DNA活性筛选试验。结果:设计合成了10个目标化合物;所测化合物抗HBsAg、HBeAg活性均好于PMEA,化合物1 e抗HBV-DNA活性与PMEA相当,值得继续研究。结论:PMEA引入8-氮杂-6-取代苯硫基嘌呤抗HBV-DNA活性保持,抗HBsAg、HBeAg活性提高。 |

| Abstract:ObjectiveTo study of design and synthesis of the novel acyclic nucleoside phosphonates analogues and study their activities of inhibiting HBV.Methods Based on the chemical structure of PMEA,and according to the theory of bioisostere,a 8-aza-6-thiophenyl group was introduced and a series of title compounds were synthesized.All of them were confirmed by IR,1H-NMR and MS.Preliminary pharmacological test of compounds 1a-1e was made on HBV.Results Ten compounds were synthesized.The test Results show the inhibitory rate of 1a-1e compounds on HBsAg and HBeAg is higher than PMEA.The inhibitory rate of compound 1e on HBV-DNA is correspond with PMEA.Conclusion The PMEA derivatives with a 8-aza-6-thiophenyl group have high activity on inhibiting HBsAg,HBeAg and HBV-DNA. |
