摘要: 以白树(Suregada glomerulata)中分离得到的五个氮杂糖成分为底物,在其N上衍生合成,分析N上衍生基团对α-葡萄糖苷酶抑制活性的影响。分别合成了N-甲基化、N,N-二甲基化、N-丁基化和N-氧化衍生物,体外测试化合物的α-葡萄糖苷酶抑制活性。合成了7个未见文献报道的目标化合物,结构经1H NMR、13C NMR和MS确证。初步药理结果显示,所有衍生物均未见增强α-葡萄糖苷酶抑制活性。N-取代基对活性的影响较大;化合物5属于N,N-二取代衍生物,仍具有一定的α-葡萄糖苷酶抑制活性,值得进一步研究。

Abstract: To synthesize the N-derivation of azasugars isolated from Suregada glomerulata.To analyze the N-substituent group affect the inhibit activity of α-glucosidase.N-methyl,N,N-dimethyl,N-butyl and N-oxidate derivatives were synthesized,and the bioactivity was tested in vitro aganist α-glucosidase.Seven compounds were synthesized,and the structure was confirmed by 1H NMR,13C NMR and MS.The preliminary pharmacological test results showed that all derivatives did not enhance the inhibitory activity.Compound 5,a N,N-derivative,possessed inhibitory activity against α-glucosidase,which is worthy for further study.

Key words: azasugar, Suregada glomerulata, &alpha, -glucosidase, inhibitory activity
