以D-阿拉伯糖衍生的环状硝酮7和硝酮衍生的醛4为原料,采用立体互补策略,合成了4种非对映异构体,包括:藜芦碱(1),6-表藜芦碱(2),7-表藜芦碱(13)和6,7-二表藜芦碱(14)。糖苷酶抑制比较表明,6-表木麻黄碱(2)对海藻糖酶具有增强的抑制作用(IC 50 = 9.7 μM),而6,7-二表木麻黄碱(14)对海藻糖酶具有特异性抑制作用。
Four diastereomers belonging to the family of casuarines, including casuarine (1), 6-epi-casuarine (2), 7-epi-casuarine (13) and 6,7-diepi-casuarine (14), have been synthesized from D-arabinose-derived cyclic nitrone 7 and nitrone-derived aldehyde 4 by a stereocomplementary strategy. Glycosidase inhibition comparison showed that 6-epi-casuarine (2) exhibits enhanced inhibition of trehalase (IC50 = 9.7 μM) and 6,7-diepi-casuarine (14) leads to specific inhibition of trehalase.
