2,3,4-三-O-乙酰基-b-D-木吡喃糖基异硫氰酸酯1与2-氨基-4/6-取代-苯并噻唑2a~2e反应, 生成糖基硫脲衍生物3a~3e, 再在伯胺存在下经氯化汞脱硫, 得到一系列新的胍基木吡喃糖苷类化合物4a~4e, 5a~5e, 6a~6e, 7a~7e, 所有新化合物的结构均经IR, 1H NMR, MS谱和元素分析证实, 所得产物均为β-构型. 生物活性测试结果表明, 化合物4c, 5b, 6b~6d, 7b等对HIV-1蛋白酶表现出了较高的抑制活性.

The reaction of 2,3,4-tri-O-acetyl-b-D-xylopyranosyl isothiocyanate 1 and 2-amino-4/6-substituted benzothiazoles 2a~2e gave xylopyranosylthioureas 3a~3e, which then reacted with alkyl/aryl amine in the presence of HgCl2 to afford a series of new guanidinoxylopyranosides (4a~4e, 5a~5e, 6a~6e and 7a~7e). The structures of the new compounds were established on the basis of elemental analyses, IR, 1H NMR and mass spectral data and all compounds took b-configuration. The biological activities of these compounds have been evaluated. Compounds 4c, 5b, 6b~6d and 7b showed anti-HIV-1 PR activity.

Key words: xylopyranosyl isothiocyanate, xylopyranosylthiourea, guanidinoxylopyranoside, anti-HIV-1 PR activity
