The synthesis of a series of analogues of the α-glucosidase inhibitor 1-deoxynojirimycin (dNM, 1) and of the α-mannosidase inhibitor 1-deoxymannojirimycin (dMM, 3) is described. The ability of dNM, dMM and a series of N-alkylated dNM and dMM derivatives to interfere with biosynthesis, transport and maturation of the glycoprotein α1-antitrypsin in human hepatoma HepG2 cells and with the syncytium-inducing
描述了α-葡糖苷酶抑制剂1-脱氧野oji霉素(dNM,1)和α-甘露糖苷酶抑制剂1-脱氧甘露菌霉素(dMM,3)的一系列类似物的合成。DNM,DMM的能力和一系列Ñ烷基化DNM和DMM衍生物与糖蛋白α的生物合成,转运和成熟干涉1抗胰蛋白酶在人肝癌HepG2细胞,并用HIV感染细胞的合胞体诱导能力为调查。观察到在HepG2细胞中发现的α-葡萄糖苷酶抑制与在HIV-1感染的细胞中的抗病毒活性之间存在很强的相关性。N-丁基-(35),N-戊基-(38),N-苄基-(41)和N-癸基-dNM(47)在两种测定中均显示高活性。N-癸基-dNM在0.01 mM时有活性,但在浓度超过0.1 mM时显示药物相关的细胞毒性。N-烷基侧链的分支显着降低了dNM衍生物的活性。N-苄基-6-O-丁酰基-dNM(42)和N-癸基-6- O-苯甲酰基-dNM(48)显示的活性与N-苄基-dNM(41)和N-癸基-dNM(41)相当47),
