5-dideoxy-9-methylphosphono-2-propyl-alpha-D- glycero-D-galacto-nonulopyranosidonic acid triethylammonium salt (2), and 5-acetamido-9-thiomethylmercuric-3, 5,9-trideoxy-beta-D-glycero-D-galacto-nonulopyranosidonic acid (3) were synthesized. Compounds 1 and 2 are proposed transition state inhibitors of an esterase vital for the binding and infection of influenza C. Compound 3 was enzymatically incorporated into
已经开发出用于酶促合成唾液酸部分中含有重金属汞或流感C 9-O-乙酰基神经氨酸酯酶催化的过渡态类似物膦酸酯的复杂碳水化合物和糖蛋白的酶促方法。5-Acetamido-3,5-dideoxy-9-methylphosphono-beta-D-glycero-D-galacto-nonulopyra nosidonic acid(1),5-acetamido-3,5-dideoxy-9-methylphosphono-2-propyl-alpha -D-甘油-D-半乳糖-壬基吡喃二磺酸三乙基铵盐(2)和5-乙酰氨基-9-硫代甲基汞-3、5,9-苯氧基-β-D-甘油-D-半乳糖-壬基吡喃二磺酸(3)是合成的。化合物1和2是对C型流感病毒的结合和感染至关重要的酯酶的过渡态抑制剂。
