Benzoic acid and pyridine derivatives inhibit recombinant trans-sialidase from Trypanosoma cruzi with I50 values between 0.4 and 1mM. The best compounds, 4-acetylamino-3-hydroxymethylbenzoic acid and 5-acetylamino-6-aminopyridine-2-carboxylic acid, provide new leads to inhibitors not containing the synthetically complex sialic acid structure. The weak inhibition by such compounds contrasts with their
苯甲酸和吡啶衍生物抑制克氏锥虫的重组反唾液酸酶,I50值为0.4至1mM。最好的化合物,4-乙酰氨基-3-羟甲基苯甲酸和5-乙酰氨基-6-氨基吡啶-2-羧酸,为不含合成复杂唾液酸结构的抑制剂提供了新的线索。这类化合物的弱抑制作用与其对流感病毒对神经氨酸酶的抑制作用相比要强得多。
