exhibited equipotent inhibitory activity against not only influenza A virus sialidase but also influenza A virus in the cell culture. Next, we synthesized poly-L-glutamine bearing 7-O-alkyl-4-guanidino-Neu5Ac2en derivatives linked by amide bonds, 26, which showed enhanced antiviral activity against influenza A virus and more potent efficacy in vivo relative to a monomeric sialidase inhibitor.
描述了在聚-L-谷氨酰胺主链上带有4-胍基-Neu5Ac2en衍生物的多价唾液酸酶抑制剂。为了更长的4-胍基-Neu5Ac2en(扎那米韦)在支气管和肺中的保留时间,我们集中研究了带有4-胍基-Neu5Ac2en衍生物通过不可裂解的烷基醚键键合在其C-7位的超分子。我们首先发现唾液酸衍生物8的7-羟基的烷基化进展顺利,并产生了7-O-烷基-4-胍基-Neu5Ac2en衍生物13,其不仅对甲型流感病毒唾液酸酶而且对流感都表现出同等的抑制活性。细胞培养物中的病毒。接下来,我们合成了带有通过酰胺键连接的7-O-烷基-4-胍基-Neu5Ac2en衍生物的聚L-谷氨酰胺26,
