The present invention provides new compositions and methods for preventing and treating pathogen infection. In particular, the present invention provides compounds having an anchoring domain that anchors the compound to the surface of a target cell, and a therapeutic domain that can act extracellularly to prevent infection of the target cell by a pathogen, such as a virus. Preferred target cells are epithelial cells. The invention provides compositions and methods for preventing viral diseases, such as influenza, using compounds having anchoring domains that can bind target cells linked to enzymatic activities that can act extracellularly to interfere with viral infection of target cells. The invention also provides compositions and methods for preventing viral diseases such as influenza using compounds having anchoring domains that can bind target cells linked to protease inhibitors that can act extracellularly to interfere with viral infection of target cells.
本发明提供了预防和治疗病原体感染的新组合物和方法。特别是,本发明提供的化合物具有锚定结构域和治疗结构域,前者可将化合物锚定在靶细胞表面,后者可在细胞外发挥作用,防止病毒等病原体感染靶细胞。首选的靶细胞是上皮细胞。本发明提供了预防流感等病毒性疾病的组合物和方法,使用的化合物具有锚定结构域,该结构域可结合靶细胞,并与可在细胞外发挥作用干扰靶细胞病毒感染的酶活性相连。本发明还提供了利用具有锚定结构域的化合物预防流感等病毒性疾病的组合物和方法,这些锚定结构域可与蛋白酶抑制剂相连,蛋白酶抑制剂可在细胞外发挥作用,干扰病毒对目标细胞的感染。
