多价结合,即多个配体与多个受体的同时结合,在许多病理过程中发挥了核心作用,包括病毒、寄生虫、支原体和细菌病原体的附着。[1]这些生物活性已被广泛研究,以促进特定细胞类型的靶向,[2]生物多价抑制剂已使结合亲和力显著增加1 - 9个数量级。[3]特别是,纳米级的聚(酰胺基胺)(PAMAM)树枝状聚合物已被报道是一个很好的介体促进多价效应,由于它们的能力,预组织/定向配体和容易变形的聚合物链。[2a]
Multivalent binding, the simultaneous binding of multiple ligands to multiple receptors, has played a central role in a number of pathological processes, including the attachment of viral, parasitic, mycoplasmal, and bacterial pathogens.[1] These biological activities have been extensively investigated to promote targeting of specific cell types,[2] and biological multivalent inhibitors have yielded significant increases in binding avidities by 1–9 orders of magnitude.[3] In particular, nano-scale poly (amidoamine)(PAMAM) dendrimers have been reported to be an excellent mediator for facilitated multivalent effect due to their capability to pre-organize/orient ligands and easy deformability of the polymer chains.[2a]
