PSP pacDNA, is prepared using solid-phase and graft-onto methodologies. Consisting of a polyphosphodiester backbone and poly(ethylene glycol) side chains, the PSP pacDNA suppresses non-specific interactions with the cell and improves the plasma pharmacokinetics of the aptamer. Combined with a thrombin-binding aptamer, the PSP pacDNA produces a pronounced anticoagulation effect in vivo.
使用固相和移植方法制备了一种瓶刷聚合物-适体生物杂交体,称为 PSP pacDNA。 PSP pacDNA 由聚磷酸二酯主链和聚乙二醇侧链组成,可抑制与细胞的非特异性相互作用,并改善适体的血浆药代动力学。 PSP pacDNA 与凝血酶结合适体结合,在体内产生显着的抗凝作用。
