zwitterions was achieved by prodrugs susceptible to cleavage by carboxylesterase 1. The synthesis of select tetrazole prodrugs was crucial. A cell‐free in vitro translation assay containing human cell lysate and purified target mRNA fused to a reporter was used to identify active zwitterions. In vivo PCSK9 lowering by oral dosing of the candidate prodrug and quantification of the drug fraction delivered to
靶向人类核糖体是一种前所未有的治疗方式,具有全基因组选择性挑战。描述了一种以肝脏为靶点的候选药物,可抑制PCSK9的核糖体合成,PCSK9是一种小分子难以吸收的脂质调节剂。该概念的关键是鉴定保留在肝脏中的药理活性两性离子。通透性差的两性离子的口服给药是通过易于被羧酸酯酶1裂解的前药实现的。选择四唑前药的合成至关重要。使用包含人细胞裂解物和与报道分子融合的纯化靶mRNA的无细胞体外翻译测定法来鉴定活性两性离子。18 F-同位素论证明了我们的肝靶向方法。
